I have to reduce the intake of staple food these days, but I can't eat it at all. Eat apples two hours after meals, and indigestion immediately after meals. You can have porridge for dinner and then eat some apples. You must eat a small amount of staple food for breakfast and lunch to ensure a normal life for a day.

Stick to it for seven days, and you should be able to lose 3 to 5 pounds. But this long-term eating is not good for your health and is not sustainable.
