2. Keep walking for more than half an hour after meals. Exercise in the morning is not as good as exercise at night. As far as people's physical condition is concerned, sleeping all night, the body is in a state of water shortage in the morning, blood is sticky, and strenuous exercise may cause dangers such as insufficient blood supply to the brain, cerebral hemorrhage and myocardial infarction. If you like morning exercises, I suggest you drink 1-2 cups of boiled water after washing, and then exercise. From the environmental point of view, some toxic gases in the air are difficult to volatilize before the sun comes out, which is not suitable for exercise. From the follow-up reaction, it is easy to eat more after exercise in the morning, but it increases the intake.
Exercise after meals is mainly to burn excess calories in the body. However, it is not appropriate to exercise immediately after meals. At this time, the blood is concentrated in the stomach for digestion, and immediate activities affect digestion. It is advisable to go out for activities half an hour after supper. The ideal way to exercise is to walk fast, which lasts for more than half an hour.
3. Eat less sweets. Because sugar is easily decomposed or absorbed in the body, it is the main source of human heat. Most foods contain sugar, which has ensured your body's needs. Middle school students had better not abstain from eating sweets, because sweets can enhance memory.
4. Eat slowly. Chewing more when eating, chewing slowly, is not only conducive to the digestion of food by saliva and gastric juice, but also conducive to reducing eating. When food enters the human body and blood sugar rises to a certain extent, the appetite center of the brain will send a signal to stop eating and eat too fast. You have eaten too much before your brain signals you to stop eating. Therefore, the speed of eating should be slow, and 80% fullness is appropriate.
