Yes, people are bigger now. Does that mean that people in the past (or people living in France, Spain, Italy, any country except the US because they are ALL fat bastards and the root of the world’s problems, yes?) were/are wiser, more abstemious, more sensible, more feminine, less greedy, less uncontrolled, less prone to ‘stuffing themselves’, etc.?
Of course not, and the implication that British people now (not us, of course, finger wagging posters with our 26 inch waists and self control!) are greedy, lazy gluttons waddling between branches of Greggs, Starbucks and McDonalds in their elasticated waisted tracksuits labelled size 16 - a size 32 in old money, the deluded fools - and are, in fact, a different species to the stoic, self-disciplined people were alive in the 1950s, because things are just not as good as they used to be is silly.
People aren’t that different. The opportunities to eat nice things, affordably, are different. Does that mean that we should look back to a rose tinted past where food wasn’t that nice, was possibly rationed and was expensive and wish that things were the same as they used to be? Fuck that!
