1, a reasonable diet: Pay attention to a balanced diet and don't be picky about food, because you are growing up and have a lot of studies, so you must ensure enough nutrition intake before you consider losing weight.
2, a good diet: I don't know if you will stay up late to study, if so, be careful not to be too late. Because it is too late, it is easy to get hungry, and eating after 9 pm is easy to get fat (PS: if you are really hungry, you can drink milk, which is easier to feel full, but it will not bring excess fat and help you sleep). You can run on the playground if you get up early in the morning. You don't have to run very fast, just jog for about 20 minutes. You can add soybean milk and steamed bread for breakfast, or change it into milk and steamed bread. Don't eat fried dough sticks, most of them are unsanitary. Remember to eat at noon. In some schools, the atmosphere is tense. The students try to eat as soon as possible. You must pay attention to this, and eat slowly when you eat. It's good for the body and image. Dinner can be light. If you have time after supper, you can go for a walk. On this basis, ensure the regularity of work and rest and have a good nap. Many people don't care about this. In fact, bad work and rest will lead to endocrine disorders and easily lead to obesity.
3. Amateur exercise: If you want to do amateur exercise at school, you should first push the flat support (originally, you want to say swimming, but it seems that students are not suitable for swimming, and it is ok to have time on weekends), right on your own bed. It doesn't take up space and time, and it can also exercise core muscle groups. You can do several groups of happy sweating before going to bed, then take a bath and have a good sleep. Physical education class and practice during recess are very active. Don't be shy, stretch yourself and dance to your heart's content.
4, a good attitude: keep a healthy and optimistic mood, your age is very beautiful, don't make yourself unhappy because of a little trouble, because 16 years old, others are too late to envy. For example, when I first joined the work, I was called uncle by my classmates aged 16. . . .
To sum up, eat well, sleep well, be in a good mood, and stick to it every day (it's very important, don't be on a whim).
