Which Celebs Lost Weight on Dancing with the Stars?

Dancing for the Mirrorball trophy proved rewarding for more than just the winners of Dancing with the Stars.

Kristie Alley, Joey Fatone and Chaz Bono all lost weight when they put on their dancing shoes for the ABC reality competition show. Alley is perhaps Dancing's biggest loser, as the diet and exercise routine she used on the show ultimately led to her losing 100 pounds!

"I feel like I'm back in my element," she told Entertainment Tonight. "I honestly didn't even realize what I looked like. ... Before Dancing with the Stars, I bought these dresses from size 14 to 4. And I said, 'You know what I really want? I really wanna be in this dress in a 4!'"
