Junior high school courses are busy, and I don't think you have much time to do sports. Then the best way is to eat less and eat more ~! ~!
I don't know how your appetite is ~! But I suggest you eat normally every morning ~ eat as much as you want ~! You can eat some fruit before lunch (at most one) ~! Apple is the best ~! (Bananas and watermelons are not acceptable) You will eat much less than usual for lunch ~! Eat some snacks and fruits when you are hungry in the afternoon ~ but you can't eat anything with high fat content ~! It is best to use an apple instead of dinner, or eat only a small amount of vegetables instead of staple food ~! Never eat at night ~! Don't eat even if you study late ~
Do a set of sit-ups before going to bed, the number of times is up to you (until you feel sour after finishing your stomach)
This method focuses on persistence, and I can assure you that if you can persist for a period of time, it will definitely have an effect ~! And it has no side effects on the body ~ it has a good effect on reducing stomach. I tried it at school! ~
I hope you succeed. .......
