It turns out jobs in public administration, utilities, and health care and social service have some of the highest populations of obese employees. A new study published in the American Journal of Preventive Medicine analyzed data from the 2010 National Health Interview Survey to determine Americans' weight, height, occupation and general stress on the job. The researchers found that employees who worked over 40 hours a week or worked in a hostile work environments were significantly more likely to be obese. People working in protective service, like cops and security guards were the most likely to be obese. But more surprising industries like health care had high numbers of obese workers as well, likely due to high stress and long hours.
