People who gain muscle are suitable for eating after fitness. Fitness generally has two purposes, muscle gain and weight loss. For people who gain muscle, the general advice is to eat after fitness, which will consume a lot of calories. Eating after exercise can supplement nutrition and greatly improve the fitness effect. However, don't exercise on an empty stomach. It is best to eat some foods that are easy to digest and absorb, such as bananas and yogurt, to avoid hypoglycemia due to insufficient energy and unable to complete exercise.
People who lose weight are suitable for eating before fitness. The purpose of fitness is to lose weight. It is recommended to eat 2 hours before fitness. By this time, the food has probably been digested. When exercising, it can not only consume the calories consumed before, but also prevent more food calories from accumulating in the body to form fat. Moreover, if people who lose weight go to fitness without eating, it will easily lead to excessive energy consumption and overeating after fitness, which is not good for weight loss.
Why shouldn't you exercise immediately after eating? At this time, the digestive organs need sufficient blood supply to digest food. If you go to exercise immediately, most of your blood will be supplied to the exercising muscle organs, while the blood in the digestive organs will be reduced, which will lead to weakened gastrointestinal peristalsis, affect digestion and even cause gastrointestinal diseases.
Therefore, people who want to eat before fitness should eat 1-2 hours in advance.
