In an interview with Parade, Michaels revealed that having children of her own opened her eyes to the importance of family fitness, and inspired her to help other young people who are struggling with obesity.
"There are a lot of reasons [I came back]. Obviously the show is dealing with kids, and having this huge platform to get the message and information out is invaluable," she explained.
"Everyday fans of the show were like, 'Please come back to Loser, please come back to Loser'. If I can find the time to do the things I want to do personally like run my business, be a mum, and still please the fans [then I will]."

Michaels continued: "I went to see Madonna in concert, and she played all this music. And you're like, 'This is great, but can you play Holiday now?' Biggest Loser is kind of my 'Holiday'. It's something you can't ignore."
Biggest Loser host Allison Sweeney recently admitted that she was "moved" when Michaels changed her approach to training.
The Biggest Loser airs on Mondays at 8/7c on NBC.
