It depends on what kind of exercise it is. It is not suitable for strenuous exercise before and after meals, and there should be a certain interval between exercise and eating.
Due to the movement of muscles during exercise, the whole body blood is redistributed, and a large amount of blood flows to the muscles involved in exercise. The blood vessels of internal organs such as the stomach and intestines are in a state of relative contraction, so the digestive absorption function is also in a state of inhibition, the secretion of gastric juice is reduced, and the digestive ability is weakened. In addition, sympathetic nerve is excited during exercise, and adrenaline secretion is greatly increased, which can also weaken gastrointestinal peristalsis and greatly reduce digestive gland secretion. However, this state cannot be changed immediately after exercise. It takes a certain period of rest to return to normal, and you can't eat immediately after strenuous exercise. If you eat immediately after strenuous exercise, it will affect your digestion and absorption ability. In the long run, it will cause symptoms such as indigestion, loss of appetite and chronic gastritis. Generally speaking, it is more appropriate to rest for half an hour or even longer after exercise.
