While I do agree that they should be explicit about how they get their results. It can't be good for people to get discouraged because they are not seeing what happens on the show happen to themselves. I do think that what is good about the show is that is does show that these people, most of them severly obese, can lose a lot of weight only using diet and exercise. When you see that as compared to shows that chronical someone who does GI surgery to lose weight..... I think no matter how quickly they take the pounds off on Biggest Loser, it must be more healthy than surgically mangling your GI tract. There seem to be few people who do the show who fail to get motivated and lose at least some weight, no matter how long they spend on the show. I think that it shows great results and I like the message that a person can be in control of their own wellbeing.
