Are posh people thinner?

Zoe Williams writing in today's Guardian praises Delia Smith for her retro-style. Slightly too formal wear and never licking a spoon or using 'just a bit' of something. Quite right, too (Nigella's last series, which involved her going to the fridge in the middle of the night to eat cold custard straight from the bowl bordered on the obscene).

Then this:

She mentions the fact that double cream is highly calorific, and therefore should only be used as a special treat (it has become very unfashionable to admit that some food is more fattening than other food. I suspect this is a snob thing; that rich people don't do it because they are kept thin by, I don't know, horseriding, bone structure, inadequate central heating . . . If rich people don't do it, then it is not posh, and the rest of us shouldn't do it).


Again, it's someone confusing 'posh' with 'snob' but I don't mind. It's quite funny here. It's also alluding to the idea that we all would rather be seen to be doing what posh people do.


I do actually think that people were a bit thinner in the old days partly because their houses were so much colder, especially those who lived in draughty country houses. I.e. the posh.


Think I'll turn the thermostat down today and then I can have scones with cream and jam for tea.
