Celeb Weight-Loss Winners!

Kelly Osbourne's DWTS slim-down! John Goodman's 100-lb. weight loss! See how these stars battled the bulge – and won!

JOHN GOODMAN

At his heaviest, Goodman tipped the scale at 368 lbs., but when he graced the red carpet at the AFI Awards in June 2009, the Treme star was 100 lbs. lighter! Calling years spent on the couch "a waste," the 58-year-old actor is now committed to daily exercise, a sugar-free diet and an alcohol-free lifestyle. "I just ordered some nice slacks," he told PEOPLE. "I finally got them and they're too big now."
