Personal trainer Jillian Michaels revealed on Tuesday morning that she will be making a return to "The Biggest Loser" for its 14th season. However, she will now be taking on the controversial subject of childhood obesity.  

The 37-year-old had elaborated to Al Roker and "Today" about the topic. The NBC reality fitness program will look to use the boot camp-esque Michaels in a more gentle capacity, as she will have to approach training the age 13 to 17-year-olds in a more mildly tempered fashion.

"You know, the show has chosen to take on something very controversial.  They're going to go after childhood obesity.  There are going to be three teenagers on each team.

"They're not going to be on the ranch, and they're not going to be competing.  It's obviously something that needs to be handled with kid gloves, but it's something that needs to be handled," she said.

Michaels, now a mother of two, also touched on all the behind the scenes leg work that has gone on to better prepare for the child version of "Loser."

"The producers of the show have been consulting some of the top experts -- pediatricians, child psychologists -- to help us deal with this in the most delicate and appropriate ways.  For example, we won't be saying things to kids like 'How much weight did you lose?'" Michaels explained. 

"It's about getting them healthy, using words like 'healthy.'  We won't be getting them on a scale; it's about getting them on a softball team -- things like that," she added.

Michaels had previously retired from "Loser" via Twitter on Dec. 7, 2010, stating that the eleventh season would be her very last.  She was last seen on the reality show in May 2011.  

However, she did get her own spin-off titled "Losing It With Jillian," which had run on NBC in June and July of 2010.

"The Biggest Loser" Season 14 will be premiering in early January 2013 on NBC.
