Incredible Body Makeovers

"My life has literally been turned upside down," Stacey says of her weight loss. "It's a hard adjustment. People think that's going to be all great; it's not all great. It's a life to get used to, it's a new person."

As she continues to live in her "new" body, Stacey struggles to maintain a positive identity that reflects who she is now. "I never thought there could be anything harder than losing weight, but there is. And that is getting rid of that 500-pound voice in your head all the time."
