1. Loss of appetite for one or two hours after exercise: After high-intensity strenuous exercise, hunger will really decrease in a short time, and generally you will eat less 10%. The personal feeling of some friends is that they have no appetite at all for an hour or two after exercise and can't eat anything. This is not hypocrisy. According to scientific analysis, this is mainly related to two points: ① strenuous exercise regulates hormones, reduces hunger hormones, increases blood lactic acid and blood sugar, and can inhibit hunger. (2) strenuous exercise increases the body's heat production and appetite. This is the same reason why animals instinctively eat more to resist the cold when the temperature drops. I have no appetite in hot summer.

2. Reasons for being particularly hungry after exercise: It is usually normal to be particularly hungry after exercise. Now, first of all, exercise can speed up the frequency of intestinal peristalsis, which leads to the rapid absorption of food in the gastrointestinal tract and becomes food residue, which leads to the accelerated gastric emptying, thus resulting in hunger. Secondly, while exercising, the body needs a lot of calories to maintain the consumption of exercise, thus accelerating the blood circulation in the gastrointestinal tract and quickly absorbing the nutrients in food, thus accelerating the digestion of food in the intestines, and may be particularly hungry after exercise. Finally, when hyperthyroidism occurs, because the basal metabolic rate of the body is accelerated, the body needs more calories and the intestinal peristalsis is also accelerated. Usually, if you don't exercise, you will feel hungry. When exercising, the body needs more calories, which will lead to faster intestinal absorption and produce a feeling of special hunger.

In order to suppress hunger, we must first improve our physical fitness and be able to complete high-intensity exercise. It is not easy to get hungry after high-intensity strenuous exercise. But only after an hour or two, the appetite can return to normal. Therefore, do high-intensity exercise two hours before meals; Eat snacks or drink milk before exercise to avoid hypoglycemia; Drink a small amount of water many times before, during and after exercise. High-intensity exercise is not suitable for long-term exercise, which may lead to bone and muscle tension. Only by persisting in exercise and improving muscle content and basal metabolism can we consume more energy. It is essential to eliminate fat. Generally speaking, the intensity of anaerobic exercise is larger, and the intensity of aerobic exercise is smaller. Can be combined with aerobic exercise. If you feel tired, you can have a rest.

At present, when greedy insects reach the brain, exercise or simple activities can immediately suppress appetite and divert attention. If you keep exercising for a long time, you will find that your mouth is no longer easy to feel lonely and your control over eating will become stronger. Don't let yourself feel a strong sense of hunger, and don't fight hunger.
