Reality TV

I am surfing thought the channels, and for some reason stopped on the show Shaq's Big Challenge. It's basically about 6 fat, sedentary kids that are trying to lose weight and be more active/healthy. I know that these reality shows are about ratings and making money, but it seems to me that if a reality show is going to exist at all, one like this that at least helps a few people is the best we can hope for.
