A recent study suggests that obese workers negatively impacts profits:
Duke University researchers also found that the fattest workers had 13 times more lost workdays due to work-related injuries and that their medical claims for those injuries were seven times higher .
Overweight workers were more likely to have claims involving injuries to the back, wrist, arm, neck, shoulder, hip, knee, and foot than other employees.
The conclusion states that more employers should invest in programs to fight obesity. However, I think that data like this would make it that much harder for the obese to find a job.
