Corey Harrison is half the man he used to be. Four years ago the 31-year-old reality TV ‘star’ weighed more than 400 pounds. Today he’s just 200 and change, and in a whole new place in life. Diet and exercise? Not exactly, though these help–Harrison had the increasingly popular Lap Band surgery after his doctor warned him that diabetes was surely coming his way. Harrison told People magazine that he paid for the surgery with four credit cards. He didn’t have the money but he knew it was “something I had to do–I was not going to get diabetes.” Now he can’t just see his toes, he can touch them. And Harrison says he’s in the gym all the time–boxing!

Harrison lost 50 pounds in a week after the surgery, but the rest comes off in time–with dietary adjustments and the increased ability to exercise. Harrison may still play the heavy when it comes to negotiating a price on ‘Pawn Stars‘ but he’s lighter at heart. Other notable people who have had weight loss surgery–Lap Band or gastric bypass–are New Jersey Governor Chris Christie, Blues Traveler lead singer John Popper, TV personality Al Roker, singer Carnie Wilson, American Idol‘s Randy Jackson, comedian Roseanne Barr and New York Jets Head Coach Rex Ryan.
