There is a paradox between the company always telling people to get "fit" as part of the HR/health insurance message, and then all of the free soda in the fridge, and donuts, bagels, and barbecue handed out all the time. If you don't have much willpower, you will have to watch your waistline. The treats are pretty constant. Also, especially among the older employees, there is a pretty strong resistance to change which is annoying when trying to make even small changes.
