Most people want to be leaner. Sure, some want to gain muscle, but almost everyone wants less body fat. The current data suggests that over 40% of adult males and nearly 60% of adult females are attempting to lose weight every year.1 Perhaps even more staggering, nearly 50% of high school students report attempting to lose weight and in the case of females, that number is even greater at 60%!2 Females tend to be more greatly impacted by ‘diet culture’ than males due to expectations of being thin, feminine, and sexy. Due to this, women will attempt more diets in their lives, in fact a recent survey on college campuses found that 91% of college women had attempted to diet and 22% said that they dieted frequently or ‘all the time.’3 This has led to an extreme focus on weight loss attempts through dieting. Sadly, the intense focus on dieting leads people to completely neglect what happens in the interim between dieting attempts. Diets don’t fail to cause weight loss, in fact the average dieter loses around 5-6kg per attempt.4 If this is the case, then why are we still struggling with an obesity epidemic reaching epic proportions with nearly half the population being overweight or obese?5 This is a complicated question that involves a complex web of physiological, psychological, and sociological aspects of nutrition and mental health. The short answer is that people are really good at losing weight, but they are absolutely terrible at keeping it off. 1. (2018, July 12). Products - Data Briefs - Number 313 - July 2018 - CDC.

An often cited number is that diets have a 95% failure rate. It’s a statistic that we have talked about in previous books, but the more we’ve examined the data, the more we realize that it’s difficult to put an actual number on this statistic. Here’s why: you have to first define what ‘weight loss’ is. Do you consider 10% of body weight loss adequate to be termed ‘successful weight loss.’ What about 2%? Or is it more fitting to say 20%? Many of these studies define successful ‘weight loss’ differently. So when determining ‘weight regain’ it becomes. If you lost 10% of your body weight but then regained 5% back, do we consider you a weight regainer? Or are you someone who successfully kept off 5%? As you can see, defining terms can dramatically impact the data. Furthermore, the time duration studied can make a difference. If we are talking about maintaining a 5% weight loss for say 6 months, there will be a much higher success rate than those who maintained it for 6 years. What is clear in the literature however, is that losing weight (>5% body weight) seems to be accomplished with relative frequency amongst dieters. Keeping it off for several years however, is far more difficult. If we are talking about losing 10% of body weight and keeping it off, then it’s even more difficult. In examining the weight maintenance data beyond 2-3 years from the initial weight loss period, it is clear that the majority of people will regain a significant amount of weight, and many of those will actually end up adding back MORE weight than they initially lost.6 7 There are a multitude of reasons that this occurs including physiological, psychological, and sociological factors and we will cover many of these reasons in the coming chapters. People may quibble over the actual statistics of the failure rates of diets or the regain rates, but no one can dispute that weight regain is a major problem facing those who lose body fat through dieting. One of the major issues in this regard is the fact that people don’t typically lose weight in 6. (n.d.). Weight regain in U.S. adults who experienced substantial ... - NCBI.

If you ask people who are dieting what kind of diet they are on, they will typically reply with some flavor of the month fad diet. Very rarely will you hear “I’m practicing portion control and self-monitoring” because frankly, that isn’t sexy enough for most people. In many ways, human beings are incredibly intelligent. We have put men on the moon, we have unlocked many secrets of the universe, and we have harnessed the power of the atom, but we are also incredibly stupid when it comes to our beliefs about various nutritional fallacies and quackery. If we pose the question “what is THE most important thing for losing fat and keeping it off?” we will hear replies like: “Avoid all sugar and junk food, its addictive and fattening.” “Keep insulin as low as possible. Foods that spike your insulin cause weight gain.” “Train fasted, it keeps your metabolism in the fat burning zone.” “Intermittent fasting, it keeps your metabolism running as fast as possible.” “Avoid carbs after 5pm so you don’t store them as fat.” “Put butter in your coffee. It gives you long lasting energy without the sugar crash.” Now you might think we threw that last one in there as a joke, but it’s actually a thing (sadly). We’ve seen this sold as a keto bomb in many so called ‘healthy cafes’ and while it’s easy to dismiss, none of these responses are correct. The most important thing for losing fat and keeping it off is adherence. You can’t get results if you aren’t consistent with your approach. This isn’t just a feeling of ours, it’s supported by actual data. In fact, when you analyze popular diets versus each other, none of them emerge as being clearly superior to the others for losing fat and keeping it off. In fact, what is most closely associated with INTRODUCTION 6 success is dietary adherence.8 9 10 11 This certainly doesn’t sound sexy and isn’t going to wind up on the cover of a magazine in the checkout line at grocery stores, but it’s the hard truth. The optimal nutrition strategy is a little bit like economics, in that what works for consistently building wealth is pretty darn boring. Save money, live within your means, limit your debt, and don’t make big purchases that depreciate. There are a lot of self help books out there but the one thing no one can deny is that in order to accumulate wealth, you must save more money than you spend overall. That is not what gets attention unfortunately. Weekend courses on how you can make millions ‘easily’ by flipping houses, MLM schemes, pyramid nonsense, and wacky investment strategies are what gets the most attention. In nutrition, giving good advice about choosing a sustainable form of dietary strategy that you can adhere to isn’t sexy. Nonsensical supplements, fad diets, waist trainers, topical gels for fat burning and sculpting, and other such BS are what get the attention. We will promise you that if you talk with people who have lost weight and have kept it off for YEARS, it’s unlikely that they will reference fad diets as the reason for their success. More likely they will talk about changes they made to their lifestyle and dietary behaviors as the key reason for their long term success. We discuss the key behaviors and factors for maintaining weight loss in Chapter 3. Why Reverse Dieting? One of the tough things about maintaining lost body fat is that often times, when people end their diets, the level of calories they are consuming is simply too difficult to sustain. Most people can sustain low calorie diets for a short period of time, but trying to maintain <1500 calories as a long term diet strategy is going to be really challenging. Trust me, this used to be me (Holly speaking)! 8. (2008, February 12). Dietary adherence and weight loss success among ... - NCBI - NIH.

This is where reverse dieting comes in. At the end of a diet where people have achieved their weight loss goal, or at least have decided that they are satisfied enough with their results to stop targeting further weight loss, many people go back to their ‘pre diet’ eating behaviors and regain a lot of the weight as we discussed previously. Even people who are very mindful of tracking their calories will often return back to their ‘pre diet’ maintenance calories in a relatively short period of time. What many people do not realize however is that your maintenance calorie levels after a long diet will be far lower than what equations can predict, even when based off your current anthropometric measurements (i.e. weight, body fat, lean body mass, age, etc). Taking your calories back up to your predicted maintenance or your maintenance calories from before you started your diet will likely lead to weight gain, as your post diet metabolic rate is likely suppressed. We will discuss the mechanisms for this decrease in metabolic rate in Chapter 2, but essentially, your body responds to dieting by reducing your overall energy expenditure in order to defend you against starvation. Consider this, if your body did not adapt to a reduction in calories, then you could simply eat in a small calorie deficit, and over a set period of time, you would lose all your body fat and eventually you would starve to death. This ‘metabolic adaptation’ is a normal response to dieting and something that needs to be considered in order to lose weight and keep it off. So why reverse dieting? Reverse dieting has a myriad of uses and situations where it may make sense, and we will attempt to cover many of them, but the primary use of a reverse diet is for people who want to minimize weight regain while recovering from a long diet and raising their calories back to a more sustainable level. This involves a process of slow and controlled calorie increases in order to minimize fat regain, while at the same time, increase your energy expenditure and metabolic rate. Essentially we want to ‘train’ you to be able to eat more food while not gaining excessive amounts of body fat. Some people may be able to add a significant amount of calories and not regain any body fat whatsoever. So why would someone want to do this? Well most people would probably love to be able to enjoy the flexibility of eating more food and not gain any weight, especially those who have lost weight from dieting. Studies have INTRODUCTION 8 demonstrated that people who have lost weight from dieting have significantly greater hunger levels than weight matched controls who did not lose weight.12 13 This increase in hunger is thought to be about 3 fold higher than the corresponding amount of weight lost and therefore acts as a strong driver and predictor of weight regain.14 MacLean referred to this phenomenon as the ‘energy gap’ where ‘more energy is desired than is required.’15 It is reasonable to assume that a method whereby calorie intakes could be increased but fat gain was limited, would allow for the energy gap and hunger to dissipate over time. To put it simply, we believe reverse dieting may help some people maintain their weight loss, by allowing them to consume an increasingly greater amount of food over time, while not adding more body fat than they would like. Something else to consider is that reverse dieting is not just for a ‘post diet’ phase, in fact there are many potential applications. In particular, people who have spent long periods of their life yo-yo dieting may find great benefit from reverse dieting. People who truly have ‘slow’ metabolisms or a relatively ‘low’ total daily energy expenditure due to a sedentary job, may also find value in reverse dieting. Finally, people who would simply like to have the ability to consume more food, gain lean body mass, and limit fat gain to an absolute minimum may also find benefits from reverse dieting. We do want to be clear, as of now there are no scientific studies that use the term ‘reverse dieting’ as of the time we are writing this book. We’ve had discussions with a number of researchers and many are hopeful to carry out studies on this concept in the future, but as of now, no hard data exits. The purpose of this book is to discuss why we think reverse dieting is a useful concept, the mechanisms of how we think it may work, how to implement it successfully, and our own client case studies to support our opinions and hypothesis. 12.

In reality, we do not have a weight loss problem, we have a weight regain problem. As we discussed in the last chapter, weight loss maintenance is incredibly hard to maintain. Less than 20% of people who lose at least 10% of their body weight are able to maintain it for even a single year.1 Some have claimed that diets have a 95% failure rate, and while that may not be completely accurate, the point is maintaining weight loss is incredibly difficult and not the typical experience for most dieters. In fact, of those dieters who regain lost weight, one-third to two-thirds of them will add back MORE weight than they lost in the first place.2 This has led some people to claim that ‘diets don’t work’ or that diets activate ‘starvation mode’, and that dieting causes the metabolic rate to slow down so much that you end up storing fat even on low calories. Don’t worry, ‘starvation mode’ is a complete myth and diets do work insofar as they cause weight loss when caloric expenditure exceeds calories consumed. We’ll talk more on this later if you don’t believe us. So why do many people end up weighing MORE in the post diet period? One thing to keep in mind is that this phenomenon, often referred to as ‘body fat overshooting,’ is typically seen in lean people who attempt weight loss, relative to overweight or obese people, who tend to just return to their previous weight. In fact, research has shown that people who were initially considered ‘normal weight’ when they began trying to lose, had two times the risk of weight regain in a 6-15 year follow up compared to non-dieters.3 Further, in a study examining 1.

We can’t tell you how many potential clients we have missed out on working with because we told them what they needed to hear vs. what they wanted to hear. Weight loss may be hard but keeping the lost weight off is even harder. This is for a multitude of reasons that include physiological, psychological, sociological, and possibly economical reasons. We will cover some of these, but it’s important to point out that the difficulties in losing weight and keeping it off can’t simply be explained by just one thing. There are a multitude of reasons, some more important than others and we need to do our best to combat them all. In fact, Dr. Paul MacLean, a researcher from the University of Denver who has done some of the best work on body fat regain in our opinion, stated in a review paper on this topic, “To be successful in the long term, our strategies for preventing weight regain may need to be just as comprehensive, persistent, and redundant, as the biological adaptations they are attempting to counter.”5 What a powerful statement, and something that is NOT considered by virtually any weight loss diet or diet book out there, except for Fat Loss Forever (yes, shameless plug, but it’s great). Think about it, when was the last time you remember a TV personality, diet doctor, celebrity, diet author, coach, trainer (insert whomever you like promoting a diet) speak about how to maintain what you lost? It’s very rare, mostly because it’s not sexy and doesn’t sell. Most people simply want to know how to get off more weight, but many times that is because they have already been through several cycles of weight loss and regain. 4. (n.d.).

THE PROBLEM WITH WEIGHT LOSS 11 The Physiological Cost of Dieting - Metabolic Adaptation If you’ve been following us for any period of time, you could make a nice drinking game off the number of times we say the words ‘metabolic adaptation’ that would keep you pretty tipsy most of the time. It is with good reason though, metabolic adaptation is an extremely important aspect of dieting that most people neglect to consider. It is also the source of much confusion regarding energy balance or as most people refer to it: calories in vs. calories out (CICO). Many popular social media diet gurus like to make strong statements regarding CICO, mainly claiming that it is outdated and not supported by science, however, nothing could be further from the truth. An entire chapter was dedicated to energy balance in Fat Loss Forever and we don’t want to belabor the point here, but it’s worth doing some recap, especially for those who may have not purchased our previous books/ebooks. Energy balance is what it sounds like, so by saying that energy balance is not valid, is like saying that you don’t believe in gravity. Many people will claim that counting calories doesn’t work because they counted calories and didn’t lose any weight, or that someone did not count their calories and was able to lose weight. That’s like saying gravity isn’t valid because planes can fly. You may count calories and not lose weight, you may also not count calories and still lose weight, but regardless of whether or not you count calories, calories will always count. As much as people would love to believe the contrary, there are no energy negative foods, or foods you can eat as much as you want and still lose weight. “But wait a minute, you’ve both said that even when calories are equated, higher protein and fiber can lead to better fat loss, doesn’t that invalidate CICO?” Good question, and we can understand the confusion. First, you need to understand what energy balance/CICO actually is. It’s quite literally the balance or the difference between the energy you consume and is made available to your body after digestion vs. the amount of energy your body requires on a daily basis. ANY dietary approach that produces weight loss does so by tipping the balance of energy in vs. energy out, either by reducing energy intake (CI), increasing energy out (CO), or both. Protein has been demonstrated to increase energy expenditure when compared to carbohydrate and fat, therefore tipping the THE PROBLEM WITH WEIGHT LOSS 12 scales.6 7 Both protein and dietary fiber may also work by decreasing energy intake and thereby improving energy balance for fat loss on both ends of the scale.8 9 In fact, protein appears to be relatively unique amongst the macronutrients in its ability to enhance energy expenditure. However, when protein and calories are equated between diets, while carbohydrate and fat are varied, there does not appear to be any significant differences in fat loss or energy expenditure even when very extreme diets are used (ketogenic vs very low fat).10 People seem to confuse the perceived simplicity of CICO with the mechanisms of CICO being simple. We’ve had people say things like “I was eating in a calorie deficit and I didn’t lose weight.” No, you weren’t. “But…” Just stop, no you weren’t. You weren’t in a calorie deficit. You may have been eating a level of calories that you thought would cause fat loss or that may be predicted to cause fat loss based on some equations or that should result in fat loss according to an expert, etc. but if you didn’t lose weight, then it wasn’t a deficit. Furthermore, it is important to note that tracking isn’t always perfect either, and there can be up to a 20% error among food labels, which is often cited by anti-CICO people, however this is a bit of a cop out. Encouraging people to NOT track macros because you can’t track it perfectly is silly. As we said, calories count whether you count them or not, so you might as well count them to the best of your abilities, even if it isn’t perfect, it’s better than having no freaking idea. It’s also important to point out that if you aren’t weighing/measuring your food, then you are probably underestimating your calorie intake by a lot. How much? Research shows that people underestimate their calorie intake by anywhere from 18-70%, with 6. “Timing protein intake increases energy expenditure 24 h after ... - NCBI.” https://www.ncbi. nlm.nih.gov/pubmed/19997003.

THE PROBLEM WITH WEIGHT LOSS 13 women more likely to under report than men and obese people more likely to under report than non-obese.11 12 So before you claim that you “ate low calories and didn’t lose weight,” did you really? Did you measure it all out? Did you track all the licks, bites, snacks, chewing gum, swigs of drinks while standing at the fridge, etc? Be honest with yourself, because if you aren’t then you will only have to face the lack of results. Even still, there are people who diligently track their food intake and workouts who still can’t seem to lose weight, even on calorie levels that should facilitate weight loss. So does that mean they have invalidated CICO? No, it simply means that they likely have a low energy expenditure. It’s not ‘starvation mode’ or any other such nonsense. You see, another big reason people fall into the trap of not ‘believing’ in CICO due to ‘simplicity’, is that they also fail to realize that calories in and calories out are not independent variables. Calories in affects calories out significantly. This is where metabolic adaptation comes in. Metabolic adaptation is the adjustment of energy expenditure by the body based on caloric intake (and body mass) to facilitate return to homeostasis. If you eat fewer calories than you burn, you lose weight, but your energy expenditure slows down over time, so that what was originally a deficit eventually becomes your maintenance. Most of you who have done a weight loss diet where you tracked your calories for any decent period of time have likely experienced this. You begin the diet on a certain number of calories and watch the scale drop for a few weeks or even a few months, but eventually you reach a plateau even though you are still eating the same amount of calories. This is because firstly, because your bodyweight has decreased and has a lower energy requirement to move about, secondly, your energy expenditure has decreased from metabolic adaptation. On the same token, if you overfeed your rate of energy expenditure can increase over time. But before we get into the mechanisms of how metabolic adaptation occurs, it’s important that we define what encompasses ‘calories out’ or our total daily energy expenditure (TDEE). Your TDEE consists of 4 basic components: 11. “Assessing dietary intake: Who, what and why of under-reporting. - NCBI.” https://www.ncbi. nlm.nih.gov/pubmed/19094249. Accessed 26 Aug. 2019. 12. “Under-reporting of Energy Intake from 24-hour Dietary Recalls ... - NCBI.” 28 Feb. 2014, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4064631/. Accessed 26 Aug. 2019. THE PROBLEM WITH WEIGHT LOSS 14 1. Basal Metabolic Rate (BMR) 2. Non Exercise Adaptive Thermogenesis (NEAT) and Non Exercise Physical Activity (NEPA) 3. Exercise activity (EA) 4. Thermic Effect of Food (TEF) Basal Metabolic Rate (BMR) — The major component of your TDEE is your basal metabolic rate (BMR). Your BMR accounts for approximately 60% of your TDEE and is the amount of energy your body requires to run basic processes and “keep the lights on,” so to speak. A more simple definition might be our “existence calories.” Still, even though this is a baseline to keep you alive, for most people it’s still the major determinant of your TDEE unless you do a lot of activity, in which case BMR may be a much smaller overall contributor to your daily TDEE. Some commonly used synonyms of BMR are resting metabolic rate (RMR) and resting energy expenditure (REE); however, it’s important to note that these terms have slightly different definitions. Non exercise activity thermogenesis (NEAT) and Non exercise physical activity (NEPA) — NEAT is the amount of energy you spend doing unconscious little movements throughout the day that aren’t actually exercise.These include typing on the keyboard, talking, fidgeting, wiggling your toes, (or, like my lovely wife Holly, swaying side to side when about to attempt a Deadlift PR). NEPA on the other hand, refers to walking, standing, and any voluntary, non-exercise activity. NEAT is actually the most adaptive component of metabolism, and it increases significantly during a caloric surplus and decreases significantly during a deficit, often without realising it. Everyone handles a calorie deficit differently. Sometimes even a small deficit renders you into being as inactive as Jabba the Hutt,(Star Wars character for those of you who live under a rock). So as your NEAT goes down, some people will consciously increase their NEPA to offset the stillness of their metabolic adaptation. Therein lies the difference between NEAT and NEPA: NEAT is involuntary and not as easily modifiable as it happens subconsciously. Case in point, if you decide to do extra steps or a long walk in order to increase your NEAT, then it’s not really NEAT. It’s NEPA, or even planned exercise since you are purposefully going out of your way to do it. THE PROBLEM WITH WEIGHT LOSS 15 NEAT is often used interchangeably with NEPA (non exercise physical activity), though the main difference is whether we are conscious of the activity or not. For our purposes—and in the interest of not nitpicking, we will refer collectively to NEAT and NEPA simply as NEAT. Thermic Effect of Food (TEF) — As weird as it sounds, there is also a thermic effect of food, meaning that it costs you energy to extract energy from the food you eat everyday. Think of it like a combustion engine. The conversion of gasoline to energy isn’t perfect; in fact, a lot of the energy is wasted and your car has to put energy into the system to extract energy from the gasoline. Different foods require varying amounts of energy to be processed and digested. Generally speaking, foods high in fiber and protein have a higher TEF. Carbohydrate and fat have lowerTEF, around 5-15% for carbohydrates and 0-3% for fats, whereas protein and fiber are closer to 20-30%.13 Exercise Activity (EA) - This is exactly what it sounds like. When you exercise, you expend calories. How many you expend depends on the duration and intensity of the exercise performed. So when we get to the point in the book where it’s time to calculate these equations to begin your reverse diet, you have to take all of these into account. If all this looked like an equation, that equation would be: TDEE = BMR + NEAT + EA +TEF Now that may look simple but consider that while BMR and TEF don’t really change from day to day in the short term (so long as you are eating the same calories day in and day out), NEAT and EA on the other hand, are extremely modifiable. Perhaps you work a job where you stand on your feet and walk all day and then on your off day, you tend to sit on the couch and watch TV. This could be a difference of several hundred calories or even over 1000 calories per 13. “Diet induced thermogenesis - NCBI.” 18 Aug. 2004, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC524030/. Accessed 27 Aug. 2019. THE PROBLEM WITH WEIGHT LOSS 16 day depending upon the level of expenditure that job requires. Therefore you could theoretically be eating in a deficit on some days when you are working and in a surplus on days when you aren’t. So were you ‘eating in a deficit and not losing weight’? No. We realize we are probably belaboring the point a bit, but it’s important to understand that while the concept of energy balance is simple, practically pinpointing a specific number from day to day is more difficult to obtain, since the systems that determine how much energy goes into your body and is expended by your body are complex and constantly changing. It’s important to remember that energy balance is not static. Metabolic Adaptation and The Body’s Self Defense System If you thought that energy expenditure was complex before, metabolic adaptation takes it to a whole new level when determining energy balance. Let’s use the example of a car since our bodies similar to a car in many ways (imperfect production of energy from fuel). Your car you bought comes with an approximate fuel efficiency (this is referred to as miles per gallon of fuel or kilometers per liter of fuel if you live in a non-US country). Think of the fuel you put in your car as calories and the gas tank as your body’s adipose (body fat) stores. It’s not a perfect or exact comparison, but practically adipose tissue exists to store energy from food. Unlike a car, we’d want the worst fuel efficiency possible so that we’d burn through our energy stores faster (resulting in loss of body fat). That fuel efficiency (energy expenditure) can change depending upon whether or not you are driving in the city vs. the highway, as well as how fast you drive, how quickly you accelerate, and how often you make a turn. This is why your fuel efficiency sometimes doesn’t match what it ‘should’ be because what goes into determining that fuel efficiency is pretty complex, just like energy expenditure in your body. If we were to add metabolic adaptation into this comparison, imagine that as you started burning through more fuel, your car sensed that and was able to automatically improve its fuel efficiency. Maybe you were getting 20 miles to the gallon when you had a full tank but now that you are on half a tank you are getting 26 miles to the gallon! How great would that be for your car? Unfortunately for us, this means that as we begin losing body fat, our body becomes more efficient at energy production and our energy expenditure goes down significantly. This is accomplished through a multitude of adapta- THE PROBLEM WITH WEIGHT LOSS 17 tions with one major goal: lower your total daily energy expenditure to spare energy so that you don’t starve and die. It’s always important to understand why the body does something from an evolutionary perspective. Becoming obese creates a whole host of health problems, so why in the world would we have evolved to be able to so easily gain fat? Until the last 70 years or so obesity was not an issue, but for the 200,000 or so years prior, starvation was a VERY real threat (in reality even further back than this since our ancestral predecessor species would have faced the same problems). The goal of biology is for an organism to survive long enough so that it can pass on its genetic material. So that’s it, that’s the major goal. If you starve and die, you can’t pass on your genetic material, which is pretty shitty for biology. Thus, the body’s metabolism created an elaborate array of protective tripwires to prevent us from easily being starved. In Fat Loss Forever we referred to it as a 3 pronged self defense system with metabolic adaptation serving as the first prong of the body’s self defense system. DEFEND Metabolic Adaptation RESTORE SELF-DEFENSE SYSTEM Hunger & Fat Storage Efficiency FAMINE PREVENT Number of Fat Cells Figure 2.1: The body’s 3 pronged self-defense system. Prong 1 is the “defend” prong where metabolism slows during caloric restriction to defend against starvation. Prong 2 is the restore prong where hunger exceeds the energy required to restore energy balance and systems that promote fat storage are enhanced while under caloric restriction. Prong 3 is the prevent prong where the body may increase the fat cell number if weight is regained too rapidly in order to defend against future energy deficits. Metabolic adaptation works by reducing the body’s total daily energy expenditure when exposed to an energy deficit (aka diet) through a myriad of adapta- THE PROBLEM WITH WEIGHT LOSS 18 tions that affect nearly every single component of energy expenditure. BMR, NEAT, and to a lesser extent EA are all reduced in response to caloric restriction.14 15 16 Some decrease in BMR, NEAT, and EA are to be expected with weight loss purely due to a lower energy requirement to carry around a reduced body weight in response to dieting. That is, if you are 300 lbs and lose 50 lbs, your body does not require as much energy to carry out daily activity as it did when you were 50 lbs heavier. Interestingly, the reduction in NEAT and BMR are often disproportionate compared to the amount of body weight lost. That is, even when correcting for the loss in total body weight, and we can determine this with some relatively straight forward math, BMR is still reduced compared to pre-diet levels. A typical response appears to be approximately a ~15% reduction in BMR more than would be expected based on the amount of weight one loses.17 Let’s put that in context because that statement in and of itself is a bit nebulous without numbers. If we use equations like the Müller equation, which can predict metabolic rate relatively accurately, and compare them to an individual’s ACTUAL metabolic rate, we can get an idea of metabolic adaptation. We won’t go into too much detail about this equation for now as we will cover it in later chapters. Let’s say that someone begins a diet with a measured BMR of 2043 calories per day and their predicted BMR (they never perfectly align) as calculated by Müller or a similar equation is 2097. After a significant loss of body weight let’s say their predicted BMR using the Muller is now 1877. On average their measured BMR would be closer to 1595 (15% reduction). Keep in mind however, that is just the average looking at the available literature on energy restriction and the adaptive response to dieting. In the cases of more extreme weight loss and caloric restriction, or extreme levels of leanness, it appears that metabolic adaptation responds in propor14. “Metabolic adaptation to weight loss: implications for the athlete - NCBI.” 27 Feb. 2014, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3943438/.

THE PROBLEM WITH WEIGHT LOSS 19 tion. For example, Hall et al. examined participants from TV show ‘The Biggest Loser’ who lost massive amounts of weight (over 100 lbs on average) and found that even SIX YEARS AFTER the show, their BMR (they actually measured their RMR, which is slightly different but for our purposes we will use them interchangeably) was ~500 calories LOWER than what was expected using equations!18 When the participants started the show, their average BMR was measured at 2607 kcal/day while their predicted BMR was 2577 kcal/day. Six years later their measured BMR was 1903 kcal/day while their predicted BMR was 2403 kcal/day, a ~21% difference. This was in spite of the fact that 6 years later most of them had regained quite a bit of weight. This is not the only study showing extreme metabolic adaptation to weight loss however. Russow et al. demonstrated a MASSIVE 35% metabolic adaptation in a male natural bodybuilder who pushed leanness to the extreme.19 This subject began his 24 week diet with a measured BMR of 2424 kcal/day (predicted was 2118, so his BMR was actually faster than what equations predicted), which then plummeted to 1283 kcal/day over 6 months dieting! His predicted BMR at the end of his prep using equations was 1973 kcal/day. This is only one case study, but this is a great example and suggests that while metabolic adaptation may average around ~1015% in most cases, if weight loss or leanness is pushed to the extreme, there may be more extreme adaptations. NEAT appears to respond with an even more robust reduction in response to caloric restriction, with several studies showing up to ~500 kcal per day reduction in energy expenditure attributable from NEAT.20 This may seem pretty extreme and you might not think that your body can slow you down this much, but it’s incredible how powerful these adaptations are.

THE PROBLEM WITH WEIGHT LOSS 20 approached the peak of my leanness, I remember sitting on the couch watching TV and a show was on that I didn’t care for, but the remote was on the other side of the couch. In order to change the channel I would need to get off my position on the couch and grab the remote to change the channel. I elected to watch another 25 minutes of a show I didn’t like just so I didn’t have to get up and retrieve the remote. This is a great example of my body attempting to reduce my energy expenditure by reducing my movement throughout the day. Holly also experienced a similar phenomenon in her recent diet for WBFF Worlds. We have a two story home and she realized she was beginning to carry 4-5 beverages up the stairs to her office, just so she did not have to expend energy going up and down the staircase to stay hydrated throughout the day, lowering her energy expenditure. This wasn’t a conscious decision, it just happened. Caloric restriction and weight loss can also reduce fidgeting, and in my case I started talking less, talking slower, and blinking slower (I’m not kidding about this). Another area of energy expenditure that metabolic adaptation modifies is exercise activity. There are a myriad of studies demonstrating that voluntary exercise decreases under caloric restriction, but what might be even more interesting is that adding more exercise appears to decrease NEAT even further as well.21 22 Talk about confusing! This is probably one of the reasons that exercise alone tends to not have nearly as powerful an impact on reducing body weight as does caloric restriction or exercise combined with caloric restriction.23 Interestingly, when it comes to exercise it appears that resistance training is superior to endurance exercise for fat loss.24 This is likely due to resistance training’s ability to increase lean body mass which would theoretically improve metabolic rate compared to those who don’t resistance train.

THE PROBLEM WITH WEIGHT LOSS 21 the most distressing information regarding metabolic adaptation and exercise is that even when the same amount of exercise is performed, caloric restriction and weight loss reduce the amount of energy needed to perform the same exercises.25 26 Some reduction in exercise energy expenditure should be expected due to decreases in body weight. Since a weight reduced person will have less mass to move during exercise, it makes sense that they will expend less calories. However, even when studies are performed where weight is added in the form of a weight vest to replace the weight that they lost, there is still a lower cost of energy required to complete the exercise, indicating that there is metabolic adaptation to make the body more efficient at exercise under conditions of weight loss.27 You may also be wondering about thermic effect of food since it’s the final piece of the equation we haven’t covered. It appears TEF also decreases during caloric restriction, but only due to eating less total food.28 That is, on a per calorie food eaten basis, TEF does not seem to decrease under conditions of caloric restriction and weight loss. The absolute number of calories burned from TEF however does decrease since less total calories are being consumed. Taken together, these data indicate a robust metabolic adaptation response to weight loss and caloric restriction that acts as the first prong of the body’s self defense system against weight loss/starvation. But how does this happen? What are the underlying physiological mechanisms? To understand that, we must first examine a concept called body fat setpoint. 25. “Contribution of decreased body mass to diminished thermic effect of ....” https://www.ncbi. nlm.nih.gov/pubmed/3235273.

THE PROBLEM WITH WEIGHT LOSS 22 Body Fat Setpoint and Metabolic Adaptation We just finished discussing what happens to your energy expenditure when you diet, but it’s also important to discuss the how and the why. We believe the theory of body fat setpoint in large part explains the ‘why’ of metabolic adaptation and is responsible for directing the how. Before we get into that, let’s discuss the theory of body fat setpoint. This theory postulates that there is a narrow range of native body fat that our bodies like to stay at. If we drop too far below that range, energy expenditure declines and hunger levels increase in an attempt to drive our body’s back into a positive energy balance and put body fat back on. By the same token, if our weight increases too far above our setpoints, energy expenditure increases and hunger decreases in an attempt to bring us back to our norm. If this was the case however, why do people get fat? Shouldn’t our energy expenditure increase with decreasing hunger and drive us back down to our normal? In theory, yes, but there are a few caveats. The first being that these biological controls developed over hundreds of thousands of years, most of which we did not have access to highly energy dense foods. Ever try overeating on meats, fruits, veggies, potatoes, rice, and even just plain bread? It ain’t that easy. But throw in ultra palatable cakes, cookies, chocolates, ice cream, etc and we can blow right past those normal controls since our hunger is not satisfied nearly as much by those hyper palatable foods as they are with whole foods. The other thing to consider is that body fat setpoint likely developed as a biological control in response to risks at both ends of the evolutionary spectrum. If body fat gets too low, we risk running out of energy and starving to death. If body fat gets too high, the risk of predation increases. It’s hard to outrun a lion if you’re carrying around 50 extra lbs of fat. In the last 10,000 years the risk of predation has declined dramatically, far lower than the risk of starvation, which is still a very real threat in some areas of the world and was still a very real threat in civilized countries until a century or two ago. Therefore, it would make sense that the biological controls that prevent body fat from getting too low would be far stronger than those that put the brakes on fat gain. THE PROBLEM WITH WEIGHT LOSS 23 So how do our bodies sense this ‘setpoint.’ It seems to largely be signaled by the size of the individual fat cells rather than total body mass.29 Losses or gains in body fat are typically due to changes in fat cell size while fat cell number appears to be tightly controlled.30 However, there is some evidence that the total number of cells can increase under various conditions, but we will cover that later. The important take home is that under most conditions, fat cell size is basically an indicator for total fat mass, since the total number of fat cells don’t typically change. This loss or gain in fat cell size is believed to be communicated to the brain by a hormone called ‘leptin’ and possibly by a yet unidentified adipose tissue catabolic hormone (this is the hormone that would theoretically control increasing energy expenditure during overfeeding).31 32 Leptin is a hormone secreted by the fat cells (and some other cells) in proportion 1) to their size and 2) to short term energy flux across the fat cell.33 Leptin is involved in many processes in the body but it’s primary role appears to be increasing energy expenditure and decreasing hunger. Leptin is fascinating in its ability to respond to both short and long term energy signals in fat cells. As fat cells shrink, leptin secretion is reduced, thus signaling to the brain a reduced energy state and in response, energy expenditure decreases and the desire for energy intake increases. By the same token, as fat cells expand, leptin secretion increases and signals to the brain that there is an energy surplus, thus increasing energy expenditure and decreasing the desire for energy intake.34 In this way leptin functions much like a thermostat for body 29. “Biology’s response to dieting: the impetus for weight regain. - NCBI - NIH.” https://www. ncbi.nlm.nih.gov/pubmed/21677272.

THE PROBLEM WITH WEIGHT LOSS 24 fat. If you set the thermostat at 70 degrees and the room warms up to 71, the air conditioning kicks in and bumps you back down to 70. If the room cools to 69 degrees, the heater kicks on and bumps it back up to 70. It’s a crude analogy, but leptin works much the same way with energy metabolism and body fat. You might be wondering why drug companies haven’t just synthesized a bunch of leptin shots to cure the obesity epidemic. Leptin, is derived from the greek word leptos, which means thin. When researchers discovered the hormone in 1994, they believed it was the key to curing the obesity epidemic. Indeed, ob/ob mice who have a mutated leptin gene became unbelievably fat. These animals are indistinguishable from normal mice at birth but rapidly gain fat during the course of their life, on average weighing 3x more than a normal mouse. Due to the mutated leptin gene, these animals have no appetite control and are hungry almost constantly. These animals also have lower levels of energy expenditure due to non existent leptin levels and develop type II diabetes along with becoming morbidly obese. When these animals are injected with leptin to match normal levels of leptin in mice, they lose body fat and eventually become normal weight.35 So why the heck aren’t pharmaceutical companies synthesizing this stuff and doctors prescribing it to every obese person out there? Probably because obe35. “Leptin Dose-Response Study in Obese (ob/ob) and Lean (+/?) Mice ....” https://academic. oup.com/endo/article/139/1/8/2986870. Accessed 1 Sep. 2019. THE PROBLEM WITH WEIGHT LOSS 25 sity is not a function of low leptin, in fact obese individuals actually have higher concentrations of circulating leptin than non-obese individuals.36 SAY WHAT? I’m sure you are thinking “ok, so I thought you just said leptin regulated body fat and when it goes up, hunger decreases and energy expenditure increases?” That is correct, but something funny happens in the development of obesity. The leptin receptors become insensitive to leptin, much the same way the insulin receptor in cells become insensitive to insulin during the development of type II diabetes.37 This has been modeled in a strain of mice called db/db mice which lack a leptin receptor. These mice become just as obese as ob/ob mice, but unlike ob/ob mice, injecting leptin does nothing to reduce their body fat levels, and they remain incredibly obese.38 How does leptin exert its effects on hunger and energy expenditure? Much of it occurs through leptin binding through leptin receptors in the arcuate nucleus of the hypothalamus.39 In the presence of leptin, the stimulation of these receptors increases energy expenditure through stimulation of the CNS, cardiovascular system, and brown adipose tissue thermogenesis.40 Leptin also increases the expression of uncoupling proteins through its actions on the sympathetic nervous system (which is mediated by its binding to the leptin receptor in the hypothalamus).41 42 Uncoupling proteins increase energy expenditure by 36. “Correlation between Serum Leptin Levels, Body Mass Index ... - NCBI.” https://www.ncbi. nlm.nih.gov/pmc/articles/PMC3074914/.

Increases and decreases in uncoupling proteins are also thought to mediate in large part the effects of adaptive thermogenesis a significant component of metabolic adaptation.44 So what does this all mean for you, a human who is probably looking to lose body fat or maintain the body fat you lost? It means that leptin is an important regulatory hormone that helps regulate body fat setpoint, however, if you gain enough fat, your body becomes less sensitive to it. As discussed earlier, leptin responds to short and long term energy status signals from adipose. In the short term, leptin secretion is regulated by the energy flux into the fat cell.45 That is, when more glucose and free fatty acids are entering the fat cell vs. leaving it, leptin secretion increases. Leptin secretion is also increased by insulin stimulated glucose metabolism, unsurprisingly.46 Leptin is also stimulated to a lesser extent by fats and proteins (though it’s not clear if this is an acute effect due to increased energy availability or longer term), while fructose does not appear to increase leptin at least in the short term.47 48 In the long term, leptin secretion is regulated by the size of the fat cells. The larger the cells become, the more leptin they secrete, while the smaller they become, the less leptin they se- 43. (2015, February 10).

THE PROBLEM WITH WEIGHT LOSS 27 crete.49 This information has led many people to believe they should consume large ‘cheat days’ or ‘refeeds’ or ‘high days’ during dieting in order to raise leptin, provide temporary restoration of hunger, and improve fat burning. However the research supporting this idea is very much lacking. In fact, the vast majority of the research shows no advantage to high and low days for fat loss, despite the fact that leptin does increase temporarily in response to overfeeding.50 51 It is worth noting that 3 days of carbohydrate refeeding, but not fat refeeding, increased plasma leptin by 28% and energy expenditure by 7%.52 Now before you go out and eat a box of cereal everyday for the purposes of raising your leptin, with the idea that it may offset some of the above mentioned negative changes that occur with dieting, keep in mind that if ones baseline level of energy expenditure is for example 2000 kcals/day, this means that it would only raise their daily energy expenditure by 140 calories, this is not exactly massive, and likely not even enough to offset the extra calories you’ve overfed on. What seems to be more promising are ‘diet breaks’ which are periods of eating at maintenance calories (eating enough calories to maintain your body weight) for periods of around 1-2 weeks. Diet breaks may improve fat loss efficiency and attenuate metabolic adaptation to caloric restriction.53 54 Whether or not this is mediated by increases in leptin has been yet to be determined, but based on the underlying physiology, it is likely that it’s possible. If one were able to significantly increase leptin, but not increase their body weight by eating at 49. “Leptin concentrations and their relation to body fat distribution ... - NCBI.” https://www.ncbi. nlm.nih.gov/pubmed/10598830.

THE PROBLEM WITH WEIGHT LOSS 28 maintenance, it’s possible this may attenuate metabolic slowing and improve subsequent weight loss. When I (Holly here) finished my WBFF world’s contest prep in 2019, my leptin levels were measured at 0.4ng/mL. After 2 weeks of eating at maintenance, my leptin had increased to to 3.4ng/mL despite gaining less than a kilogram of body weight. This is only an n=1 data point and 3.4ng/mL is still below the normal range for leptin in lean females, so I don’t want to overemphasize it, but it’s certainly encouraging. Going into a long drawn out spiel about diet breaks is beyond the scope of this book, but we wanted to mention their use during a diet as it relates to leptin. For more information on diet breaks please see Fat Loss Forever or The Complete Contest Prep Guide.55 So we know that as we restrict calories and lose weight, leptin initially decreases in the short term due to a reduced energy flux across the fat cell, then also decreases in proportion to the loss in body fat over the long term. This leads to increased appetite and decreases in energy expenditure. This functions to drive what was previously a caloric deficit, back to a maintenance level of calories, or if feeding continues, a calorie surplus.

Accessed 1 Sep. 2019. THE PROBLEM WITH WEIGHT LOSS 29 Many of you have experienced this during a diet as a ‘plateau’ where what was once a caloric intake that produced weight loss becomes a maintenance level of calories. Now you understand the why and a bit of ‘the how’,that this occurs. Many people mistake this metabolic adaptation as proof that CICO doesn’t work, but hopefully now you better understand that CICO is accurate, but it’s not a stagnant model. Your ‘CO’ can and does change based on how much you eat. Think of it again like a budget. On average, if someone who was getting paid $5,000 per month gets a huge promotion and jumps to $10,000 per month, are they still going to spend the same amount of money? A few might if they were really focussed on saving, but the majority of us are going to spend more in this situation since we have more financial flexibility. On the same token, if our income got cut in half overnight, we probably aren’t going to spend like we did when we were making double the money. This is a model where were spending is influenced by income, the two variables do not exist independently of each other. CICO works in a very similar manner. If caloric intake is increased, there is less need to be thrifty with calories and your body can afford to waste some. However, if caloric intake is drastically reduced, the body will pull back the reins on ‘spending’ and become much more efficient with energy production once it’s self defense system has been activated. Dieting Prepares Metabolism for Weight Regain Hopefully by this point it’s obvious that dieting causes your body to induce some pretty serious survival responses. Thus far we have only covered the adaptations that decrease energy expenditure, the ‘calories out (CO)’ portion of calories in calories out (CICO). The body’s self defense to energy restriction, however, does not end at reducing energy expenditure, but also extends to affecting the ‘calories in’ portion of CICO. It’s no secret that caloric restriction increases hunger. That probably makes sense to most of us intuitively, but what may be less intuitive is that the increase in hunger due to caloric restriction is not a proportionate response. As with metabolic adaptation, where metabolic rate decreases MORE than predicted in response to dieting, hunger also increases more than expected in response to dieting. MacLean referred to this as “more THE PROBLEM WITH WEIGHT LOSS 30 energy being desired than is required.”56 Various hormones that stimulate hunger and energy intake are increased during caloric restriction including ghrelin, Neuropeptide Y (NPY), and Agouti-related peptide (AgRP).57 58 If that wasn’t bad enough, your body also readies you for gaining fat quickly once you begin overfeeding again. Dieting decreases the thermic effect of overfeeding, meaning that if you have been eating at maintenance or in surplus calories and you ate a calorie dense meal, you would waste a substantial amount of calories as heat. However, if you have been under caloric restriction for a significant amount of time, you would waste significantly less calories in response to a high calorie meal.59 This makes sense from a survival/evolutionary perspective. If you had been enduring a famine when you finally came across a source of calories, you would not want to waste that energy, you would want to be able to capture as much as possible and store it as efficiently as possible. Therefore, it makes sense that the efficiency of refeeding would increase during a period of caloric restriction/famine. In Fat Loss Forever, we referred to these changes in hunger and refeeding efficiency as the ‘restore’ prong of the body’s self defense system that prepares your body for restoring it’s depleted energy reserves. When you diet, your body perceives it as ‘controlled starvation’ and initiates an elaborate cascade of biological responses in an attempt to restore homeostasis and the body’s original setpoint by decreasing energy expenditure (calories out) and increasing hunger (calories in). This works at both ends of the energy balance equation to drive you back towards a positive energy balance. In extreme cases, however, your body may take it a step further in order to protect you against future famine by increasing your body fat setpoint.

THE PROBLEM WITH WEIGHT LOSS 31 previously, losses or gains in body fat are from fat cells shrinking and expanding, while the total number of fat cells remains constant. There is evidence in the post-diet period, however, that it may be possible to increase fat cell number if someone overfeeds rapidly enough.60 PRE-DIET __ POST-DIET __ Fat Cells Shrink EARLY RELAPSE __ Fat Cells Increase In Number RELAPSE TO PRE-DIET WEIGHT __ Fat Cells Grow SURPASSED PRE-DIET WEIGHT __ Fat Cells Grow To Original Size Figure 2.3: Body fat adaptations resulting from excessive eating in the post diet setting. As calories rapidly increase, differentiation of nascent pre-adipocytes into fully formed adipocytes may occur. This increase in fat cell number may cause establishment of a new, higher body fat set point, making it more difficult to lose fat in the future. Figure adapted from MacLean et al. Studies in rodents allowed to eat ad libitum (aka as much as they want) in the post diet period demonstrate that they actually experience fat cell hyperplasia very early in the post diet overfeeding process.61 In fact, the researchers noted the appearance of small adipocytes beginning to form within 24 hours of post diet overfeeding where subjects approximately doubled their caloric intake from diet levels. Before you freak out about this however, remember that it is an animal study, so the applicability to humans is questionable. However, there is some human data which suggest that it is possible to alter fat cell number.62 Further, it is unlikely that the formation of new fat cells occurs that quickly in 60. (n.d.).

So it is plausible to say that for humans, overfeeding would need to take place for much longer time frames for fat cell hyperplasia to occur, however this is just speculation and more research is required to say this indefinitely. When we first examined this research we were quite perplexed. The normal model of fat loss and fat gain had established that changes in fat mass were exclusively due to changes in fat cell size. However, it appears that the immediate post diet state is a unique milieu in which leptin is low, insulin sensitivity in fat cells is extremely high, fat oxidation is very low, and thyroid hormone is low. This unique hormonal and metabolic milieu may allow differentiation of preadipocytes (small, non functional adipocytes) into fully formed adipocytes.63 Still, this seemed quite odd. Based on what we know about body fat set point, it seemed that during weight regain, fat cells that had shrunk during caloric restriction should simply refill back. However, there may be a more survival based reason that this phenomenon occurs. In Fat Loss Forever, we referred to it as the third prong of the body’s self defense system. If we step back for a moment and consider that the primary focus of the body is to restore it’s depleted energy reserves after famine/energy restriction, it could make sense that an influx of a massive amount of calories in a relatively short period of time might trigger the body to create new fat cells to ensure that maximal assimilation of the massive increase in energy intake. That is, your body doesn’t know when it will get another chance to get that kind of massive influx of energy and thus creates new, small fat cells in order to ensure maximal energy deposition. Not only would this ensure maximal energy deposition, but it would also protect against future energy restriction. Recall that body fat setpoint and leptin secretion are primarily controlled by the size of the fat cells. If new fat cells were to be created, this means you could relapse to your previous total body fat mass, but your fat cells would still be smaller individually than they were at the previous fat mass. In this scenario, it is likely that hunger and desire for increased energy intake would not subside 63. (n.d.). The role for adipose tissue in weight regain after weight loss.. Retrieved September 19, 2019, from https://www.ncbi.nlm.nih.gov/pubmed/25614203 THE PROBLEM WITH WEIGHT LOSS 33 until more fat mass had been regained and the individual fat cells were once again at their original set point size, only now the total fat mass would be greater due to an increased number of total cells. This would also make future fat loss theoretically more difficult due to greater hunger and possible decreased energy expenditure from reduced leptin levels. In fact, this is exactly what the researchers observed. The animals continued to regain fat past their previous body fat mass and did not stop regaining fat until the size of their individual fat cells matched their pre-diet size, effectively increasing their body fat setpoint.64 This may, in part, explain the body fat overshooting phenomenon that has been observed in various human studies in non-obese individuals.65 Some of you may have experienced this for yourself after a diet, the idea has been referred to amongst the fitness community as ‘post show rebounding’, where weight regain occurs at an alarming rate, even at the return of what would be considered normal calorie intakes based on mathematical equations. Often this weight regain continues until well beyond that of the start of the diet.. We realize that many of you reading this may very likely be freaking out. Most of us have over eaten drastically at some point in the post diet setting. Did we increase our fat cell number? It’s hard to know. We think it’s unlikely that one day of overeating could cause this, and that is assuming it occurs in humans. What we would likely say is that if you began massively overfeeding immediately post diet, and sustained that for more than a few days and regained a large amount of fat mass within a few weeks, then it may be possible that this occurred. We cannot say for sure because this research is still in its infancy and there is a lot we do not know. What we do know is that eating as much as you want in the immediate post-diet setting is a bad idea and may have drastic implications for fat regain as well as future fat loss. Not only that, but think about how many people yo-yo diet. They lose weight, then regain it quickly and they do this mul64. (n.d.). Biology’s response to dieting: the impetus for ... - NCBI - NIH.

Based on our knowledge of the body’s self defense system, this could result in individuals who have less LBM due to repeated dieting bouts, a reduced BMR, and increased body fat due to rapid weight regain in between bouts of dieting, not to mention possible increases in fat cell number. In fact, there is some evidence in animals and humans that yo-yo dieting (called weight cycling in science circles), increases the difficulty of subsequent weight loss bouts and decreases lean body mass compared to non-weight cyclers.66 67 While the jury is still out on the effects of yo-yo dieting, we would strongly advise against this behavior. Summary Weight loss is possible and achieved by a large number of people each year, but keeping that weight off is incredibly difficult. Most people add back the majority of weight they lost if not more over time. Metabolic adaptation to weight loss makes maintenance of lost weight even more difficult by decreasing energy expenditure and increasing hunger signals to the brain. Therefore, in order to maintain lost weight, it is important to utilize a diet plan that is sustainable, form good habits, and also attempt to develop ways to mitigate the negative effects of metabolic adaptation over time. Further, it’s extremely important to have a post-diet plan that enables you to recover from the diet without excessive fat regain and possible increase in fat cell number. 66. (n.d.).

Maintenance of lost weight is equally as hard if not more difficult. The reasons are multifactorial and include metabolic adaptation and the body’s elaborate self defense system as we have discussed in chapter 2, but there are also psychological and sociological factors why maintenance of lost weight is so difficult. Physiologically, we understand that increased hunger and decreased energy expenditure are attempting to drive us back towards our body fat setpoint and possibly even higher, but there are also psychological and sociological factors that can’t be separated from physiology. For example, when was the last time you went to a social gathering that didn’t involve food? When was the last time you went to hang out with friends that didn’t involve food or drink? When was the last time you invited someone to your house and you didn’t prepare at least some kind of food or offer a snack to your guests? Food is heavily embedded in our culture, our gestalt, which is why it’s hilarious that some people still believe it’s simply an issue of solving physiological hunger. In fact, many ketogenic diet zealots say that a keto diet is the best diet for everyone because it seems to have some satiety promoting benefits. Even if that’s the case (it’s debatable if a ketogenic diet is more satiating than a non-ketogenic high protein, high fiber diet), many people don’t overeat because they are hungry, they eat out of stress and anxiety, feelings of guilt or shame, and most commonly out of boredom, or the need to feel included as a social group setting, as well as a myriad of other reasons. Socio-economic considerations are also important. People who are poor or live in poor urban areas are much more likely to become obese and have less access to high quality foods.1 2 3 Therefore, framing this problem of losing weight and keeping it off purely from a physiological perspective is short sighted. 1.

Is it all doom and gloom? Certainly not, as there are plenty of people who lose a significant amount of weight and keep it off. What can we learn from them? Probably the most important thing is to stop worrying about shit that doesn’t matter. We can’t tell you how many people get obsessed with details that don’t matter, like what a particular diet does to insulin secretion, or growth hormone, or other specific metabolic pathways. I’m not saying these small things don’t matter at all, but focusing on them is a mistake, because you end up missing the big picture. For example, the ketogenic diet is hot right now (2019 for those of you who read this in the future) and there are people who’ve had success with it. The ketogenic diet drastically limits carbohydrate consumption and may improve satiety. This reduces the calorie intake from food and allows people to lose weight. That isn’t a sexy answer to how it works however, so ketogenic diet proponents have focused on the effects on insulin. The claims circulating are wide, but essentially amount to the idea that you cannot lose fat when insulin levels are high and that’s why the ketogenic diet works so well, since by limiting carbohydrate intake, you limit insulin. This sounds logical to many, since insulin’s action on adipose tissue is to reduce fat oxidation and increase fatty acid uptake into fat cells.4 However, a myriad of studies have been performed where calories and protein are equated while fat and carbohydrate are varied, and found no difference in fat loss.5 Further, even a study comparing ketogenic diets to high carb diets with calories equated have shown minimal difference in fat loss (actually slightly favorable towards the high carb group) even though insulin was over 20% greater in the high carb group (as assessed by urinary c-peptide, a surrogate marker for insulin).6 The main takeaway here is that you can lose weight just fine with a ketogenic diet, but you can also lose it just fine eating carbo- 4.

If you enjoy a ketogenic diet, then it’s perfectly fine to use but what if you hated it? I (Holly speaking) personally followed a ketogenic diet for a period of 4 months in late 2016 - 2017, and after just a few weeks, I was missing carbohydrate based foods so much so that I was ready to open up my own restaurant and dessert bar. Sure, it was novel and exciting to begin with and I was able to experiment with new foods and recipe creation, but it was not sustainable. For me, and certainly for many others, the inclusion of a carbohydrate source is far more sustainable long term. In fact, I could not foresee myself being able to commit to a lifetime of adherence to a ketogenic diet. What if attempting to stick to that made your life miserable and even caused you to start binge eating, which happens often? All because you were worried about insulin, which in the grand scheme doesn’t even really make a difference on weight loss based on the research data. This is one of the reasons that diet preference and sustainability matters. The ‘best’ diet doesn’t mean shit if you can’t adhere to it. You need to pick something sustainable for YOU. Sustainability, Adherence, and the TRUTH about ‘Healthy’ Diets A major point that we tried to hammer home in Fat Loss Forever was the message that there is no magic diet. In fact, between various popular diets including low carb, low fat, and several others, no one particular diet produced significantly more weight loss than others.7 What the researchers did note however, was that dietary adherence, regardless of the diet chosen, was the variable most closely linked with successful long term weight loss. Therefore, we can conclude that it is dietary adherence that is the most important factor for producing weight loss. This has also been supported in another long term trial that showed the greatest long term weight loss success in the individuals who were able to best adhere to their dietary strategy, regardless of what that strategy was!8 If that 7.

Some people like a low carb approach, others prefer a low fat approach, others calorie count, and others may use time restricted feeding strategies such as intermittent fasting to create a calorie deficit. The dietary strategy you choose should be driven by what you find the easiest to adhere to and sustain for yourself. This is extremely individual. For me (Holly here), I enjoy using the approach of time restricted feeding, where I typically won’t eat my first meal until after training around noon, then I will have my last meal sometime around 8-10pm. I don’t enjoy exercising with a stomach full of food, and this reduced 8-10 hour feeding window allows me to have larger meals, and thus help me to feel more satisfied, and improve my overall adherence to my macro targets. Layne hates the idea of fasting, in fact for him, this tends to make him ravenously hungry where he actually ends up consuming MORE food during his feeding window than he would have if he’d used a non-time restricted feeding strategy. In this way, time restricted feeding makes perfect sense for me, but less for Layne. To us starting with adherence and sustainability as the most critical factors for dietary success makes sense. However, others have challenged this notion, pointing out that while some of these strategies may produce weight loss, that doesn’t make them healthy. This criticism is normally levied at those who practice flexible dieting. These criticisms usually imply that specific dietary strategies and/or foods have inherent healthy properties that make them superior to other strategies. This is not supported by scientific data however, as several meta-analyses have demonstrated that the vast majority of the health benefits conferred by diets are due to fat loss.9 10 If the vast majority of the health benefits from dieting are simply from fat loss, and adherence is the greatest factor for long term fat loss, then dietary adherence is also likely the most important for producing health improvements.

MAINTAINING LOST WEIGHT 40 Many of them actually developed binge eating over time because as soon as they consumed a ‘bad’ food they would completely fall off the wagon and go nuts eating everything in sight. Not only did their attempt to be perfect keep them from making sustainable progress, but it actually led them to a disordered relationship with food and weight regain if the binging was bad enough. We aren’t saying that you can eat a ton of junk food as long as it hits your calories, because that isn’t really sustainable long term either. We are simply saying that whatever approach you choose, you will need to be able to sustain it for the LONG term if you want to lose weight and keep it off for good. While reverse dieting isn’t necessarily the same thing as weight maintenance, in order to have a successful reverse, you will still need to have the same mindset unless you wish to gain excess body fat during the process. Keeping Off Lost Weight - The Key Factors While specific diets are not associated with improved long term weight loss, there are some factors and behaviors that appear to be key for losing weight and keeping it off for the long term. We discussed these factors in depth in Fat Loss Forever and we don’t want to completely rehash that chapter, but we will provide a summary. As we stated previously, adherence and sustainability are the absolute key. But there are others that appear to make a big difference as well. Cognitive Restraint: This one is simple. In order to lose weight, you must employ some form of restraint. You can’t eat as much as you want, of whatever you want, whenever you want. It simply doesn’t work that way. In order to lose fat and keep it off you must employ some form of cognitive restraint. This can take many forms such as calorie counting (limiting how much you eat), restricting food groups such as in low carb diets, low fat diets, clean eating, paleo (limiting what kinds of foods you eat), or limiting how often you eat as is the case with time restricted feeding (TRF). All of these are forms of cognitive restraint. It’s also possible to combine some of these forms, ie utilizing a low carb diet where you also count calories and time restricted feed. I (Holly speaking), practice all of these forms of restraint. We aren’t saying you should do that, rather just pointing out that it can be done and these strategies aren’t mutually exclusive. You should choose a form of cognitive restraint that feels the least restrictive MAINTAINING LOST WEIGHT 41 for you. In our case flexible dieting was a godsend because it still allowed us to eat the foods we love so long as we controlled the amounts. Other people may not be able to flexible diet as they may find macro tracking too OCD provoking or may have difficulty moderating their intake of energy dense foods. For other people, low carb dieting feels ‘easy.’ Some proponents of TRF have also claimed that diet strategy felt ‘easy’ to them. What is most important is to find out what works best for you! Perhaps now is the time to experiment with a new approach, now that you have learned that the overarching factor for weight loss is adherence to calories. Self-Monitoring: Self-monitoring goes hand in hand with cognitive restraint. Losing fat requires a concerted effort as does maintaining it. Self-monitoring means you need to remain diligent with your cognitive restraint, whether it’s calorie counting, low carb, TRF, or any other form of dietary restraint. Self-monitoring also means continuing to hold yourself accountable. This is a very difficult one for many people. In an era where many people say to throw out the scale or that the scale is meaningless, the scientific data doesn’t support those ideas. In fact, one of the major commonalities amongst people who lose weight and keep it off is that they weigh themselves frequently.11 Now if weighing in every day makes you want to gauge your eyes out and causes you to have an anxiety attack every time you step on the scale, then moderation needs to be used. However, if you are having fear of the scale, it’s also likely that you have been less than adherent to your diet, hence the anxiety. Further, frequent weighing allows for self-correction. Rather than hiding from difficult facts, if you weigh frequently and notice that you are beginning to put weight back on, it is negative reinforcement that you need to modify your behavior if you do not wish to continue to put weight on. Exercise: Exercise is HUGE for weight loss maintenance but probably not for the reasons you think. While exercise does burn calories, this calorie burn effect seems to have a relatively minimal impact on weight loss.12 Even though 11. (2006, July 19).

Since TDEE = BMR + NEAT + TEF + EAT we should expect that increasing exercise calorie expenditure (EAT) would raise our TDEE. However, there is substantial evidence that TDEE is relatively constrained and increases in exercise past a certain point may actually lead to decreases in NEAT.13 While exercise itself appear to produce little to modest weight loss on it’s own, exercise plus dietary restraint appears to be much more effective than dietary restraint on its own.14 This may be due to the ability of exercise to sensitize the brain to satiety signals, as people who are more active actually tend to consume less calories than those who are sedentary.15 16 Further, regular exercise has been demonstrated to lower the body’s body fat setpoint, decrease the expression of lipogenic genes involved in weight regain, and attenuate the increase in fat cell number during massive post diet overfeeding (discussed in the previous chapter).17 18 19 Based on this research it is not surprising that people who lose weight and keep it off successfully, over 70% participate in regular exercise whereas less than 30% of the people who regained lost weight participated in regular exercise.20 13.

Example: someone who focuses on the fact they are hungry now versus the fact that they’d like to lose weight and maintain it in the long term. Additionally, people who have low recency, and can focus on the long term goal, are much less likely to engage in unproductive fad dieting. We can’t tell you how many people end up sacrificing what they want most for what they want right now. This is especially true when it comes to overeating during social situations, as well as people who engage in fad or crash dieting in an attempt to rapidly lose weight. In the end, this reliance on crash dieting only leads them to invariably regain the weight and start the cycle all over again. Few people want to put in the time to diet correctly: slow and steady, focussed on the long term goal. Even less people have the ability to successfully reverse diet if their goal is to lose more fat. We can’t tell you how many people we’ve worked with who DESPERATELY needed to reverse diet, but only lasted a few weeks before giving into the temptation to diet again, seeking ‘fast’ results. We sadly watched them go back down that cycle of crash diet → → overeat → crash diet → overeat… and so on. Remember that everything is a choice. When faced with a decision, make the decision that your future self will thank you for. Structured Programs: Most people do well with some form of structure as opposed to no structure whatsoever. This can take many forms, but when people have confidence in what they are doing and put their trust in a program, it can improve adherence, and positive feelings about their journey. It’s popular to make fun of programs like Jenny Craig, Weight Watchers, Nutrisystem, etc, or even those who hire diet coaches. Heck, almost everyone has access to the internet, shouldn’t we be able to find the answers we are looking for? In theory yes, but people still do much better when they have someone to guide them.

In cases where the ‘support’ is in the form of instruction or criticism, it appears to have no benefit or even a negative effect.26 If you’ve ever had an experience where people try to constantly tell you how to diet or possibly even nit pick your diet, it doesn’t make you feel good. Support in the form of encouragement or positive feedback however, has the opposite effect. Think about it for a bit, what is the most motivational thing you can get? A compliment. “Wow, you are looking great!” When you hear something like that, you are much more likely to keep doing what you’ve been doing. So if you have a lot of nit pickers in your life, maybe it’s time to adjust your social circle. Hang around people who encourage you, or better yet, participate with you in your journey. Nothing is better than a partner to share the emotional and psychological load. 22. (n.d.). Coaching | Biolayne. Retrieved September 25, 2019, from https://www.biolayne.com/ coaching/ 23. (n.d.).

The difference between those who simply lost weight, and those who were able to keep it off, are that those who maintained their weight loss also maintain these behaviors well after the diet ends. In reality, if you don’t want to gain back all the weight, the diet will never be over. You will always need to practice the behaviors that helped you to lose weight if you wish to keep it off. If you go back to the way you were eating prior to weight loss, then you will regain the weight, it’s really that simple. MAINTAINING LOST WEIGHT 46 The Importance of Accountability and Being Honest with Yourself Many of you reading this book probably believe you have slow metabolisms or hormonal issues that cause fat loss or fat loss maintenance to be close to impossible for you. Some of you might, but it’s likely a very small percentage. While there are some situations where people display very low BMRs, they are pretty rare and even people with low thyroid can still lose weight. In fact, the impact of thyroid hormone on weight loss may not be as massive as you would think. In a study examining over 500 people who went on weight loss diets, they found that those with the lowest levels of thyroid hormone lost about 1.5 kg less than those with the highest levels of thyroid hormone (about 4kg vs. 5.5kg).27 Further, even in extreme cases of clinical hypothyroidism, the average reduction in total daily energy expenditure is about 25%, which is definitely significant, as this would mean someone who would normally maintain at 2000 calories per day might only maintain at 1500 calories per day.28 Absolutely, this is a significant difference, but if you listened to some people talk, they would convince you that losing weight is truly impossible if you have thyroid problems or a slow metabolism. It is not impossible, but it is more difficult. However, if you have hypothyroidism, it is diagnosable and treatable with medication to help restore normal thyroid levels and energy expenditure. Those with low BMRs are also pretty rare, in fact obese people tend to have greater BMR than lean people.29 Further, in one study where people identified as ‘weight loss resistant’ it was found they were DRASTICALLY underreporting what they were eating by almost 50% and also over-reported their physical ac- 27. “Thyroid Hormones and Changes in Body Weight ... - NCBI - NIH.” 31 Jan. 2017, https://www. ncbi.nlm.nih.gov/pmc/articles/PMC5461198/.

MAINTAINING LOST WEIGHT 47 tivity by over 50%!30 Let’s think about that for a moment. If they claimed they were eating 1500 calories per day, that meant on average they were consuming around 2250! Combine that with over-estimating activity levels by 50% and it’s no wonder they identified as ‘diet resistant.’ They aren’t alone. The vast majority of people are TERRIBLE at estimating how much they eat and how much activity they engage in. Underreporting ranges from 18-70% depending upon sex and obese vs. lean. Women tend to under-report worse than men and obese under-report worse than lean.31 Here is the part where you need some ‘tough love.’ We know what you are probably thinking, “that’s not me, I am definitely not under-reporting, I’m no liar.” We want to be very clear that we don’t think the majority of these people in the studies are lying about their intakes. They truly believe that the numbers they are reporting are accurate. So why the huge discrepancy? Because people are TERRIBLE at estimating portion sizes. Have you ever weighed out a serving of cereal? How about ice cream or peanut butter? This last one is our favorite. It’s depressing how small the serving sizes are. Most people slap in a few scoops of ice cream and assume that’s probably a serving. In reality it’s probably 3-4! Not only that, but people typically don’t account for all the licks, bites, and snacks throughout the day. That quick handful of nuts you grabbed? 200 calories. That scoop of peanut butter? 250 calories. The pack of gum you chewed today (yes it counts)? 50 calories. That little bite off of a doughnut you stole? 70 calories. That’s 570 calories right there. Then realize that most people are terrible at actually estimating portion sizes or even remembering they consumed it. So is your metabolism really slow? Maybe, but it’s probably more likely that you are not tracking correctly. So before you conclude that your metabolism is slow, try this exercise. Don’t change anything you do with your current diet, just weigh and track every single piece of food that goes into your mouth for a week. This will be really labor intensive at first, though tracking apps make it way easier. You will probably shock yourself at how much you are eating. When we’ve had 30. “Discrepancy between self-reported and actual caloric intake ....” 31 Dec. 1992, https://www. ncbi.nlm.nih.gov/pubmed/1454084.

MAINTAINING LOST WEIGHT 48 clients do this, we’ve routinely had people report eating under 1200 calories, only to find out they were actually close to or over 2000 calories for the day, even though they genuinely believed they were eating 1200 calories. We aren’t saying this in an attempt to make you feel bad or beat you down. In fact, this information should be very liberating to most people. It means that your metabolism probably isn’t as screwed up as you think it is. We don’t want you to think that in order to achieve your physique goals you’ll need to weigh everything you put in your mouth from now until forever, but it is a very useful experience. Weighing and tracking everything over a period of time will actually make you much better at estimating because you’ll actually understand how many calories and macros are in food. This will drastically improve your ability to estimate in the future so that you can maintain your goal physique once you achieve it without the need to weigh out everything. Keep in mind however, the leaner you want your goal physique to be, the more rigid you will likely need to be with tracking. It’s not reasonable to think that you can maintain a shredded physique year round without diligent tracking. There may be a few select individuals who do it, but for the vast majority (over 99.9%) of us mere mortals, it won’t be possible without diligent tracking. This is speaking from a wealth of experience with physique clients (over 2 decades between us). It is possible to maintain a lean physique without having to weigh everything you eat but you will likely still have to be doing some loose tracking in terms of estimating. In the initial post diet phase however, we really recommend that you continue tracking diligently through your maintenance/reverse diet until your calories return to a more sustainable level. Why Maintenance Mindset is Important for Reverse Dieting For those of you who already know a bit about reverse dieting, all this discussion about maintenance of lost weight is probably a bit confusing. Why are we spending so much time discussing maintenance in a reverse dieting book? This is a great question and the answer is because the habits and behaviors that make for successful weight loss maintenance also make for a successful re- MAINTAINING LOST WEIGHT 49 verse diet. Afterall, the goal of a reverse diet is to get your calories up with as minimal fat gain as possible. This means it’s actually MORE important to focus on these behaviors during the reverse diet than it would be if you were just looking to maintain. Maintenance is kind of easy if you keep doing the things that made you successful during the diet. So long as you keep your calories at a maintenance level overall and keep your activity steady, you will maintain your weight. If you want to increase your calories and minimize weight gain however, you will really need to track accurately, be consistent, maintain activity, and do all the little things right. To be clear, a properly executed reverse diet is more difficult in several aspects than a fat loss diet. But a properly executed reverse diet can set you up for much more success in the long run and make your subsequent fat loss phases much more pleasant. 4 50 WHAT IS A REVERSE DIET AND WHO IS IT FOR R everse dieting means different things depending upon who you talk to. We can tell you how we define it: “A dietary goal to increase calories and energy expenditure while limiting unnecessary fat gain.” Now, that can encompass many different kinds of diets and nutritional strategies. For example, someone just finished a show prep and their hormones are in the tank, no sex drive, voracious appetite, and they are at an unsustainable body fat level. Their priority may be to feel better faster and get to a more healthy place (i.e. actually allowing themselves to purposefully put on some body fat so they feel better). This approach to reverse dieting is going to look much different from someone who lost 100 lbs over the past 18 months and is now focussed on keeping the weight off but getting their calories up to a more sustainable level while absolutely minimizing fat regain. Both can benefit from a reverse diet, but their respective reverse diets will likely look quite different. Why Reverse Dieting? As we covered in chapter two, there are a series of redundant mechanisms that facilitate post diet weight regain by reducing energy expenditure and increasing appetite through changes in hormones, nervous system, and adipose tissue adaptations. These metabolic adaptations occur in response to an energy deficit which is unfortunately a requirement for fat loss. The good news however, is that just as metabolism can adapt to reduced calories, it can also adapt in the opposite direction with increased calories. Indeed, a myriad of overfeeding studies demonstrate that when calories are increased above maintenance, energy expenditure significantly increases to a much greater extent than would WHAT IS A REVERSE DIET AND WHO IS IT FOR 51 be predicted by the gain in body mass.1 2 3 The studies examining energy expenditure increases with overfeeding however were not concerned with the rate at which calories were added, they simply overfed the subjects significantly from day one. Most of the tightly controlled overfeeding studies used intakes of greater 40% above maintenance calories, which for someone eating 2000 calories per day at maintenance equates to them eating 2800 calories. Some of the studies overfeed by as much as 75% above maintenance!4 The least aggressive overfeeding study we could find examined feeding 20% above maintenance calories compared with 40% and 60%, and found that those consuming 20% above maintenance calories gained significantly less fat and the same amount of lean body mass as those in the other groups.5 This study was particularly interesting as while it only had six subjects, it was extremely tightly controlled and utilized a metabolic ward where the food provided to the subjects was tightly monitored and the researchers could also closely monitor the subjects energy expenditure. This information not only has implications for gaining muscle, as it appears just throwing a ton of calories on top of an already sufficient surplus is not better for gaining lean body mass, it also provides interesting insights about metabolic adaptation. In fact, increasing 20% of calories above maintenance for 3 weeks significantly increased the participants metabolic rate by approximately 70 kcal per day (2725 to 2796 kcal/d on average). While this doesn’t sound impressive amount when we look at this in isolation, however over a 7 day period this would equate to 470 calories, and in a social situation this would be quite 1. (n.d.).

Further, the participants did not gain significant body fat over the 3 week time period (only 0.08 kg on average fat mass gained and only 0.67 kg total weight gained). They did however, show a significant ‘cost of weight gain.’ By that we mean the amount of calories that were ‘wasted’ in the process of energy deposition due to overfeeding. So it appears at this level of caloric increase, the subjects deposited less than was expected and this was explained by an increase in TDEE, disproportionate to the increase in caloric intake. What’s more, the responses between individuals in the study were quite variable. Two of the six subjects actually lost weight during the 20% overfeeding period, rather than gaining it! Now does this mean energy balance has been debunked and calories in vs. calories out does not apply? No, but what it does mean is that for those two subjects, the increase in energy intake was overcompensated for by an even greater increase in energy expenditure. We want to be clear on this point, when many people hear energy expenditure, they simply think of purposeful exercise, but understand that purposeful exercise is actually only a small amount of your TDEE. Your BMR and NEAT are both very modifiable and for two subjects it appears that their BMR + NEAT increased to a greater extent than even the increase in calories. It’s important to note than when the researchers overfed the subjects by 40% and 60%, they did not see the same overcompensation. In those overfeeding periods, they did see further increases in TDEE, but not nearly enough to offset the massive increase in calories. Now this is only one study, however, it was extremely well designed and tightly controlled and provides insights that support the notion that calories in vs. calories out is not a static equation, it is a moving target and it is possible to shift your TDEE based on not only how many calories you consume, but also the rate at which you increase them. How Did The Idea Start? This concept of the rate of increasing (and decreasing) calories having an impact on TDEE vs. fat gain first came to me (Layne speaking now), as anecdote during coaching. From 2007 to 2013, the majority of my income was from online nutritional coaching with people one on one. During this time, my primary clientele were natural physique competitors who were either prepping for shows or going through their offseasons. Over the years I made some interesting ob- WHAT IS A REVERSE DIET AND WHO IS IT FOR 53 servations regarding increasing calories vs. weight gain. One of the first things I noticed was that people who worked with me during their offseason often would reach plateaus in weight gain that could not be overcome without much larger calorie increases. For example, often I’d just try adding ~100-150 ish calories once someone had stopped gaining weight. Theoretically, this should equate to about a ~1 lb per month gain in weight, but quite often in practice it didn’t. Often people would not gain at all even after several weeks of adding calories slowly. Often I’d have to increase calories by 200-300 and only then would I see a significant jump in weight gain, sometimes more than I anticipated based on the fact that they had not been adding weight on smaller calorie increases. This led me to theorize that perhaps there were ‘thresholds’ for weight loss and weight gain. It’s likely these thresholds are variable from person to person as research has documented that not everyone gains the same amount of weight from the same calorie increases. For example, those who find it difficult to gain weight, and are more resistant to fat gain, tend to add far less weight than the average person in response to calorie increases, due to increases in NEAT and BMR.6 7 Therefore, it is likely that some people can make larger caloric increases than others without significant weight gain. Even if someone was relatively resistant to weight gain however, they still would gain weight if we increased calories aggressively enough, but what I observed was rarely linear weight gain. Often they would plateau for several weeks and then jump up a pound or even several pounds in a week. I always found this quite interesting and it definitely shaped some of my thoughts regarding metabolic thresholds. Another observation I made was in clients who I prepped for shows who were in great shape several weeks before their shows, so we began to add calories back in. I first started doing this circa 2008, with the idea that if we could add calories back in before their show, we could fill them out so they’d look more muscular onstage, while maintaining their leanness. What I observed in many cases absolutely shocked me. Not only did many of these people not gain 6. “The Role of Non-exercise Activity Thermogenesis in ... - NCBI.” 9 Apr. 2018, https://www.ncbi. nlm.nih.gov/books/NBK279077/.

WHAT IS A REVERSE DIET AND WHO IS IT FOR 54 weight, a good portion of them actually began to lose MORE weight and body fat. As someone who doesn’t believe in magic and always looks for a scientific explanation as to why I might observe something, this baffled me. I also found that the clients who I was able to implement this strategy of increasing calories slowly into a show, tended to not regain as much body fat post show as to those whom I really had to be very aggressive with. At the time, I didn’t think a whole lot of it until I started understanding that this concept might be a worthwhile tool for a post-diet setting as well. Until 2013 I never really looked at the weight regain data, but I was starting to notice a trend amongst the clientele I was getting who had been coached by individuals or teams that I would consider less than stellar. More accurately, their coaching was complete and utter dogshit. I was getting hundreds of inquiries, (mostly women) describing horror stories of how they had prepped for a show on ~1000 calorie diets or less, that were not only calorie restricted, but limited them to only a select few foods. This was coupled with up to 10+ hours of cardio per week, on top of resistance training 5-7 days per week. These people were able to lose significant body weight, at least initially, but after their show (or diet) was over, they absolutely blew up. We often refer to this as the post show rebound. Weight regain of 30, 40, 50, 60, and in one extreme case over 80 lbs of weight gain post show, all inside of a 9 month time frame. These weren’t obese people, these were mostly people who were already normal or lean who had dieted down improperly and then absolutely blown out during the post diet period. Interestingly, many of them struggled to lose weight on the same calories that had previously allowed them to lose the weight. Now I’m not so naive to realise that some or most of these individuals were likely making tracking errors, underreporting, and possibly having difficulties with binge eating, as many of them did. However, even amongst my clients who were extremely rigorous with tracking, I still noticed that after having undergone one of these sorts of diets (or even worse, multiple diet cycles), they seemed to really struggle to lose weight due to extremely low energy expenditure. I formed a hypothesis that perhaps the answer was not to continue to try to lose fat, but rather to implement structured, slow, progressive overfeeding, as a means to increase TDEE and get these clients to a better metabolic place so that in WHAT IS A REVERSE DIET AND WHO IS IT FOR 55 future, they may be able to lose fat without having to starve themselves during weight loss attempts. I’m not sure who first coined the term ‘reverse dieting’ but I don’t think it was me. In fact, I didn’t really know what to call it, I just felt that these people needed to get back to a normal level of energy expenditure so that hopefully in the future they could lose fat. It was a tough sell and many people didn’t want anything to do with it. “What do you mean I need to eat more so that I can lose fat in the future, I want to lose fat now.” Lord knows how much potential income I turned down from people who didn’t like what I had to say and wanted results NOW. Remember from the last chapter that the ability to delay gratification is a big part of being able to keep fat off in the long term, and I found that to be true in practice with my clients. Reverse dieting didn’t start off as an idea in my head, nor did I ever figure it would become something that I spoke much about. It just seemed to be a reasonable solution based on my experience in working with clients. As I began to dig into the literature on weight regain further however, what I saw shocked me. As described in chapter 2, weight regain and difficulty losing weight in subsequent diets wasn’t just confined to physique competitors, it was the majority of dieters. I can still recall the day I ‘broke the internet’ as friend and fellow coach John Gorman liked to refer to it, when I released the first video on my youtube channel describing metabolic adaptation, and the problems with dieting and weight regain. I regretfully titled it ‘metabolic damage’ as that was the common term to describe people who were dealing with the ‘symptoms’ of rapid weight regain after a diet and difficulty with subsequent weight loss phases. The response was overwhelming. Within 24 hours I had received over 200 inquiries for coaching from people who were absolutely desperate for help. People said “it was like you described my life.” Others said things such as (paraphrasing), “it’s like you had a camera on me and were describing what happened to me with such accurate detail that it was almost creepy.” I’m sure others in the industry had probably talked about this topic before, but I am not aware of when or where, but that video was the first video to really strike a nerve in the fitness community regarding this topic of metabolic slowing and weight regain. WHAT IS A REVERSE DIET AND WHO IS IT FOR 56 I was already 95% full with clients at the time and was instantly overwhelmed with inquiries, questions, and people who were just completely and utterly desperate for help. I had described their situation, but what was the solution. I felt that reverse dieting could be helpful for a few different populations, of course people who just ended a diet and wanted to maintain as much of their fat loss as possible, as well as people whose energy expenditure was incredibly low from years of chronic yo-yo dieting or even one or two really bad diets. I also did a series of videos on reverse dieting, unfortunately however, I underestimated how easily it was for people to misinterpret, misrepresent, or misunderstand the spoken word. I heard things like “well I’ve already gained weight after a diet so I’m screwed because reverse dieting only works for people who have just finished a diet.” I heard things like “reverse dieting is just adding 50 calories per week.” I also heard and read things that have been completely taken out of context, such as people claiming that you need to reverse diet even after a 2 week mini-cut (you usually don’t unless it was incredibly severe restriction). Other’s claimed that if you had already gained weight and incurred ‘metabolic damage’ that there was nothing you could do and could never lose weight again (NOT TRUE). On an unexpected note, some ‘experts’ said that I claimed that my WHAT IS A REVERSE DIET AND WHO IS IT FOR 57 clients violated the laws of thermodynamics because they lost weight while adding calories, so I must be full of shit. Looking back, I wish I had approached the entire situation with more of a plan and with a more clear cut hypothesis for reverse dieting. I never dreamed it would resonate with so many people and strike such a chord and to be honest, I was still ‘making it up as I went’ in terms of describing what I was observing with my clients who were using this tactic. Who Is a Reverse Diet For? In an ideal world, you would run a fat loss phase until you reached the desired amount of fat loss, and then maintain it indefinitely, but sadly this is not how things go for most of us. Even if you are able to achieve the desired amount of fat loss, often by the end of that diet phase, your energy expenditure is very low and as such, your calories are often too low to sustain. If you were able to lose the desired amount of fat and you were still eating an amount of calories you could maintain indefinitely, then things are very easy, just maintain that intake and your current activity levels and you should be able to maintain your goal body fat. For most people however, this is not how things typically go, since energy expenditure declines significantly during a fat loss phase as described in chapter 2. Thus, many people would love to be able to maintain their fat loss results while also increasing their energy expenditure and calorie intake back to a more maintainable level. This leads us to the first population of individuals that we feel reverse dieting is applicable for. Population 1: Fat loss goal achieved, but calories are below a sustainable level For these people, the focus will be on increasing calorie intake up to a level they feel is sustainable, while minimizing body fat regain. Most people in this category, like me (Holly here again), will likely want to do a conservative reverse diet and add calories slowly since they are absolutely looking to maintain as much of the weight loss as possible. They will also need to remain incredibly diligent with the methods and habits that they employed during the weight loss phase in order to maintain that weight loss while increasing their calories. WHAT IS A REVERSE DIET AND WHO IS IT FOR 58 Population 2: Fat loss goal achieved during contest prep or extreme diet, recovery required Not everyone diets to a sustainable level of body fat. In the case of physique competitors, combat athletes, and other sports that require very low levels of body fat, the level of body fat that is achieved may not be sustainable and the calories certainly won’t be. This is probably not a popular statement, but most of the people you see in the ‘fitness’ magazines don’t look like that year round. In fact, most of them take all of their professional photos during a very short timeframe while their physique is at its peak. Many of them are not even very ‘fit’ or ‘healthy’ in point of fact due to the toll their extreme diet will have taken on their hormones. In natural bodybuilding case studies, nearly every single male is hypogonadal (clinically low testosterone levels) and many females, (myself included) deal with amenorrhea (loss of menstrual cycle) once body fat levels dip below a certain set point.8 9 10 11 12 13 In order to recover from this beatdown on their metabolism, they will NEED to increase their body fat levels to a healthier, more sustainable level of body fat in order to recover their hormones, metabolic rate, and feel normal again. That doesn’t mean that they need to add excessive amounts of fat just for the sake of ‘recovery,’ but some fat regain will be expected. These individuals will likely need to start out with a more aggressive reverse diet which can be tapered to a more conservative reverse once their body fat has returned to healthy levels.

Population 3: Fat loss goal not achieved but calories are unsustainably low This is a tough group to work with and sadly encompasses the vast majority of the clientele we have worked with. Typically, these individuals have endured multiple improper diet cycles, where they drastically restrict calories in order to lose body fat, which is followed by quickly regaining much of what they lost within a short period of time. Many times these people continue this vicious cycle of yo-yo dieting, where they lose and regain the same 10 lbs over and over again for YEARS. For some the weight range is even greater, and sadly this is the worst possible way that one can diet. Every time you diet and create an energy deficit, you activate the body’s self defense system (described in chapter 2). The more often you activate this system, the stronger it defends. People think regaining the weight they lost is the problem, but that’s not necessarily the case. If they regain it over a long period of time, where their metabolic rate has a chance to recover, then they should be able to lose the weight they lost again (hopefully more permanently this time). However, if they regain it too quickly and do not give their metabolic rate sufficient time to recover before dieting again, their future weight loss efforts are going to be much more difficult. This is supported by a highly controlled study (albeit in rats) which demonstrated that yo-yo dieting lowered metabolic rate and made each subsequent weight loss attempt SIGNIFICANTLY more difficult and also made each post diet weight regain more severe.14 Now you might say ‘well that’s just in rats’ but there is also human data to show negative health outcomes with yo-yo dieting, including reduced lean body mass, often caused by extreme approaches to weight loss, in addition to decreased strength, and increased risk of developing sarcopenia (muscle wasting).15 Since lean body 14.

It’s important to consider that some of these individuals who claim to be eating very low calories and not losing weight are also likely underreporting their caloric intake. As we discussed in chapter 3, the majority of people, as much as we hate to admit this, underreport their food intake, and overweight people frequently underreport more than non overweight individuals. So before you claim that you are eating low calories and not losing weight, be sure that you really are. We aren’t saying this to be mean or to upset you, we simply want you to make sure you are truly tracking everything you eat before you claim that you simply can’t lose weight even on low calories. That means every lick, every bite, everything that goes in your mouth including alcohol, which many people don’t take the time to track and is very calorie dense (7 kcal/gram), it all must be tracked. Many people also eat low calories during the week, but then don’t track on the weekends and eat well above their normal intakes (2500-4000 calories) and wonder why they aren’t losing weight. So before you plant yourself in the category of ‘eating low calories but not losing weight’ BE HONEST with yourself and BE ACCOUNTABLE with what you are really taking in. For people who truly are eating low calories and not losing weight due to decreased energy expenditure, it’s not the end of the road, but the road ahead is going to be pretty long. Since you aren’t at the body fat that you desire, it means we need to reverse diet with the goal of minimizing fat gain, while increasing energy expenditure so that in the future you will be able to lose body fat more effectively at a more reasonable calorie intake. This type of reverse dieting is a very difficult ‘sell’ to people who haven’t achieved their goal body fat. People who get locked in to chronic dieting mentality find it difficult to break loose from their diet mindset. It’s almost as if they only feel comfortable if they are dieting. The idea of purposefully overfeeding to increase energy expenditure to help restore their metabolic rate seems great in theory, but also very difficult for them in practice since they aren’t dieting seeing the scale go down and relatively quick physical changes. As we have said to many clients in the past, WHAT IS A REVERSE DIET AND WHO IS IT FOR 61 “if you continue to do what you have always done, you will continue to get what you have always gotten. If you want a different result, you need to try a different approach.” As our friend Sohee Lee says, “you can’t diet your way out of a bad metabolism.” This is advice many of you probably don’t want to hear, but NEED to hear. If you are happy to diet on very low calories in order to make fat loss progress, then reverse dieting might not be for you, but we have yet to meet one person who is ‘happy’ dieting on low calories. Low calories are typically not very sustainable either, so what invariably happens is that these people are able to stick to low calories for a certain period of time, but often end up drastically over consuming calories on weekends, holidays, or at special events and end up back to square one in terms of their progress. If your energy expenditure is low from chronic dieting and you find that you have difficulty sustaining a calorie deficit due to how restrictive your calories are, then a reverse diet is likely one of your best options. Population 4: No immediate fat loss goal, simply want to increase ‘metabolic capacity.’ I.e. prepare for a more successful future diet, perform better or simply be able to eat more calories. ‘Metabolic capacity’ is a term that I (Layne speaking now), loosely coined years ago to describe increases in energy expenditure with sustained overfeeding. This was something I looked to utilize in my ‘offseason’ clients to increase their energy expenditure so that when they began dieting they would have a greater caloric cushion to cut back down from. For these individuals, the goal was typically increasing muscle mass while getting calories up as high as possible without putting on excessive body fat. These individuals may choose to do any different type of reverse diet, from conservative to aggressive depending upon their tolerance for gaining body fat, as well as how quickly they want to increase their energy expenditure. The idea is that if we take 2 theoretical identical people and one is able to maintain their body weight on 2000 calories per day, but the other is able to maintain their calories on 2500 per day, in theory, the person on 2500 calories per day should have an easier time losing fat the next time they diet, as they have a greater ‘calorie cushion’ to create a deficit from. The person who maintains their body weight on 2000 per day only needs to hit a few plateaus in their fat loss journey before they are staring down 1200 WHAT IS A REVERSE DIET AND WHO IS IT FOR 62 calories per day as their only option for making more progress, whereas the person starting with a maintenance of 2500 calories per day has quite a bit of room to bust through a few plateaus while dieting. Fat loss plateaus are normal and something that you MUST account for when setting up your diet. As we discussed in chapter 2, metabolic adaptation is going to happen. There are various ‘tricks’ and techniques you can use to try to mitigate metabolic adaptation like employing diet breaks, refeeds, wearing weighted vests, and a host of other ‘tricks’, but no matter what you do, there will be metabolic adaptation and you will have to plan for fat loss plateaus. Many people can be dedicated for short bursts of time, but few people can be dedicated for extended periods of time. What ends up happening to many individuals is they are very dedicated to a fat loss phase, but once it ends they stop caring and they regain the weight without first optimizing their metabolic rate. Ideally, most people would not want to regain all the weight they lost, unless they had a goal of building as much muscle as possible. If they did regain all the weight however, the next best thing would be to do so in a way that maximizes their metabolic rate and energy expenditure so that when they diet in the future, the subsequent fat loss phases will be less difficult due to an enhanced energy expenditure. Now we don’t want to oversell reverse dieting. If you are maintaining your body weight on 1800 calories per day, it’s highly unlikely that you can reverse diet yourself to a new maintenance level of 4000 calories per day, there are definitely limits. In fact, some people don’t get huge improvements in their energy expenditure, while others see very large increases from reverse dieting. However, it’s still better than entering ‘fuck it mode’ post diet and regaining all the weight (if not more) while having no regard for improving your metabolic rate or building muscle. We realise that not everyone has the burning desires to become an ‘aesthetics brah’ or achieve a fitness celebrity physique, but perhaps they are more interested in being able to increase caloric intake for the potential performance benefits. Others may simply like to be able to consume a greater amount of calories to facilitate their social preferences and allow for greater food flexibility rather than always feeling like you have to miss out. WHAT IS A REVERSE DIET AND WHO IS IT FOR 63 The reverse diet can absolutely be used for these two populations to drive exercise performance and make for a more enjoyable lifestyle. Population 5: Ended fat loss phase, goal may or may not have been achieved but now focussed on building muscle. One of the most popular questions we get asked is “can I build muscle while reverse dieting.” ABSOLUTELY. In fact, a conservative reverse dieting is almost the perfect ‘lean gaining phase.’ There is very little difference between reverse dieting and ‘gaining’ or ‘bulking’ from the perspective of they all involve overfeeding. The difference is in the rate of overfeeding and that in reverse dieting we are dealing with an ‘allowable weight gain’ vs. an ‘expected weight gain’ when talking about a bulking or gaining phase. We will discuss what we mean by this later, but essentially in a gaining phase you expect to gain weight and if you don’t gain weight, you keep increasing calories until you do, whereas in a reverse diet we aren’t purposefully trying to gain weight, and in some cases if we do, and if the weight regain is greater than what was ‘allowed’ based on the parameters we set, we will make adjustments (more on this later). This population will be similar to the previous insofar as they could choose from any number of styles of reverse dieting depending upon how fast they want to increase their calories, and their tolerance for body fat gain. Summary There are many potential populations that can benefit from reverse dieting depending upon their long term goals, tolerance for fat gain, and individual metabolism. It’s important to emphasize that reverse dieting is not one particular diet or rate of increasing calories. It can encompass a range of different approaches depending upon the individual and their goals. 5 64 HOW TO SET UP A REVERSE DIET: CALORIES N ow that we’ve covered the background on reverse dieting, why it is helpful, and who it’s for, it’s time to dive into the nuts and bolts of setting one up starting with how many calories you need. As we discussed in chapter 4, there are many potential populations who may benefit from reverse dieting and the term reverse dieting covers a range of nutritional strategies. So where in the hell do we start figuring out how many calories to start a reverse diet with? No matter what type of reverse you choose and what your goals are, we need to first determine your total daily energy expenditure (TDEE) so we know what your maintenance calories are. We will use TDEE and maintenance calories interchangeably, they aren’t truly the exact same thing, but they will be the same number. TDEE is the total number of calories that you expend in a day. Maintenance calories is the amount of calories you need to consume to maintain your body weight. Since maintenance calories will be equal to your TDEE, they will both be the same number. So how do we go about determining this number? There are a few different methods that can range from relatively simple to pretty complex, depending upon how exact you would like to be when narrowing down that number. We tend to err on the side of simple, only because it’s unlikely you’ll be off by an incredibly huge amount and even if you are off by quite a bit, we will be giving you instructions on how to adjust your dietary intakes as you go depending upon how your body responds. So even if you underestimated your TDEE and your calories were too low, you’d see your weight dropping and we could increase calories to compensate. Likewise, if you overestimated your TDEE your weight would increase and you can adjust calories back down in response to that. These are only going to help you set a starting point for your reverse diet, so try not to get too obsessed with them. That said, we will show you different methodologies to determine your TDEE starting with the most simple and progressively moving to the most complicated (albeit likely a bit more accurate). With any of these formulas, the first step is to determine our approximate BMR. Then we can apply activity factors to account for things like NEAT and exercise activity (EAT). HOW TO SET UP A REVERSE DIET: CALORIES 65 Now most of these formulas will require you to know your lean body mass and in order to know your lean body mass, you need to have your body fat assessed. There are a multitude of ways to assess body fat, some are more accurate than others, but please understand that none of them are truly 100% accurate. They all make various assumptions and use mathematical estimations in order to determine total body fat levels. We personally like calipers because you are measuring what you actually care about, which is the thickness of the skin. Dual-Energy X-Ray Absorptiometry (DXA) is considered the gold standard in research, but it’s not without drawbacks. The first being that it’s difficult to get access to if you aren’t involved in a university study or unless you’d like to pay a hefty amount of money for a single scan (around $125 in the US). It’s also not something that you can likely use often either, which makes it impractical to use to assess progress as well. People treat DXA like the word of god, but in fact DXA can be easily manipulated or inaccurate as it is a 2 compartment model, by that we mean it shows tissue as being either fat or lean, and lean tissues account for more than just our skeletal muscle mass. Lean tissue includes organ mass, hair, skin, nails and bone mass, as well as water, and water is very easily influenced, dependent on a number of variables. If you eat a lot of food and drink a lot of water before a DXA scan, guess what it registers as? Lean body mass. So you could get a DXA, then go back in 5 minutes later after chugging a jug of water and the DXA will measure you as having miraculously gained a bunch of new lean body mass. Did you really add new muscle tissue? Hell no. Further, if you performed a vigorous workout the morning of or the day before the scan, or you simply consumed a heavily salted meal the night before your DXA, you may also experience changes to your total body water. So you could see that unless you were taking a DXA under the exact same conditions each time you do it, you could have very significant fluctuations in lean body mass based on how much water you’ve drank and food you’ve eaten. In this case you are much better off doing calipers since you can do them in the comfort of your home and take your measurements the same way every time: fasted from food and fluid, in the morning, right after you’ve weighed in. There are also methods like underwater weighing which is fairly accurate, but this method suffers the same accessibility and cost pitfalls as the DXA. There are handheld devices which are convenient for home use but probably a bit less accurate than cali- HOW TO SET UP A REVERSE DIET: CALORIES 66 pers in our opinion. That said, they are completely suitable if you are pressed for time and want something easy that you know you’ll use. Even if they are slightly inaccurate, it’s likely that the relative change in body composition, or measurement to measurement accuracy is still pretty good. Meaning, if someone measures at 17% body fat but they are actually 14%, and they drop 3% body fat on the handheld device, it’s likely they did indeed lose some fat. You may not have exactly the right number, but that’s less important than the relative progress. The most important thing is to pick ONE method of assessing your body fat and then ALWAYS do it the same way every time you do it. With that out of the way, let’s discuss the various methods of determining BMR, the largest component of TDEE starting with the most simple formula and moving to the most complicated (but likely most accurate) way to do it. Most simple: Aragon Formula: Multiply lean body mass in kg (LBM) by a factor of 25.3. Example 1: 25 year old male, 80kg total body weight (TBW) and 15% body fat. Works a job that requires him to stand or walk most of the day and also very intense daily resistance exercise So if you are 80 kg male at 15% body fat, that equals 68 kg LBM. 80 kg x .15 = 12 kg fat mass (FM). LBM = TBW - FM. 80 kg TBW - 12 kg FM = 68 kg LBM. BMR = 68kg x 25.3 = 1720.4 kcal/day (round it to 1720 kcal/day) Example 2: 30 year old female, 70kg TBW and 16% body fat. Has a job that requires some standing and walking and also exercises regularly at a moderate intensity 3-4 days per week. FM = 70kg x 0.16 = 11.2kg; LBM = 70kg - 11.2kg = 58.8kg BMR = 58.8kg x 25.3 = 1487.8 kcal/day (round to 1488 kcal/day) Now we have to apply activity factors (AF) to BMR in order to determine TDEE. HOW TO SET UP A REVERSE DIET: CALORIES 67 In traditional equations, they apply one activity factor, but we find it’s more accurate to use 2 factors: A lifestyle factor and an exercise factor. This basically accounts for NEAT & EAT. So the equation to determine TDEE will look like TDEE = BMR x AF Lifestyle Factor 0.6 - Sedentary (desk job, very little standing or walking needed during the day) 0.7 - Light Activity (some standing and walking during day to day activities and job) 0.8 - Moderate Activity (You spend a good portion of the day on your feet during your job and activities) 0.9 - High Activity (You spend virtually all day on your feet and rarely sit down) 1.0 - Extreme Activity (You work a heavy labor job) Exercise Factor 0.55 - Sedentary (You don’t exercise) 0.65 - Light Exercise (You do some walking and aerobic activity a few days per week) 0.75 - Moderate Exercise (You do multiple days per week of exercise, some resistance training) 0.85 - Intense Exercise (You TRAIN HARD at least 5 days per week) 0.95 - Extreme Exercise (You train intensely over 2 hours per day, virtually every day) Select the activity factor that best describes your lifestyle and then the activity factor that best describes your exercise routine. Add them together to get your overall activity factor. For Layne and I, we both work a sedentary job, so we would select 0.6, although Layne might select a 0.7 since he tends to run around chasing the kids a lot more than I do. Then our exercise is very intense, HOW TO SET UP A REVERSE DIET: CALORIES 68 so we would probably select a 0.85. That puts me at a 1.45 activity factor and Layne at a 1.55 activity factor. You then multiply your BMR by that activity factor. So if we take first example and assume their lifestyle factor is 0.8 (moderate) and an exercise factor of 0.85 since they train hard. We then add 0.8 + 0.85 = 1.65, we would then multiply their calculated BMR of 1720 by 1.65. 1720 kcal x 1.65 = 2838 kcal TDEE (estimated). If we examine our second example we would likely choose a lifestyle factor of 0.7 since the example females job requires some standing and walking and exercise factor of 0.75. This yields an overall activity factor of 1.45. We then multiply her BMR of 1488 x 1.45 = 2157.6 2nd Most Simple: The Müller Equation For our second calculation, we come to the Müller equation. Müller et al. noted the flaws of the World Health Organization’s calorimetry, and they came up with their own calculations based on a homogenous modern population. In this one, we have a few more variables to take into account. We have age and LBM again, but we also have to account for fat mass (FM), and biological sex, which is represented by a 0 if you’re a woman, or a 1 if you’re a man. This equation is our preferred option because it accounts for most of the variables that have the biggest impact on metabolic rate (LBM, FM, Sex, and Age).So all that yields the following equation: (13.587 x LBM) + (9.613 x FM) + (198 x Sex) – (3.351 x Age) + 674 = BMR For our above examples. We would plug in the numbers as follows: Example 1: (13.587 x 68) + (9.613 x 12) + (198 x 1) - (3.351 x 25) + 674 = 1827.5 (Round to 1828 kcal) TDEE = 1828 x 1.65 = 3016.2 kcal (round down to 3016 kcal) HOW TO SET UP A REVERSE DIET: CALORIES 69 Example 2: (13.587 x 58.8) + (9.613 x 11.2) + (198 x 0) - (3.351 x 30) + 674 = 1480.1 (round down to 1480 kcal) TDEE = 1480 x 1.45 = 2146 kcal. As you can see there isn’t a ton of difference between the two equations. The major difference is that male TDEE will probably work out a bit higher when using the Müller equation since it gives an extra 198 calories to men. For females as you can see the numbers are pretty close. However, for older women the Müller will probably work out to be slightly lower. Here is the important thing to remember, these are just ESTIMATES. It is very likely that they will not nail your maintenance calories dead on, but they will probably get you pretty close in most cases and in nearly all cases get you in the ballpark. We can tell you that most people put WAY too much emphasis on finding their ‘perfect’ maintenance calories. We see people stress so much over this. DON’T. Do your best but even if you are off, this book will teach you how to adjust your macros and calories accordingly so that within a couple of weeks of starting, you will be able to self correct back into the appropriate value if you practice what we discuss in this book. The Problem with TDEE Estimate Equations As we emphasized previously, these calculations of BMR and TDEE are ESTIMATES. It is important to point out however, that the population reading this book may be more likely to fall outside of the normal calculations. Dieting, especially prolonged dieting, or yo-yo dieting, reduces TDEE significantly as we discussed earlier in Chapter 2. The average reduction in BMR from prolonged dieting is usually around ~15%. So how can we apply this knowledge? We tend to look at this from more of a holistic, dieting history perspective. If you don’t spend much time dieting or rarely diet, then there’s no need to apply any adjustment. If you do have a dieting history then it can be useful to apply some metabolic factors to your calculations. If you spent over a third of the year in a caloric deficit, then we would recommend reducing the BMR calculation by 5%. If you spend over half of the year in a caloric deficit, reduce the BMR calculation by 10%. If you spend over 2/3 of the year in a caloric deficit, reduce the BMR calculation by 15%. If you are a perpetual yo-yo dieter then reduce the BMR calculation by 20%. HOW TO SET UP A REVERSE DIET: CALORIES 70 If we look back at our examples. Let’s say example 1 (using the Müller equation) had carried out a 12 week diet this year, we might apply a 5% reduction to his BMR. If we use the Müller BMR calculation of 1828 kcal, reducing that by 5% would be 1828 kcal x 0.05 = 91.4 kcal (round to 91). 1828 kcal - 91 kcal = 1737 kcal. TDEE = 1737 kcal x AF 1.65 = 2866.1 kcal (round to 2866). For example 2, let’s go the opposite direction and assume she has been a long term dieter and spends a fair portion of the year in a deficit. If we apply a 15% reduction to her Müller calculated BMR, we get: 1480 kcal x 0.15 = 222 kcal. BMR = 1480 kcal 222 kcal = 1258 kcal. TDEE = 1258 kcal x 1.45 = 1824.1 kcal (round to 1824 kcal). Most Accurate and Complicated Way of Calculating TDEE The most accurate way to calculate your TDEE is to monitor your weight and your calorie intake over time. If we know those two parameters, we can come up with a very accurate assessment of your TDEE/maintenance calories. Since tissue weight has a caloric value associated with it, we can monitor weight changes and determine what kind of calorie deficit/surplus an individual is in. We want to be clear here, you need to examine your weight change across the most recent 2-4 week period of time and when we say weight change, we mean your average weekly weight. That is, we recommend weighing in daily every day for 2 - 4 weeks and then taking the average of each week’s weight to determine your average, then compare those averages against each other compared to the caloric intake. In our previous books we went through in painstaking detail how to calculate what calorie amount is associated with weight loss. We won’t beat those to death, but if you want to learn how we came to those calculations, you can find them in Fat Loss Forever or The Complete Contest Prep Guide.1 Briefly, let’s examine the estimated calorie content of 1kg of FM and 1kg of LBM: Adipose tissue/Fat Mass (FM) is 87% lipid/fat. Therefore 1000g x 0.87 = 870g fat. Fat = 9 kcal/g. FM = 870g x 9 kcal/g = 7830 kcal per 1kg FM. This could also be expressed as 7.83 kcal/g of FM. 1. “Books and Ebooks – BioLayne Store.” https://biolaynestore.com/collections/accessories. Accessed 27 Oct. 2019. HOW TO SET UP A REVERSE DIET: CALORIES 71 LBM is approximately 70% fluid and non-caloric. The remaining 30% of tissue is mostly protein in nature. Therefore, 1 kg of LBM = 1000g x 0.30 = 300g lean tissue/protein. Protein = 4 kcal/g. LBM = 300g x 4 kcal/g = 1200 kcal per 1kg of LBM. This could also be expressed as 1.2 kcal/g of LBM. Knowing this, if we have weight, and specifically body fat measures, we can determine how many calories are associated with fat loss or fat gain. For example, let’s say someone takes their weight every day while they are on the last 4 weeks (28 days) of their diet. During this time they lose 3 kg of weight going from 80 kg to 77 kg. Over that period of time their body fat percentage drops from 16% to 14% body fat. This means that at 80 kg their total mass was comprised of FM 80 kg x 0.16 = 12.8 kg. LBM = 80 kg - 12.8 kg = 67.2 kg. At 77 kg their new total mass was comprised of FM 77 kg x 0.14 = 10.8 kg. LBM = 77 kg - 10.8 kg = 66.2 kg. Therefore, the total FM lost during this time frame was 12.8 kg - 10.8 kg = 2.0 kg. Total LBM lost was 67.2 - 66.2 = 1 kg. Since FM is approximately 7830 kcal/kg, (from the first equation), the calories from FM are 2.0 kg x 7830 kcal/kg = 15660 kcal. Since LBM is approximately 1200 kcal/kg (from the first equation), the calories from LBM are 1kg x 1200 kcal/kg = 1200 kcal. In order to determine the total calories lost over that period of time simply add FM + LBM = 15660 kcal + 1200 kcal = 16860 kcal. This is the TOTAL calorie deficit over that period of time. As we stated previously, this was lost over 4 weeks or 28 days. In order to determine what the average daily caloric deficit was, we can divide 16860 kcal ÷ 28 days = 602.1 kcal/day. If we assume this person’s average daily caloric intake during this time was 1700 kcal/day, we can find their approximate maintenance calories/TDEE by adding HOW TO SET UP A REVERSE DIET: CALORIES 72 their deficit calories to their intake. So in this case TDEE/maintenance calories = 1700 + 602.1 = 2302.1 kcal/day. What if you didn’t lose weight? What if you gained weight? Let’s take the previous scenario and say that they actually overate during that time by 7000 kcals based on their weight increase?. In that case, 7000 kcal/28 days = 250 kcal surplus per day. If they were consuming 1700 kcal per day we would SUBTRACT 250 kcal from 1700 kcal - 250 kcal = 1450 kcal/day = TDEE/Maintenance Calories This way of tracking body fat, body weight, and calories is the most accurate way of determining maintenance calories, but it also requires quite a bit of math. I (Holly speaking) have a short 5 minute video on Youtube that illustrates this exact equation if you are requiring some additional assistance. If you have the data already, then it’s probably not a big deal as the math isn’t crazy difficult. But if you are wanting to get started on a goal, don’t feel like you need to take 4 weeks of diligent tracking before you can get started on your reverse, as we stated previously, the estimations we provided in the first section will get you in the ballpark. HOW TO SET UP A REVERSE DIET: CALORIES 73 On the other hand, perhaps you’ve gotten a bit lucky and you’ve been tracking your intake for a while and also maintaining your weight, that makes it very easy! You are currently eating your maintenance calories… no math required! Where Should I Start My Reverse Diet Calories? As we discussed in Chapter 4, there are several different populations of people that could benefit from reverse dieting. Where you start calorie wise will depend on your specific goals and your tolerance for fat gain. Regardless of the population you belong to and your goals, we at minimum recommend starting your reverse at your current maintenance calories. Notice we said CURRENT. As we discussed, if you have been dieting for a while, your post diet maintenance calories will be significantly different from the calories you began your diet on. Before the diet began, your maintenance calories might have been 2100, but after a few months of dieting it could be closer to 1800-1900. You want to be sure you use the CURRENT maintenance as your starting point rather than your pre-diet maintenance. Now that said, we will discuss a few different methods of reverse dieting. Conservative: Goal of less than or equal to ≤ 0.2% of body weight gained per week. A conservative reverse is recommended for people who want to absolutely minimize any fat gain and are willing to take a longer period of time to get their calories up. This reverse protocol is especially recommended for those who are not yet at their goal body fat but want to improve their energy expenditure and caloric intake, as well as those people who have reached their goal body fat but are not currently eating a sustainable amount of calories to maintain this on. We recommend starting at your maintenance calories, up to maintenance + an additional 10% calories. Moderate: Goal of less than or equal to ≤ 0.5% of body weight gained per week. A moderate reverse is recommended for people who want to get their calories up relatively quickly but don’t want to gain a lot of fat. We recommend setting your starting calories at maintenance + 10%, up to maintenance calories + an additional 20% calories. HOW TO SET UP A REVERSE DIET: CALORIES 74 Aggressive: Goal of less than ≤ 0.8% of body weight gained per week. An aggressive reverse is for people who wish to get their calories up very quickly and restore their metabolic rate as quickly as possible and are ok with gaining body fat. This reverse is typically reserved for people who have reached very low levels of body fat and want to recover from that extreme condition quickly, but not gain excessive amounts of body fat. We recommend your starting calories be set to your maintenance calories + 20%, up to maintenance calories + an additional 30% calories. Let’s use a new example of someone who’s TDEE is 1570 kcal/day. If they wanted to do a conservative reverse diet they would start at anywhere from 1570 kcal/ day (maintenance) to 1727 kcal/day (maintenance + 10%). If they wanted to do a moderate reverse they would start at 1727 kcal/day (maintenance + 10%) to 1884 kcal/day (maintenance + 20%). If they wanted to do an aggressive reverse it would be 1884 kcal/day (maintenance + 20%) to 2041 kcal/day (maintenance + 30%). As you can see, there is a large range of where you can theoretically take your calories to begin a reverse diet. If by the end of your fat loss phase you are feeling like absolute rubbish, low energy, low libid and your mood is constantly poor, then you may like to start with a more aggressive reverse in order to help you feel better faster. Initially you will regain body fat at a slightly faster rate, however once your energy levels are somewhat restored, you can transition back to a more conservative reverse diet approach. While it may be very tempting to hang on to your new lean physique, consider that someone who has been on highly restrictive calories has likely endured a myriad of physiological changes within the body. These include changes to your hunger hormones, which are all driving you to eat. So choosing the more aggressive approach might be the most sensible option, rather than trying to struggle through the initial weeks of a reverse diet consuming what is likely going to be still very restrictive calories, and thus placing you at a much greater risk of binge eating and uncontrolled weight regain. You could start with a more aggressive reverse initially until your hunger normalizes and then continue with a more conservative reverse from there. Calorie Cycling and Weekly Calorie Planning One of the most common questions we get regarding reverse dieting is “should I do refeeds, diet breaks, or calorie cycling on my reverse?” Since a reverse is HOW TO SET UP A REVERSE DIET: CALORIES 75 not an energy deficit there is no real benefit to having high and low calorie days unless you simply prefer to have high and low calorie days and it helps improve your overall adherence, especially in the immediate post diet setting where calories may still be low. If you choose to do calorie cycling it doesn’t seem to be detrimental when done within reason, so if that’s something YOU prefer, whether it be to facilitate eating out socially or to fuel performance in the gym, and it helps improve YOUR adherence, then go for it, just understand it’s not superior to just eating the same calories everyday. Let’s take our previous example of someone who has a TDEE of 1570 calories. Let’s say they decide to do a conservative reverse and start their calories at maintenance + 5% because they really want to limit fat gain. This equates to an average daily calorie intake of 1649 kcal. If we multiply that by 7 days in a week we come up with a weekly caloric budget of 11543 kcal to distribute across the week. Let’s say this person decides that they’d rather have more calories on Fridays and Saturdays so they can enjoy some adult beverages or eating out with friends, etc. So they decide to allott 1800 kcal per day to Friday and Saturday. How would the rest of their week look? 1800 kcal x 2 days = 3600 kcals. We then need to subtract that from our weekly calorie budget of 11543 kcal - 3600 kcal = 7943 kcal left to distribute across 5 days. 7943 kcal ÷ 5 days = ~1589 kcal/day for the remaining days. Now you don’t have to do high days as we stated earlier, and if you choose to include them, you don’t necessarily have to stick with 2 days either. You could include 1 high day, 2 high days, 3 days or even 4 days, etc. Just keep in mind that the higher you make your high days and the more frequently you have them, the lower your calories will need to be on other days in order not to exceed your weekly calorie budget. In general, We don’t really like to set high day targets by more than 50% above low days, not because their is science to support physiological downsides, but rather, we don’t want to condone someone starving themselves a few days per week in order to facilitate structured food binges. This does not help people to form a healthy relationship with food. That being said, intermittent fasting (IF) is very popular at the moment and many people are trying out different IF protocols. We are ok with this nutritional concept, so long as the individual realizes that there is no magic to IF, it does not boost your metabolism or increase fat loss compared to normal dieting when weekly calories are equated. Therefore, we only recommend IF if it fits YOUR HOW TO SET UP A REVERSE DIET: CALORIES 76 lifestyle and enables you to be more adherent to your overall dietary targets. I personally find that this approach works best with people who are on relatively low calories when they begin their reverse and would like to have some days with more room in their diet to be flexible so that they can have a night out, etc. It’s important to note that these days are not physiologically superior as calorie cycling has not been shown to improve body composition compared to weekly equated calorie diets, but that does not mean it can’t be a useful tool for you. Summary This chapter focused on helping show you how to set calories to begin a reverse diet. In summary, the most important thing is to understand your CURRENT maintenance calories/TDEE when you start the reverse so you can then base your initial caloric intake off that. Regardless of whether you choose a conservative, moderate, or aggressive reverse, you will be basing your intake off of your maintenance calories/TDEE. Also, keep in mind that once you have selected a conservative, moderate, or aggressive reverse, you don’t have to stay on it indefinitely. As we mentioned, you can start with an aggressive reverse for the first few weeks to help you recover from something like a contest prep or very restrictive diet, then switch to a conservative or moderate reverse once you start feeling better to help minimize additional unwanted fat regain. You could also start with a conservative reverse if you are really afraid of fat gain, but once your calories get higher and you feel more confident you could switch to a moderate reverse. There are a number of ways you can apply reverse dieting, but these should be based on your individual situation and goals. This is not a one size fits all method to reverse dieting. 6 77 HOW TO SET UP A REVERSE DIET: MACROS D etermining starting calories for a reverse diet is the most important step but we also need to figure out what kind of macronutrient breakdown you will be utilizing for a reverse diet. As we’ve laid out previously in our books The Complete Contest Prep Guide and Fat Loss Forever, we always start by determining our calories first, then we determine protein, and then the remaining calories are allocated towards carbohydrates and fats based on personal preference. While your calorie intake is the most important variable for determining your progress, macro ratios still matter. While all calories are created equal since a ‘calorie’ is simply a unit of energy, all calorie sources are not created equally when it comes to influencing energy expenditure and body composition. Protein We begin with protein because it is by far the most important macronutrient for improving lean body mass and increasing energy expenditure. The current government recommendation for protein is 0.8g/kg body weight. For an 80kg person this is 64g of protein per day. This intake was determined using nitrogen balance studies to determine what levels of protein prevented a negative nitrogen balance. Nitrogen Balance = Nitrogen intake (protein is the only nitrogen containing macronutrient) - Nitrogen loss (urine, feces, sweat). The amount of protein needed to keep you in a positive nitrogen balance is pretty small, but a positive nitrogen balance doesn’t mean that you’ve optimized body composition. In fact, the research suggests that intakes of up to 2-3x the RDA for protein may improve body composition compared to lower protein intakes closer to the RDA!1 2 This is likely due to dietary protein’s ability to stimulate 1. “Dietary protein for athletes: from requirements to optimum ....” https://www.ncbi.nlm.nih. gov/pubmed/22150425.

MPS is thought to be more responsive to nutrition than protein breakdown and thus we are able to increase MPS, it should lead to better accrual of lean body mass. When we tell people this information, many of them (especially women) say, “that’s great, but I don’t want to look like a bodybuilder.” Fear not, you are not going to accidentally get too muscular from consuming a high protein diet. Take it from two people who have spent the better part of their lives trying to get ‘too muscular’, it doesn’t happen by accident and without specifically training for that purpose. Besides, getting jacked isn’t all protein is good for. It turns out that high protein diets are better for body composition compared to normal or low protein diets.5 6 7 This is not only due to dietary protein’s influence on MPS, but also its effects on energy expenditure. Diets higher in protein have been shown to increase energy expenditure, likely from the thermic effect of food (TEF) being greater for protein compared to carbohydrate and fat.8 9 TEF refers to the amount of calories the body must expend to extract out the energy from the food you consume, much like how a car must expend energy to extract the energy from gasoline. The TEF for protein in fact, is far greater (~20-30%) com- 3. “Muscle protein synthesis in response to nutrition and ... - NCBI.” 30 Jan. 2012, https://www. ncbi.nlm.nih.gov/pmc/articles/PMC3381813/.

HOW TO SET UP A REVERSE DIET: MACROS 79 pared to carbohydrates (5-10%), and fat (0-3%).10 Interestingly, alcohol also has a relatively high TEF (~20%).11 What does this mean practically? While 100 calories from protein containing foods still contains 100 calories, ingesting it increases energy expenditure more than ingesting 100 calories from carbohydrate or fat. In the case of protein, around 20-30 calories will be expended to extract the calories from 100 calories of protein vs 5-10 for carbs, and virtually nothing for fat. Now before you decide to go on an all protein diet, keep in mind that the sustainability of a diet is incredibly important. If you’ve failed diets repeatedly because they were too restrictive, now is not the time to continue down that path. We definitely want to get enough protein, but there’s no reason to go crazy high with it, as this would come at the expense of other important food groups. So how much protein should we consume? Based on current scientific literature there doesn’t appear to be any negative health effects with intakes up to 4.4g/kg per day, so how much?12 We have put together a chart of recommended protein intakes based upon whether or not you are in a calorie surplus or a calorie deficit. There is evidence that you should consume more protein when in a deficit to help with maximum retention of muscle mass.13 We have also expressed these intakes as g/kg of LBM rather than total body weight. The reason for this is that lean tissues are the tissues that have protein requirements. Body fat or adipose tissue has very little requirement for protein intake. Usually this is not a big deal as higher body weights typically mean more LBM, but protein intakes can start to get weird when people have higher body fat levels. For example, a really obese person who is 150 kg and consumes 2.4 g protein/ kg total body weight would end up with a protein intake of 360g per day which is really high, even though their LBM might only be 90 kg. Their protein intake 10. “Influence of autonomic nervous system on nutrient-induced ....” https://www.ncbi.nlm.nih. gov/pubmed/8400596.

You’ll notice we’ve also included age as a variable here. As we age we become less sensitive to the anabolic effects of protein and it takes MORE protein to get the same anabolic response.14 15 16 Not only does age impact protein synthesis but so does energy intake. Eating in an energy surplus is protein sparing and eating in an energy deficit increases protein catabolism, therefore protein intake should be adjusted according not only to age and body weight but also energy intake.17 During a reverse diet, calories will be increasing so you may wish to lower your protein intake slightly compared to your protein intake during caloric restriction so that you can consume greater carbohydrates and fats. Alternatively, if you find that you are still very hungry post diet, it may be best to maintain a high protein intake until your hunger levels subside, as protein has been shown to have a greater ability to satisfy hunger, similar to a diet rich in fiber. This boils down to personal preference. 14. “Aging Reduces the Activation of the mTORC1 Pathway ... - NCBI.” 15 Jan. 2016, https:// www.ncbi.nlm.nih.gov/pmc/articles/PMC4728660/.

HOW TO SET UP A REVERSE DIET: MACROS 81 Carbohydrates Carbohydrates have gotten a bad rap in recent years with numerous influencers, health professionals, and celebrities speaking out against the ‘evils’ of carb consumption. They have been blamed for the development of numerous diseases including type 2 diabetes, heart disease, cancer, and numerous others. Carbohydrates serve important functions in the body as they are sources of glucose. Glucose is one of the main fuels for working muscles as well as other organs including the brain. Anaerobic exercise in particular can only be fueled by glucose and NOT fats and is therefore very important for optimal performance during intense exercise.18 Now carbohydrates are not NEEDED to survive which is something that low carbohydrate advocates use in order to justify their low carb recommendations. The body is rather clever in that it can make glucose from other non glucose containing molecules. In fact protein and dietary fats can be broken down and converted through various chemical reactions into glucose in order to ensure continued energy production. Further, in cases of very low carbohydrate, we can also produce ketone bodies which can be used as a secondary fuel source. In fact you may be familiar with the recently popularized ketogenic diet in which carbohydrates are very low and fats very high. This produces ketones which the body can then use as an energy substrate and is essentially why we can still survive on zero carbohydrate intake. This being said, just because carbohydrates are not essential in order to survive, it doesn’t mean they aren’t helpful. In fact, low carbohydrate diets may actually impair lean body mass accrual during overfeeding.19 That said, it appears that in the context of fat loss a low carbohydrate, high fat (LCHF) diet is similarly effective as a high carbohydrate low fat diet (HCLF) for fat loss when both calories and protein are equated.20 In 18. “Carbohydrate Availability and Physical Performance - NCBI.” 16 May. 2019, https://www. ncbi.nlm.nih.gov/pmc/articles/PMC6566225/.

HOW TO SET UP A REVERSE DIET: MACROS 82 the context of reverse dieting, it appears that overfeeding either carbohydrate or fat is equally fattening.21 That said, overfeeding carbohydrate seems to have a more pronounced effect on leptin secretion in the short term, although we aren’t sure how that relates to long term changes in BMR.22 It may be tempting to have a reverse diet which focuses on increasing carbohydrate relative to fat due to the effects of carbohydrates on leptin in the short term. There is some data in animals which suggests that in the immediate post diet period a higher ratio of carbohydrate to fat may be preferable to a high fat diet for limiting fat regain, and this is believed to be due to the downregulation of beta oxidation and fatty acid metabolism in fat tissue during a calorie deficit, but I wouldn’t exactly call this data extremely strong.23 That said, if you are someone who has been on a really restrictive diet, lost a lot of body fat, and likely experienced a lot of metabolic adaptation, it may be slightly preferable to emphasize carbohydrate vs. fat during the initial reverse diet period but we certainly can’t state that with any great degree of confidence. Overall, in a post diet period and moving forward into a long term reverse diet, the most important factor will be your adherence. Despite possible small mechanistic advantages to consuming lower fat and higher carbohydrate, that is easily trumped by using a macronutrient breakdown that is most easy to adhere to for the individual. If that means they consume a higher ratio of fats to carbohydrates but it allows them to be consistent to their calorie target, that is far more important than attempting to consume a high ratio of carbohydrate to fat if that is something that causes the individual to not be able to adhere to their overall plan. 21. “Effects of isoenergetic overfeeding of either carbohydrate or fat in ....” https://www.ncbi. nlm.nih.gov/pubmed/11029975.

Dietary fats are the most energy dense macronutrient we consume (over double what carbohydrate and protein contain at 9kcal/gram) and thus a high fat intake can lead to overconsumption of total calories. On the other hand, extremely low levels of dietary fat intake have been demonstrated to lower testosterone and have a host of other undesirable side effects.24 25 High fat diets on the other hand, seem to contribute to post diet weight rebound.26 What is less clear is whether this post diet rebound is due to the increased fat intake vs. carbohydrate (assuming calories are equated) or simply because high fat diets also tend to be higher in calories, further, they are often found in highly palatable, high reward food sources. We tend to agree that high fat and high carb diets are probably both similarly fattening based on the available human data.27 Our recommendations therefore focus on consuming a ratio of carbohydrate to fat that is sustainable for the individual and best facilitates long term adherence. For the majority of people this will be a reasonable balance of both carbohydrate and fat. Typically, if carbohydrates are too restricted or fats are too restricted, adherence decreases. That said, it is completely reasonable that certain individuals may feel better on a carb restricted diet or a fat restricted diet, and in those cases, personal preference should typically take precedence over proposed mechanistic differences between HFLC and LFHC diets. 24.

First dietary fats were under fire for heart disease and obesity. Now more recently the focus has shifted to carbohydrates. The simple truth, however, is that carbohydrate and fat metabolism are always linked. Consuming more or less carbohydrates will inherently impact fat metabolism, especially when considered in the context of calories being equated between LCHF and HCLF diets. You see, when carbohydrate intake increases, carbohydrate oxidation increases and fat metabolism decreases. Conversely,when carbohydrate intake goes down, carbohydrate oxidation decreases and fat oxidation increases.28 Thus the two are intrinsically linked. This information has led many low carbohydrate proponents to tout the superiority of low carbohydrate diets. After all, decreasing carbohydrates increases fat oxidation, that must mean low carb diets are better for fat loss and limiting fat gain right? Not really. First off, we don’t see significant differences in fat loss in studies where calories and protein are equated and carbohydrates and fats are varied, in fact we actually see a small fat loss benefit (16g per day extra fat loss) with low fat diets.29 This is likely because overall body fat loss is the balance between the amount of fat that you store vs. the amount of fat you burn (oxidize). On a LCHF diet you indeed burn much more fat, but you also store much more fat because you are eating more fat. On a HCLF diet you will burn much less fat, but you are also consuming less fat so you store less fat. The net gain or loss of body fat will depend upon your overall energy balance. 28. (n.d.).

The difference between stored and burned fat equals the net fat balance. In this example, a higher fat diet causes greater fat burning, but also greater fat storage compared to a calorie equated low fat diet that produces a lower rate of fat burning but also lower fat storage. The net fat balance between the two diets is equal. This may seem strange but it is how the body changes fuel selection and it’s really quite elegant. The vast majority of the fat we store (>98%) is from dietary fat and not carbohydrates.30 Carbohydrates tend to be oxidized or stored as glycogen while very few wind up in fat tissue through a process called de novo lipogenesis. So while a HCLF diet will reduce fat oxidation, it also means that there will not be many fats from the diet to be stored in fat tissue. Whereas a HFLC diet will drastically increase fat oxidation, but will also lead to a greater amount of fat storage due to the increased dietary fat consumption. In both cases, the overall net gain or loss of body fat will depend on the individual’s energy balance. This is likely why we do not see much difference with regards to fat loss and energy expenditure when calories and protein are equated but we vary the amount of carbohydrates and fats in the diet.31 In the context of reverse dieting, this means that once we set our calories and protein, we can 30.

Based on the research and our 2000+ clients between us we have developed the following method for determining macronutrients for determining initial fat loss, muscle gain, maintenance, and reverse dieting: Step 1: Determine starting calories Step 2: Determine protein intake based on deficit vs. non-deficit and age. Subtract calories allotted to protein from total calories to get remaining calories from carbohydrate and fat Step 3: Select carbohydrate and fat breakdown based on preference and what is best for your own adherence. Setting Protein We base protein requirements on a few things. Looking at the most current research on protein intake and body composition, we feel confident saying that a high protein diet is likely superior for body composition and lean body mass compared to a normal or low protein diet with a recent systematic review concluding that an intake of 2.3-3.1g/kg of LBM is likely optimal for resistance trained individuals during caloric restriction.32 33 34 Under non-calorie restricted condi32.

That is, increases in carbohydrates and fats provide energy substrates to spare protein from oxidation (breakdown). When in energy balance or surplus, protein needs decrease to approximately 1.8-2.6g/kg LBM based on a recent review.35 For those who are reverse dieting, it means that you will be in energy balance at minimum and possibly a small surplus at times. Age can also factor into this as protein needs increase during aging, as mentioned earlier due to a reduced anabolic response to protein.36 Here is a handy chart we developed for determining protein intake based on our interpretations of the research regarding protein intake in a deficit vs. not a deficit and age. That said, you probably don’t need to worry about using the deficit protein ranges as a reverse diet is at least at energy balance/maintenance calories, so if you’ve been dieting and are planning to use a reverse diet to come out of a deficit phase, you can certainly drop your protein a bit and still get all the anabolic benefits of protein. That said, if you just really love protein like we do, there is probably no reason for you to reduce it. Just understand that jacking it up beyond a certain point will not increase anabolism further. There also doesn’t appear to be side effects to consuming a disproportionately high amount of protein either as intakes of up to 4.4g/kg have not shown negative side effects.37 38 In short, do what you enjoy most and what you feel is best for your adherence. I (Holly here) love protein and always end up on the higher side of the recommendations because over the years, I have found recipes and certain foods that are highly satisfying, and this suits me better than allocating those calories to carbohydrates and fats. That said, if you are perfectly happy at the lower end of a range and would rather allocate more calories to carbohydrates and fats you can do that as well.

If she decides that she wants to err on the high end of the recommendations and go with 2.3g/kg LBM we get 59.5 kg LBM x 2.3g/kg LBM = ~137g protein per day. Remember, if she LOVES protein and decides to have more, that’s fine also but there’s probably no need to go higher. Now that we know her protein we have to remove those calories allocated to protein from her total calorie budget. 137g protein x 4 kcal/g protein = 548 kcal. 1890 kcal - 548 kcal = 1342 kcal remaining for carbohydrates and fats. Setting Carbohydrates and Fats Once protein is set we now need to determine how we will allocate remaining calories to carbohydrates and fats. As we stated previously, it does not appear that the ratio of carbohydrate to fat in the diet makes a difference in terms of fat loss or fat gain. One caveat that may be worth mentioning is that it appears that if we go to the extreme where fats are very high and carbohydrates are very low to the point where the diet becomes ketogenic, there appears to be somewhat of an inhibition on the accrual of lean mass.39 This could be due to the increase in nitrogen excretion seen with a ketogenic diet and possibly due to the reduction in insulin.40 In addition to insulin’s effects on lipolysis and glucose uptake, it also decreases muscle protein breakdown, improving net protein balance.41 Therefore, if increasing muscle mass is also a goal with reverse dieting, it may be more optimal to stay away from too low of a ratio of carbohydrate to fat. Likewise, low fat diets (<25% calories from fat) have been shown to reduce testosterone levels, so it may also be wise not to drop fat too 39 .“Efficacy of ketogenic diet on body composition during ... - NCBI.” 9 Jul. 2018, https://www. ncbi.nlm.nih.gov/pmc/articles/PMC6038311/.

HOW TO SET UP A REVERSE DIET: MACROS 89 low either.42 43 That said, if gaining muscle is not important to you and your only goal is to increase your caloric intake and minimize fat regain, do whatever ratio of carbohydrate to fat you prefer, though we find that most people prefer somewhat of a balanced approach between 70/30 and 40/60 ratio of calories remaining from carbohydrates/fat once protein calories have been excluded. If we take our previous example of someone who is starting her reverse at 1890 kcal at 137g protein (548 kcal from protein), that leaves 1342 kcal left for carbohydrates and fats. If we choose a 60/40 ratio (a balance that we find works for many people) of remaining calories allocated to carbs/fats respectively we get the following amounts of carbohydrates and fats. Carbohydrate: 1342 kcal x 0.60 = 805 kcal from carbohydrate. 805 kcal ÷ 4 kcal/g = ~201g carbohydrate Fats: 1342 kcal x 0.40 = 537 kcal from fat. 537 kcal ÷ 9 kcal/g = ~60g fat. This would put her overall starting reverse macros at 137g protein, 201g carbohydrate, and 60g fat. What if she wanted to do 50/50? Carbohydrate 1342 kcal x 0.50 = 671 kcal from carbohydrate. 671 kcal ÷ 4 kcal/g = ~168g carbohydrate Fats: 1342 kcal x 0.50 = 671 kcal from fat. 671 kcal ÷ 9 kcal/g = ~75g fat So in this case her starting reverse diet macros would be at 137g protein, 168g carbohydrate, and 75g fat. If you hate math and would rather have an easy way to reference carbohydrate/ fat breakdown based on remaining calories from carbs and fats we created a quick reference chart just for that reason. 42. “Decrease of serum total and free testosterone during a low-fat ....” https://www.ncbi.nlm. nih.gov/pubmed/6298507.

The column on the far left is the calories remaining to distribute to carbohydrate and fat. Each column thereafter shows the breakdown of grams of carbohydrate/ fat each particular breakdown at each remaining calorie level would provide. HOW TO SET UP A REVERSE DIET: MACROS 91 Try to remember not to get too hung up on individual starting macros. At the end of the day the most important thing is your daily calorie intake, followed by your calories and protein, followed by your macros. Even if you select an amount of macros that are ‘off’ to start, there is no need to worry as we will discuss how to adjust them as you progress to optimize your response. Summary To determine starting macros for a reverse diet: 1. Set starting reverse diet calories (see chapter 5) 2. Set protein based on LBM, age, and deficit vs. non-deficit. 3. Subtract calories allocated to protein from total calorie intake 4. Distribute remaining calories to carbohydrates and fats as per personal preference 7 92 CONTINUING THE REVERSE DIET C ongratulations, you’ve made the commitment and you are on your way. You’ve got your starting calories and macros figured out and you’ve begun the process, but this is only a small portion of the battle. It’s critically important to assess your progress weekly during a reverse diet and determine what adjustments, if any, should be made. There are a few different measures we are going to use to assess progress including body weight, body fat (if available), pictures, waist circumference (if available), and your own subjective feedback. Tracking Your Progress While it is popular to say things like “the scale doesn’t matter” the reality is that it does. What we really should say is it’s not the only thing that matters, but it is a pretty good indication of how things are generally going. It also is the most objective out of all the measurement tools we use, meaning there is less room for human error. As many of you already know, however, the scale can fluctuate dramatically from day to day. So how do we account for this? Our preferred method is to weigh in everyday and then average the weights over the course of a week to get the best idea of what your weight is really doing. While it’s not uncommon for you to see big fluctuations from day to day, fluctuations due to shifts in fluid are much less likely to make a big difference in the weekly average. Therefore, we recommend weighing in each day, first thing in the morning after you wake up, after your morning trip to the bathroom, and taking the average of those weights. Now if you are someone who really struggles with anxiety and the scale, there are a few strategies you might be able to use to help reduce this. The first is if you have a supportive friend, partner, or family member that you live with, you can weigh in and not look at the scale and just have them record the weight for you. Then you can have them average it at the end of the week and show you the average. If you don’t have that option, another alternative would be to not look CONTINUING THE REVERSE DIET 93 at the scale but point your phone at it and take a picture each day and wait until the end of the week to look at the weigh ins and calculate the average weight for the week. If you find all of that still too anxiety provoking, then perhaps weigh in once per week, but just understand that since it is just a single measurement, it will be much more prone to large fluctuations from week to week. For example, maybe the morning you decided to take your weight, happens the day after you ate significantly more dietary fiber than other days, or perhaps you ate higher sodium meal. Both of those examples could lead to weight fluctuations. So as you can see, there are some benefits of taking your weight regularly to ensure your weight is not skewed. Body fat is a little trickier. There are many ways to measure it but most of them aren’t practical to have done weekly. Further, body fat measurements can fluctuate DRASTICALLY depending upon hydration status since fluid registers as lean body mass. For example, let’s take someone who is 15% body fat at 80 kg. That means they have 68 kg LBM and 12 kg FM. If they get a DXA (dual energy x-ray absorptiometry, considered the gold standard in research), showing those values but then immediately chug 4 liters of water and don’t pee, that means they would add 4 kg (1 L approximately equals 1 kg) of LBM instantly. Now look what happens to their body composition: the 4L increase in fluid means they increased their LBM to 72 kg and 12 kg FM and 84 kg body weight. Their new body fat percentage = 100*(12 ÷ 84) = 14.3% body fat, almost a full percent drop just from chugging 4 L of water. Food in your GI also registers as LBM. So imagine if you got a DXA done in the afternoon after drinking and eating all day, you could easily register several kg more LBM, then if you went back in the next week in the morning and had a DXA done in a fasted state, you could register as having several kg less LBM and by default, a greater body fat percentage. As such, we recommend only using body fat assessments that can easily be done at home, in the morning, after going to the bathroom.This leaves only calipers, hand held devices (like Omron), and scales that also measure body fat. Are they as accurate as DXA? Probably not, however keep in mind even DXA has very limited accuracy. All measures of body fat use equations, algorithms, and various assumptions for their calculations. What is most important is that you use the same measurement tool, the same way, at the same time, EVERY TIME. For example, let’s say that you have your body fat assessed via calipers CONTINUING THE REVERSE DIET 94 and it registers as 12% when in reality, you are really 15%. If a few weeks later you consistently measure yourself at 9.5% body fat calipers, and maybe you are really ~12%, you still can be pretty confident that you lost fat because the relative change is likely still pretty accurate. No matter how you choose to assess body fat (if you choose to, you can just use the scale if you want), just make sure you are consistent with it. Take it once per week, on the same day, after you wake up and use the bathroom, weigh in, and then take body fat. We would measure it three times and then take the average of the three readings. Other body measurement tools are similar to body fat. There is probably less error. We would assess waist (around the belly button), arm circumference at the largest point, and hips. Take three measures of each to minimize error. With regards to pictures (if you choose to assess them), we recommend taking them once per week on the day where you also do body fat and circumference measures. Take front, side, and rear facing pictures, in the same place, at the same time. We recommend turning the lights on and using a flash on your camera just to protect against changes in lighting, as more or less sunlight in the room you are taking your photos can change how your physique looks. Taken together, we will use all these measures to assess progress. If you don’t have a coach (which we will assume you don’t to be safe), you will need to do weekly check ins to assess your progress. If you are within the allowable weight gain for your chosen reverse diet rate then you can continue adding calories at the respective rates for the reverse (discussed below). If you go over your ‘maximum allowable weight gain’ for that week, then you need to also assess body fat, pictures, and circumference measurements. If your weight increased above the max allowable gain, but your body fat hasn’t gone up, you don’t appear to have gained body fat, your circumference measures (especially waist) haven’t increased, and your clothes don’t feel tighter, then you can continue adding calories the next week if you wish. It’s absolutely possible that you have simply gained lean body mass. If you prefer to remain more conservative, you can choose to not add calories. Or for arguments sake, let’s say you didn’t gain above the max allowable gain, but you were really close to it and you have been really close to it for a few weeks without exceeding the threshold, you could choose to not add calories for a week or two in order to make sure your CONTINUING THE REVERSE DIET 95 weight stabilizes before adding more calories. Keep in mind that this is your reverse diet and you shouldn’t add calories more quickly than you are comfortable with, but we think it’s important to give you guidelines. Remember that these are not rules, simply guidelines (but we think they are pretty damned good). Calorie Additions Let’s talk about each type of reverse diet and what calorie additions we recommend based on your progress. Typically, we recommend increasing calories from carbohydrates and fats, rather than from protein. This is because your protein is already going to be more than enough to optimize body composition if you followed our protein guidelines and adding calories actually reduces protein needs further. Therefore, if protein is already set within our suggested ranges, we recommend keeping it the same during the reverse diet. Conservative: Max allowable weekly gain ≤0.2% of body weight gained per week. If this is not exceeded during your weekly check in we recommend adding a 1-3% increase in calories from carbohydrates and fats. Moderate: Max allowable weekly gain of ≤0.5% of body weight gained per week. If this is not exceeded during your weekly check in we recommend adding a 3-6% increase in calories from carbohydrates and fats. Aggressive: Max allowable weekly gain of ≤0.8% of body weight gained per week. If this is not exceeded during your weekly check in we recommend adding a 6-9% increase in calories from carbohydrates and fats. If we use our example from the previous chapter of a 30 year old, 70 kg female who is doing a conservative reverse at maintenance + 5% of calories to start. Her starting calories were determined to be 1890 kcal coming from 137g protein, 201g carbs, and 61g fat (using the 60/40 breakdown of remaining calories from carbohydrates/fats). Recall that her calories distributed to carbohydrates and fats were 1342 kcal (once 548 calories allocated to protein were removed). Let’s say during her first check in her weight increases by 0.2 kg. Her maximum allowable weight increase should have been 0.14 kg. (70 * 0.002) = 0.14. Since CONTINUING THE REVERSE DIET 96 0.2 kg is more than the allowable 0.2% increase, it is slightly more at .28%, (0.2 ÷ 70)*100 = .28%, she should therefore hold her calories steady. During her next update she doesn’t have a weight increase and stays at 70.2. In that case she would then add 1-3% of calories from carbs and fats. If she chooses to stay relatively conservative and add 2% calories, that would be 1890 kcal x 0.02 = ~38 kcal. Recall that previously, she had 1342 kcal remaining for carbs and fats. 1342 + 38 = 1380 kcal. If she wishes to use the same 60/40 macronutrient ratio, 60% of 1380 kcals is 828 kcal to carbohydrates. 828 ÷ 4g/kcal = 207g carbohydrate. 40% remaining calories can be used for dietary fats which is 552 kcal. 552 kcal ÷ 9 = 61.3g (rounded to 61g) fat, (a non-significant increase). Now her macros are 137g protein, 207g carbohydrate, and 61g fat. Now we know what you are thinking, that’s basically nothing! An extra bite of food each day for a week, what’s the point? You are correct, it’s not much but the important thing to remember is the summation of these additions over time. If you did this every week for 6 weeks, 6 x 38 kcal = 228 kcal. That is a significant increase. You can’t just jump up straight to a 228 kcal increase and expect your body weight not to increase. You have to give it time to adapt. That is why the rate of calorie additions are important. You are giving your ‘maintenance range’ calories (more on this later) time to shift and dissipate the increase in energy rather than just loading up all the calories at once. Now what would this look like if we took the same update but she was on a moderate reverse? Well in that case a 0.2 kg increase in body weight over her first week (0.28% of her body weight) would NOT cause to her exceed her maximum allowable weekly weight gain which we defined above as 0.5% per week. Then if she decided to add 5% calories, based on our recommendations above, that would equate to 1890 kcal x 0.05 = ~95 kcal. 1342 kcal remaining from carbs/fats + 95 kcal increase = 1437 kcal from carbs/fats. 1437 kcal x 0.60 = ~862 kcal from carbohydrates. 862 kcal ÷ 4 kcal/g = 215g carbohydrate. 1437 kcal x 0.40 = ~575 kcal from fat. 575 kcal ÷ 9 kcal = ~64g fat. Now her macros are 137g protein, 215g carbohydrate, and 63g fat. CONTINUING THE REVERSE DIET 97 Simplifying the Increases Now Layne and I like math and we don’t mind doing it, however, we understand that it can be tedious for many of you. So we have broken it down into a nice little table for you based on your ratio to Carbohydrate/Fat. Kcal Increase Vs.

Another Option If you don’t want to mess with as much math or the table, another option is to simply increase by a certain percentage of your current carbohydrate and fat intake, rather than total calories. Since protein is typically held steady during a reverse diet and the increases are coming from carbohydrate and fat, you could choose to just increase by a certain percentage of carbohydrate and fat. The only caveat to this is that if your protein is set really high, your increases in carbs/fats may be disproportionately lower at first compared to using the total calorie method we discussed first. For example, if you were on 2010 calories per day on a conservative reverse consuming a hefty amount of protein i.e.250g per day, with remaining calories being 150g from carbohydrates, and 45g fat (60/40 ratio of CHO/Fat) and you applied a 5% increase from carbs and CONTINUING THE REVERSE DIET 99 fats (the upper end of our suggested range for a conservative increase, see below), you would only end up increasing by 8g carbs and 2g fat (50 calories) whereas if you were using the upper end of the caloric increase (3% increase in calories from carbs and fats) that would be 60 calories, 9g carbohydrate and 3g fat (2.6g but rounded up to 3g). Thus it’s a slightly smaller increase, so if you prefer the method of simply increasing carbs and fats as a percentage of your total intake, that will work great for most people and only really becomes ‘off’ if your protein is set relatively high and your carbs/fats are low. Conservative: Max allowable weekly gain ≤0.2% of body weight gained per week. If this is not exceeded during your weekly check in we recommend adding a 2-5% increase in grams of carbohydrates and fats. Moderate: Max allowable weekly gain of ≤0.5% of body weight gained per week. If this is not exceeded during your weekly check in we recommend adding a 5-8% increase in grams of carbohydrates and fats. Aggressive: Max allowable weekly gain of ≤0.8% of body weight gained per week. If this is not exceeded during your weekly check in we recommend adding an 8-12% increase in grams of carbohydrates and fats. Just to provide another example, let’s take our previous case study of our female consuming 137g protein, 201g carbohydrates, and 61g fat. If she was within her allowable weight gain for a conservative reverse and decided to add 4% carbohydrates and fats, she would increase by 8g carbs (201 x 0.04 = 8.04) and 2g fat (61 x 0.04 = 2.44). This method is much simpler as you can see and not quite as complicated as determining calorie increases then converting to grams of carbohydrates and fats. That said, it’s not quite as accurate, but we thought it was important to give you both options. CONTINUING THE REVERSE DIET 100 Trust the Process Many of you (ladies especially) may struggle with adding calories if you have a history of yo-yo dieting or chronic dieting. It will get even tougher if you start to see the scale going up. That is why it is so important to COMMIT to the process. If you want to get out of the yo-yo mindset, you have to try something different. If you keep doing the same things you’ve always done, you will keep getting the same results you’ve always gotten. If you want a different result, you have to make different choices. It’s difficult to predict how your body will respond to a reverse diet, largely due to variations in NEAT between individuals. In fact, during overfeeding studies, many people gain weight but some people end up losing weight even when overfeeding by a predicted 1000 kcal over maintenance!1 This suggests that some people have extremely high NEAT adaptability, in that the increase in incidental movement, often due to increased energy availability outweigh the increases in calories. Some individuals on the other hand may not see proportionate increases in NEAT. It is likely that some of you will add some weight during a reverse diet and that is OK! Especially if the increase in weight is offset by a disproportionate increase in energy expenditure. For example, if you add 2 kg over the course of 16 weeks, but you are also able to add 500 kcal to your maintenance calories, it’s a pretty good trade because it’s likely you will take it off quickly when you begin dieting! Some of you will gain more than this, some of you will gain less, some of you may even lose weight while reverse dieting. The most important thing is that you stay committed to the process. If you reverse diet for 4 weeks and add 2 kg and bail on your reverse diet only to go back to yo-yo dieting, nothing is going to change. If you are gaining weight on low calories then that just emphasizes how much MORE important that you stay out of a deficit for a while to restore your energy expenditure to a more normal level. For a quick reference guide as to what constitutes a ‘normal’ maintenance calorie level, we have put this into Table 9.1 in chapter 9. Most of you reading this book will likely choose a conservative or moderate reverse diet approach. It’s very important to note that while we can try to predict 1. (n.d.).

That is, they will lose a lot in one week, then nothing the next, then lose another chunk the following week, etc. That is normal! Let us state it again so it sinks in, THAT IS NORMAL. It’s also normal while reverse dieting to not gain any weight for several weeks in a row and then BOOM, you gain a kg. This is also normal and we don’t have a great way to explain why things happen like this. One obvious reason is fluid fluctuations, but typically fluid fluctuations normalize back to a regular weight after a few days. We have certainly seen hundreds of instances with clients where they gain a chunk of weight and it doesn’t come off during a reverse diet, and likewise during dieting they lose a big chunk of weight and it stays off, even though the caloric surplus/deficit they were on in no way predicted that much change in weight. A possible explanation for some of this erratic weight loss and weight gain during these situations may be explained by a concept that Layne and Peter discussed in Fat Loss Forever called ‘maintenance calorie range.’ Maintenance Calorie Range where you think maintenance is 2350 cals 2650 cals 2500 cals Weight Loss Maintain Weight Weight Gain Figure 7.1: Maintenance calorie range illustrating the range at which you would maintain your weight. In order to see weight gain or loss, you must get outside of this range. CONTINUING THE REVERSE DIET 102 The concept of a maintenance calorie range is that we have a range of calories where we will maintain our weight and the buffering of that range is likely due to changes in NEAT/BMR. When we explain this to people we typically use the example of having someone cut 50 calories out of their diet. If they did that, theoretically they should lose ~0.1 kg per week. We promise that if you have someone cut 50 calories out of their diet you will not see any meaningful change in weight other than normal day to day fluctuations. In fact, some people have quite a wide maintenance range, where cutting 100-200 calories out of their diet does not produce significant weight loss even though they are maintaining their weight. Likewise, we’ve observed people not increase in weight even though adding decent amounts of calories. What is likely happening is that they are modifying calories within this buffering range. We estimate that most people have a maintenance range of calories between 150-300 calories where their weight doesn’t shift. For example let’s take the case of someone reverse dieting who has been adding 50-100 calories per week for several weeks with no gain in weight, but after they cross a certain point all of the sudden they add 1 kg. It’s likely that during the time they were adding calories, their energy expenditure was going up as they stayed within their maintenance range, so they were pushing the upper end of this range until one week they finally moved outside of the range and their weight moved. Now let’s take the case of this same person who had been reverse dieting a while, pushing the upper end of their maintenance range. If they decided they wanted to do a slow approach to a fat loss and only lose weight slowly and they start by cutting only 300 calories per day from their diet, they might not lose anything because they simply shifted from one end of their maintenance range to the other. Many of you have likely observed this phenomenon when attempting to lose fat during a dieting phase. You lose weight on a certain amount of calories for a while until eventually your TDEE adapts and those calories become your new maintenance where you aren’t losing weight. So if you want to keep losing weight at the same pace (say ~0.5 kg per week) do you then need to drop another 500 calories to continue weight loss at the same level? Not typically, in fact we’ve found with our clients that just a ~3-8% reduction in calories will often be more than sufficient to restart weight loss. If Layne’s theory on maintenance calorie range is correct, then it’s likely as someone is losing fat and they pla- CONTINUING THE REVERSE DIET 103 teau, they are plateauing at the lower end of their maintenance range. Thus, a small drop in calories may likely be sufficient to get them back into a significant deficit and continue losing weight. Now we aren’t saying that this concept is supported by empirical data, because it’s not. If you look on pubmed for maintenance range studies, you won’t find them, this is highly nuanced, however we do have data that suggests this based on some of the overfeeding studies that fail to produce weight gain even though they should. It also fits with the 20+ years of coaching experience between the two of us. So don’t get discouraged if you see some bumps in weight here and there that seem strange, that’s normal. Continuing the Reverse Diet Reverse diets are typically long endeavors, or at least they should be. If you are recovering from a previous diet or chronic dieting or yo-yo dieting, then the should be even longer. In fact, some data suggests that the length of post diet recovery needs to be at least as long as the actual diet itself in order to properly recover metabolic rate as well as normal hormonal profiles.2 For those of you who fall into this category, keep in mind reverse dieting may be even more difficult than fat loss phases. Sure you get to eat more, but fat loss diets are the short term gratification of the nutrition world. You get to see relatively fast changes compared to trying to gain muscle. In the case of trying to increase your energy expenditure, the changes are even more subtle because you can’t actually see them. These changes are happening endogenously to your metabolic rate and energy expenditure. This leads many people to get discouraged and quit because they aren’t seeing the positive physical changes they want right now. If you are a chronic/yo-yo dieter you need to listen to what we are going to tell you: do not sacrifice what you want most for what you want right now!

If you keep jumping from one fat loss diet to the next constantly searching for a quick fix just ‘one last time’ you are basically addicted to dieting. How is that working out for you? If you want a different result, it’s time to make a different choice. We know eating more and seeing occasional increases on the scale might be a daunting experience for you, but try to look at the plus side. Now that you are eating more, your training isn’t going to be garbage. Now you can actually put in some real effort at the gym and even if you were putting in effort before, imagine what you’ll be able to do now that you are fueling your body properly. Further, focus on the improvements in your strength and performance, and the fact that a good portion of the weight you add likely won’t be fat, there is a good chance if you continue training hard (more on this in the next chapter) that you will be adding lean body mass which will make you look better in the long run and improve your metabolic rate. Adherence If you find that you are gaining much more weight than you should be on a reverse, we suggest dialing it back in terms of the aggressiveness of the reverse. If you are already on a conservative reverse diet and finding you are gaining weight too fast, don’t increase your calories for a few weeks, but also take a real accounting of what you are eating. If you are finding that you are gaining more weight than you should, are you REALLY being accountable for the foods you are eating? Are you eating out multiple times per week? Are you consuming alcohol and not tracking it? Are you being really lax on the weekends? Are you tracking licks, bites, and foods you might be snacking on? Are you eating entire packages of gum each day? Are you consuming a lot of diet products that claim to be low in calories (hint: many times they aren’t when you do the math). If you can answer yes to any one of those then before you claim that ‘my reverse diet isn’t working’ make sure you do a thorough accounting of your behaviors and what you are REALLY consuming each day. It’s likely you are eating more calories than you think. That’s not a knock either, the vast majority of people do, even dietitians, like me (Holly speaking) have been shown to underreport their daily calorie intake by 223 calories per day on average (non-dietitians under CONTINUING THE REVERSE DIET 105 reported by 429 calories per day)!3 Is it possible that you really are nailing your calories and macros and gaining more weight than you want on a reverse diet? Sure, it’s entirely possible. In our experience however, consistent weight gain can often be traced back to a lack of adherence. We aren’t even talking about people going on huge food benders. Often it’s simply people who forget to track a few snacks here and there, or they were simply less active without realizing it. Perhaps they don’t track the pack of sugar free gum they are chewing. They eat food earlier in the day and don’t track it then forget everything they ate when they go to enter it in. We have both done that. Or you eat often and simply can’t control how things are cooked and and what goes in, thus you can only take a guess at the macros, and this can be way off. We aren’t saying never go out to eat. We also aren’t saying you need to weigh out all your food down to the gram every meal for the rest of your life. What we are saying is that if it’s not going how you want, then dial down the reigns for a week and make sure you are being accurate with your intakes. If you are, then perhaps it’s time to back off on the calories by 10% and let things stabilize for a few weeks. If not, then at least you know what to do moving forward to improve your results. Adherence = results. Adherence can be tricky on a reverse diet, especially during the initial phases of the process. Many people have success in adhering to a fat loss diet, but then struggle during a reverse diet when their calories still aren’t high but now they no longer have the immediate positive feedback of losing weight to provide additional motivation. Some people also make the choice to pursue a conservative reverse diet when it is not appropriate for their situation. We see this time and time again in competitors who want to stay show lean for extended periods of time. They choose a conservative reverse and then consistently fall short in the adherence category by overeating their targeted macros and calories. Not only that, but many of them struggle with binge eating because they are not able to hit their targets which causes them to enter ‘fuck it mode’ and binge. Instead of staying in this unhealthy cycle of attempting to hit calorie targets that are obviously too low for them, what we recommend for people who absolutely want to minimize fat gain but are struggling with adherence is to increase 3.

Even if they get some weight, it’s usually a very small amount and they often gain less weight than if we would have kept them trying to hit those targets that were too low for them. Once they are able to start feeling like they are getting some ‘wins’ in the adherence column, things typically improve quickly. As a side note, on any reverse diet, regardless of goal or situation, you should be on a level of calories that you can consistently adhere to. If you are not able to consistently adhere to them because they are too low, then it is not appropriate for you. If you choose a conservative reverse and calculate how many calories and macros you should be on for a conservative reverse and know that it will be very difficult for you to hit those, you probably should raise them to a level you know that you can consistently adhere to. Summary Where you start with a reverse is a small part of the success of a proper reverse diet. Monitoring your progress each week and being consistent with your own check ins and self assessment is a critical part of success. Select a reverse diet pace (conservative, moderate, aggressive) that fits with your goals and individual situation. If you are struggling with compliance, you may need to consider increasing calories to a level that is easier to consistently hit. If you are gaining weight faster than you would like, then keep calories steady for a few weeks until your weight has stabilized or slightly back off your caloric intake for a few weeks and then try resuming the reverse diet. As with all things fitness, adherence and consistency are the number one driver of success. 8 107 TRAINING AND CARDIO T hus far we have only discussed the nutritional components of reverse dieting, but it’s very obvious that training is important. As we already mentioned, exercise is an extremely important component of weight loss maintenance and energy expenditure. In fact, it has been shown that of those people who keep the weight off for 9 years, they averaged over 200 kcals more energy expenditure from physical activity per day than normal weight controls who didn’t exercise.1 The purpose of this chapter is not to provide you with training and cardio programs, as that would be way beyond the scope of this book. We know the popular move in books is to throw in a bunch of workout routines, and yes we will write books in the future for this, but to be quite frank, anything we throw in would simply be a cookie cutter program that isn’t tailored to you. Training needs to be tailored to your specific needs. In fact it’s much more than simply wanting to lose fat, reverse diet, or gain muscle. Effective programming stays the same regardless of nutritional goal. Whatever builds muscle best will maintain it best during a deficit. So reverse dieting is not cause to necessarily change your programming. Further, any programs we could list here would not take into account your current training status, current volume of training, and various other crucial training parameters. If you are someone who needs help with programming then we highly recommend the BioLayne Workout Builder as it can be customized to your goal, training status, weak points, and various other parameters.2 1.

Many of you are likely performing a combination of resistance training and cardiovascular exercise (aka cardio). It’s important to note that there is no single best way to resistance train or do cardio. As with diet, there are many ways to skin a cat. Many forms of resistance training and cardio will ‘work’ but we can determine from practical research that some general guidelines will work better than others. Our goal with this chapter is to provide you with general guidelines to follow for training and cardio as they relate to your experience with reverse dieting. For those of you who don’t exercise currently, we don’t want to tell you how to live your life, but you really should exercise. Exercise will drastically improve your health, even if it’s just a small amount, independent of weight loss.3 We realize that resistance training in particular has a lot of stigma that surrounds it about it making you ‘big and bulky’ or ‘muscle bound.’ That is all nonsense. Resistance training will make you better at any other skill so long as you continue said skill. 50 years ago many professional sports teams advise their athletes against doing resistance exercise. Now, every single one of those same organizations has hundreds of thousands, if not millions, of dollars devoted towards their resistance training programming. If you follow Layne and me, you know that we are big fans of resistance training. There are very few absolutes but we believe virtually anyone who doesn’t have a heavy labor job should be resistance training. Resistance training not only improves body composition, it reduces body fat setpoint, improves insulin sensitivity, cardiovascular disease risk, type 2 diabetes risk, mortality, bone mineral density, and so much more.4 5 3.

With regards to reverse dieting specifically, resistance training is extremely important. First off, it will increase energy expenditure and improve lean body mass which can help lower body fat setpoint and increase BMR.10 Greater LBM means more metabolically active tissue and greater energy expenditure per day. If you relate this to nutrition, it then gives you the added benefit of being able to consume more calories from food. Having greater energy expenditure and more metabolically active tissue are huge benefits for minimizing post diet body fat regain and fat gain in general. The goal is to raise our total TDEE, so resistance training will assist across multiple facets with this. From the calories you burn during your workout, to lowering your body fat setpoint, and from the LBM you accrue, if you aren’t resistance training, there is no better time than now to start and the rewards will be far reaching. Where to Start - Resistance Training If you haven’t been resistance training, a reverse diet is the perfect time to start for all the reasons we detailed in the previous paragraph. That said, there may be some unique challenges if you have just started resistance training due to the effect it may have on your body weight and how you manage your check ins during your reverse. You may end up gaining some weight, but not necessarily from body fat due to the nutrient partitioning effects of resistance training (directing nutrients towards building new muscle and away from fat) .

As we stated previously, if your weight is going up faster than the ‘allowable’ weight gain but you don’t look like you’ve gained fat looking at your pictures, your body fat measurements aren’t increasing, and your waist measurement isn’t going up, it’s likely that you haven’t gained fat and don’t need to delay taking an increase in calories for the next week. Most of you reading this book likely do not fall into this ‘newbie’ category however, as most of you discovered the joys of resistance training some time ago. For you, the advice is quite simple. If you are already on an effective resistance training program, there’s no reason to change. If you are on a proper training program then you are practicing the principles of progressive overload, effective volume, and periodization. Progressive overload is exactly what it sounds like. In order to get a muscle to adapt to a stressor you must impose stress on the muscle. When you first start weight lifting, the threshold for imposing a stress on your muscles was quite low. As you get stronger you become better at lifting those original loads to the point where it no longer stresses your muscles and you have to add more weight in order to continue to impose stress onto that muscle and force it to continue to adapt with more hypertrophy. This sort of ‘add more weight to the bar to keep making gains’ works for a while, but eventually your rate of strength gains will drastically slow and eventually stop. The Principles of Progressive Overload Just because your strength gains reaches the point of plateau, does NOT mean however, that you cannot impose more progressive overload. Progressive overload is just referring to overloading the muscle with a stressor and you can do that through multiple means. If you can’t lift more weight, you can add more effective volume. What is effective volume? Well quite simply, it’s the number of ‘hard sets’ that you perform per week. We say ‘hard sets’ because it’s unlikely that low effort sets create much of a stress on muscle tissue and thus don’t require the muscle to adapt. While there is some debate in the research community, the general consensus is that a set needs to be taken close to complete muscular failure (within ~5 reps) in order to be an effective set. On the repeti- TRAINING AND CARDIO 111 Hypertrophic Potential tions in reserve (RIR) scale this would be expressed as an RIR of 0-5. Before you jump at the chance to take a bunch of sets to complete muscular failure, you should realize that training consistently to failure will induce a lot of fatigue and be more likely to elicit overreaching, whereby the muscle is accumulating so much fatigue from performing the sets to failure that it cannot recover in time for the next exercise bout. Therefore, it may be prudent to perform most sets within the RIR 1-3 range (1-3 reps shy of failure) and only taking a few sparse sets to absolute failure here and there. Sets at RIR 1-3 are likely intense enough to elicit an adaptive response from the muscle (assuming enough total hard sets are performed) but not so fatiguing that their impair long term recovery and performance. 10 9 8 7 6 5 4 3 2 1 0 Reps in Reserve (RIR) Figure 8.1: Effective reps concept adpated from James Krieger of Weightology. Training closer to failure (0-5 RIR) is thought to provide increased training adaptations. TRAINING AND CARDIO 112 Another form of progressive overload is simply adding more hard sets of RIR 0-5 (mostly in the RIR 1-3 range) and using that as a method to force your muscles to adapt. That said, many of you will read this and immediately orchestrate some sort of resistance training program that involves 100 hard sets per week for each body part. We don’t recommend doing that at all. Increases in effective volume should be progressed appropriately. If you add in tons of volume before you are appropriately adapted you will simply overreach, burn out, and likely get sore, or worse, lead to injury. If you are still making strength gains, or adding more repetitions to your sets at the same weights then there is no reason to add more sets (unless you are doing that as part of a controlled, periodized program). Increases in effective volume need to be planned out correctly and should only be added after a relatively lengthy plateau. If you are plateaued on your strength and hypertrophy progress, first ask yourself the following questions: 1. Am I eating enough? If you have just finished a long 20 week diet and lost a good amount of weight, it’s probably not surprising that you haven’t added a ton of weight to the bar. In fact, it’s likely the opposite, you’ll have seen a decrease in strength as you near the end of your diet. This is another great reason to start a reverse diet, you are going to feel better eating more calories and hopefully perform better with your training. 2. Am I sleeping enough? This seems like obvious advice but many people who believe they have encountered a plateau are simply under-recovered from lack of sleep. Sleep deprivation, be it extended time falling asleep, frequent sleep disruption, or reduced total sleep duration has a sizable effect on decreasing strength and performance when it occurs over multiple nights.11 12 13 Further, less sleep when dieting led to greater loss of LBM and less loss of fat mass as well as greater hunger ratings 11. “Inadequate sleep and muscle strength: Implications for ... - NCBI.” 2 Feb. 2018, https:// www.ncbi.nlm.nih.gov/pubmed/29422383.

TRAINING AND CARDIO 113 through reductions to the hormone leptin and lower TDEE.14 15 16 Practice good bedtime habits, stop scrolling the gram, and get more sleep! 3. Am I truly training hard enough? We can’t tell you how many people tell us they train hard. They work up a good sweat and think that is sufficient to cause muscles to adapt. If you want your muscles to adapt you must CHALLENGE them. Some of you may have even thought that keeping sets at an RIR of 1-3 is too easy. We can tell you that if you think a set of RIR 2 on a compound lift is ‘easy’ then you’ve likely never truly taken a compound lift like a squat to complete muscular failure. If you are consistently training in an RIR 1-3 range it should be VERY difficult. Layne and I can both attest, we get nervous before we train because we know the effort required to achieve said RIR. 4. Am I doing TOO MUCH volume? Often times we see people not making progress who are already ahead of their adaptation curve. That is, they are already doing too much volume that their body can’t recover. Throwing more volume on top of this is not going to fix the problem and will likely make it worse. So how do you know if you are doing too much volume? You will likely feel beat up, with quite a few aches and pains, decreased motivation to train, decreased strength, decreased exercise performance, and you will likely feel pretty sore on a regular basis. If this is the case, it might be time to take a deload or a taper week in order to allow your body some active recovery. Then ease back into training at an effective volume that you can recover from. Layne and I both like to use a reactive type approach to training deloads. We plan for periods of progressive overload in order to build muscle, and we listen to our body cues. If a deload seems like the right thing then that’s what we’ll do. 5. Am I eating enough protein? If you are following the methods in this book the answer to this is likely a resounding ‘yes’ but if you aren’t, it could be 14. “Association between sleep duration, fat mass, lean ... - NCBI.” 21 Feb. 2017, https://www. ncbi.nlm.nih.gov/pubmed/28220551.

TRAINING AND CARDIO 114 impairing your recovery and is another factor to consider. 6. Am I under significant life stress? People don’t talk about this as much but if you are under a lot of stress that adds to your burden to recover from. Adding more training stress on top of general life stress is probably not the best idea. Better off focusing on resolving what you can from the life stress so that you can then move forward in your training. If you answered ‘no’ to all those questions then it may be time to increase your effective volume and do more hard sets. If you answered no to any of them you probably need to focus on those first before making adjustments to your training. As you reverse diet it is likely you will get stronger as you increase calories which means progressive overload will likely happen on it’s own for a good while before you ever plateau and need to increase volume. Should I Lift Heavy or Light Whether you choose to lift heavy weights for low reps or lighter weights for higher reps or a combination of both (they aren’t mutually exclusive you), it doesn’t appear that one is necessarily better than the other for building muscle. Indeed, studies comparing light weights (as low as 30% of an individual’s 1 rep maximum) to heavy weights seem to produce the same increases in muscle mass when sets are taken close to failure.17 18 Once again, this aligns with the concept of the ‘effective reps’ or ‘hard set’s’ model of effective training volume. That said, training with heavy weights (>80% of a 1RM) produces superior strength gains compared to volume equated lower intensity programs.19 If heavy training produces the same hypertrophy and greater strength gains, then why not just do all heavy training? There are a few reasons, the first being that heavy training tends to be more fatiguing on the central nervous system, 17. “Resistance exercise load does not determine training ... - NCBI.” 19 Apr. 2012, https://www. ncbi.nlm.nih.gov/pmc/articles/PMC3404827/.

TRAINING AND CARDIO 115 especially when performed with compound lifts such as the deadlift, squat and bench press. Further, in order to continue using heavy weights during subsequent sets, rest periods will need to be longer compared to using lighter loads for higher reps..This is likely why the optimal ‘hypertrophy rep range’ has typically been defined as 6-15 reps amongst ‘bro’ circles. Sure, you can do 50+ reps to near failure at 30% of your 1 RM, but that’s going to take a long time for each set. Likewise, just trying to accumulate volume by doing super heavy sets of singles and doubles will be centrally fatiguing and also require a lot of time between sets, as well as a possible increased injury risk. Keeping reps between 6-15 likely evolved as a standard in bodybuilding because it allows individuals to use heavy enough weights to reach fatigue relatively quickly during sets, but it wasn’t so heavy that they produced a ton of central fatigue. We aren’t saying to ONLY lift in the 6-15 rep range, we are just providing scientific rationale for what the bros might have known all along. If you want to lift in a rep range greater than this? Great, you can do so and still grow a lot of muscle. Want to lift heavy weights in a rep range lower than this? Great, you can do so and still grow a lot of muscle and get a lot stronger. You can also use a multitude of rep ranges to get the benefits of varied repetition schemes while simultaneously providing a training stimulus that is likely less boring due to increased variety. We like variety in nutrition and we certainly like variety for training as well. Regardless of how you choose to train, realize that it probably shouldn’t change just because you are reverse dieting, bulking, dieting for fat loss, etc. It should change as part of a properly constructed program that employs progressive overload appropriately. How Often Should I Train? This is another hotly debated topic in scientific circles. In general, it appears that the frequency of training is less important than the total amount of effective volume or hard sets that you do during a week. So could you go in one day per week and simply hammer your entire body for 8 hours and get the same gains as spreading this out over 4 sessions at 2 hours each spread over the course of a week? This is unlikely. The first reason is that performance will likely begin to decline as you become more centrally fatigued. Training a massive TRAINING AND CARDIO 116 amount for one day then having the rest of the week off might sound appealing to a lot of people, until they get through a few hard sets on a compound leg exercises and are now struggling to walk to their next exercise. Further, there is evidence that there is an ‘anabolic cap’ to set number for a body part in a workout, probably around 10-15 sets per body part per session, however the total anabolic set number has not yet been established as several studies have shown that up to 27-45 hard sets per week produces superior hypertrophy compared to lower set number per week.20 21 22 In order to maximize hypertrophy, it may be superior to perform multiple sessions per week, per body part, in order to better distribute volume. If you do 20 sets in a workout for example, you likely haven’t gotten superior gains compared to say 10-15 sets, but if you want to get to around 27-45 sets per week, you’d need to do multiple sessions of 10-15 sets per week. Your frequency of training will therefore be determined by your total set number for the week. Recommendations being that you should probably cap your daily volume at 10-15 sets per body part. Now before you go out and start doing 45 sets per week for each body part, keep in mind that these high volume recommendations are for advanced trainees. If you start out at 45 hard sets per body part per week you will easily overtrain and likely get injured. You should try to make progress on the minimum amount of hard sets you can per week for several reasons. 1. It will require less time in the gym. If you get to the point where you are doing 40+ hard sets per body part per week in the gym, you will likely be in the gym over 2 hours per day, virtually every day. The more sets you add the more opportunity there is for aches, pains, and possible injuries. 2. Even if you do make good progress on more volume than you need to progress, eventually you will plateau and need to add even MORE volume. Bet- 20. (2018, September 11).

The number of sets on each day is also going to vary depending on your training status. This is simply a guide to give you some ideas on how to split your training up. You should try different things out and figure out what works best for you. Keep in mind that your weekly effective training volume is the most important number to hit. After that you can worry about frequency and distribution of your number of hard sets. What About Cardio? Now here is where it gets fun. How much cardio you will perform during your reverse will depend on multiple factors including how much you were doing at the end of your diet (if you are starting a reverse diet after your fat loss diet), how aggressively you wish to reverse and recover your metabolic rate, and how much purposeful cardio you’d ideally like to include, as some people just simply enjoy this. Don’t get us wrong, we want you to be active and for your NEAT to increase, but that increase is a non-purposeful endogenous increase in activity. That is, as you increase your energy intake you should get spontaneously more active. We don’t mean that you’ll suddenly feel compelled to go run a marathon, what we mean is that you will likely start unconsciously moving more during the day, taking extra steps, fidgeting more, training harder, etc. This is one of the ways that reverse dieting likely increases your TDEE other than increasing your BMR through positive metabolic adaptation. So let’s get into it. Where do we start with cardio? Well if you’ve been doing zero purposeful cardio then congratulations, you don’t need to make any changes. You can continue doing zero cardio. If you have been doing purposeful cardio during a diet phase to facilitate weight loss, but you would now like to phase it out completely or down to a more manageable level, then we need to approach it the same way we would increasing calories, we need to cut it down in a slow and controlled manner. At what rate should we cut it? Great question, let’s examine what it looks like. TRAINING AND CARDIO 121 Conservative: If you stay within your allowable weight gain range (0.2% of total body weight per week) then you can reduce purposeful cardio by 2.5-7.5% duration. Since you are also increasing calories, we recommend staying towards the lower end of the cardio reduction range if you are taking the higher end of the caloric increase. If you take a more conservative increase in calories, then you can decrease cardio more aggressively. For example, if you decide to take the full 3% increase in calories, the upper calorie recommendation for a conservative reverse diet, then perhaps lean closer towards the 2.5-5% reduction in cardio duration. If you only take a 1-2% increase in calories, then perhaps drop cardio by 5-7.5%. Alternatively, if you decide you hate cardio and would rather reduce it faster compared to just increasing calories, you could take no calorie increase and reduce cardio duration by 10-15% in any given week. Moderate: If you stay within your allowable weight gain range (0.5% of total body weight per week) then you can reduce purposeful cardio duration by up to 7.5-15%. Since you are also increasing calories, we recommend staying towards the lower end of the cardio reduction range if you are taking the higher end of the caloric increase. If you take a more conservative increase in calories, then you can more aggressively decrease cardio duration. For example, if you decide to take the 5-6% increase in calories, perhaps lean closer towards the 7.5-10% reduction in cardio. If you only take a 3-4% increase in calories, then perhaps drop cardio by 12.5-15%%. Alternatively, if you decide you hate cardio and would rather reduce it faster compared to just increasing calories, you could take no calorie increase and reduce cardio by 20-27.5%. Aggressive: If you stay within your allowable weight gain range (0.8% of total body weight per week) then you can reduce purposeful cardio by 17.5-25%. Since you are also increasing calories, we recommend staying towards the lower end of the cardio reduction range if you are taking the higher end of the caloric increase. If you take a more conservative increase in calories, then you can more aggressively decrease cardio. For example, if you decide to take the full 8-9% increase in calories for a more aggressive reverse diet approach, perhaps lean closer towards the 17.5-20% reduction in cardio. If you only take a 6-7% increase in calories, then perhaps drop cardio by 22.5-25%. Alternatively, if you decide you hate cardio and would rather reduce it faster compared to just increasing calories, you could take no calorie increase and reduce cardio by 30-35%. TRAINING AND CARDIO 122 Now I’m sure you’ve probably gone ahead and done the math based on your own weekly cardio and you’re thinking it’s going to take you forever to remove your cardio. Keep in mind you have to use common sense with these percentages and not get dogmatic about them. If you are only doing 30 minutes of purposeful cardio per week and you want to get rid of it and you are on an aggressive reverse where you could take a 300 calorie increase but decide you are just going to cut out 30% of your cardio instead, you are only cutting out 9 minutes of cardio and NOT taking a 300 calorie increase, that is probably ridiculous. Instead we’d recommend simply cutting out the cardio completely if you want to and take a more modest increase in calories. These percentages are really only valid for people who are at least 100 minutes of purposeful cardio per week. For those of you who are below that number, but would like to slowly cut out your cardio, we would simply recommend cutting it out slowly over a 6-12 week period and just take more modest calorie increases, staying on the conservative side of your ranges. Another thing to consider, and this is where things become tricky, is the intensity of your cardio. If you are undertaking 100 + minutes per week of high intensity interval training, you are going to be expending a much greater amount of calories than you would if you were performing all your cardio in the form of low intensity steady state such as walking. So we also need to consider the likely energy expenditure of the cardio being performed. Let’s take a practical example, I’ll use myself (Holly speaking) to explain. I currently perform 6 resistance training sessions, 120 mins of cardio at a modest to high intensity in the form of a spin class or on the stairmaster, plus an additional 70 minutes of low intensity cardio in the form of walking. When I begin my reverse diet, I personally prefer to take a conservative approach to minimize body fat regain, however in the initial stages of the reverse diet I would much rather take a larger percentage decrease to my cardio to help free up my time, and a much smaller percentage increase in my calories. Once I have determined by new post show maintenance calories, I will forgo an initial calorie increase and instead reduce my cardio duration by the maximum recommended 15%, bringing my total time down to 160 minutes. So how do I know which modality of cardio to reduce first? Well it depends on how aggressive you want to be with your reverse diet and what you as an indi- TRAINING AND CARDIO 123 vidual values most. I personally opt to reduce my high intensity cardio first as this more physically and mentaly fatiguing, and after a long drawn out competition season, I am all about getting back to a place of balance. Furthermore, we know that high intensity training can impede recovery from resistance training, so this is another reason why I would personally prefer to reduce my high intensity cardio to help my body recover better from workouts, and hopefully result in less muscle soreness, something that becomes increasingly more notable towards the end of prep. On the contrary, many of you may place greater value on overall time and would prefer to reduce your cardio in the form that gives you back the most amount of time. For you, reducing your cardio in the from of 70 mins of walking might be the preferred option, as you’re getting back 70 minutes of time rather than 30 minutes. Now I mentioned earlier that the intensity makes a difference, so consider this. In theory, if all your cardio was in the form of lower intensity steady state, you could potentially afford to reduce your cardio by double the amount of the percentages listed. For example, 120 minutes of moderate to high intensity cardio on the stair master yields ~1600 calories using my Apple Watch as a measuring tool, while 70 minutes of low intensity walking yields a much lower ~ 400 kcals. Now before you jump out of your seat and tell me these are inaccurate, yes, I realize an Apple Watch has its limitations, like any tool that uses equations. No matter how inaccurate these values may be in absolute terms however, they are likely going to be relative for me if I am exercising at a set intensity and tracking them on a consistent basis. I wanted to increase my weekly energy balance by 533 kcals from cardio (76 kcals per day), I could do this by removing 40 minutes of my moderate to high intensity cardio. For example, 533 kcals / 1600 kcals = 0.33. (33%) x 120 mins = 40 mins. I could also remove 100% of my low intensity walking, since this accrues 400 kcals and have 133 kcals remaining. I could then remove a further 10 minutes of moderate to high intensity cardio. 133 kcals / 1600 kcals = 0.08. (8%) X 120 mins = 9.9 mins (rounded to 10). TRAINING AND CARDIO 124 Purposeful Cardio - A More Accurate/Simple Approach? Over the last 5 years, step counting has become much more popular, partly because of the emphasis on the importance of NEAT in the evidence based community and partly because of the availability of smart watches and devices that making tracking them conveniently. Now don’t get us wrong, you don’t want to rely on the watch to tell you what your daily energy expenditure and exercise expenditure is, as they have been shown to be inaccurate.26 The good news is, these watches do appear to be accurate for measuring step counts! Therefore, we can get a relatively accurate assessment of part of our TDEE. For those of you who have been doing purposeful cardio and tracking your step counts, you could simply decide what the minimum number of steps per day you’d like to get to and work back from there. For example, if you are doing 15,000+ steps per day during your diet but you are also doing over an hour of purposeful cardio per day and you would like to reduce that to a more manageable level or perhaps nothing, you’d simply need to determine how many steps you do when you are performing cardio and subtract those from your daily step count to give yourself a target. For example, if your hour of cardio requires 9000 steps and you are averaging 15000 steps per and you want to get it down to 9000 steps per day total, then you are looking at reducing 6000 steps out of your day. You can still use the percentage reductions from earlier to reduce your step counts. For example, if you were on a conservative reverse and you were within your allowable weight gain and decided to make a 5% reduction in your cardio steps, that’s 300 steps you’d reduce. So your minimum would go from 15000 steps per day to 14700 steps per day. Why do we say a minimum? As you increase calories you may find that your step count starts to go up because you have more energy and your body begins to move more in order to dissipate energy. In fact you may find that you can cut more cardio out than you thought because you are getting such a spontaneous increase in movement. For example, those 300 steps may only equated to a few minutes of walking on the treadmill, but you find that you are consistently going over 15000 steps anyway 26. (2018, April 12). Evaluating the Validity of Current Mainstream ... - NCBI. Retrieved November 27, 2019, from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5920198/ TRAINING AND CARDIO 125 even though you reduced your purposeful cardio. If you are, that means you can actually reduce it further. We do want to make sure we hit our minimum step counts, however. The reason being that we don’t want to be dropping energy expenditure too quickly. That’s why we call it a minimum. Once you have reduced your steps counts down to a level that you find is sustainable for you and that you enjoy, then you simply keep it there and make sure you hit that, but you don’t limit yourself from doing more. For example, let’s say that your goal was to eventually get to 9000 steps per day but even after cutting out all of your cardio you find that you are doing well over 9000 steps per day, that is perfectly fine! In fact it’s actually excellent because it means that your NEAT is going way up because you are doing a lot of non-purposeful movement and energy expenditure. What we want to avoid is dropping below those minimum step counts as we know that some people don’t increase spontaneous energy expenditure during overfeeding as much as others. Therefore in order for some of you to hit your step counts, you may need to do more purposeful exercise. For example, I (Layne here) average nearly 9000 steps per day with zero purposeful cardio. On the occasion that I am extremely sedentary for the day and I’m significantly below that, I might add in a stroll around the neighborhood to make sure I hit my minimum, but typically I don’t have to. I (Holly here), on the other hand, only average about 3000-4000 steps per day without purposeful cardio and for me to keep my calories at a more ‘fun’ level during the offseason I will typically add in cardio to get around 8000-9000 steps per day. Therefore, when I’m reverse dieting, my goal is to get myself down to about 8000 steps per day by slowly reducing my purposeful cardio and then I maintain it at an 8000 step minimum for the duration of my reverse diet. Don’t ‘Cheat’ Reverse Dieting We aren’t referring to ‘cheat’ meals here. Rather we are referring to purposefully doing excessive exercise so that you can simply eat more calories. While it’s not the worst thing in the world to have high activity, it should not feel forced. You should be on an effective resistance training program, and any cardio on top of that should be what you enjoy (eventually, with the caveat that if you ended a diet on very high cardio, it may take some time to bring it back down to a normal TRAINING AND CARDIO 126 sustainable level). Remember, the goal is to enhance your endogenous energy expenditure. That is we want to raise your BMR and NEAT. If you are doing an extra 2 hours per day purposefully walking, that isn’t NEAT, that’s just exercise. At that point you are just trading extra purposeful energy expenditure for more calories, which you can do to a certain extent, but the goal of reverse dieting is not to have to exercise your way to more calories. If you become spontaneously more active due to increased calories that is fabulous, but we don’t want to force it because then it no longer falls under the endogenous category and is now just extra exercise. Summary Exercise should be an integral part of any good reverse diet. If you are already on an effective resistance training regiment then there is no need to do anything crazy or different just based on reverse dieting. Simply continue the good principles of progressive overload with appropriate volume and frequency for your training status. If you are doing purposeful cardio and wish to reduce it, you can do so by reducing it slowly over time as you increase your calories in a controlled manner over time. If you track steps it may be a more accurate way to standardize your energy expenditure. You should hit your step count minimums but if you become spontaneously more active there is no reason to limit your steps to the minimum, especially if you are doing an amount of cardio that you enjoy or you are doing no purposeful cardio at all. 9 127 ENDING A REVERSE DIET AND BEGINNING A NEW FAT LOSS PHASE A fter reading the previous chapters you have been armed with the knowledge to understand, construct, and execute your own reverse diet. However, this chapter is where the rubber truly meets the road. Many people start reverse diets with good intentions only to derail them by cutting too soon before they are truly ready to do so. Whether it’s a mini-cut of a few weeks or a full blown cut of several months, we need to make sure that you are in a good place to begin another fat loss phase. We want to be very clear about starting another fat loss phase BEFORE you are truly ready, it is the best way to fuck up a decent reverse diet. We’ve seen so many people beg us to ‘just do a short mini cut’ or ‘just get 5-10 lbs off real fast’ and then they try it and hardly lose anything and set their reverse diet back by quite a lot. In order for you to be ready to enter into a fat loss phase, there need to be 3 basic principles satisfied: 1. You need to be mentally ready to enter into a fat loss phase, meaning you are in a good place with your relationship with food and you are excited to enter a fat loss phase, not dreading it. 2. You are going to take the fat loss phase seriously. This isn’t the time to fuck around. If you can’t commit to going hard in a fat loss phase then it isn’t the time to do it. Better to wait until you can truly commit to it while continuing to reverse and improve your metabolism 3. You need to be physically ready to enter a fat loss phase How Do I Know if I’m Physically Ready for a Fat Loss Phase? This is the question we get most often regarding ending a reverse diet. “How do I know when I’m ready?” The easiest way to determine this is simple; do your ACTUAL current maintenance calories at least match your predicted maintenance calories? Meaning that if we plug your metrics into the Müller or similar equation and apply the appropriate activity factor, how does that number compare to your current maintenance calories? If your current maintenance ENDING A REVERSE DIET 128 calories are the same or greater, then it could be time to consider a fat loss phase. If your current maintenance calories are less than your predicted maintenance calories however, don’t even think about it. Full stop, end of story. In reality your current maintenance should actually be about 5-10% greater than your predicted maintenance. The reasoning for this goes back to our theory of maintenance calorie ranges and metabolic adaptation. It’s quite likely that you are sitting on the upper end of your maintenance calories if you are a good ways into a reverse diet. For example, if you are currently maintaining your body weight on 2100 calories and your predicted maintenance is 2050, you might be thinking that you are free and clear, but that may not be the case. If your maintenance calorie range was 220 calories from low end to high end for example, that means the median (middle) would put you at or just under 2000 calories. In this situation we would encourage someone to at least get up to 2200 or 2300 calories and be maintaining their weight before we encourage them to enter into a fat loss phase. We have simplified this into a quick and dirty reference table to determine if you are at a ‘normal’ level. Please keep in mind this table is not nearly as precise as something like the Müller equation or the Aragon formula so it is simply to be used as a quick rough estimate guide. We still recommend making a more precise calculation before determining that you are back up to a normal maintenance calorie range. Calorie Ranges Maintenance Calorie Ranges for people with an Activity Factor < 1.5 Age 18 - 40 / kg LBM Age 40 - 60 / kg LBM Below Normal 25 -35 22 -32 Normal 35 -45 32 - 42 Above Normal 45 - 55 42 - 52 ENDING A REVERSE DIET 129 Maintenance Calorie Ranges for People with an Activity Factor > 1.5 Age 18 - 40 / kg LBM Age 40 - 60 / kg LBM Below Normal 28 - 38 25 - 35 Normal 38 - 48 35 - 45 Above Normal 48 - 58 45 - 55 Table 9.1: Approximate maintenance calorie ranges for people with different activity levels based on LBM. These have been separated into low, normal, and above normal. This also gets into the question of staying at maintenance for a period of time post reverse/pre-fat loss phase. Several individuals have recommended spending the end of a reverse diet simply staying at maintenance for several weeks or months. Typically what we have seen recommended is spending the same amount of time at maintenance as you do in a reverse diet. We don’t think that’s necessarily a bad idea but the numbers seem a bit arbitrary. We think this strategy probably works best for individuals in specific circumstances where they have reached the absolute limit of what they are willing to accept in terms of fat gain, but they also have a long history of dieting and probably need to spend more time out of a deficit before entering a fat loss phase. For these individuals, spending time at maintenance might make sense at the end of a reverse diet. There is nothing magical about staying at maintenance however, some people have made it seem like if you don’t spend as much time at maintenance as you did in a reverse, the entire thing will be ineffective. That is very unlikely, especially if you’ve managed to raise your maintenance calories significantly above your predicted maintenance calories. For example, if someone is humming along and increasing their calories pretty much every week with really minimal weight gain and their actual maintenance is well above their predicted maintenance after 20 weeks of reverse dieting, do they then need to spend another 20 weeks at maintenance if they’d like to do a cut? NO. They can simply continue reverse dieting until they are ready to do a fat loss phase. However, if ENDING A REVERSE DIET 130 you are at a caloric level that is at or beyond your predicted TDEE and you really don’t want to possibly gain any more weight but you want to give the reverse a longer period of time then holding steady for a few weeks or months at maintenance is perfectly fine, but realize that if you’ve done a long enough reverse and your TDEE is high enough, holding at maintenance calories for a certain duration isn’t necessary. How Long Should a Reverse Diet Be? This is a tough one to answer because we simply have almost zero data on this. What we will say is that it should likely be proportionate to the magnitude and duration of the energy deficit you are coming out of. That is, if you just did a moderate 12 week cut and lost 5 kg, you probably should spend at least 12 weeks reverse dieting before you think about another at loss phase, assuming that at the end of 12 weeks your actual maintenance calories are greater than your predicted maintenance calories. If you are someone who has been yo-yo dieting for years then this may require much more patience on your part during this process. You’ve spent a long period of time beating the crap out of your body and metabolism while you consistently activated your body’s self defense system without long periods of sustained, controlled, overfeeding, so it’s probably going to take a good period of time staying out of a deficit to undo some of those metabolic adaptations. For many of you, the concept of taking a step back so that you can move forward is probably going to be very difficult. For those of you who have been wrapped in ‘diet culture’ and have felt like you have been perpetually on a diet and moreover, felt the need to be perpetually on a diet, it might be absolutely terrifying to consider the idea of increasing calories if you still have more fat you want to lose. Consider this however, what you have been doing thus far and the behaviors you have adopted have taken you to where you are now. You will continue to get the same results if you continue the same behaviors. If you want a different outcome, then you have to do something different. If you’ve been yo-yo dieting for years, now is the time to BREAK THE CYCLE. It’s going to be difficult and scary as those of you fully immersed in diet culture may feel some comfort in being able to say you are on a diet. It may not be as comfortable to say ‘I’m work- ENDING A REVERSE DIET 131 ing on increasing my calories so I can improve my energy expenditure.’ Consider reverse dieting an investment. When you make a monetary investment you are taking money away from short term reward purchases with the understanding that one day that investment will pay off in more overall money in the long term. Investing in a solid reverse diet is investing in a metabolism that will allow you to lose more fat in the long run. That is the goal. We have seen so many people over the years who simply could not get out of their own way. They would ‘commit’ to a reverse diet for a few weeks and at the first sign of gaining any weight they would panic and try to diet again with the same results, rather lack of results. If this sounds like you, write this down and repeat it to yourself: If you do what you have always done, you will get what you have always gotten! Ending The Reverse Ok, you’ve done it. You slowly added calories and raised your TDEE to a solid level. If you are happy with your current body fat then CONGRATULATIONS, you’ve done it! Just chill here and be happy! You might have some minor weight fluctuations here and there and maybe even a small amount of fat gain during holidays or events but nothing that can’t be fixed by a short mini-cut. If you went through a proper reverse, gave it enough time, got your TDEE up to a good level and you are ready to enter into another fat loss phase because you aren’t quite at your body fat goal yet, then there are some things you should know. First off, don’t do what we see quite a few people do, which is YOLO (you’re only lean once)1 the end of your reverse by eating whatever the hell you want because you know there is a fat loss phase coming up and you might as well have all the foods you want. If you have done a proper reverse and your TDEE is high enough, you should be able to fit many of those foods into a reasonable diet if you plan things out correctly so you don’t need to binge on them at the end of a reverse. Remember that if you gain quite a bit of fat at the end of a reverse it’s just more fat that you have to take off during the fat loss phase. Why make things more difficult for yourself? Stay the course and treat the end of your reverse like the rest of the reverse. 1. (n.d.). YOLO Shirt – BioLayne Store. Retrieved November 29, 2019, from https://biolaynestore. com/products/yolo-shirt ENDING A REVERSE DIET 132 Second, don’t try to reverse diet in the opposite direction for fat loss. For some reason we see many people think this is a good idea, it’s not. The entire point of increasing calories in a controlled manner is to limit fat gain while slowly adding calories so that your body’s endogenous TDEE has a chance to keep pace with your calorie increases. If you attempt to do that for fat loss what will happen is very similar to what happened on the reverse, you will slowly decrease calories and your body will simply decrease your TDEE proportionately and your weight loss will be minimal. Remember that based on our theory of a maintenance calorie range, it’s important to create a big enough initial drop to get you out of that maintenance range buffer zone. For this reason, we recommend at minimum a 20% reduction in calories from the end of your reverse. We have seen too many people try to do a small calorie reduction from the end of their reverse to transition into fat loss only to see them lose absolutely nothing. Consider the following: If someone finishes their reverse diet at 2400 calories and they have a 10% maintenance range, they are likely sitting at the upper end of their maintenance calories already with a range of ~240 calories for their maintenance range. If they try to make a 200-250 kcal reduction in calories it is likely that they won’t lose hardly anything. Whereas if they dropped by 20%, that’s a reduction of 480 calories and should be sufficient to get them outside their maintenance range. Please keep in mind that this is simply an example, we have observed people who could get away with being less aggressive and people who needed to be more aggressive. It’s important to keep data on yourself and have an idea of what kind of individual you are more likely to be based on your progressions. Preventing Unintentional Declines in Energy Expenditure It’s not just a buffering maintenance range that can frustrate people when they first stop trying to drop weight after a reverse diet. Many people get spontaneously less active without even realizing it. They fidget less, don’t train quite as hard, and don’t take as many steps during the day. I have personally tested this on myself (Layne speaking here) and I will spontaneously drop from around 9500-10000 steps per day while overfeeding to around 8000-8500 just from going into a deficit. One of our BioLayne coaches (Noah Lee) had a client who ENDING A REVERSE DIET 133 spontaneously dropped from 8000 steps per day during her reverse to around 4300 within ONE WEEK of a deficit! This is what is what often confuses people who oppose the concept of ‘calories in vs. calories out’ (CICO). They will say things like “I ate in a calorie deficit and didn’t lose weight.” What they don’t understand is while they ate in what SHOULD have been a caloric deficit, they unconsciously decreased their energy expenditure. This is why we think step tracking can be so helpful. If you know what your average steps are during your reverse diet, you can simply set a target to match them when you begin your reverse. This means that you may get to the end of the day and need to add in some purposeful walks in order to reach your step goal for the day and that’s fine. We wouldn’t necessarily recommend adding in a bunch of purposeful cardio at the beginning of a fat loss phase, but a good goal is to simply maintain your current resistance exercise volume and your daily steps. If you are truly maintaining your weight at the end of a reverse and drop your calories by at least 20% and maintain your steps, you should see some nice progress initially. This book is not a fat loss book so we won’t go further in depth in terms of setting up a fat loss diet, if you want more information on the ins and outs of setting up an optimal fat loss program, we recommend checking out Fat Loss Forever, in our opinion, the single greatest fat loss resource ever created (ok we are biased but we wouldn’t promote it if we didn’t believe in it). If you would rather not buy another book, that’s ok, we get it. In that case we’d recommend checking out our YouTube series on how to set up fat loss diets.2 3 One thing we would caution against is the expectation of enormous changes in the amount of calories you will be able to diet on after one reverse. We do typically see people improve in terms of being able to diet on more calories after reverse dieting, but they aren’t huge improvements typically, but if you reverse properly multiple times and diet properly as well, we do see people getting to levels of leanness they previously attained at >100 calories greater than pre2.

We’ve also seen people who have been able to get to levels of leanness that they were not previously able to attain after having gone through a proper reverse diet. Keep in mind also that the more times you properly diet and reverse diet, the better your results will likely be. For example, let’s take someone who starts a diet at 20% body fat and diets to 10% body fat. In the process they go from maintenance calories of 2300 to 1900. Then they reverse diet and go up to 17% body fat, but are maintaining on 2350 calories. That is a net improvement because even though their maintenance calories are similar to previous, they are leaner now. Then the next time they diet they are able to get to 9% going from maintenance calories of 2350 to 1900. Then they reverse diet again and get up to 2400 calorie maintenance but at 15% body fat. Then they go through another fat loss phase to get to 8% body fat and are able to get there with their end diet maintenance being around 1900. Each time they are getting progressively better. Keep in mind, this example would likely be taking place over the course of YEARS. That’s right, we are sorry to say that reverse dieting and proper fat loss phases take time. There is no quick fix, especially for those of you with long diet histories of yo-yo dieting. If you are tenacious, consistent, and persistent however, you can make huge improvements. Or maybe they just reverse back up to the same weight as previous, but on more calories and then diet down to the same body fat, but on more calories each time, those would also be examples of improvements. Since some of you are more visual, we’ve turned the previous example into a table. Phase of diet End of Reverse/Beginning of Fat Loss Maintenance Calories/Body Fat % End of Fat Loss/Start of Reverse Maintenance Calories/Body Fat % 1 2300 kcal/20% BF 1900 kcal/10% BF 2 2350 kcal/17% BF 1900 kcal/9% BF 3 2400 kcal/15% BF 1900 kcal/8% BF Table 9.2: Hypothetical person undergoing 3 fat loss and reverse diet phases and the corresponding changes in maintenance calories and body fat. ENDING A REVERSE DIET 135 This example also highlights how you don’t need to necessarily be perfect in keeping weight off in order to have a successful reverse. Sometimes when people gain any weight back after a fat loss phase and feel like they’ve failed, but that’s not necessarily true. Obviously we want to avoid massive fat regain in the initial phases of the post fat loss phase because there is increased risk of regaining large amounts of body fat and possibly adding more fat cells, but as long as you don’t go crazy binge eating after your diet for days at a time, you will likely be fine. If you are consistent with your reverse and COMMIT to the process, even if you do gain some weight back, this will likely be offset by the increases in your TDEE from controlled overfeeding over time. This period of sustained time in reverse diets will also dampen the body’s ‘self defense system’ since you will essentially be sending a signal that food is no longer scarce and the body can afford to be a bit more ‘wasteful’ with calories. Summary Remember, reverse dieting isn’t magical and if you have expectations of magical results you will be disappointed, but that is the case for any dietary strategy. Rather, if you work hard, are committed, consistent, and reverse properly, you will likely see significant benefits. Make sure you reverse long enough and get your TDEE at LEAST back to your predicted maintenance calories before you decide to initiate another fat loss phase. You should also make sure that you are in the right mental space to execute another fat loss phase as well before you commit to it. 10 136 REVERSE DIETING FAQ S ince reverse dieting is a new (within the last decade) concept, people have many questions. We don’t have all the answers, but we will do our best to clear up some of the myths and misconceptions in this chapter. Alternatively, if you have any questions we don’t cover, feel free to ask us on social media or you can ask us in the Team BioLayne Facebook page.1 Now onto the FAQ “How do I know whether I should reverse diet or try to lose fat?” Chapter 9 addresses this question in a roundabout way but we will take it more head on here. If you are someone who is not comfortable with your current body fat and your energy expenditure is good and your maintenance calorie level is reasonable (that is, at or greater than your predicted maintenance calorie level) then by all means do a fat loss phase. If you have more fat than you’d like but you feel like you are spinning your wheels, your calories are unsustainably low, your energy is constantly low, you feel lethargic, unmotivated, and are really having a hard time adhering to fat loss calories, then a reverse diet might be the best option for you to raise your energy expenditure and maintenance calorie level so that in the future you can more effectively lose fat on more sustainable calorie levels. “Someone said reverse dieting is BS and not science based, is this true?” It would depend upon the context of the claim of reverse dieting. Are there any scientific studies specifically done on reverse dieting? No, not specifically. There are some overfeeding studies that we have drawn 1. (n.d.).

Retrieved November 30, 2019, from https://www.facebook.com/groups/335868740332383/ REVERSE DIETING FAQ 137 data from, but we’ve also never claimed that. We have based much of our recommendations on what we’ve done with coaching over 2000 clients in the past decade between the two of us. We have absolutely seen people run the gamut of results from those who are able to significantly increase their calories while maintaining or even losing weight to those who do gain some weight during a reverse. “Aren’t you claiming that people can violate the laws of thermodynamics (calories in vs. calories out) if they are adding calories and losing weight?” Of course not. Energy balance always applies, but as we have stated many times, calories in vs. calories out are not independent variables. Calories in affects calories out. What must be happening in these particular cases of people adding calories and losing weight is the increase in calories causes an increase in energy expenditure that is disproportionately greater than the calories that were added, thus producing weight loss. Even researchers have observed this in individual subjects during overfeeding studies.2 “I put on a lot of weight after I finished my fat loss phase and now I’m having trouble losing it again, is my metabolism damaged or broken?” No, your metabolism isn’t broken or damaged. This arises from a video series I (Layne here) started in 2013 that was a series of videos with “Metabolic Damage” in the title.3 I regret using that term. The reason I used that term was it was the popular term at the time to describe the symptoms that people were reporting of rapid weight gain post diet and the inability to drop body fat despite eating in what should be a caloric defi2.

Retrieved November 30, 2019, from https://www.biolayne.com/media/media-search-results/?media=metabolic+damage REVERSE DIETING FAQ 138 cit. No matter how many times that I said it wasn’t really ‘damage,’ that title stuck with me for a long time. No, your metabolism isn’t damaged. Now, you may have a history of yo-yo dieting that has produced a situation where you are at a higher body fat than you would like and have low energy expenditure, but you are not resistant to weight loss, it may just be much more difficult for you due to low energy expenditure. “How do I know if I need to reverse diet?” No one ‘needs’ to reverse diet. In chapter 4 we described the different populations who may benefit from reverse dieting but no one ‘needs’ to do it. Anyone who would like to increase their calories while limiting fat gain could benefit from reverse dieting, but your specific scenario will dictate if, when, and how you implement it. “If I do a 2 week mini-cut, do I need to reverse diet?” As we stated previously, no one ‘needs’ to reverse diet. In general, we don’t feel a reverse diet is really that necessary for short deficits unless they are extremely severe. If you do a 2-4 week moderate deficit, when you are finished it’s probably fine to go back to your previous maintenance or perhaps slightly lower if you want to be on the safe side. “I’ve been reverse dieting for a few weeks and I’m hungrier now than when I was in a fat loss phase eating fewer calories. Is this normal?” We have definitely seen this in clients and experienced it at times ourselves. We think this is probably due to both physiological and psychological reasons. If you are adding calories and energy expenditure is going up, then it’s normal that you might start feeling hungrier, especially if energy expenditure is going up disproportionate to the increase in calories. We also don’t want to understate the psychological aspect of things. When you are dieting and focussed on an end goal, sometimes REVERSE DIETING FAQ 139 the drive to that goal may override some of the desire to eat. Once you are ‘finished’ with the fat loss phase however, many people suddenly feel compelled to eat like they never had before. This is why it’s so important to practice mindfulness and good habits in the post diet period. “Isn’t a reverse diet just a lean bulk?” Kind of, depending on the reverse diet you use (conservative, moderate, aggressive). The difference is in the check ins. On a ‘lean bulk’ you are making small increases in calories with the goal of gaining weight but a controlled amount. On a reverse diet, the goal isn’t to necessarily gain weight, rather there is a maximum allowable weekly weight gain. Therein lies the difference. “After a cut, shouldn’t I just go straight to maintenance calories?” It depends on which maintenance we are talking about. If you are referring to your ACTUAL maintenance at that time where you will maintain your body weight, then absolutely, that should be your minimum. If we are talking about your ‘predicted’ maintenance or your pre-fat loss phase maintenance then that’s another argument entirely. Remember that as we lose fat our BMR and NEAT drop significantly, so your ‘old’ maintenance will no longer be your real maintenance at the end of a fat loss phase. You can go straight back to that if you want, but you would need to be ok with more fat gain. “Can I still reverse diet if I gained more weight than I wanted to post diet or is it too late?” Sure, reverse dieting can still be effective for improving your energy expenditure. It’s not like a reverse diet only works in a ‘post diet’ state. Increasing your energy intake in a controlled manner will increase your energy expenditure regardless of whether you are in a post diet/lean set- REVERSE DIETING FAQ 140 ting or not. That said, it depends on if you are ok with your current body composition, but if you regained this weight quickly, we would recommend at least staying at maintenance or reverse dieting for a reasonable amount of time before attempting another fat loss phase. “Why should I reverse diet to a certain caloric intake? Why shouldn’t I just jump straight there? What is the difference?” The difference is reverse dieting gives your metabolic rate enough time to adapt to controlled calorie increases so that you get to that same calorie intake with much less body fat gain, albeit a slower process to get to that calorie intake. Slow, controlled increases in calories are often adapted for and compensated for by proportionate or disproportionate increases in energy expenditure. For example, in one study, overfeeding by 20% above maintenance calories did NOT increase fat gain, but overfeeding by 40% and 60% produced significantly more fat gain, way disproportionate compared to the 20% increase.4 This also adds strength to our concept of a maintenance range of calories. “Should I be losing weight during a reverse diet?” We don’t expect weight loss, but we do see it in various cases. If it occurs it is likely due to an increase in NEAT or BMR increasing your total energy expenditure in excess of the increase in calories. We wouldn’t say this is rare, but it’s also not the majority of people. If it does happen, you can either be more aggressive with your caloric increases to get your calories up more quickly since your energy expenditure is going up, or you can continue to increase slowly and enjoy the weight loss but raise calories more slowly. 4.

Retrieved December 1, 2019, from https://www.ncbi.nlm.nih.gov/pubmed/18042669 REVERSE DIETING FAQ 141 “What if I am reverse dieting and gain weight but my calories are still low?” It depends on how much weight you gained. If it’s within the allowable range of the reverse diet that you’ve selected, continue the course as planned. If it’s more than the allowable weight gain, do not increase calories until it stabilizes and then continue. Also try not to get freaked out by short term rises and falls in weight as they are often due to fluid shifts rather than fat gain if it’s a fast change in weight. “Can I increase my protein? Or just my carbohydrates and fats?” This boils down to personal preference. There is no need to increase your protein if you are already consuming enough, but there are a few instances where it might make sense. If you are starting a reverse diet and still very hungry, it may make sense to increase some of your calories from protein as well as carbs and fats. Also, if you’ve been able to get your calories up very high after a long reverse diet, you may reach a point where your carbs and fats are so high you might just like some more protein as personal preference to balance your diet, this is also fine. We’ve had people who were maintaining their body weight on over 500g of carbohydrates and over 100g fats per day but were under 200g protein and would request more protein just to have a bit more balance. 11 142 CONCLUSION AND CASE STUDIES T hank you for reading our book. We hope that you have a good grasp of what reverse dieting is and what it is not. We do not want you to think that reverse dieting is some kind of magic fix. It’s not. It is a useful tool that we have seen people make good progress with when implemented appropriately as part of an overall long term focused strategy. Sadly, we see many people make false claims about reverse dieting, either to sell their own reverse dieting materials or as an attempt to completely discredit it. We are fully aware and acknowledge that there are no specific studies on reverse dieting. That is absolutely a shortcoming but hopefully there will be more data coming in the future. Fortunately, we do have some data on overfeeding that seems to line up with some of the hypotheses we have proposed. This wasn’t an easy book to write for us. As scientists, we are discouraged from making strong claims when there isn’t appropriate empirical evidence. As such we tried to make sure we were responsible with how we spoke regarding reverse dieting and that much of what we spoke about was from the perspective of case studies with our own clients. As such, we thought it might be pertinent to include data we have gleaned from clients over the years. We have included a large body of data as well as selected case studies to highlight differential responses to reverse dieting so that you may better understand why you respond the way you do during this process. The first thing we have done is show you data from 55 clients from the last 18 months who have worked with us on reverse dieting. These clients fit our inclusion criteria: 1. Needed to have worked with us in the last 12 months (this is approximately how long we have been using our most current methodology and system for reverse dieting) 2. Must have reverse dieted for a minimum of 8 weeks 3. Must have been compliance level of at least 97%. Meaning of their target calories they were given, they must have been within 3% of those calo- CONCLUSION AND CASE STUDIES 143 ries. So if their calorie level on a given week was 2000, they must have been within 60 calories (1940 - 2060). As we discussed earlier, tracking errors can occur but we educate our clients in depth on this and try to make sure that it is minimized. 4. None of the clients were on an aggressive reverse. The vast majority were on a conservative reverse 5. While not inclusion criteria, it’s worth noting that of the 55 subjects, only 4 were men and 51 were women. Additionally, 1 subject is entered 3 times as she underwent 3 reverse diets during the period assessed, and another client was used twice as she underwent 2 reverse diets during that time. All data was tested for outliers with regards to weight change and increase in calories and no outliers were identified. 6. All subjects resistance trained. Most of them did some form of cardiovascular exercise as well. However, we did not increase their cardiovascular exercise and in fact, we decreased it progressively in the majority of subjects. ● ● ● ● ● ● ● Their average starting calories were 1493 calories per day. Their average starting body weights were 64.5 kg. We sadly didn’t have enough body fat measures to include that data. The average length of reverse diets was 16.1 weeks. Their average ending calories were 2220 calories per day Their average ending body weights were 66.1 kg. That means on average they increased their calories by 727 calories per day Their body weight only increased on average by 1.6 kg. We ran various statistical analysis on the data but probably the one that is most worth reporting is the test of a Pearson Correlation Coefficient. This test examines whether or not two variables have a significant relationship with each other. We compared the increase in calories during the reverse diet to the change in weight amongst our 55 subjects undergoing reverse diets. We returned an r=0.051 with a p value of 0.714. This means that it is highly unlikely that these two variables were associated with each other. For reference, a perfect association is an r=1.0. That is, as you increase one variable, the other increases in exactly the same proportion. A large correlation coefficient is considered to be greater than an r>0.50, a moderate r=0.30-0.49, and an r<0.29 is considered a small correlation. The r val- CONCLUSION AND CASE STUDIES 144 ue for calories increased vs. weight increase was 0.051 which is extremely small, indicating that it is highly unlikely the increase in calories was predictive of the change in weight. Further, the p value was very large, confirming that it is very unlikely that the extremely small correlation was statistically significant. If calories in versus calories out were independent variables you would expect to see a good correlation between calories in vs. weight gain. We did not observe that. What that means is it appears we were able to increase their calories quite disproportionate to any small gain in weight on average. But weight and calories are different units and perhaps we aren’t examining it the right way. That is weight is ultimately smaller in units compared to something like calories, so comparing the absolute change may not tell the whole story (nevermind that running a pearson correlation actually corrects for this)? So we re-analyzed the data looking at the percent change of body weight vs. the percent change in calories. On average, our subjects increased their calories by 50.5% over their starting calories. Their body weight however, only increased by 2.7%. Just based on the eyeball test, by increasing calories in a controlled manner, it appeared we were able to avoid large increases in body weight, but were still able to increase TDEE by a large amount. kcal Intake PERCENT INCREASE Body Weight TIME Figure 11.1: Calorie intake and corresponding body weight values from reverse dieting. CONCLUSION AND CASE STUDIES 145 Just to provide perspective on the range of responses, the largest increase in body weight amongst all subjects was a 12.3% increase in body weight over a 20 week reverse diet. This was actually my (Holly here) reverse and it’s important to note that of the weight I gained (7.5 kg), The largest decrease in weight was a -4.75% decrease in body weight over a 14 week reverse and this person actually increased their caloric intake by 80% during that time! The largest increase in calories was in a subject who increased their caloric intake by 92.6% over 14 weeks and their body weight only increased by 0.57%! This person also had the largest weekly average increase in calories of 6.6% increase in calories per week. The smallest increase in calories was 9.4% over 11 weeks and this person gained 3.7% in body weight. We have shown these extremes to demonstrate that while averages may predict what will happen over a range of data, individuals may respond differently. Now, it’s possible that they just gained so little weight because we added in calories very slowly. However, if we had added 726 kcal right away when they started with us, we suspect the weight gain would have been significantly greater over time as the body’s energy dissipation systems would not have been given time to gradually adapt and it’s likely they may have gained more weight. Indeed, in studies where subjects have been immediately overfed by approximately 50% of calories, the average (weighted) increase in weight has been 2.8 kg.1 Therefore, our subjects gained 43% less weight than would have been predicted based on scientific research. HOWEVER, it’s important to note, our data is not scientific research and it was in free living subjects. We have simply included the scientific data for speculation and tenuous analysis of what could explain what we have observed. Could what we observed end up not being meaningful? It’s possible, but unlikely in our opinion. Others may disagree and that’s completely fine. We want to emphasize that we do not think reverse dieting is magic, it is merely a tool in the tool box. Whether or not you choose to implement it and how you choose to implement it is up to you. 1. (2017, December 1). The Effects of Overfeeding on Body Composition: The Role of .... Retrieved December 4, 2019, from https://www.ncbi.nlm.nih.gov/pubmed/29399253 CONCLUSION AND CASE STUDIES 146 Individual Case Studies Aria Adamy Aria came to me (Layne) in early 2014 and was a bit of a wreck. She had been improperly coached by a major US competition bikini team and had been very restricted for well over a year (under 1200 kcal/day) but was beginning to binge eat and then over-restrict in response to the binges in order to try to keep her weight down and keep competing. She had originally competed under 105 lbs and was now above 120 lbs and climbing. She wanted to do a conservative reverse which I was skeptical of based on her current situation. We started her at 135 protein, 105 carbohydrate, and 40 fat and 1320 calories. For the first month she struggled with compliance so we kept raising her macros until after a few months she was starting to get consistent with compliance. CONCLUSION AND CASE STUDIES 147 Aria really struggled with the reverse and at first, I was having to talk her off a ledge nearly every week, especially when she started putting on weight. But I assured her that this is what she needed in order to recover, normalize her metabolic rate, and that continuing to restrict was only going to lead to more binges and weight gain. It was a slow grind, but over the course of 10 months we were able to bring Aria’s carbs over 300g and fats over 70g. She gained a little bit less than 10 lbs during that process, but keep in mind that much of that weight gain came early in the process when she was still struggling with binging. Looking back and knowing what I know now, I probably would have been a bit more aggressive with her at the start, but I suppose that’s how even as coaches, we learn and improve. She started her contest prep just under 130 lbs and ended up competing around 107-108 if I recall correctly. It was a relatively easy prep. She never felt like she was killing herself to get in shape and never had to do excessive cardio. After it was over, she never regained a bunch of weight, in fact she never got over 115 lbs, even though we got her macros up to around 135g protein, 250g carbohydrate and 65g fat. The following year we dieted her for another series of shows and it was even easier. In fact, we got to the point where Aria was able to maintain within ~5 lbs of her stage weight year round and still eat over 135g protein, 200g carbs, and 60g of fat per day. Aria went on to win an IFBB Pro Card in bikini and place top 5 at her first pro show. We worked together for several years until late 2017 when Aria decided she wanted a change in direction. In all fairness, I was going through a lot of personal issues and wasn’t able to devote my full attention to coaching at that time. So we parted ways with no hard feelings. Aria worked with a coach who had quite a different approach to post show weight management than I did, and I’m not saying that coach’s method of doing things was wrong, but in my opinion, it wasn’t right for Aria. This coach was much more aggressive with increasing Aria’s calories and she put on much more weight than she liked. When it came time to take it off, she found that she had to be more restrictive and didn’t enjoy the process as much. We began working together again about a year after Aria left. She was at the end of a prep and her macros were very low, her carbs were at 75g and fats were about 30g at a body weight of around 105. We reverse dieted her up to 115 lbs and got her macros to around 260g carbs and 65g fats then brought her back in for the 2019 season. She got back into first callouts and never had to drop her carbs under 100g per day or her fats under 40g per day. CONCLUSION AND CASE STUDIES 148 Aria is the perfect example of how multiple reverses that are done correctly tend to accumulate and results in better and better results each time. I have seen this happen time and time again with clients. If they diet properly, then handle the diet after the diet properly, things end to get better and better. If they diet improperly, then handle the post diet period improperly, things can become worse and worse as this is repeated. Here is what Aria had to say about the process: “I have done multiple reverse diets since 2014, after every competition prep and even during prep between competitions. My most successful reverses have been under the guidance of Dr Layne Norton. I am so excited for this book! Many times the reverse is more difficult than the actual diet itself but it is worth it! Trust me, my 2017-2018 post show was proof! You’ve worked so hard to achieve your fat loss goals, the last thing you want is to regain it all back.

It is a wise investment in your metabolic future.” Shelley Beaty Shelley is a 47 year old mum of 2, who came to me (Holly) in February of 2019, and was eager to begin a diet in the lead up to her and her husband’s 20th wedding anniversary. Shelley has a background in endurance sports events, with a career spanning some 12 years, competing in multiple triathlons and Ironman events, for those of you who don’t know what this involves, an Ironman event includes a 3.8km swim, 180km bike ride and a 42km run. These events require some serious preparation and an absolute commitment to training. CONCLUSION AND CASE STUDIES 150 In the first images you see above, Shelley weighs 138.6 lbs, and she is in a really great place physique wise, and her calorie intake were also in a great place if compare her reported intake to Table 9.1 from chapter 9 regarding normal calorie intake. At the time she contacted me, Shelley was consuming on average 2100 kcals per day and we estimated body fat being ~17%. She had just begun a new resistance training program which included 5 days per week with about 120 mins of LISS cardio. Shelley’s wedding anniversary as 14 weeks away, so we planned to diet her for 12 weeks, allowing for 2 weeks post diet to make a start on a reverse to help get her calories back up for a more enjoyable anniversary with less food restriction, rather than dieting her right into this special occasion and having very little dietary flexibility. CONCLUSION AND CASE STUDIES 151 Shelley hoped to lose approx. 8-10 lbs over the 12 weeks and we also wanted to incorporate diet breaks, (as discussed in the previous chapters, diet breaks are periods of time out of a deficit, where one eats at their maintenance). These were included not only to make the dieting process more enjoyable, but also help minimize lean body mass loss and unnecessary reductions in resting metabolic rate which have been shown in the literature to occur more readily in continuous style of dietary interventions. We targeted a weekly rate of weight loss of around 1.1 lbs per week. That is, 10 lbs of targeted weight loss / 9 weeks of time in a deficit. We added diet breaks at weeks 3, 7 and 10. Based on these time constraints, Shelley would be losing approximately 0.07% body weight per week, which falls within our moderate fat loss definition. More explanation of this can be found in our book ‘Fat Loss Forever’ and ‘The Complete Contest Prep Guide’. CONCLUSION AND CASE STUDIES 152 By the end of the 12 weeks, Shelley achieved her all time best physique and weighed 129.2 lbs. Here is a quick and dirty table detailing her fat loss intervention.

As you can see, Shelley looks absolutely awesome by the end of her diet, and keep in mind she is not a competitor, so I want to emphasise that great things can be achieved by non competitors when you start in a good place and apply optimal dieting strategies. Since this time, Shelley has undertaken a reverse diet, and now at the present time of writing this book (December 2019), has completed some 31 weeks of reverse dieting and will continue to maintain and / or make small calorie increases while exerting her efforts towards growing her glutes for a show in August 2020. Shelley’s weight has indeed increased from a very lean 129.2 lbs up to 135.4 in the present photo shown above. Interestingly, you will note she has not yet returned to her original starting weight, and her calorie intake is now sitting at a very manageable 2438 kcals per day 150g Protein, 270g carbs and 82g Fat. Just to make this clear, she is CONCLUSION AND CASE STUDIES 154 now 3.2 lbs lighter than when she began working with me, and is now consuming 338 kcals more than her previous reported intake every day. Shelley has maintained her resistance training at 5 – 6 sessions per week, and we have been able to reduce her planned LISS to an average of 80 -100 min which is less than when she started. Now Shelley has obviously gained some lean body mass which some might say completely accounts for her increased caloric intake as muscle is more metabolically active tissue. We estimate she gained 3 lbs of lean body mass, now not all of that is muscle but let’s assume it is. Muscle is estimated to only burn an additional 6 kcal/lb per day at rest. So this would equate to an additional 18 calories per day for Shelley. This is not nearly enough to account for her increased caloric intake while maintaining her current weight. Therefore, it’s reasonable to conclude that quite a bit of the increase in her TDEE is via a combination of BMR & NEAT adaptation. CONCLUSION AND CASE STUDIES 155 Jack Dakin Jack is a 29 year old male who came to work with me in October 2018 initially for fat loss, but with the long term goal of improving his physique while doing so on higher calories. His starting body weight was 203 lbs and wished to lose 20 lbs over a 16 week period. His reported maintenance calories at this time were ~2600 kcals per day. During the 16 weeks we included 4 diet breaks, so he spent a total of 12 weeks in a calorie deficit, and therefore his weekly target rate of loss was approximately 1.6 lbs which falls within our modest rate of weight loss 0.08%. Again this was to make the diet process overall more enjoyable, while minimising an excessive amount of lean body mass or significant decreases in his resting metabolic rate. Jack ended his diet 16 weeks later at 182 lbs which was an excellent outcome. See images and a table detailing his fat loss intervention. Note that diet breaks were included at weeks 8, 11 and 14. You may also notice that the calorie increase indicated as diet breaks are not at Jacks calculated maintenance as evidence by his continued weight loss during this time. Insea, these planned breaks were still keeping Jack in a slight deficit as we wanted to accelerate the fat loss, while still being able to provide him with some relief from dieting and calorie restriction.

CONCLUSION AND CASE STUDIES 157 From here, Jack went on to complete a 30 week Reverse diet with the goal of increasing his lean body mass and helping increase his resting metabolic rate. During this time Jack did increase his weight back up to 199 lbs, however he was also able to increase his calories up to very sustainable amount of 3155 per day, 190g protein, 285g carbs, and 95g fat. This is a 555 kcal increase in calories from when he started with me, and to further add to this, he was able to do so while maintaining his total body weight some 4 lbs below his starting weight. Jack has continued to work with me and is currently 10 weeks into his second fat loss program at the time of writing this book. He will be aiming to achieve an even leaner physique with greater amount of lean body mass than his previous fat loss efforts, and ideally achieve a similar, if not slightly higher end of diet calorie intake. Jacks body composition has improved significantly since beginning, Rasmus Hansen Rasmus was a contest prep client of mine who started with me in 2013 and I worked on and off with for many years. He was someone who we were able to get his energy expenditure pretty darn high in the offseason (over 4000 kcal per day) and maintain his weight. Interestingly, he would need constant adjustments during his dieting phase as he would plateau quite often. During his first CONCLUSION AND CASE STUDIES 158 prep with me, by the end of the fat loss phase at his last show he was eating 2295 calories (275/175/55) per day on his low calorie days and around 3000 calories on his 2 weekly high days (250/360/60 if I recall correctly). This was his condition after his final show. Then we began to reverse diet him at what I would consider to be in between a conservative & moderate reverse and crazy stuff started happening. He began dropping more weight and body fat. After 8 weeks he was up to 3365 calories (250/400/85) per day and got LEANER by quite a bit. CONCLUSION AND CASE STUDIES 159 This is where it gets really interesting. Even though Rasmus’ caloric intake was up by quite a bit, he still felt awful. He had low energy, low libido, and felt ‘down’ a lot indicating he was not nearly recovered from the diet. We decided to make more aggressive jumps in calories and after about 12 weeks he had put on some body fat, but was feeling much better and happily traded the increase in body fat for feeling better. This is something important to note especially for competitors. Just because you can get your calories up higher and maintain leanness, doesn’t mean you should. It also doesn’t mean you won’t feel like trash even if your calories get pretty high. This is why we advocate for more aggressive reverse diets in a post show setting at least for the first few weeks. CONCLUSION AND CASE STUDIES 160 Lauren Standbridge Lauren might be my (Layne) most favorite reverse diet case study of all. Lauren is a great example of why not to give up on a reverse just because some weight is gained initially. When Lauren came to me she was maintaining her body weight on just over 1200 calories per day. Now I know what you are thinking “she must be underreporting.” It is possible, but I had her do dietary recalls and food logs with me and whenever she screwed up even a little bit (I’m talking overeating by 10-20g of carbs on one day) she would immediately notify me. I am inclined to believe someone like her who was so forthcoming when she would make mistakes. Lauren was in the difficult position of being on low calories but also having more body fat than she wanted. Lauren did not want to increase her calories, she wanted to lose fat NOW. I was able to convince her that what she was doing wasn’t working and she needed to try another approach and so we began a conservative reverse. So in August of 2017, Lauren began a reverse with me at 1260 calories: 125g protein, 100g carbs, and 40g fat weighing 144 lbs. Over the course of the next 35 weeks, she gained 26 lbs, taking her to 170 lbs and her calories were at 1793 (130/190/57). That is a lot of weight to gain for only having increased her calories by 500. This would lead some people to say she’s a ‘non-responder’ and she should give up on it. I know MANY people that would have. I told Lauren to trust me and if she was gaining that much weight on such low calories, what was dieting going to be like? Lauren was not comfortable with her body fat but I told her to focus on lifting heavy and reminded her that delaying gratification is what makes all the difference in the world. Thankfully, she listened. She peaked at 175 lbs and was eating 2190 calories (130/260/70) at week 54. Then, the unthinkable happened. Lauren started losing weight. From week 54 to week 77 she lost 6 lbs, dropping to 169 lbs, while her calories climbed to 2880 (130/400/85)! Now think about where she was at week 35 (1793 calories) at 170 lbs versus where she went to by week 77 (2880 calories) and lost a pound overall. She added over a THOUSAND calories and didn’t gain weight (overall, it did go up but came back down)! Yes she built significant lean body mass which helped a ton, but we did not increase her training volume enough to account for the difference in the calorie increases vs. weight loss that we observed. Even though CONCLUSION AND CASE STUDIES 161 she was already at a level of calories that would have likely been conducive to weight loss when she hit 2300-2400 calories, I convinced her to keep going. I kept reminding her to keep her eyes on the prize. “Don’t sacrifice what you want most for what you want right now.” She listened and she kept pushing forward. After week 77 came the fun part, we started dieting her. I went with the strategy of having her do 2 aggressive deficit weeks (with 2 higher calorie days each of those weeks slightly below maintenance calories, so a total of only 10 days in an aggressive deficit out of 14), followed by a 1 week diet break at maintenance calories. Her deficit days during the 2 weeks started at 1775 kcal (150/170/55) for 5 days per week, with 2 high days per week at 2370 (135/300/70). This gave her a weekly average calorie intake of 1860 during her deficit weeks. Her diet break weeks were set at 2510 calories (145/325/70). This may have been slightly below her maintenance but I wanted to make sure we stayed in the middle to low end of her maintenance calorie range. She had worked so hard for so long I wanted to make sure she saw some really good initial weight loss to motivate her, and boy did she. She never lost a ton of weight in any one week, but we have been repeating this 2 week diet, 1 week break from week 77 to week 124 (current) and she is down to 148 lbs and looks significantly better than she did at 144 lbs when we started. We have reduced her calories modestly since she has been dieting she has incurred some metabolic adaptation (which is normal). Her calories during her deficit weeks are averaging 1656 and during her diet break weeks she is consuming 2354 calories. She is losing weight on MORE calories now than she was gaining weight on when we started! Think about that for a moment and consider the ramifications. She put in over a YEAR of work reverse dieting to EARN the right to enter a fat loss phase the CORRECT way. She could have continued yo-yo dieting and getting the same results she had been getting. She made the decision and COMMITTED TO THE PROCESS. Now she is reaping the rewards and because she did it the right way, she will get to keep them for the long term. CONCLUSION AND CASE STUDIES 162 CONCLUSION AND CASE STUDIES 163 I’ve been proud of many clients, but I’m not sure I’ve ever had one I’m more proud of than Lauren. I’m convinced 99% of people would have quit within the first 12 weeks. She put in over 2 years of work and now is on her way towards her goal physique and making awesome progress. This is the type of commitment it takes. If you want to believe in unicorns and fairy dust, go try a 4, 8, 12 week challenge off some fitspo on Instagram. Let me know if you keep it off for any reasonable period of time. If you want lasting results, you will have to put in a LOT of work over a LONG period of time! Lauren said about the process: “Reverse dieting was probably one of the hardest but equally rewarding processes I’ve ever undertook. When I contacted Layne I was in a position where due to the post competition diet I was given I had gained over 45lbs in a matter of a couple of months. I was unhappy with my body image and looking for a CONCLUSION AND CASE STUDIES 164 quick fix and I found it hard to adjust to the idea of increasing my calorie intake through the fear of gaining more weight. I also found it hard to accept that I wasn’t in a situation where I could lose the weight I had gained and I would have to remain at this body weight for potentially a long time. However in the end I trusted Layne as my coach and followed the reverse diet plan for a year and a half. By the end of my reverse diet I was able to maintain my bodyweight on near to 3000 calories, I was mentally and physically healthier, more energetic and much stronger. I was in a position where I was then able to diet again in a healthier and sustainable way, and I am now losing weight consuming over 500 calories more than the calorie intake that caused me to gain such a vast amount of weight. Reverse dieting was at first a very difficult and prolonged process but it has definitely been worth being patient and sticking at it. I am so unbelievably thankful for Layne’s help and knowledge on reverse dieting and I am looking forward to another short reverse diet before dieting again to further reduce my body fat.” We hope you’ve enjoyed this book. If you choose to undertake a reverse diet, for many of you it will be more difficult than any fat loss phase you’ve ever done, especially if you have a long history of yo-yo dieting, but the only way to break that cycle is to BREAK THE CYCLE! As the back cover of Fat Loss Forever states: Be tenacious Be persistent Be patient Be consistent Be committed NEVER QUIT Thank you, Layne and Holly
