Unhealthy snacks lingering around the company office are derailing employees' efforts to stay healthy, a U.S. study finds.

A study investigating workplace eating habits sponsored by Peapod Business Delivery, shows that 63 percent of workers find it a challenge to eat healthy in the workplace. Seven percent ofrespondents report they eat healthier in the office than at home and workers cite unhealthy snack options as the number one obstacle to eating healthy while at work, the study says.

"One of the best ways to support healthy lifestyles in the workplace is also one of the easiest," said Cathy Leman, a Chicago registered dietitian and certified personal trainer. (Companies can) "Offer a variety of choices like fresh and dried fruit, yogurt, whole grain crackers, nuts, raw veggies with low-fat dip, hummus, baked pita chips and oatmeal raisin cookies."

The study shows there are major disparities in the workplace between what people want and what they are getting.

• 47 percent cite having too many tempting snack options in their workplaces as the top reason they are not able to eat healthy.
• 28 percent claim they are fully satisfied with the amount of healthy snack options provided to them in the workplace.
• The food employees want most in the workplace is fresh produce, but only 36 percent of companies regularly purchase fruits and vegetables.
• The food employees want least is candy, yet 1 out of 3 businesses provide candy to employees.
