I really hope they don't put Erik back on the show next season, or if they do they make him ineligible for the prize since he already won it. It will be good for him to get the weight off, but I think Bob is right, he needs to find a way to do this in the real world. I didn't see that season. Was he a big game player, the kind who is only in it for the money?
As for the article about Kai, again, I didn't see that season, but honestly, it sounds like she had no common sense. All the things she whined about should be transparently obvious to anyone who has ever watched the show. Complaining about people being lined up on treadmills? Did she even watch the show? It sounds like she already had the mentality that could lead to an eating disorder and it did push her over the edge, but that is not the Biggest Loser's fault. It's not for everyone, and it certainly is an extreme way of losing weight, but for some people it is exaclty what you need. If you have seen the show, you know what you are getting into.
