Fat Head

The production quality wasn't fantastic, it sounded more like a news piece than a movie, but it wasn't bad. I enjoyed it.

you can watch it for free.
I would like to get a response. Does anyone know how credible the movie is?
It seems quite credible to me. 3 documentarians have done a 30 day fast food diet and lost weight just to prove supersize me wrong.
In this movie he points out that even eating a supersized meal 3 times a day does NOT equal 5 000 calories, as Morgan Spurlock's nutritionist said.
It starts out saying that "supersize me" was a load of crap and basically couldn't have happened the way Spurlock and his nutritionist said, so he called the representatives of Spurlock and they refused to show his food log. In fact they have /never/ released his food log to any media.

This documentarian does a 30 day fast food diet and loses weight
then after that he does a 30 day heavy saturated fat diet and his health actually improves
it's kind of funny.
