I gotta agree with you. Four years ago, I was just over 300lbs, and I looked MUCH beefier -- make that FATTER! -- than Pratt's 'before' picture. If his claim is accurate, that's the trimmest 300-pounder I ever saw!
P.S. I lost 120lbs with Weight Watchers and look a heckuva lot better now...
Congrats!
