Run, take time out to run for about 30 minutes in the morning. Do more aerobic exercise. Don't eat anything high in fat. Running is quite effective. But you can't see it from the outside, but it's really reduced. Jumping rope can also be done, and the whole body moves together, including chin, legs, next door and so on. In short, do more aerobic exercise. Not much can be done every day. But stick to it. Also, remember not to take medicine during development. Drugs are generally fake.
