Fire up your TiVo, clear your schedule and get ready to see double. NBC’s Biggest Loser Season 5 premieres January 1 and is bringing two-times the excitement as usual. This season, couples are taking on the weight loss challenge. Ten teams of two, including a mother/daughter, divorced husband/wife, married husband/wife, best friends, former football teammates and one team of complete strangers, will battle the scale and the bulge for a chance to win $250,000.

Jillian Michaels and Bob Harper will both return to coach teams in season 5; Kim Lyons is departing to focus her efforts on family and the release of her new book.

Stay tuned to Diets In Review for complete Biggest Loser updates.
