Exercise Reduces Hunger Pangs
Exercise blunts the effect of food on the mind, according to a study of women who were shown images of food after exercising for 45 minutes or staying still. Both normal-weight and obese women had less interest in food (as measured by brain scans) after exercising than on days when they didn't exercise. Food journals revealed that the women consumed the same amount regardless of exercise. But the women didn't eat more food to compensate for extra activity and continued to get more physical activity throughout the day after morning workouts.
