This one is called the 17 Day Diet.  I don't know if it works, lots of folks claim it does.  I guess you having nothing to lose (except weight) and 17 days. It's all about what and how you eat and making your body process the foods you eat differently.

Dr. Moreno, a Kaiser Permanente family medicine doctor from San Diego, says that his diet is different because it doesn’t deprive dieters or restrict calories.
