Watched UK Chan 4's "Supersize vs Superskinny"
and found it kind of disturbing that they make people at the extremes switch diets. Heart attacks have been linked to a single high fat meal and they make people who have been eating crackers for 2 years suddenly sit down and eat a pile of cheeseburgers. Likewise someone who has type 2 diabetes can go into shock if they are forced to live with very low blood sugar.
They also use the United States as a punching bag by telling their contestants "if you don't stop you will wind up like this American." And they love saying that Evansville Indiana is the fattest city on Earth.
I have seen 3 episodes so far and they never seem to show what they SHOULD eat. They spend most of the episode showing food and over weight Brits and Yanks. Seems like the show could do some good if they actually went through the process of designing healthier diets that fit with these people's preferences.
They also don't deal with the psychological origins of the eating disorders so it comes across as just saying "you eat more, you eat less, problem solved." In many cases eating disorders, both anorexia and binge, are related to sexual trauma and binge-ing (sp?) can be related to a sense of loss and depression. The eating disorder is the symptom and not the underlying cause.
Here's a taste:
