Is it a girl? Still a middle school student! ~! I don't advise you to lose weight now. It's still time to stretch. You'd better exercise more and try to control your diet. Eat less and eat more, and be full in seven or eight minutes. Eating too much will make your stomach swell. Don't eat snacks, fast food and other high-calorie foods and drinks! Breakfast must be full and nutritious, otherwise it will be easier to get fat! ~! It will also make memory decline.
Of course, you must lose excess meat. If you don't want to exercise, you can go to some slimming centers, but don't drink slimming tea, which is easy to rebound. I recommend you to go to the Mahua International Slimming Beauty Center in the UK, which basically meets your requirements, but it is expensive and you may not be able to afford it as a student. You can try.
