The Biggest Loser Is A Woman

Season five of "The Biggest Loser" finally brought a woman to the winner's circle. Ali Vincent, who made a vow to return to "The Biggest Loser" after being voted out mid-season, made good on her promise after losing 111 pounds beating out both Roger and Kelly. I wonder if these people are capable of keeping off the huge amounts of weight they've lost in order to compete for a grand prize of $250,000.
