CareerBuilder's annual workplace survey measured an increase in the number of workers who reported losing weight while employed, according to company officials.

Slimmer waistlines were reported by 18 percent of those surveyed, which is up from 16 percent last year. The increase is being attributed by CareerBuilder, in part, to less stressful work environments. However, there are many other factors that contributed to these positive results.

Conversly, sitting at a desk all day was picked as the most likely cause of weight gain, but constantly getting take-out was also named as a culprit.

As vice president of human resources for CareerBuilder Rosemary Haefner points out, there are steps that can be taken by both the individual and a company to curb unhealthy habits. Haefner further points out that creating a healthy company culture can reduce overhead.

"Most organizations are mindful of the higher costs, both to their bottom line and to their workers' overall quality of life, that are associated with unhealthy behaviors," said Haefner. "As a result, many workplaces are taking a more proactive role in their staff's well-being by implementing programs and benefits that promote wellness."

One easy way to promote a healthy workforce is to chose a health insurance plan that offers services like fitness club reimbursements and nutritional counseling.
