The calculus of calories: mathematical models to quantify obesity and its treatment
Obesity presents a major public health challenge. Many obesity interventions have been proposed to help both individuals and populations, but previous methods for predicting weight loss did not account for dynamic changes in metabolism and body composition as people gain and lose weight.
IRP researchers led by Kevin D. Hall, Ph.D., and Carson C. Chow, Ph.D., created and validated novel mathematical models of human metabolism and body weight dynamics to provide accurate predictions about the development of obesity and its treatment in adults and children.
Award-winning Web and smartphone applications for predicting human weight dynamics based on the new algorithms have been used by more than one million people so far. The models quantify the calorie imbalance underlying the obesity epidemic and predict how interventions will impact body weight in individuals, as well as in entire populations.
