Estimating the changes in energy flux that characterize the rise in obesity prevalence

This relation suggests that substantial increases in TEI have driven the increases in body weight over the past 3 decades and the obesity epidemic will not be reversed without large reductions in energy intake, increases in physical activity, or both.

Abstract

This relation suggests that substantial increases in TEI have driven the increases in body weight over the past 3 decades. Adults have a higher proportional weight gain than children for the same proportional increase in energy intake, mostly because of a higher fat content of the weight being gained. The obesity epidemic will not be reversed without large reductions in energy intake, increases in physical activity, or both.
