First, 1, ten minutes between classes. It is also a good time to exercise. Don't sit all the time during recess. Be sure to go outdoors, preferably where there are plants, so that you can breathe fresh air. 2. Around eight o'clock in the evening.

Third, according to the requirements of TCM health care, no matter how to lose weight, or in daily life, we should eat less dinner and speak clearly. Light means "less salt, less oil and less meat". You should pay attention: although you should eat less at night, you can't just eat fruit or milk as you said! Sampling is not conducive to weight loss! Because I have to study and exercise at night, I will be hungry before going to bed. If you can't control it for a while, you will inevitably add a little supper, which is even worse. Therefore, you should eat a certain amount of grain for dinner. I recommend you to eat: a certain amount of vegetables, rice porridge (preferably coarse grains), eat some fruit after one hour, and drink some milk (you can add some honey) half an hour before going to bed.
Fourth, it is normal to feel tired after studying. You should pay attention to the combination of work and rest. Every 40 to 50 minutes, stand up and exercise for more than ten minutes. Don't be too violent. Do some simple physical exercises, stretch, do some stretching exercises, especially the neck and back!
Fifth, it is not advisable to drink plenty of water immediately after exercise. It is better to drink some sugar water (such as some sports drinks) after ten minutes of exercise.
Note: Because junior high school students are in the stage of physical development, it is important not to advocate losing weight (unless the body exceeds the standard too much) to maintain a healthy body!
