If an all alcohol diet is not recommended, then doesn't that seem like a direct contradiction to the principles?
Bast, I've been dieting and my delts look slightly rounder and fuller. Now I know I haven't gained mass on a restricted diet, yet my muscles look the same in terms of size and are actually more detailed. That's how I know I haven't lost anything. If Matt feels like he's lost a sufficient amount of size, then he has every right to be concerned.
