Film records effects of eating only McDonald's for a month: Spurlock, a tall New Yorker of usually cast-iron constitution, made himself the guinea pig in this dogged investigation into the effects of fast food on the body. He ate only at McDonald's for a month - three meals, every day - and took a camera crew along to record it. If a server offered to super-size his order, he was obliged to accept - and to ingest everything, gherkins and all.
Neither Spurlock, 33, nor the three doctors who agreed to monitor his health during the experiment were prepared for the degree of ruin it would wreak on his body. Within days, he was vomiting up his burgers and battling with headaches and depression. And his sex drive vanished.
