The Biggest Loser USA

I'm growing increasingly aware of a lack of reality in the US's reality programming. Sitting down to watch The Biggest Loser USA I assumed I'd be watching some life-affirming pap where you see some large people struggle to change their lifestyles but eventually succeed and everyone goes home happy. Wrong. In this show they wave fatty foods in front of the contestant's faces while what looks like Linda Hamilton's transvestite brother/sister screams at them. Then the contestants bitch about each other in between being told all about the magic qualities of vegetables.
There's a level of humiliation at work here that goes beyond tough love or the school of wake up and smell the pancakes. This is coordinated and pre-conceived 'reality'. The real reality coming at the end of the show where someone is actually thrown out of the contest for losing the least weight. Not for putting on weight but for losing the least. What happens to the vanquished? Are they tossed back into their actual realities with the abuse of their trainers and other contestants ringing in their ears? Surely this can only lead to more self-loathing and relapse back into unhealthy lifestyles. In this case the biggest loser ends up being the viewer. For shame.
