Automobiles Cause Obesity

From "Study: Surge in obesity correlates with increased automobile usage" on ScienceBlog:

Junk food, video games and a lack of exercise all have received their fair share of blame for the spiraling epidemic of obesity in the U.S. But according to a University of Illinois researcher, public health enemy No. 1 for our supersized nation may very well be the one staple of modern life most Americans can’t seem to live without one (or more) of: the automobile.

Sheldon H. Jacobson, a professor of computer science and the director of the simulation and optimization laboratory at Illinois, says that the surge in passenger vehicle usage in the U.S. between the 1950s and today may be associated with surging levels of obesity.

“You can think of obesity as an energy imbalance,” Jacobson said. “People consume food, which is a form of energy, and then they expend it in their activities.

It is that energy imbalance that ultimately may lead to obesity.”
