Keynote: “Calories In vs. Calories Out” - an out-dated model for weight loss. It’s Quality over Quantity that matters.
“The definition of insanity is doing the same thing over and over again and expecting different results” - Albert Einstein.
Each year millions of “dieters” around the globe embark on strict calorie-controlled, low-fat diets yet the research is abundantly clear that low-fat calorie-restricted diets are ineffective at achieving long-term weight loss.
Human biology evolved over millions of years to ensure that, when faced with calorie restriction, metabolic adaptations follow that increase hunger, decrease energy expenditure and facilitate fat storage. Results may be realised in the short-term but it is these ancient survival mechanisms that ultimately work against long-term weight loss in today’s climate of unlimited food availability. And whilst quantitative approaches to “dieting” may produce annuity streams for weight-loss companies, they can impair individual metabolisms due to the alterations in body composition that come from “yo-yo” dieting; e.g. reduced muscle mass and the resultant lowered basal metabolic rates and increased adiposity.
This session will examine how food is information which, good or bad, affects our hormones, our metabolisms and the expression of our genes. We will make the case for “quality over quantity” and show that by changing the macronutrient composition of the diet towards higher fat (and lower carbohydrates), reductions in glycemic load initiate fat oxidation, causing adipocytes to release energy reserves that are otherwise trapped, increasing available calories into the blood stream resulting in hormonal changes that reduce appetite and increase basal metabolic rate. We will show that the type of calories going in can affect the amount of calories going out and that perhaps a qualitative approach is needed to tackle the obesity epidemic.
