Kids Biingo, Lindsay and Sunny return to 'The Biggest Loser' and help White House nutrition expert Sam Kass judge cooking contest

Dolvett's red team gets inspired working out with motivational women from "Beat Cancer Boot Camp"

Season 14's popular kid ambassadors Biingo, Lindsay and Sunny return to the ranch to help White House nutrition expert Sam Kass judge a lively cooking challenge on the next episode of "The Biggest Loser," airing Tuesday, Nov. 12 (8 p.m. ET), on NBC.

Host Alison Sweeney introduces the remaining 13 contestants to Kass, the executive director of first lady Michelle Obama's Let's Move! initiative and senior policy adviser on nutrition. Kass talks about the importance of balance in a diet as well as eating fruits and vegetables daily. The task for the red, white and blue teams will be making a creative, tasty and nutritious dish that appeals to the whole family, including the toughest food critics of all - kids.

Helping Kass judge the dishes will be last season's kid ambassadors Lindsay, Sunny and Biingo, whose aversion to vegetables was well documented when he was a participant on last season's show. With only 30 minutes to prepare their healthy, kid-friendly dishes, the red, white and blue teams are off, racing against the clock and hoping to win the prize: a year's worth of groceries.

Also this week, Dolvett's red team is in need of motivation after losing beloved team member Ruben Studdard. So he plans a workout for them with the inspiring ladies from the "Beat Cancer Boot Camp," women who have either survived cancer or are going through it, who exercise together to stay motivated and healthy. It proves to be a very emotional and inspirational workout for all, especially contestant David Brown, who lost his first wife and the mother of his two children to cancer. 

Meanwhile, trainer Bob Harper encourages his players to continue to work hard and not rest on their laurels after winning previous challenges and weigh-ins, and Jillian Michaels helps one contestant overcome his fear of swimming in the deep end of the pool.

Biingo and his mom, Michelle, also visit with Jennifer, who hopes to help her overweight daughter get healthy. Michelle inspires Jennifer by sharing how her family was able to embrace a healthy lifestyle and lose more than 200 pounds together.

Finally, it's time for the weigh-in, where one player reaches a milestone, but another is sent home.
