I used to be a little overweight, and I think the best way is to keep my body active: that is, to keep my body in a state of consuming more physical energy than usual. For example, go to WC during recess, don't take a leisurely walk, let yourself run over. Running is really a good way to lose weight. Although a little tired, if you can persist, you will find yourself falling in love with it! It can save you a lot of time to do more things you want to do. If you persist, it will be of great help to your health. Ha ha! Eat more fruits, especially apples, and let water replace drinks. Take part in more sports! Don't think it is inconvenient to be a girl! If you adapt, it will be of great benefit to yourself! I sincerely wish you complete your wish!
