This matches my feelings. I'm Australian and id say the average person is overweight but not very overweight. I don't know how common this is in the US but you see those photos of people in Walmart with fat hanging over both sides of the scooter and its something I don't think I have ever seen in Australia.
At least in my rural part of the U.S., you are likely to see one such morbidly obese person at any given WalMart at any given time of the day. But that’s unique to WalMart. You may see such a person at other stores, but something about WalMart attracts the morbidly obese. Then and pickups with lift kits and guys with camo ballcaps.
Walmarts are everywhere, there are thousands of them and millions of people in them every day. You're going to see the best and the worst just because of sheer numbers.
Not saying that the fatest American isn't fatter than the fatest Australian but "people of walmart" is a bit of a misnomer because you only need one picture of a fat person in a Walmart and there's literally millions of opportunities each day to see that one example.
Same thing in many US cities where walking is the norm.
The other major factor is wealth. Richer people can afford higher quality food. Poor people generally consume more calories from junk foods and sugary drinks, which are staples of drive-throughs and fast food chains.
I'd say the average misses the point here. That's quite a lot people! All addicted to sugar and fast food. This is a huge market. Same as the market for fighting the results of this unhealthy life style.
Yes but not by a very wide margin. [1]
Average BMI in the US is 28.5, Saudi Arabia is the same, Mexico is 28.1, New Zealand is 27.9, UK is 27.3, Canada is 27.2.
My point is that the impression that the US is unreasonably fat compared to the rest of the world is mostly just bias.
