Actually this method is wrong and unscientific. We should use scientific methods to lose weight. Pay attention to diet and exercise is the best way, and pay attention to sleep. However, we should not be lazy in bed. You'd better not eat anything after 8 o'clock. If we really want to eat, we can eat some fruit. By the way, fruits and vegetables are very good things, and it is not impossible to lose weight without eating meat. Eat lean meat properly, so that the system will be good and the weight loss will be more scientific and effective.
