The Abs Diet - Fact or Fiction

I have started this new workout/diet program called the Abs Diet. I read the book and actually liked the idea behind the diet. Has anyone out there actually tried the Abs Diet and been successful. I am just now starting it. I dont have a lot of weight to lose but 15 pounds would be nice around the ole mid section. One thing is certain - I know I will save money by not eating out all the time. So maybe there is ONE definate benefit.
