yes, starving yourself is the worst thing you could do, your stomach will shrink.eat a little more than you normally would to stretch it out. im doing a test trial with 4lbs and 2 bakes potato's to make sure im prepared, then ill stuff myself the next day for thanksgiving, and ill be good. i know i can do it, and i know its going to suck afterwards, but the free 64oz steak.... so worth it.
