>The other problem being the availability of healthy food. Those without the time or facility to cook are dependent upon stores selling convenience foods which are anything but healthy, those foods labelled as such being some of the worst examples.

Is it impossible to buy healthy food in your region? The average American spends six hours a day watching TV, do they really not have enough time to cook a meal? Just how many people do not have a cooker in their home? Is it cheaper to buy preprocessed food rather than the raw ingredients in that meal?

It seems to me the real problem is the supply of food is abundant and corporations have gone to extraordinary lengths to make it very palatable. Add in peoples tendency to chose the easy option (ready meals, eating out) and you get an obesity epidemic.
