Jillian Michaels admits she worries about the heaviest contestants on The Biggest Loser.
When asked about the dangers of obese participants competing in tough physical challenges on the NBC show, the trainer tells Ladies' Home Journal, "You're the fifth person to say that to me this week. And you're not wrong. The contestants keep getting bigger and bigger."

The next season features four competitors who weigh more than 400 pounds, and one who breaks the show's record at 526 pounds.
Adds Michaels, 35, "As the trainers, we have no say over the challenges. We worry about them too."

The tough-talking fitness guru -- who will show off her softer side on her own show,
Losing It With Jillian Michaels -- says "The Biggest Loser is like a funhouse mirror.
"I've loved the show and the platform it has given me, but still, it is the nature of reality TV to manipulate," she continues. "You never see what's going on in its entirety. For every 10 minutes we're on the show, acting like insane people, there are a hundred hours of training you don't see. The stretching, the icing. Nobody wants to watch that."

Michaels also opens up about being an overweight, troubled teen.
"I lived on junk food. I had no direction," she explains. "Once I punched a hole in our wall. Another time I stole a car...."
She gained weight because "[my father and I] sort of bonded over food. When he was alone with me and we had nothing to say to each other, it would be like, 'Let's eat a pizza!'"
