I think it is necessary for you to lose weight. Although you are only 13 years old, don't say you are 13 years old. Even if you are only 8 or 9 years old, I will still say this sentence. Sometimes obesity is not a matter of appearance, it will affect your health, and if you are fat, your physical fitness will decline, and then you will stop exercising, which often forms a vicious circle.

You are not fat yet, but your current weight is definitely not your ideal weight. You should check your eating habits first. For example: Do you like sweet things? Do you like fried things? Do you like salty food, and so on ... and then correct them one by one, and tell your family to cook with less oil and salt, light, eat more high-fiber vegetables and fruits, and eat less candy, cakes and carbonated drinks if possible. But you can't go on a diet. You can only eat normally. Just pay attention to supplement the sugar, fat and protein you need normally every day. Drinking 2000 ml to 3000 ml of water every day will help to remove toxins from the body, prevent bad breath and constipation, and people will be refreshed.

One more thing, exercise for at least 45 minutes every day, so that you won't continue to gain weight, or you will regret it if you really gain weight.

But don't eat weight-loss products. Many weight-loss products have side effects, and some of them are useless although they are boastful.
