I see fat people here in Europe, but not on the sheer scale I've seen in the US. It's not that everyone is fat - I see plenty of Americans in good shape. It seems more about extremes, where hams in the US can become walking mountains of butter. I eat out most of the time when I'm in the US and often can't finish the meals. I order small or medium meals in fast food places because anything bigger than that is more like a meal for two. I routinely see people walking around with soft drink cups that look close to a litre in size.
