At least so they claim. This quote is particularly interesting: "One of the big contributing factors to obesity in this country is the increased access to unhealthy foods", Karen Inge of Jenny Craig. Bull!!! the main cause of obesity is lack of self-control, it's quite simple really the reason you're fat is because you eat too much for how much you exercise, it's not because someone makes food available for you, but because you choose to eat it. It's really not that hard to say, "No thanks, I'm on a diet, I don't need any more food."
