Thank-you for joining us. Your host will be with you shortly The Body Type Nutrition Academy 2015 The Body type Nutrition Academy 2015 Sugar, Insulin, Energy Expenditure and you. Not a day goes by in the nutritional industry where a finger isn’t pointed or blame laid squarely on a food, food group or behaviour. Learning outcomes » Understand the concept of the calories in vs calories out » » » Model and the basis for the counter arguments as to how this might be oversimplification Appreciate the ways in which athletes manipulate carbohydrate for performance and recovery Understand the arguments for and against high and low carbohydrate diets Appreciate the changes to metabolic rate in relation to dietary choices CICO Calories in – Calories out Thermodynamics The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but cannot be created or destroyed. Metabolic States REE / TDEE and the ‘metabolic fire’ First, some definitions » TDEE – Total daily energy expenditure » Resting energy expenditure People argue for or against fasting, juice diets, high protein diets and in particular ketogenic diets having a “metabolic advantage” are referring to something we discussed last talk. Calorie-for-calorie, can a person in a different metabolic state, have a higher resting energy expenditure. Does a person in ketosis expend more energy than a person not in ketosis? LETS DO SCIENCE! Ketogenic low-carbohydrate diets have no metabolic advantage over non ketogenic low-carbohydrate diets Carol S Johnston, Sherrie L Tjonn, Pamela D Swan, Andrea White, Heather Hutchins, and Barry Sears Thermodynamics Revisited Can we change our energy requirements? Substrate efficiency? RMR? » Energy requirements of the body fall into four components: » Resting energy expenditure (REE) or BMR (e.g., energy required to sustain basic cellular function) » Thermic effect of food (TEF) – the amount of energy required to process and digest food » Activity energy expenditure (AEE) – the amount of energy expended by exercise and non-exercise movement (NEPA and EPOC) » The sum of all of these factors is referred to as Total Daily Energy Expenditure (TDEE) Effects of Dietary Composition on Energy Expenditure During Weight-Loss Maintenance FREE Cara B. Ebbeling, PhD; Janis F. Swain, MS, RD; Henry A. Feldman, PhD; William W. Wong, PhD; David L. Hachey, PhD; Erica Garcia-Lago, BA; David S. Ludwig, MD, PhD Describing weight gain. Calories in calories out is old hat – TDEE > Input is correct. While it is mathematically true that someone who has gained weight has consumed more energy than they have expended, using CICO / Thermodynamics doesn’t help fully explain the situation and is overly simplified and does not take into account many other processes. Application of Studies The Sears study Back to the studies Ketogenic low-carbohydrate diets have no metabolic advantage over nonketogenic low-carbohydrate diets1,2,3 Carol S Johnston, Sherrie L Tjonn, Pamela D Swan, Andrea White, Heather Hutchins, and Barry Sears Are there fat burning Foods? Or are there “enhanced fat burning states” ? Let’s Discuss this…. Low Carb for faster loss? Bottom line: » There is sufficient clinical evidence to suggest that carbohydrate restriction may increase TEE in subjects, though there is great variability across studies » The bigger question is if ketosis does so to a greater extent than would be expected/predicted based on just the further reduction in carbohydrate content. » In other words, is there something “special” about ketosis that increases TEE beyond the dose effect of carbohydrate removal? The Biochemical basis of sports performance – Maughan/Gleeson 2002 The low carb advantage? Why is anecdotal evidence so strong? » » » » » Muscle Glycogen stores and hydration Low intensity activity and failure to know how to train Sedentary population and over-consumption The mentality of simple rules and no-brainer bans Weight loss composition over X weeks for faster initial weight-loss in the uneducated » Tactics employed by diet clubs » Weight gain on high carb diets prior to loss?

The devil is in the dose.
