Fat Head is a highly entertaining and informative (albeit zero-budget) documentary by a guy named Tom Naughton, who decided to try Spurlock’s experiment for himself. Naughton ate nothing but fast food for 30 days, but with two important caveats:

1. He didn’t eat whatever the clerk suggested, as Spurlock did. In other words, no super-sizing if he didn’t want to.

2. He kept his carbs to under 100 grams a day and his calories to under 2,000, using publicly available nutritional information about all the national fast-food chains.

Why these two important differences? As Naughton puts it, “Because I have a functioning brain.”
