Never heard of most of them.
I don't see the big deal about the Supersize Me one. The only criticisms seem to be (a) the calories don't quite add up to 5000 a day as one guy in the documentary said they did at one point (by my reckoning its more like 3,500-4000 - two big mac meals are 2,900, plus breakfast would add another 500-1000 depending on choice of breakfast - but a few milkshakes or apple pies could easily bring it up to 5000) and (b) the swedish team couldn't reproduce the liver damage claim.
Given you are supposed to only consume 2000kcals or so, the difference between 4000 and 5000 hardly seems critical.
The main issue I had with that documentary was just that it was bleeding obvious. Eat a full McDonalds meal three times a day every single day, you'll get fat and your health will suffer - who on Earth finds that surprising?
