Biggest Loser Dangerous for the Participants?

Kai Hibbard, a finalist on the third season of 'The Biggest Loser,' reveals how dangerous she feels the show really is to its contestants.

When asked to clarify about her "a week is not a week on TV" comments, she said, "I'm saying that it would be, most times, longer than a week and I believe once, in my season, it was less than a week." (Contestants weigh-in on the show every week to determine who may get voted off.)

Hibbard also claims that the techniques they were taught to lose weight weren't always healthy. "The weight loss for that show is for ratings. People have to remember that 'The Biggest Loser' isn't a weight-loss camp that happens to be filmed for TV. It's a TV show that's made to look like a weight-loss camp. So there was pressure from production and everybody involved in the show to make sure you had as big of numbers as possible every week."
