File under newsflash: University of Pennsylvania researchers have found that counties with a higher concentration of fast food joints also have higher obesity rates:

"We found that there was an association between the amount of full-service restaurants (with waiters) in the county one lives in and a lower risk of obesity,' said Neil Mehta of the University of Pennsylvania.

"Conversely, we found that the increase in the number and the amount of fast food restaurants was associated with an increase in obesity,' he added in an interview."
