One food diets may be based on grapefruit, egg, poultry, melon, banana, steak, beer, yogurt, rice, or some other food. Dieters are allowed to eat as much as they like of their chosen food, but other foods are either prohibited or severely restricted. The diet is usually supplemented with multi-vitamins and dieters are advised to drink plenty of fluid. The diets appear to be designed to reduce food intake by being boring. They generally do no harm (and no good) because they are so boring that dieters usually give up after a few days. Nevertheless, one food diets are potentially dangerous if taken for a long time. Despite supplementation, it is virtually impossible to obtain a proper balance of nutrients from one food.
