I'm sure I'll get roasted for this, but here goes anyway...
I live in an area of London where pretty much nobody is 'overweight.' Particularly young people.
Last night, in Wembley Stadium (Harry Styles concert), the ONLY food available was chicken and chips or doughnuts. That's it. And - I know this will sound very judgemental - but I'd say about 7 / 10 people were quite 'overweight,' but all walking around in tiny shorts and cropped tops, etc (I know this is the vibe at this kind of event). It made me wonder if this is 'normal' for young people, on a national level? I know it sounds judgemental, but AIBU? Are most teens overweight where you live?
