2468 Diet

With this diet, you eat 200 calories one day, 400 calories the next, 600 after that, and 800 for the last day, then the cycle repeats. People also commonly add a fast day after the 800 day, then repeat the whole cycle.
The diet is used by most people who want to loose weight fast and who want to keep it off. The purpose of it is to keep your metabolism guessing because all it knows is what was consumed the day before and doesn't know what the future holds.
Of course, like every other diet exercise must still be included. On average a person who abides by 2468 should loose 10 lbs per month.
