Trainers, what’s your take on the training/nutrition approach of the Biggest Loser TV series?

Well said Michael Schmid! I am not thrilled about how much weight loss is done in a week and the possibility of injury or even death. Also some of the challenges are stupid and dangerous.
I have had new clients come to me because they love the show and transformations. First thing I tell them that I am not Jillian (I do not scream and belittle) and they will not lose weight as quick as the people on the Biggest Loser. I let them know that I do not watch often, but would rather have an emphasis on fat loss/muscle gain or how previous clothes fit rather than weight loss.
