Monstar-Last week my bodyfat was 9%.It's not because I eat like a supermodel,it's because my metabolism is about as fast as a championship racehorse with a hot poker up his ass.I've noticed it has slowed the past three years, and it is easier to put on weight now.I'm following Dr. Hatfield's zig-zag diet, and it does seem to help keep me lean.If I started to do cardio, I'd probably shrivel up.
