This is the documentary that caused a sensation at Sundance 2004 and allegedly inspired McDonald's to discontinue its "super size" promotions as a preemptive measure. In it, Spurlock vows to eat three meals a day at McDonald's for one month. He is examined by three doctors at the beginning of the month and found to be in good health. They check him again regularly during the filming, as his weight balloons 30 pounds, his blood pressure skyrockets, his cholesterol goes up 65 points, he has symptoms of toxic shock to his liver, his skin begins to look unhealthy, his energy drops, he has chest pains, and his girlfriend complains about their sex life. At one point his doctors advise him to abandon McDonald's before he does permanent damage. The doctors say they have seen similar side-effects from binge drinkers, but never dreamed you could get that way just by eating fast food.
