Gradually my life has got more sedentary.
I didn’t get a car until fairly recently. Before that I got public transport, or my bike.
My job is more and more computer based. I don’t need to move except to the toilet and break room. I can contact colleagues by skype, email. It wasn’t always like that- i’d be up and down the stairs to have a word with someone, getting up for a reference book, trip to the library, either in house or elsewhere for more research material.
Even standing behind a bar was more active.
Then when you’re young you spend free time walking round shops, walking round pubs, once a week dancing for a few hours. Going to friends houses, just generally moving.
Post children i drive to work, sit. Drive to pick up kids, sit and watch whatever activity. Home, cook tea. Collapse exhausted. Rinse and repeat. Food and shopping delivered as I don’t want to be dragging children shopping.
My step count must have decreased over the years from 15-20 000 a day to less than 3. I went on a walking holiday last year, 15k steps a day, ate out every evening, and came back half a stone lighter after 2 weeks.
i reckon it’s just general lack movement in my life compared to when I wasn’t fat. I definitely eat less (and better) now than I did then...
