a day in McDonald's, trying everything on the menu at least once. Furthermore if he was offered a 'supersize' meal, he had to accept it.
Morgan Spurlock ate nothing but fast food for 30 days
At the beginning of the documentary, Mr Spurlock, who was 6 feet 2 inches in height and in good health, weighed 185 lbs (just over 13 stone). After 30 days, he had put on 25 lbs. However the overall effect on his health proved to be far more worrying than his increasing size.
Doctors who examined him, including a cardiologist, were shocked at how fast his body deteriorated. Within a few days, Mr Spurlock was vomiting up his meals. His liver then became toxic and his cholesterol level increased significantly.
He experienced headaches, depression, a lower sex drive and poor skin. He also said his knees began to hurt because the extra weight was going on so quickly.
Throughout the 30 days, he spoke to people across America, including ordinary people on the street, supporters of the fast food industry and health experts. He also attempted to get an interview with a McDonald's representative. However none would agreeto be interviewed on camera.
He returned to normal health after giving up his McDonald's diet.
