At 48, Helen Phillips has becomethe oldest winner ever of The Biggest Loser. The 48-year-old mom of three and grandma of five from Sterling Heights, Michigan lost 140 pounds over the course of the season. Helen lost 54.47 percent of her weight, enough to beat Mike Morelli of South Lyon, Michigan, and Tara Costa of New York City on the three-hour finale of The Biggest Loser: Couples, broadcast live from Hollywood on Tuesday night.

“It’s such a transformation for me. I feel so healthy. I feel like I’ve gotten my life back. I feel 30 years old again,” Helen exclaimed to TODAY’s Al Roker on Wednesday morning.
