NEW YORK (AP) -- Contestants on "The Biggest Loser" aren't just overweight. They suffer from being not normal and even half-dead.

That's according to Jillian Michaels, the buff, tough-talking trainer on the hit weight-loss show.

Michaels says she would never insult the plus-size people she is helping get in shape. But sometimes they need an extra push to get the lead out.

"You have to understand they're not a normal person," Michaels says. "These people are half-dead."

"The Biggest Loser" airs Tuesdays on NBC.
