When "The Biggest Loser" returns to on January 6, it won't be just for the two-hour debut of "The Biggest Loser: Couples." Rather, the weight-loss competition's first-ever woman winner Ali Vincent will make her QVC debut showcasing "The Biggest Loser" line of healthy lifestyle products at 10 p.m.

"I am excited to appear on QVC and help others achieve their health goals," Ali says. "I know that making lifestyle changes, no matter how big or how small, is a difficult process. 'The Biggest Loser''s products take the guesswork out of the decisions we make and help us stay on track."

Among the products that Ali, who lost 112 pounds during her tenure on the show, will be selling are: "The Biggest Loser" 30-Day Jump Start, a day-to-day planner designed by "The Biggest Loser"'s fitness and nutritional experts, "The Biggest Loser" Stability Ball with Resistance Band and two DVDs and "The Biggest Loser" Body Fat Digital Scale.

"The Biggest Loser: Couples" premieres on NBC on January from 8 to 10 p.m. Ali makes her QVC debut immediately following at 10 p.m.
