EASY STRENGTH FOR FAT LOSS DAN JOHN The Basic Basics (if you don’t feel like reading all of this) Five days a week, I am recommending this: Get a good night’s sleep. Wake up and drink coffee (or take a caffeine pill…not for me) Keep fasting until you train. Training: 1. Ab Wheel: 1 x 10 2. Vertical Press: 3 x 3 3. Vertical Pull: 3 x 3 or Six singles (adding load or staying the same) 4. Deadlift Variation: 3 x 3 5. KB Swings: Up to 75…push the Heart Rate up. 6. On the last rep, walk out the door and go for about 45 minutes without getting the heart rate over 180 minus your age. (The goal is for onehour workouts…maybe five days a week) Veggies and Proteins at meals; Drink Water all day as appropriate Two “Gut Biome Breaks:” Fermented foot (I like sauerkraut) and a piece of fruit (I like apples, my daughter can’t eat them, so choose wisely). Just before a meal is fine, I like to do it between my two daily meals. On the other two days, do some additional Original Strength work and go for a stroll, but keep doing everything else. The devil is in the details. Here we go: I’ve been getting a lot of emails and podcast questions about using the Easy Strength model for fat loss. I am happy to report that people ask about fat loss now and stopped using “weight loss.” If I cut your leg off, you lose weight. It’s not the same as fat loss. Listen, it’s going to be some effort to lose body fat. I think gaining Lean Body Mass is the most difficult thing to do…followed closely by losing body fat. Yes, that’s what people want. It is far better to NOT gain the fat than to try to lose it. Not long ago, Pat Flynn and I had a fun conversation about a question Covert Baily was once asked: “What would you do if you ‘woke up fat?’” I promised Pat that I would write a Pirate Map for this and…here you go: If I woke up fat Pirate Map…for Pat Flynn’s Chronicles of Strength Basically, we would have to look at three interlocking keys: • • • Belly Biome Appropriate Training Sleep but also general recovery and joint mobility We all know that I am going to say: “Eat protein, eat veggies, drink water” and “More protein, more veggies, more fish oil.” And, that is true. But there is more: a lot of new research is telling us that the gut biome is probably an issue for depression, some nervous disorders and, hopefully, the obesity epidemic. As important as I think that nutrition is the key to fat loss (“fat loss happens in the kitchen”) perhaps the overuse of antibiotics, plastics in the food, odd chemicals in fast food and the aggressive behaviors food producers use to entice us to eat more beige food makes simply saying “eat less” counterproductive. We must also learn to train on the edges of the Power Laws for fast loss. Intense short sessions followed by long walks “seems” to get the body in a state ready for fat burning. Finally, many people sleep poorly and never really recover. As we sit too much in chairs, we cement our bodies in ways that make it difficult to move AND difficult to get comfortable to sleep at night. So…my answer to “What I would do if I woke up fat!” Here is my Pirate Map. 1. Before bed, make coffee and set the timer to wake me up to the smell of coffee. Take medications or supplements…if needed. Have one serving of Orange Flavored Sugar Free Metamucil (it is doing wonders for my blood profiles). Make the bedroom as dark and as quiet as possible. 2. Wake up and drink coffee (answer calls, emails, forums and write as needed) for a few hours. Sure, drink some water too. FAST while you work. Three Days a week 3a. Hopefully, after about 15 hours of fasting, do some kind of short (4-15 minute workout) that has some level of full body movements and some intensity. I use barbell complexes; Pat has plenty of KB complexes. A four-minute Tabata Front Squat could be done every so often. Get the HR up, “get sweaty” and get done. Immediately, WALK for as long as you can. This is when you burn fat. I find about two miles with my ankle weights and hand weights to be just about perfect. You can also use cardio machines, but do NOT push the Heart Rate! 3b. During the other days of the week, do a fasted mobility “work out.” I use Tim Anderson’s Original Strength. Enjoy it. Breath and just let it flow. 4. Eat 2-3 meals a day loaded with veggies…and whatever else. One thing: BEFORE each meal, eat a few forkfuls of sauerkraut…or other fermented food. Not much is needed. 5. 1-2 times a day, eat a single piece of fruit (I choose apples) and perhaps some veggies, sauerkraut, and, if necessary, some fish. (I will often have a can of sardines if I somehow get “famished!”) 6. Take some time daily to meditate, read and self-reflect (writing in a journal can be gold). I also use the apps, One Moment Meditation, and Brain.FM to guide me here. And, that’s it. I honestly think there is magic in fasting, Metamucil, sauerkraut, the apples and the intense workout followed by the walk. The OS work and “time to myself” not only deal with stressors but set you up for a better night’s sleep. Every so often, I might increase my fast by doing the Fast Mimicking Diet or perhaps simply fasting from dinner to dinner. That’s a “might.” Would I would NOT do is…more. Let the body rebuild its biome, let the fat burning process happen appropriately and take care of sleep and stress. Don’t add MORE stress! That’s what I would do. (End program for Pat) That’s not bad. More clarity would be nice. These are the complexes I used for this in barbell work: Complex A Row Clean Front squat Military press Back squat Good mornings Complex C (It’s called “C,” from the work I have done in the past. This program doesn’t have all the others…including “B.”) Hang snatch Overhead squat Back squat Good mornings Row Deadlift Barking Knees Complex Snatch Grip RDL Snatch Grip High Pull Hang Power Snatch Good Morning Rows (A fuller examination of complexes is at the bottom.) But here is the problem: I love complexes. After about three weeks of doing them daily, I HATE complexes. It got me thinking a bit. Thinking. That’s a good thing. Could it be possible to make the lifting even easier than complexes? Getting strong easier? Hmmm. Like Easy Strength? I started wondering about something Rusty Moore talks about a lot. His ideal muscle building workout for fat loss is, basically, Easy Strength. He feels that the ES style of training leads to a kind of muscle tone that looks good with lower body fat numbers. He takes the concepts of Easy Strength and applies them to “looking good!” By using the concept of “irradiation,” loosely based on Sir Charles Scott Sherrington’s Laws, the idea is simply that one can add more load to the bar and stimulate more muscle fibers by consciously willing the rest of the body to kick in and help out. Moore summed the basics brilliantly with his post on One Arm Presses: Mastering the One Arm Press Requires Mastering Irradiation https://visualimpactfitness.com/the-one-arm-military-press/ The second workout I did with one arm military presses, I was struggling a bit to get 60 pounds moving. Then I decided to use irradiation in my favor. I first make a fist with the arm I wasn’t using, let that tension increase across my body and when it hit the side I was lifting with I tightened my grip on the dumbbell and easily lifted it overhead. Now I simultaneously do this while also tightening my abs. I haven’t tried flexing the legs yet, but I am guessing that will help me reach the next level. This is where I am heading now. End quote. Moore developed this into a brilliant program called Visual Impact Frequency Training. He offers an amazing program here: http://dj84123.visimpact.hop.clickbank.net/?id=frequency (I am on an affiliate link here, but I bought it for myself. I am NOT recommending it for the income I will get on the affiliate; it’s a great program. It goes in a different direction than ES, but it might be worth your time.) Yes, Easy Strength builds strength. But many people noticed that after a few workouts they felt better and “looked” better. Robb Wolf has a wonderful phrase, hormonal cascade, to explain that magic that happens when you train appropriately and good things happen to your body. I think a program that stresses strength will also encourage your body to turn around. “How” does it work? Well, I am working on this. At the end of this whole discussion, you will find information concerning studies about combining Resistance Training (RT) with other work. It’s science! I like Rusty Moore’s idea that when you lift, do intense work, you free up fatty acids and the walk after the lifting deals with the free fatty acids. He sums it as: Intense exercise releases free fatty acids, strategic cardio burns free fatty acids. That might be worth memorizing. Coffee frees up the fatty acids too. It seems like every day someone is discovering a new benefit for this delightful beverage. Coffee makes fasting easier (maybe it’s as simple as freeing up the free fatty acids), gives us a bit of a push when we train and helps many have the urge to eliminate the bowels. Win. Win. Win. Someone asked me once how fasting helps with fat loss. My answer was brilliant: you don’t eat calories if you are not eating. How did I not get the Nobel Prize? So…fasting, coffee, and the intense work all work together to get the free fatty acids up and at ‘em then the walking burns ‘em off. It seems like stealing in the fat loss game. Let’s review the basic idea: Five days a week, I am recommending this: Get a good night’s sleep. Wake up and drink coffee (or take a caffeine pill…not for me) Keep fasting until you train. Training: 1. Ab Wheel: 1 x 10 2. Vertical Press: 3 x 3 3. Vertical Pull: 3 x 3 or Six singles (adding load or staying the same) 4. Deadlift Variation: 3 x 3 5. KB Swings: Up to 75…push the Heart Rate up. 6. On the last rep, walk out the door and go for about 45 minutes without getting the heart rate over 180 minus your age. (The goal is for onehour workouts…maybe five days a week) Veggies and Proteins at meals; Drink Water all day as appropriate Two “Gut Biome Breaks:” Fermented foot (I like sauerkraut) and a piece of fruit (I like apples, my daughter can’t eat them, so choose wisely). Just before a meal is fine, I like to do it between my two daily meals. On the other two days, do some additional Original Strength work and go for a stroll, but keep doing everything else. Vertical presses can be anything you like overhead. I have lots of bells and bars, so I have more options. If you only have one kettlebell you might want to have a mix of moves. Easy days: Standing single presses. Hard days: Bottoms up presses Medium days: Half kneeling presses. Remember the rules for ES: NEVER miss!!!! Never come close to missing. Get the reps in. Vertical pulls can be any member of the pull up/chin up family. Some may utilize suspension trainers or others, machines. I still think that six single pull ups done as explosively as possible is a tremendous strength movement. If you can’t get vertical pulls, do something that makes sense to you. On the deadlift variation, whatever works for you. The person with the single KB might just have to do some one-legged variations…or whatever. It’s impossible to come up with all seven billion variations of this training program. For most people, the swings are going to be ugly. I suggest you try my Bulgarian Goat Bag Swings and save yourself the issues caused by poor swings. With BGBS, keep the reps around 50. If you just do Hip Thrusts, think three sets of 25 but be sure to get up and down off the ground each time. The ab wheel, in this program, is the warmup. In my new book, Attempts: Essays in Health, Fitness, Longevity and Easy Strength, I go into more detail but I can finally feel comfortable telling people that one does not have to change weights or exercises to get some of the odd benefits of the ES training approach. It works. I just don’t know the why or how. So, when I just had my 28-kilo bell, I could have done: 1 x 10 Ab wheel 3 x 3 Presses Six single pull ups. 3 x 3 Single Leg DLs R/L 5 x 15 Swings and OUT THE DOOR for my walk. (Someone asked if you do one exercise THEN move on or if you do circuits. Both, I guess, would be fine, but I do one exercise and then move on to the next. YMMV) It’s not bad at all. Pretty good really. I am NOT recommending the following. Years ago, my doctor, who is also a former student of mine, put me on drug called Metformin (Glucophage). Since picking up a liver parasite in the Middle East, I have struggled with my fasting glucose numbers. He told me that this very inexpensive drug (at most, five cents a day) would “empty my liver.” Later, I read that some research is leaning into the idea that this drug helps with longevity. All I know is that I used to live around 110-120 on my annual blood test (fasting glucose number) and now I am 81. Does that mean my liver wakes up “empty?” Dunno…I’m already out of my element here…way out of my depth. But here is the idea: if you are facing diabetes (or “pre-diabetes” as I was told I have), this cheap pill might set off a nice chain of events with ES program for fat loss. Obviously, see a doctor. I am not giving medical advice just being candid about my experiences. Resources for this article Rebuild Yourself with Complexes by Dan John If I ever recommended a workout that cut fat and built muscle at the same time, I'm not sure I'd believe myself. After all the late night television hucksters, I'm not sure what to believe anymore. But then, last week, a student came up to me during the transition of our workout and asked, "Coach, can I get a copy of all the complexes for my dad? The rest of the guys in the fire department want to do them, too." "Well, sure," I said. "Why?" "Coach, everybody's getting huge." So, without buying a plastic gizmo or a DVD of me in a tank top sweating to bad music, let's discuss complexes. It All Started When... After eight years in a Catholic elementary school, I moved on to a public junior high school and discovered how sheltered my life had been. Southwood Junior High in South San Francisco was a far cry from the quiet confines of my parish school with the good Irish nuns. One thing we did have at Southwood was a fabulously simple weight training program. Our Southwood workout, as I discussed in detail in a previous article, was very straightforward: Power clean x 8-6-4 Military press x 8-6-4 Front squat x 8-6-4 Bench press x 8-6-4 On one particular day, our instructor, Mr. Freeman, due to a short class period for an assembly, simplified things even more. We just had to do power cleans, military presses, and front squats for eight reps followed by a short rest as one's partner did the three exercises. Then we'd do them for six reps before finishing with four. Without the bench press, this workout sounded easy. He added one little thing, though: You couldn't put the bar down once you started the three lifts. It's that back-to-back brutality that adds up, my friends. I choked on those last reps of the front squat trying to figure out where I left my lungs. That was my first complex. Going Back in Time The roots of complexes are fairly deep. It reflects the peripheral heart action (PHA) workouts pioneered in the 1960s by Mr. America, Bob Gajda, who also assisted the legendary Sergio Olivia. You can find more about it in John McCallum's Keys to Progress. Here's an example of one sequence from a PHA workout: Front squat x 12 Cuddle sit-ups x 25 Curls x 10 Seated twists x 25 Wrestler's bridge x 10 Then you rest and repeat the sequence four total times. You'd then do up to three or four other sequences during this workout. It had advantages, as it seemed to burn a lot of fat and covered every body part imaginable. There's an obvious problem with PHA. You have to have a lot of equipment, and it's nice to be able to move from dumbbell to barbell to chin-up bar without having to wait or find the stuff you just left there a minute ago. Those of us who have trained in college gyms or public establishments know that equipment will literally walk away to another corner as you move from exercise to exercise. For many of us who trained in the 1970s, the Universal Gym was the answer to this problem. I had football workouts that were simply this: Bench press Lat pull-down Leg press Hyperextension Leg extension/leg curl Neck harness Wrist roller Shoulder press Incline sit-up After thirty seconds at each station, the coach would blow the whistle. We'd move over and continue training. This workout could accommodate a lot of athletes and, for what is was, this was a good workout. The Nautilus machine workouts were also believed to improve cardiovascular condition by moving quickly from station to station. It also allowed the gym owners to shuttle clients out of the gym quickly, too. Once again, if you have to find out anything and everything under the sun about weightlifting, pop open your copy of John Jesse's Wrestling Physical Conditioning Encyclopedia. In its pages, you'll find every variation, trick, and special equipment ever conceived for strength training. The chapters on circuit training and endurance cover many of the basic principles of complexes. Complexes, the Javorek Way In the past few years, Istvan "Steve" Javorek's work with complexes has been stolen and repackaged many times. I have to make a short nod to something he notes on his website: "From what I've heard, from the far end of Siberia to Iceland to California, thousands of coaches are performing with their athletes Javorek's complex exercises, but some of them give credit to themselves. I really worked hard on developing these exercises and I like to share with everyone my 'little secrets,' just give credit to the 'creator.' "My original goal with the complex exercises was to find an efficient and aggressive method of performance enhancement that saves time and makes the program more enjoyable. If you choose to use these (in some form) with your athletes, be honest and call your new complex exercises 'Variation to Javorek's Complex Exercises.'" Javorek's complexes are brilliant and have all the keys to success for someone contemplating them. Javorek's Barbell Complex #1 Barbell upright row x 6 Barbell high pull snatch x 6 Barbell behind the head squat and push press x 6 Barbell behind the head good morning x 6 Barbell bent-over row x 6 More Complexes, More Pain Another master of the complex is Alywn Cosgrove. After the Velocity Diet, I began doing Alwyn's Afterburn II program and soon discovered that simply doing complexes on their own was one of the biggest oversights in my training career. I suggest you check your ego at the door before you begin Afterburn II. Alwyn's insights include one variation for the busy person that I'll address in a moment. My definition of a complex is simple. A complex is a series of lifts back to back where you finish the reps of one lift before moving on to the next lift. The barbell only leaves your hand or touches the floor after all of the lifts are completed. Although you can do them with dumbbells or kettlebells, I argue that we only use barbells. Certainly, there's great value in the other tools, but for getting athletes bigger, I like to use the heavier bar. The key to organizing a complex is to make sure that the bar passes over your head in some kind of logical manner. In other words, if you do rows first, followed by back squats, how did the bar get there? I try to have the bar pass backwards over the head after a few lifts, but only pass forward again one time. So, when you try these (it's probably best to use a broomstick first), note that it'll save you some effort if you think about the exercise transitions before you get too heavy. For example, if you have a military press before a back squat, on the last military press rep, lower the weight to the back. Take a minute to think them through before going for a max on these complexes. Your rest periods should be longer than what you originally think. Like most of my workouts, these appear easy on paper. The most difficult thing to consider is the rep range. For a fat burning hit and a massive conditioning bang, try doing sets of eight. Complex A for Eights Row x 8 Clean x 8 Front squat x 8 Military press x 8 Back squat x 8 Good mornings x 8 Gently place the bar on the ground and rest! I like sets of three for adding mass to my young athletes. The more time under the bar, the more the body adapts by getting bigger. Moreover, it seems to also be most helpful on the playing field. When you watch a sophomore boy handle Complex A with 155 for three complexes of three reps each, you have to realize that this is a very strong human being, even if he's just 15. You can play with any rep variations you like, but I've found that eights and threes are the best. If you do five sets of eight, you probably won't be doing much more in this workout. Three sets of three make an excellent pre-lift warm-up or, with heavier weights, can be used as a strength and mass building workout. The sets seem to be almost geometric in the impact on the body. Err on the side of caution for the first few workouts before attempting more than three sets of complexes. Alywn Cosgrove adds another variation that I use for strength building. Basically, you drop a rep each set and add weight. Now, be careful here, as the weights go up quickly. Let's look at Complex C with this variation: Complex C Hang snatch Overhead squat Back squat Good mornings Row Deadlift Set 1: 8 reps with the bar, 45 pounds Set 2: 7 reps with 65 pounds Set 3: 6 reps with 85 pounds Set 4: 5 reps with 105 pounds Set 5: 4 reps with 125 pounds Set 6: 3 reps with 145 pounds Set 7: 2 reps with 165 pounds Set 8: 1 rep with 185 pounds Now, there's an assumption here that you can snatch 185, then complete the workout. Again, on paper, this looks easy. One other thing I like to do is to print out each complex in size 68 Arial font so that I can see the whole series on the ground in front of me. Place the sheet about three feet in front of the barbell and simply keep your mind on the exercise at hand. Use the sheet to remind you to move to the next exercise. With my large groups, I have the sheets all in plastic protectors, and we save them for weeks at a time. The Select Six Now it's time I offer you my six favorite complexes. Note that each has six lifts and many of the exercises will be fairly familiar to all of you. If you don't know how to do a lift, don't do it. Complex A Row Clean Front squat Military press Back squat Good mornings Complex B Deadlift Clean-grip high pull Clean-grip snatch Back squat Good mornings Row Complex C Hang snatch Overhead squat Back squat Good mornings Row Deadlift Complex D Upright row Clean-grip snatch Back squat Behind the neck press Good mornings Row Complex E Power clean Military press Back squat Good mornings Behind the neck press Front squat Complex F Overhead squat Back squat Good morning Front squat Rows Deadlift Complexes Keep it Simple I find that swimming through these three times a week eliminates boredom. If you only do them twice a week and play with the three reps schemes (eights, threes, and 8-7-6-5-4-3-2-1), you have 18 workout ideas that'll last nine weeks. When I sell this on late night TV, I'll be the guy with the ponytail and spandex. The Basics of Gut Biome: The Future…a Personalized Approach https://individualizedmedicineblog.mayoclinic.org/2019/02/08/personalized-diets-foodsshaped-to-your-lifestyle-genetics-and-gut/ With this knowledge, Dr. Iyer took a personalized approach to modifying his diet. “I don’t have to give up all carbohydrates. Instead, I’ve cut down on just the carbohydrates that cause my blood sugar to rise, like rice and wheat grains. I am eating more proteins such as eggs and cottage cheese that keep my blood sugar steady. And I’m staying away from sugary breakfast cereals and yogurts. I’ve lost a little bit of weight and I feel more energetic,” he says. End quote. Probably the Single BEST Discussion of this Gut Biome Idea https://getpocket.com/explore/item/how-the-western-diet-has-derailed-our-evolution This first selection, frankly, amazed me as I read it. Indeed, when Sonnenburg fed mice plenty of fiber, microbes that specialized in breaking it down bloomed, and the ecosystem became more diverse overall. When he fed mice a fiberpoor, sugary, Western-like diet, diversity plummeted. (Fiber-starved mice were also meaner and more difficult to handle.) But the losses weren’t permanent. Even after weeks on this junk food-like diet, an animal’s microbial diversity would mostly recover if it began consuming fiber again. This was good news for Americans—our microbial communities might re-diversify if we just ate more whole grains and veggies. But it didn’t support the Sonnenburgs’ suspicion that the Western diet had triggered microbial extinctions. Yet then they saw what happened when pregnant mice went on the no-fiber diet: temporary depletions became permanent losses. When we pass through the birth canal, we are slathered in our mother’s microbes, a kind of starter culture for our own community. In this case, though, pups born to mice on Americantype diets—no fiber, lots of sugar—failed to acquire the full endowment of their mothers’ microbes. Entire groups of bacteria were lost during transmission. When Sonnenburg put these second-generation mice on a fiber-rich diet, their microbes failed to recover. The mice couldn’t regrow what they’d never inherited. And when these second-generation animals went on a fiberless diet in turn, their offspring inherited even fewer microbes. The microbial die-outs compounded across generations. End quote. The following really got me thinking about how much more complex things are in life. Let’s continue to read: The problem with the fiber hypothesis, however, has always been twofold. People who eat plenty of fiber seem to have a lower risk of many diseases, including heart disease and diabetes. But when scientists have fed fiber to volunteers, they haven’t historically observed much benefit. And this underscores the real mystery: By what mechanism does fiber improve health? Soluble fiber is an umbrella term for complex plant sugars—including some polysaccharides, oligosaccharides, and fructans. The molecules consist of simple sugars linked together in long, hard-to-dismantle chains. If you dump a load of fiber—or microbiota-accessible carbohydrates—onto a colonic community of microbes, those that specialize in fermenting it will bloom. And they’ll start churning out short-chain fatty acids, including butyrate, whose smell you might recognize from aged cheese, and acetate, which gives vinegar its sharpness. These acids, Sonnenburg thinks, are one of the long-sought mechanisms by which fiber prevents disease. Rodent studies suggest that as they diffuse into circulation, they stimulate the anti-inflammatory arm of the immune system—cells that help you not attack tree pollen and other harmless proteins—preventing allergies and other inflammatory diseases. The calming effect reaches as far as the bone marrow and lungs, where, as a recent Nature Medicine study showed, the acids reduced animals’ vulnerability to asthma. As Justin Sonnenburg put it, “We have this unsupervised drug factory in our gut.” The question facing microbiologists today is how to properly tend to that factory. End quote. Finally, a bit of an answer for you to use right away: Years ago, impelled in part by their oldest daughter’s constipation problems, the Sonnenburg family revamped its diet. They threw out all processed food-stuffs, and began eating plenty of veggies and whole grains. They bought a dog. Justin Sonnenburg began hand-milling his own wheat berries for bread. He took up gardening. And when he compared his archived microbes from years ago with recent ones, he discovered that his microbial diversity had increased by half. “That’s a huge difference,” he told me, “as big as the difference between Americans and Amerindians.” End quote. Some Information on Free Fatty Acids http://www.faqs.org/sports-science/Fo-Ha/Free-Fatty-Acids-in-the-Blood.html The free fatty acids released from adipose tissue can be utilized anywhere there is an energy need within the body. The process of releasing these compounds begins with a signal from the pancreas, the organ responsible for the monitoring of glucose concentrations in the blood. When a low glucose level is detected, the glucagon hormone is released to stimulate glucose release from the stores of glycogen in the liver. If the blood level of glucose is too high, the body releases the hormone insulin. In this circumstance, fatty acid production will be stimulated through the further trigger of the chemical lipase in the adipose tissue. The ultimate destination of the released fatty acids is the mitochondria of the subject cells that require energy. The mitochondria is the powerhouse of every cell. There is a well-known correlation between the consumption of caffeine and the metabolizing of free fatty acids. Caffeine promotes the process of lipolysis, the breakdown of the triglycerides stored in the adipose cells. There is also a scientifically established linkage between the increased presence of fatty acids in the bloodstream and the onset of diabetes, the disease whereby the body produces insufficient amounts of insulin to properly regulate the level of blood sugars (glucose). While fat, in the form of fatty acids, is a very desirable energy source, it is dependent on the presence of oxygen to be useful. In circumstances where energy is required by the body more quickly than oxygen can be delivered to the required location, the body will switch to its less energy efficient anaerobic system. When the body is using one of its anaerobic energy systems, it cannot burn fat, but it will simply generate less energy and will sustain a greater glucose depletion. End Quote Metformin https://www.webmd.com/diabetes/metformin-cause-weight-loss Scientists have also been trying to understand how metformin leads to weight loss. Because it alters gut bacteria, digestive issues are common side effects. So one early theory was that stomach pain caused people to lose their appetite and eat less, or that they lost water weight from diarrhea. But most of these side effects go away in a few weeks. People who lost weight on metformin continued to lose pounds after that time. A more likely explanation is that metformin’s changes in the gut tamp down appetite. It may raise the body’s levels of the hormone leptin, which makes you feel full. Since your appetite isn’t working overtime, you eat less. The weight you lose on the drug comes mostly from fat stores, not the mix of fat and lean muscle that happens with dieting. People on metformin also saw lower waist measurements and waist-to-hip ratios, two ways to measure body fat. Is Metformin an Effective Weight Loss Pill? No. Exercise, Coffee and “Lipids” https://www.sciencedirect.com/science/article/pii/S1728869X1200010X “Results Peak values for performance and ventilatory parameters for exercise trials under placebo and caffeine conditions are shown in Table 1.
