Claim: lose four to six pounds in three days

Theory: Clear stomach, low calorie.

Menu introduction: only once a month, for up to three days at a time. When you are hungry, you can only drink water, cheese or cook vegetables. Cheese should be low-fat or original.

Breakfast banana: a banana with cheese and a glass of mineral water.

Lunch banana: one banana with cheese and two glasses with mineral water.

Banana for dinner: one banana with cheese and two glasses with mineral water.

Truth: This menu lacks nutrients, such as iron, zinc, vitamin C, folic acid, vitamin B, vitamin E and so on. But it won't cause serious injury after three days. Eating bananas and cheese for breakfast is still healthy. In fact, plain cheese is not low-fat, so low-fat or skim cheese should be the first choice, because the protein and calcium contents of low-fat and skim cheese are the same as those of full-fat cheese except low-fat and low-cholesterol.

Safety: Do not use it for a long time.
