1, 3 days before crossing the valley. Eat nothing, drink at least 800ml of raw water every day, and drink slowly in small cups. After 3 days, if you can continue, you can eat some fruits and vegetables (mainly apples, tomatoes and cucumbers), but not more than100g each time. Don't eat anything, but you must drink more than 800ml of water.

2, the official broken valley stage. You can eat a certain amount of porridge, vegetable soup, peanuts, vegetables, fruits and other foods. Mainly used for people who are not suitable for completely avoiding grain, such as obese people.

Giving up is more important than starting. After officially breaking the grain, you can't return to normal diet immediately, but you should eat liquid food for three to five days, otherwise you will hurt your stomach because you don't eat for a long time. Many people have no effect, and even lead to body turning back, because they don't know how to quit the program and go back to their previous eating habits directly.
