If you go to just about any other country in the world, you'll be amazed at the lack of fatties compared to here.

It seems to be somewhat State related.
I spent a week in California's Silicon Valley area recently and there were very few fatties.
States like Texas and Georgia seem to have their share of tonnage.. ;)

You can go and ask your Chinese neighbours next door. Pop up at the Pacific Mall in Markham and ask anyone passing by what they think of the shapes of "white people". You will hear the Chinese migrants use exactly the same words you describe your American neighbours back on yourself.
