More driving equals more obese

According to a Provo (UT) Daily Herald article, a study of over 10,000 Atlanta area residents found that for every 30 minutes more time residents spent in an automobile each day, there was a 3 percent higher chance of being obese.
The survey also found that people who lived within walking distance of shops -- less than a half mile -- were 7 percent less likely to be obese than their counterparts who had to drive.

"The more driving you do means you're going to weigh more -- the more walking means you're going to weigh less," said Lawrence Frank, associate professor at the University of British Columbia who oversaw the study when he worked at Georgia Tech.

That much seems obvious, but researchers were surprised to discover that how much time a person spent driving had a greater impact on whether a person was obese than other factors such as income, education, gender or ethnicity.
