There was a recent worldwide survey I read on the BBC news about obesity related deaths and although the USA was predictably high up on the list it did point out that the scales were very much area related with poorer areas and States being higher on the death list than those places which had more wealthy folk.
the UK didn't do so clever either, in that survey.
