This show is about weight loss and about gaining knowledge. Knowledge that you "can" do anything once you set your mind to it, knowledge of how to maintain what these people are working so very hard to achieve. I don't view them as "these poor people" as a poster above did because if they were really that unhappy or felt like they were being used to poke fun at then I don't think they would stay with the program. Obviously, something that is being done or said during this entire process is sticking with these people since these before and after shots are pretty awesome.
As for those who don't like watching the weigh-ins because of the topless men...quit watching.
