'Biggest Loser' preview: Jillian Michaels returns for Season 14 to tackle childhood obesity

Season 14 of NBC's "The Biggest Loser" hopes to not only change the lives of the contestants competing to drop the most weight, but also to help tackle America's childhood obesity epidemic.  

"It's time to fight for our country's most valuable asset: our kids," says host Alison Sweeney in the sneak peek clip (below) of the new season, which premieres Sunday, Jan. 6.

And to help do that, the show is featuring three kid participants for the first time in the program's history -- Lindsay Bravo, 13; Sanjana "Sunny" Chandrasekar, 16; and Noah "Biingo" Gray, 13.

However, unlike the 15 adults from this season of "The Biggest Loser," the teens will not be doing the typical on-camera weigh-ins nor will they be eligible for elimination. The focus for the kids will be on getting healthy -- not numbers on a scale.

To help whip the contestants into shape, trainers Bob Harper and Dolvett Quince will be joining new mom Jillian Michaels, who says she was lured back in part because of the season's focus on childhood obesity. Each will oversee a team of five adults and one child participant who will compete with and contribute to their respective teams. 

Take a look at a sneak peek of what's to come this season.


The two-night premiere starts Jan. 6 at 9 p.m. with part two airing Jan. 7 at 8 p.m.
