Super Size Me (2004)
Morgan Spurlock sets out to eat nothing but McDonald’s for 30 days – and if he’s asked if he wants to supersize, he has to. This engaging documentary shows how fast food chains serve up portions of bad health just to make a buck. Unsurprisingly, Spurlock’s body isn't “lovin' it” after consuming 5000 calories a day for a month. Caution: Super Size Me will put you off junk food for at least an hour.
