I lived on the Abs Diet for about 4 years. I think it's a great all-around diet, and can help you achieve the results you want.
For the past 8 months, I've switched to a cycle-ketogenic diet to help my cut further and at the same time put on mass. For more information you can read Body Opus. The diet is very strict and meticulous, but it's enabled me to finally achieve the type of results i've always wanted.
Hope that helps.
