Abstract

PURPOSE: This study aimed to examine the effect of exercise training over 10 months at two levels of energy expenditure on energy and macronutrient intake in a sample of previously sedentary, overweight/obese young adults. METHODS: We conducted a 10-month trial in 141 young adults who were randomized to either supervised exercise 5 d·wk(-1) at 400 and 600 kcal per session or nonexercise control. Participants were instructed to maintain their usual ad libitum diet. Energy/macronutrient intake was assessed at baseline and 3.5, 7, and 10 months over 7-d periods of ad libitum eating in a university cafeteria using digital photography. Foods consumed outside the cafeteria were assessed using multiple-pass recalls. RESULTS: There were no significant between-group differences in absolute energy intake at baseline or at any other time point in the total sample or in men. In women, absolute energy intake was significantly greater in the 600-kcal-per-session group versus controls at bot
