I watch Biggest loser to see the transformations and be inspired. Not much else. It's a tv show and I'm always shocked when people think they can obtain the same sort of results at home. We could never work out 6 hours a day, a week isn't a week on the show, and (for most people who I've talked to about it) they don't weigh 300 pounds.
I can understand why they don't give a lot of concret info on the show about exactly what they are doing. As unhealthy as some of those people are on the show I can see someone dying who attempted to do the same thing at home who isn't under 24 hour a day medical supervision
