After 5 seasons, Ali Vincent is the first woman ever to win on "The Biggest Loser." Ali lost over half of her body weight! That is an incredible accomplishment. I know, because ever since I was separated from my Siamese twin, Helen, I feel much more fit and agile. Ali will tell us all about conquering the biggest challenge of her life and I can't wait to meet her... I mean, what's left of her. Tune in to my show tomorrow to see her amazing transformation!
