"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... 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... His liver became toxic, his cholesterol shot up from a low 165 to 230, his libido flagged and he suffered headaches and depression... 'He was an extremely healthy person who got very sick eating this McDonald's diet,' Dr. Isaacs told The Post. 'None of us imagined he could deteriorate this badly - he looked terrible. The liver test was the most shocking thing - it became very, very abnormal.'"
