Disease analysis: Poor body shape and fat thickness are related to lack of exercise, too little exercise, unreasonable diet, less protein foods and more high-fat and high-energy foods. Guidance: If you want to lose weight, you should exercise more, such as running, dancing, playing ball and swimming. These activities will build muscles, reduce fat and change your body shape. Don't ride a bike if you can walk. More self-activity. Some studies say that if you sleep too little, you may eat more and get fat. So get enough sleep, don't sleep late and don't stay up late. In short, eat healthily and keep exercising.
