I'm an Australian living in Germany. I'm surprised Australia is not on that list. I see very very few fatties here compared to back home. There are some, sure, but when you think Germany has a population of 80million, and Oz a quarter of that, there seem to be proportionally less overweight people here.
Unless they're all hiding in some far flung ex communist corner somewhere.
The biggest football stadium in my hometown in Australia had to replace all the seats a few years back because the fatasses weren't fitting anymore. That's a bit of an indictment I'd say.
