In the 2004 documentary Super Size Me, Morgan Spurlock decided to eat nothing but McDonald’s for 30 days. He ended up gaining lots of weight, suffering liver damage, and enduring intense mood swings. But now Spurlock’s movie has been repeated under experimental conditions. The results are good news for McDonald’s:
A Swedish researcher put 18 volunteers on the same diet that filmmaker Morgan Spurlock went on while filming “Super Size Me.”
To his great surprise, the researcher discovered that eating mass quantities of junk food affected each participant differently. While one volunteer gained 15 percent body weight after following the high-choleric diet for a month, several others experienced only minimal weight gain. [He] was thus forced to conclude that “some people are just more susceptible to obesity than others.”
The 12 men and six women were banned from exercising.
While all gained weight, none reported mood swings or liver damage like Spurlock did in the movie.
Update: Don’t rush out to McDonald’s for a quarter pounder yet. The story turns out to be a bit more complicated, as some of the subjects did have liver problems. See the astute comment below.
