I do what perna does and so far have lost 30lbs. Its pretty easy too, just dont go over your allowed amount, and you still can eat alot of things most diets would freak over. Plus You would be suprised on how much veggies and stuff you can eat on this method for keeping in the range and its good for you also. Only bad thing is the skinnier and lighter you get the less amount your allowed, LOL.

Good luck to you!
