No staple food! Fruit can't be too sweet! Eat some green vegetables every day, such as Chinese cabbage, mushrooms, rape, tomatoes, etc., and try not to eat them at night. I have another method, and my colleagues have tried it, but that diet is a bit bitter! Eggs and milk in the morning, half a bowl of rice at noon or an apple at night! The effect is obvious, but I suggest you be the first one, at least you can eat enough.
