Should you exercise before or after meals?

Nowadays, many people suffer from obesity due to carelessness in their diet, so losing weight has become a slogan that many people often shout. However, some people lack willpower and end up getting fatter and fatter. Therefore, many people resort to exercise to lose weight, but many people don’t know much about exercise. Is it better to do weight loss exercises before or after meals?

It is not advisable to engage in strenuous exercise before or after meals. There should be a certain interval between exercise and meals.

During exercise, the activity of muscles redistributes blood throughout the body, and a large amount of blood flows to the muscles involved in the activity. The blood vessels of internal organs, such as the stomach and intestines, are in a state of relative contraction. Therefore, the digestion and absorption functions are also inhibited, the secretion of gastric juice decreases, and the digestive ability weakens. In addition, the sympathetic nerves are excited during exercise and the secretion of adrenaline is greatly increased, which can also weaken the peristalsis of the gastrointestinal tract and greatly reduce the secretion of the digestive glands. However, this state cannot be changed immediately after exercise. It takes a certain amount of rest to return to normal, so you cannot eat immediately after intense exercise. If you eat immediately after intense exercise, it will affect your digestion and absorption ability. If this continues for a long time, 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 before eating after exercise.

Similarly, you should not engage in strenuous exercise immediately after a meal. If you engage in strenuous exercise immediately after a meal, the blood that is currently involved in gastrointestinal digestion will be redistributed and flow to organs such as muscles, which will also affect gastrointestinal digestion and absorption.

Participating in strenuous exercise immediately after a meal may also cause abdominal pain and discomfort due to gastrointestinal vibration and the involvement of the mesentery, which is not good for the body and exercise. Therefore, you should wait at least one and a half hours after a meal before exercising.

In addition, the best time to exercise for weight loss is best arranged in the following three time periods.

1. Don’t forget summer

Summer is the golden season for weight loss exercises. Due to weather reasons, even a little exercise can produce considerable consumption, which is exactly what is necessary for losing weight.

(2) The morning is the most important part of the day

The calories needed for morning exercise are also provided by the oxidation of stored fat in the body. Obese people are overweight and have too much fat accumulated in their bodies. Therefore, weight loss exercises must seize the "golden time" in the morning.

(III) Before and after meals are good opportunities (not strenuous exercise)

1. Exercising 30 to 45 minutes before meals can help you lose weight. The reason is: decreased appetite and reduced food intake. During physical exercise, the motor center of the cerebral cortex and the sympathetic nerves are in a highly excited state, while the food center is relatively inhibited and the secretion of the digestive glands is inhibited.

2. Doing physical exercise 30 to 45 minutes after a meal can also have a significant effect on weight loss. Exercising 30-45 minutes after a meal can help you lose weight because your digestive and absorption functions are weakened. Exercising after a meal causes sympathetic nerve excitement and massive secretion of adrenaline. Due to the need for muscles to work, the central nervous system redistributes blood with slow action to relieve emergency situations. The arterioles in the muscles dilate and the capillaries open in large numbers, increasing the blood flow to the motor organs. On the contrary, the blood flow to the digestive organs such as the gastrointestinal tract decreases.

After reading the detailed introduction given by the editor above, I believe you have a certain understanding of sports! Generally speaking, it is best to exercise before or after meals according to your needs, but it should be noted that it is best not to exercise vigorously right after a meal. If you exercise vigorously right after a meal, it will cause indigestion and may even cause stomach diseases.
