IMC Colloquium Series: "Modeling to Estimate Weight Gain from Energy Imbalances"

Abstract

Several model based approaches have been used to estimate the energy imbalance that accounts for population weight gain in recent decades. These estimates suggest that differences of as little as 50 to 100 calories excess energy intake over expenditure accounts for the rising prevalence of obesity. These estimates have led to the suggestion that small decreases in energy balance should accordingly result in weight loss. We will explore this concept and what population level and individual level models suggest are appropriate strategies to reverse the epidemic of obesity.
