he obesity rate in America is skyrocketing, and according to new statistics from the Campaign to End Obesity, along with increased health risks and health care costs for those struggling to control their weight comes a huge economic toll on the U.S. With hospitals widening bathroom stalls for severely overweight patients, and the Federal Transit Administration testing new steering and breaks on mass transit systems because of an increase in the number of heavyset riders, the estimated national cost of accommodating obese citizens is approaching $190 billion a year. Here's a look at some unexpected financial costs of obesity, by the numbers:

$190 billion
Estimated economic cost of obesity in America, or twice the amount previously estimated, taking into account everything from "wider stadiums seats to sturdier, floor-mounted toilets," says CBS News. The calculations were published in the Journal of Health Economics.
