How It Works
By some unspecified magical force, the combination of the suggested foods included in this plan is supposed to create a unique metabolic reaction and boost fat burning.
Without an author or book, there is no documentation or explanation of how the 3 Day Diet food combinations burn fat, increase energy, cleanse the body, or lower cholesterol.
As the name suggests, the 3 Day Diet lasts only three days, though it’s said that it can be repeated indefinitely, as long as you alternate with 4-5 days of undefined "normal eating." The purpose of returning to your usual eating style is to keep your metabolism from slowing, reverting to fat-storing, starvation mode.

What You Can Eat
The 3 Day Diet is a very specific food plan that must be followed precisely. Portions must be eaten exactly as specified and dieters are warned not to overeat — otherwise the promised 10 pound weight loss may not be achieved. Likewise, dieters should not under-eat, even if they are not hungry. The detailed plan does not mention or recommend any exercise.
