Abstract
This project assessed the effects of a preexercise glycemic load (GL) on postexercise hunger and energy intake in healthy active women (n = 12) using a randomized crossover design of 2 trial days each separated by 1 week. Thirty minutes after eating either a low- or high-GL breakfast, participants completed moderate aerobic exercise for 30 minutes. Hunger was recorded on a visual analog scale (10 cm long) and dietary intake was recorded for 2 consecutive days. Breakfast GL affected the 2-hour postexercise hunger rating (High-GL = 7.2 vs Low-GL = 4.67, P < .01) and energy intake during the first postexercise eating episode (High-GL = 703 vs Low-GL = 439 kcal, P = .001). A Low-GL preexercise meal appears to affect subsequent hunger and energy intake.
