As a result, the then-32-year-old Spurlock gained 24.5 pounds (11.1 kg), a 13% body mass increase, increased his cholesterol to 230 mg/dL (6.0 mmol/L), and experienced mood swings, sexual dysfunction, and fat accumulation in his liver. An intake of around 2,500 kcal within a healthy balanced diet is more generally recommended for a man to maintain his weight. He also walked about 2 kilometers (1.5 miles) a day.
Spurlock consumed an average of 20.9 megajoules or 5,000 kcal (the equivalent of 9.26 Big Macs) per day during the experiment. Spurlock ate at McDonald's restaurants three times a day, eating every item on the chain's menu at least once. It also explores the fast food industry's corporate influence, including how it encourages poor nutrition for its own profit and gain. The film documents the drastic effect on Spurlock's physical and psychological health and well-being.
Spurlock's film follows a 30-day period from February 1 to March 2, 2003, during which he ate only McDonald's food. Super Size Me is a 2004 American documentary film directed by and starring Morgan Spurlock, an American independent filmmaker.
