For the first time, a woman has won The Biggest Loser. Ali Vincent, a 32-year-old hairdresser from Mesa, Ariz., lost more than half her body weight during the show’s fifth season and won $250,000 for her efforts.

“I am a whole new woman,” Vincent told the Today Show's Lester Holt on Wednesday. “There are no limits. There are absolutely no limits and I started to dream big again.”

Although fellow contestant Roger Schultz lost 164 pounds, The Biggest Loser winner is determined by weight-loss percentage.

This being the "couples" version of the show, Vincent and her mother were voted off the show in the fourth episode and Vincent went on to lose another 33 pounds at home.

“I was like, ‘Nobody can take this away from me,’ ” she recalled. “I’m going to do it. I’m going to go back there and I’m going to stand on that stage, even if it’s with the at-home people, and I am going to be the Biggest Loser.”

However in the show's twist, she was brought back.

“I’m going to continue to go for what I want,” Vincent told MSNBC. “My physical being is a direct representation of what I feel inside, which is strong and confident and beautiful.”
