America's Biggest Loser is my new favorite show because I find it very inspiring. I think it is incredibly brave for these people to get on a scale in front of the nation. They work out at least four hours a day. They endure temptation and humiliation. It makes me feel much better about my own weight loss struggles.
I don't really care for the "Survivor" style of having two teams compete against each other and having to vote people off. I think they should just all compete against each other equally and the trainers can determine each week who deserves to go. But that is just my opinion.
I find it fascinating and inspiring and highly recommend it even if you dislike other "reality" shows. This one isn't based on deceit at least.
