“The Biggest Loser” will return in January with the weight-loss show’s first young teen participants and trainer Jillian Michaels back on duty.

The show’s 14th season will take on a new “mission” against the national increase in childhood obesity, NBC said Tuesday. Youths between the ages of 13 and 17 will join teams trying to shed pounds and get fit.

Unlike adults competing for a $250,000 prize, the teenagers won’t be subject to elimination from the show and will not be weighed for the broadcast, NBC said.

Michaels had taken a break from the series to pursue the adoption of her daughter.
