The contestants get to bid on the percentage of body weight they think theyll lose this week, and the highest bidding team can win $10,000 -- but only if they reach their weight loss goal. Then its off to a wild sprint and slide challenge, with the winning team earning a phone call home. Later, Chef Rocco DiSpirito drops by to teach the contestants how to shop for and make healthy, tasty and affordable meals before an elimination round sends another team packing. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.

America's vote is revealed and the third finalist is announced; one of the finalists is named this season's "Biggest Loser"; a sneak preview of season seven.

It's the last episode before the season finale, and time for the final four contestants to reflect on their weight loss journeys and the amazing progress they've made. They'll try on their former "big" clothes and watch highlight videos with their trainers showing just how far they've come. Then, in their final challenge of the season, the contestants will have to carry all the weight they have lost as they race around a track, shedding one week's weight loss at each pit stop until they cross the finish line. Later, at the final weigh-in, two players fall below the yellow line, and then make their heartfelt pleas to viewers as America will once again decide which of the two will become the third finalist at the season finale.

It's all about families in the new edition of The Biggest Loser, which features four husband-and-wife teams and four parent-adult child teams trying to lose weight through diet and exercise as they compete for a grand prize of $250,000. Trainers Bob Harper and Jillian Michaels fly around the country, surprising their teams with the news they've been chosen for the show. Then it's off to The Biggest Loser ranch in California, where the contestants get a wake-up call from the show's doctor about what ages their bodies really are vs. their chronological ages because of obesity. Then the eight teams compete in their first challenge -- and the lucky winner gets immunity from this week's elimination. Alison Sweeney hosts the hit weight loss series.

It's Thanksgiving week at the "Biggest Loser" ranch, and contestants will be celebrating with turkey, football and very special guests!

Then celebrity chef Rocco DiSpirito helps the contestants make a healthy version of a traditional Thanksgiving dinner. Later, the contestants are really thankful when they receive special videos from home. Alison Sweeney is the host, and trainers Bob Harper and Jillian Michaels also star.
