Intense Workouts May Curb Hunger


People may actually eat less after exercising than after resting, and a particular type of physical activity—called high-intensity intermittent (HIT) exercise—may suppress hunger best of all. HIT exercise alternates between super-hard work and a recovery period. The study included 17 overweight men who either rested for 30 minutes or spent a half hour performing one of three workouts: moderate-intensity cycling; 60 seconds of high-intensity cycling followed by four minutes of moderate pedaling; or 15-second periods of very high-intensity cycling broken up by a minute of low-intensity exercise. All participants ate a fixed-calorie meal right after their workout or rest period; 70 minutes later, they were offered a second meal. After the very high-intensity workout, men ate 171 and 117 fewer calories than they did after resting or moderate cycling, respectively. The very high-intensity workout had only a 27-calorie edge over the high-intensity one. As a possible explanation, researchers note that HIT exercise decreased levels of the hormone ghrelin, which induces hunger.
