I weighed just under 8 stone until I hit menopause. I blamed hormones while ignoring the large bar of chocolate in my hand
and the weight gain continued until I decided just before my 70th birthday to do something about it.
The only exercise I've done is 10k steps a day - even that was an effort to begin with, since I was a couple of stones overweight; I'm only 5ft 2, so the extra weight made a huge difference. One of my 70th presents was a Fitbit. I love it.
I didn't "go on a diet" - I counted calories until I sussed what I was actually putting into my mouth - but I did cut out cake, chocolate, biscuits, crisps and chips. Completely, to begin with. I'm not much of a drinker so that wasn't a problem. I drink water and tea and start the day with a real coffee.
I try to stick to 3 meals a day - plenty of protein and fat and not a lot of carbohydrates, because carbs seem to make my blood sugar levels wonky. If I have potatoes or rice, I have a small portion. Lots of veg and not much fruit - I like strawberries, raspberries, pears and plums in season but that's about it.
I lost 2 stones in 3 months and by summer I had gone down 2 dress sizes. I'd actually lost 2.5 stones by autumn and although I sometimes have chocolate or cake now, I find I'm not craving a lot. I'm just over 8 stone now and finding it easy to stay that size. I have butter on my toast and cream on my strawberries. If I eat out, I have small portions but I still eat pudding. If I feel I've eaten more than usual, I walk a bit more and eat a bit less the next day.
I honestly feel I have my life back. If an unfit oldie can do it, so can you, OP. Don't panic or get upset - just think about how much better you'll feel in a few months
