Why is it that so recently people are becoming so obese?

Obesity is a multifaceted problem in this country. Life is increasingly sedentary....more people sitting at their computers than are out and about and excercising. Fast food....the rise in clinical depression...blaming the healthcare system is like blaming firefighters for not preventing an arsonist from doing his thing, and makes about as much sense. In many areas, it simply isn't safe to leave your house. There are a lot of reasons why the weight averages are climbing. Primarily, the blame has to rest with the individual, if you just must place blame anywhere. Each of us makes a conscious choice to overeat or not. Very few insurance companies will cover the cost of bariatric treatments, like gastral byp surgery....or physician supervised diets for that matter...you might blame them too. I would suggest that lobbying your government to force adequate healthcare coverage at an affordable price might be one way to be part of the solution, instead of just sitting and pointing your finger.
