This kind of understanding is wrong, just like you wrap plastic wrap around your legs in the hope of stovepipe, which is contrary to the natural science of human body. You cover your body with a cotton-padded jacket, which will affect your normal metabolism. Some body wastes will not be discharged in time, but will affect your body shape and health. The best way is to keep a good mood, maintain good eating habits, go to bed early and get up early, believe in the self-regulation ability of the body, and let the body "slim down" by itself with abundant energy ~ ~

In addition, I recommend a good book "Manual for People".
