Super Size Me is a 2004 American documentary film directed by and starring Morgan Spurlock, an American independent filmmaker. Spurlock's film follows a 30-day period from February 1 to March 2, 2003 during which he eats only McDonald's food. The film documents this lifestyle's drastic effects on Spurlock's physical and psychological well-being, and explores the fast food industry's corporate influence, including how it encourages poor nutrition for its own profit.

Spurlock dined at McDonald's restaurants three times per day, eating every item on the chain's menu. Spurlock consumed an average of 20.92 megajoules or 5,000 kcal (the equivalent of 9.26 Big Macs) per day during the experiment.

As a result, the then-32-year-old Spurlock gained 24½ lbs. (11.1 kg), a 13% body mass increase, a cholesterol level of 230, and experienced mood swings, sexual dysfunction, and fat accumulation in his liver. It took Spurlock fourteen months to lose the weight gained from his experiment using a vegan diet supervised by his future wife, who was a chef specializing in vegan dishes and gourmet.

The reason for Spurlock's investigation was the increasing spread of obesity throughout U.S. society, which the Surgeon General has declared "epidemic," and the corresponding lawsuit brought against McDonald's on behalf of two overweight girls, who, it was alleged, became obese as a result of eating McDonald's food [Pelman v. McDonald's Corp., 237 F. Supp. 2d 512]. Spurlock points out that although the lawsuit against McDonald's failed (and subsequently many state legislatures have legislated against product liability actions against producers and distributors of "fast food"), much of the same criticism leveled against the tobacco companies applies to fast food franchises whose product is both physiologically addictive and physically harmful.

The documentary was nominated for an Academy Award for Documentary Feature.

It has been reported that a comic book version of the movie is in the works with Dark Horse as the publisher.

Probably one of the most boring and incredibly bias insights into 'Fat America'.

F - worst film of 2004
