Traditionally, it is believed that "walking after meals helps digestion". Walking after meals can certainly promote gastrointestinal peristalsis and digestion, but it is not appropriate to do a lot of exercise after meals. Modern sports medicine experts have found that it is most appropriate to arrange exercise time before meals.

Doctors have confirmed through tests that exercise before meals can improve the metabolic rate in the body. After the exercise stops, the metabolic rate is still at a high level and will continue to consume calories in the body. In addition, exercise before meals can also reduce the storage of glycogen, so that the ingested food can be converted into sugar and consumed by the body, and it is not easy to be converted into fat and stored in the body.

Eat at regular intervals after exercise. Because in the process of exercise, a large amount of blood flows to the muscles involved in exercise, the blood vessels of organs such as stomach and intestine are in a state of relative contraction, and the digestive absorption function is also in a state of inhibition, which weakens the digestive ability. 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.
