I gave it a go a while back and really didn't see anything dramatic. Another thing I didn't like about the AD was once I decided to come off. I gained a good bit of bodyfat by introducing carbs back into my diet. I really never knew about SLOWLY introducing them back in, and it was detrimental to my physique. However, I did see amazing results by combining The Zone with IF. I figured out my Zone blocks and ate them all in a 4-5 hour window. That was , without a doubt, the best I ever felt and looked.
