Students, there is a very good way to kill two birds with one stone, and that is to study hard, because mental work is the biggest source of energy consumption. Anyone who devotes himself to study will study hard for five hours every day, provided that his nutrition can keep up with him and work and rest are combined. Believe me, it is not difficult to lose one kilogram a month.

I lost more than 20 kilograms in the year of college entrance examination.

Or, hurry to exercise, running is of course the best. If you feel too bored, men can play basketball and women can play volleyball.
