Watch the movie "Super Size Me".

Super Size Me is an AcademyAward-nominated 2004documentaryfilm, directed by and starring MorganSpurlock, an Americanindependent filmmaker. It follows a 30-day time period (February 2003) during which Spurlock subsists exclusively on McDonald'sfastfood and stops exercising. The film documents this lifestyle's drastic effects on Spurlock's physical and psychologicalwell-being and explores the fast food industry's corporate influence, including how it encourages poor nutritionfor its own profit. During the filming, Spurlock dined at McDonald's restaurants three times per day, sampling every item on the chain's menu at least once. He consumed an average of 5,000 calories (the equivalent of 9.26 BigMacs) per day during the experiment.

Before launching this experiment, Spurlock, age 32 at the time the movie was filmed in 2003, ate a varied diet but always ate vegan evening meals to appease his girlfriend (she is a vegan chef), was healthy and slim, and stood 6 feet 2 inches (188 cm) tall with a body weight of 185.5 lb(84.1 kg).After thirty days, he gained 24.5 lb (11.1 kg), a 13% body mass increase, and his BodyMass Index rose from 23.2 (within the 'healthy' range of 19-25) to 27 ('overweight'). He also experienced moodswings, sexualdysfunction, and liverdamage. It took Spurlock fourteen months to lose the weight he gained.

Impact:::  Subsequent to the showing of the film at the 2004 SundanceFilm Festival, McDonald's phased out its Supersize meal option and began offering healthier menu items in addition to its customary fare, though McDonald's denied that this was in reaction to the movie. The corporation did, however, issue a press release on their website, denouncing Spurlock's film and blaming the filmmaker for being a part of the problem, and not the solution.
