Nutrition should be reasonably matched, and foods with high fat content should be eaten less. The most effective way is to exercise more, especially don't sit directly after eating, which will make you gain the most weight! Eat more fruits and vegetables. But be sure to remember not to eat less or deliberately, because nutrition will not affect learning, and once it is not well developed, it will affect the future. We must be careful. In fact, in middle school, it is good to pay proper attention. When we go to college, we will lose weight, so that our physical development is complete. Appropriate cooperation with scientific weight loss will have a significant effect! I am a very successful example. If you need me, you can come to me. It's all personal experience.
