Don't eat, exercise properly, sweat, defecate and wear thin clothes before physical examination (but be careful not to catch a cold). It is best to take a bath and rub your body with a bath ball, which can remove some dirt hidden in your skin and reduce 0.2~0.3 kg. It's already your best effort. After the physical examination, we should persist in exercising to lose weight and prepare for the next time. . . But be careful not to go on a diet! Classmate, you should eat at least a small bowl of rice just now, or you will be exhausted.

And don't drink diarrhea medicine, coffee and coke mixed together will not have diarrhea, that is a rumor, there is no medical basis. Don't drink diarrhea medicine, it's bad for your health.
