Multiple three-day diet plans are available; each plan has the dieter consume a very low amount of calories per day, after which he typically loses several pounds. However, dieters typically gain back the weight lost on these plans that aren't endorsed by any doctors. Dieters should consult a doctor before beginning a new diet plan, especially one that severely limits calories.
One common version of the three-day diet offers a three-meal-per-day meal plan. One breakfast on this plan consists of half a grapefruit, one slice of whole wheat bread and 2 tablespoons of peanut butter. A lunch is 1 cup of cottage cheese, one egg and five crackers. A dinner is 1 cup of green beans, half a banana, one small apple, 1 cup of vanilla ice cream and 3 ounces of meat. The dieter can choose any type of boneless or skinless meat, such as chicken breast, turkey or lean beef.
The dieter consumes fewer than 1,000 calories every day on the diet. The plan recommends that the dieter drinks a large amount of water, although it also allows the dieter to drink black coffee or tea with some meals. It doesn't recommend exercise, as most dieters don't have much energy on this diet.
