How Meal Times Affect Weight Loss

Eating Before/After Exercise

Research into eating before and after exercise has shown mixed results, and scientists believe each individual could respond differently to exercise depending on whether they ate before the workout. Currently, the majority of research into eating before a workout suggests this is not necessary for workouts of less than one hour. In fact, multiple studies have shown eating before a workout of sixty minutes or less did not improve exercise performance, and exercising on an empty stomach actually caused participants to use more of their body fat for energy during the workout. However, this did not result in a greater overall body fat loss compared to individuals who ate prior to their workout. For workouts of at least one hour, research shows eating before exercise is beneficial and may improve exercise performance.

While studies on the benefits of eating before a workout show varied results, there is much more consensus on the importance of eating after exercise. Studies indicate eating after a workout is beneficial for exercise recovery. In terms of weight loss, a small study conducted in Belgium indicated individuals who exercised without eating in the morning and then ate a high-fat, high-calorie meal after their workout were able to maintain their weight. This was in contrast to a second group of subjects who ate the exact same meal before their workouts and subsequently gained weight.
