The rules of the Cleveland Clinic diet are: no altering prescribed amounts or substitutions, no snacks or seasonings other than salt or pepper, drink four glasses of water or diet soda daily, and resume a normal diet after three consecutive days, but no binging. Cheating makes the diet ineffective.
The Cleveland Clinic three-day diet is a rapid weight loss plan that dieters follow for three consecutive days. It is a very low-calorie diet that allows between 600 and 1,100 calories per day, and it specifies certain foods to eat on specific days. After the third day, the dieter can resume her normal diet, but may not binge. The process begins again next week until the desired amount of weight is lost. The diet requires strict adherence to be effective.
Proponents claim this helps dieters lose 10 pounds over the first three days or 40 pounds if it is followed for a month, and that it can be followed indefinitely. They also claim that it promotes better health because it detoxifies and cleanses the body, and that it is prescribed for overweight patients to lose weight before heart surgery.
Opponents claim that this is a fad diet and that any weight loss achieved is temporary and due solely to a reduction in carbohydrates and calories. They cite health risks associated with such a diet. The Cleveland Clinic, which publishes cookbooks and nutritional guides for diabetics and kidney patients, denies any association with this diet.
