My personal opinion is it’s not so much about food, although supermarkets and ready availability etc haven’t helped, but NEAT (non exercise activity thermogenesis).
I am old and was actually alive 50 years ago. Shopping habits were different, we didn’t have massive freezers so my mum would walk to the butcher/baker/grocer several times a week. No 24 hour tv or computer games, we played out from young ages.
even little things like homework. No information from our sofa, it was a trip to the library to look it up.
when I started my first job I was office based, but still in my feet most of the day with short spells at the computer to make notes, write things up etc. if I wanted something I got up and got it. Now, same job but I don’t need to move. Speak to a colleague? Teams. Need a research article? On line. Even lunch is now 20 steps away to a microwave because many offices are now on industrial estates so you can’t pop out, and no canteens even to climb a few sets of stairs.
women put menopausal weight gain down to hormones but when I look at my activity now vs even 10 years ago when I was walking kids to school, walking to the bus stop, taking kids to the park and generally out and about, I am simply less active.
i reckon my step count and general activity levels were way, way higher in the 80’s and early 90’s.
so yes, imo it’s the advent of computers and everything at our fingers, instead of getting up to get something. How many of us here would have got up to go meet someone for social interaction vs mumsnet?
as for o/p yes I am in a similar loophole. Got myself from obese to just very overweight, but an struggling for the last few stone to get healthy but am no longer overweight enough for wld. That’s if I could afford it!
