The most important thing is not to eat after five o'clock in the evening! Don't put up with eating Chinese food for breakfast. But you must hold back at night. Look at your school's dinner time, you can put it off later. I suggest eating less at night, otherwise you can't stand it. Because of the college entrance examination in senior three, I ate well. One-degree weight 150 kg. In my senior year, I lost 30 pounds in this way. I occasionally go running after self-study, but I don't insist. I know that the conditions of senior three are limited, and those so-called diet books can't come out at all!
