The Biggest Loser's Tara Costa is charming, down-to-earth and eager to shed those pounds.  Costa gained 110lbs from May 2006 to the start of the show, but wasn't quite sure what attributed to the gain.  She told Life & Style magazine,

"I think there were many factors — leaving college, starting a new job, being in a relationship that wasn't the best for me," says Tara. "I don't think I was a happy person. I'm realizing that more now as I lose weight."

Before she was in front of tv cameras, Costa was in front of photographers as a plus size model.    

"I wouldn't want to take pictures because I knew that once I saw them, the truth would be in front of my face.  I was in complete denial. I only wanted to see myself as I once was."
