This is probably going to make some Americans mad, but you'll have to deal with it. As a European (not from UK though), I can't help but see what's defined as overweight here, is defined as normal by Americans.
I've not seen this once or twice. I've seen it, or heard it, a lot of times from Americans. Is it because so many Americans today are overweight that they think it's normal now? If you are what is considered normal where I live, Americans think you're a thin stick who'll break if you touch it.
Another example is sexual preferences. On American message boards, I often see people praising the huge asses of celebrities such as Kim Kardashian. And then they think that every ass that doesn't stick out 1 meter is "flat". I'm not saying Kim is fat, but her ass is.
Please note that I'm not saying that obese or fat are the new norms, but "overweight" is. In the US and UK, there are so many people overweiht today, maybe the society has begun to think it's normal and attractive? I mean, physical ideals change through time, that's a well known fact.
Is this just rubbish, or is there any truth to it?
