I think there are two good ways to lose weight, 1, diet control; 2. It's exercise. Both methods are a test of your will. If you believe you can do it, please read on.
The first method is to control the daily intake below the consumption, so that the body fat can be converted into capacity, thus achieving the effect of losing weight. My suggestion is that you eat five meals a day. Don't think that eating so much will make you fat. Don't worry, I'm asking you to eat more. You haven't eaten for two to three hours since your first meal in the morning. You may think I have to go to work and school to get so much food. In fact, you can bring something, such as milk and fruit, that's all. Eat less fried foods with high fat and cholesterol, and replace them with protein cellulose (chicken, beef, fruits, vegetables, etc ...). You don't have to avoid sugary chocolate. You can eat some before and after exercise. Especially the first method, girls seldom do it, because most of the girls I meet like to eat snacks. This is a big black hole. It is not easy to resist the temptation of snacks. See if you want to eat or be beautiful.
The second is exercise. Of course, aerobic exercise is the main way to lose weight. There should be 60 to 45 minutes of exercise every day, which can be running, skipping rope, running and so on. It will be better if you swim. You can practice three days a week at first, and then you can add more slowly. Remember that haste makes waste, and health comes first. It will be better to keep changing the speed during exercise.
The above two methods will work better together.
