I've recently put an extremely overweight friend of mine on this exact diet. He has dieted in the past, lost some water, and ate his way back. Bottom line here is that this Diet is TOTALLY EFFECTIVE!.... He has not cheated once, and I refeed him every two weeks. He's about half way through and has lost 25 pounds. He looks absolutely fantastic, and has been losing a healthy amount of weight the past 2 weeks after the intial losses of water, transition, etc. In terms of the diet being ineffective due to the strcitness or wat have you.. that's complete bullshit. The Pb is great an is filling. Obviously it gets hard to eat only Pb and whey for 3 months.. but thats were discipline come into play. If you dont have balls to be discplined enough to stay on the diet, then u stay fat... simple as that. If you want it bad enough this diet will totally work for you. Not only are the macronutirent ratios effective for fat loss... but ANPB is an amazing food... you would not expect the same results from similar ratios from different foods. Also, obviously its a not a long term solution to everyone's fat loss goals- thats the thing- there is no one solution! This certainly helps though.
