There is a kind called Yangshengtang, which is said by Chinese medicine. Don't eat anything but water. First one day, three days, seven days. Like this. Drink millet porridge and bake steamed bread after crossing the valley. It is not advisable to eat more. This is good for the body, detoxification, health, temper the will!

Other ways: just eat pitaya, or just eat corn and only eat beef. Choose one out of three. Can't eat anything else. You can drink water to lose weight.

Besides, I took diet pills. I really don't recommend this. I'm worried about hurting my health.
