At night, the metabolism of human digestive system is the slowest, so it is not recommended to eat after exercise or before normal sleep. After you are healthy, you will feel hungry. If you eat it, on the one hand, it will increase calories, which is equal to white exercise. On the other hand, you can't digest the food in your stomach because you eat too late, which will affect your digestive system.
If you are hungry after fitness, you can drink some water or nutrient solution to compensate for energy. Eating is not recommended.
