Why are Americans so fat? Two words: fast food. What would happen if you ate nothing but fast food for an entire month? Filmmaker Morgan Spurlock does just that and embarks on the most perilous journey of his life. The rules? For 30 days he can't eat or drink anything that isn't on McDonald's menu; he must wolf three squares a day; he must consume everything on the menu at least once and supersize his meal if asked. Spurlock treks across the country interviewing a host of experts on fast food and an equal number of regular folk while chowing down at the Golden Arches. Spurlock's grueling drive-through diet spirals him into a physical and emotional metamorphosis that will make you think twice about picking up another Big Mac.

What would happen if you were to eat only food from McDonald's for an entire month? That question is answered in this controversial--and wildly entertaining--documentary from writer/director Morgan Spurlock. Subsisting solely on meals purchased at the Golden Arches for 30 days, Spurlock chronicles the shocking effects his new "McDiet" has on his body and mind, while also slyly commenting on America's "growing" obesity problem.

Two out of three Americans are overweight or obese, but where does personal responsibility end and corporate responsibility take over? On the heels of recent lawsuits against McDonald's, director Morgan Spurlock takes a hilarious and often terrifying look at the effects of fast food on the human body. Spurlock spends a month of eating nothing but McDonald's food, ordering everything on the menu at least once and "super-sizing" his order if asked.

Filmmaker Morgan Spurlock, rejected five times by the USC film school, won the best director award at the 2004 Sundance Film Festival for this alarmingly personal investigation into the health hazards wreaked by our fast food nation. Under extensive medical supervision, Spurlock subjects himself to a steady diet of McDonald's cuisine for 30 days just to see what happens. In less than a week, his ordinarily fit body and equilibrium undergo dark and ugly changes: Spurlock grows fat, his cholesterol rockets north, his organs take a beating, and he becomes subject to headaches, mood swings, symptoms of addiction, and lessened sexual energy. The gimmick is too obvious to sustain a feature documentary; Spurlock actually spends most of the film probing insidious ways that fast food companies worm their way into school lunchrooms and the hearts of young children who spend hours in McDonald's playrooms. French fries never looked more nauseating.
