Fenton 3 Posted May 25, 2008 It all depends on how big you are (which determines how fast you'll burn fat), what your intake is, and how much exercise you're doing. I've lost at a bit more than 4 pounds a week since my surgery. On THE BIGGEST LOSER, where they exercise all the time, a 4 pound loss would be considered unimpressive. So it's really up to you.
