UPenn researcher puts a cost on obesity... btw, UPenn sucks.

Obesity -- which affects one in every three Americans -- and the illnesses associated with it cost the United States some 90.7 billion dollars a year in health care costs, a University of Pennsylvania researcher said.

Among developed countries, the United States has the most obese and overweight people, representing 66 percent of its overall population.

Costs tied to excess pounds (or kilograms) account for 5.04 percent of all US health care costs.
