LAST February, Morgan Spurlock decided to become a gastronomical guinea pig.
His mission: To eat three meals a day for 30 days at McDonald's and document the impact on his health.
Scores of cheeseburgers, hundreds of fries and dozens of chocolate shakes later, the formerly strapping 6-foot-2 New Yorker - who started out at a healthy 185 pounds - had packed on 25 pounds.
But his supersized shape was the least of his problems.
Within a few days of beginning his drive-through diet, Spurlock, 33, was vomiting out the window of his car, and doctors who examined him were shocked at how rapidly Spurlock's entire body deteriorated.
"It was really crazy - my body basically fell apart over the course of 30 days," Spurlock told The Post.
His liver became toxic, his cholesterol shot up from a low 165 to 230, his libido flagged and he suffered headaches and depression.
