NBC has revealed the identities of the 15 adult contestants and three teen participants who will be appearing on the fourteenth season of The Biggest Loser, which will premiere with a two-night event on Sunday, January 6 at 9PM ET/PT and Monday, January 7 at 8PM ET/PT.

As previously announced, Jillian Michaels will return for The Biggest Loser's fourteenth season and the new edition will feature a twist in which teenagers will also be part of the cast.

Michaels will be joining returning trainers Bob Harper, whom she has worked alongside on every The Biggest Loser season she has participated in, and Dolvett Quince, who joined the show two seasons ago following her most recent departure, as well as host Alison Sweeney.

In addition to the 15 fourteenth-season adult contestants, The Biggest Loser will also be attempting to tackle childhood obesity by featuring a group of teenagers 13-17 years of age for the first time in the show's history. Childhood obesity expert and pediatrician Dr. Joanna Dolgoff will assist the kids in getting healthy and achieving their personal goals.

Similar to prior The Biggest Loser seasons, the adult contestants will be divided into three teams and trained by Michaels, Harper and Quince. However, each trainer and team of five adults will also "be paired with one child participant who will compete with and contribute to their respective teams," but the teens will not be eligible for elimination nor will they weigh-in on-camera, according to NBC.

Unlike the adult contestants, the teenage participants will also not be secluded on the ranch for the majority of the season, as they will have to take lessons learned on the ranch and apply them at home as well in their normal everyday lives. Their progress and transformation will be featured in each episode.

The show's three kid participants will be Noah "Biingo" Gray, who wants to be a professional baseball player and believes himself to be "a skinny kid trying to get out of a fat teenager's body;" Sanjana "Sunny" Chandrasekar, who takes Advanced Placement classes and enjoys singing and tennis but lacks self-esteem; and Lindsay Bravo, who once gave up her love of cheerleading because she was teased for her weight.

The three teen participants who will appear on The Biggest Loser's fourteenth season -- as well as their NBC-supplied bios -- are as follows:

- Lindsay Bravo, a 13-year-old eighth-grader from Fillmore, CA

- Noah "Biingo" Gray, a 13-year-old eighth-grader from New Windsor, MD

- Sanjana "Sunny" Chandrasekar, a 16-year-old eleventh-grader from Rochester, NY
