Also, you can change the diet menu slightly and increase the amount of exercise. If you still don't lose weight.
If you are healthy, you should change your exercise style. Aerobic exercise is a long-term way to lose weight. Moreover, boys and girls have different constitutions. Girls have more body fat than boys, and they mainly burn fat during exercise. Boys have more muscle tissue than girls, and they may gain muscle during exercise. Generally speaking, it is to turn your fat into lean meat, and the metabolism of men and women is different, so the speed of losing weight is incomparable. For boys, it is best to burn fat faster and choose more vigorous exercise. Personally recommend ball games, you can have fun without spending money, there are all kinds of ball games, and you won't grow a lot of muscles in a targeted way.
There is also a possibility of not losing weight, called hypothyroidism, which is caused by thyroid problems, but this situation is relatively rare, and you can't lose weight without hard work, so it's time to check your thyroid.
The key to losing weight is persistence, and only persistence can see the effect. I wish you success ~
