I'm currently 107kg, I have been a few kg more.
Most of the answers so far seem to be from people who are unhappy or ashamed about their size. That's not me. I've always eaten well, home cooked, lots of veg, usually organic. Lots of butter. When we have a glut of home-grown fruit, we have a lot of fruit crumbles, with custard! And I do like chocolate!
I had an initial weight gain of a couple of stones, fast, when I had a difficult pregnancy with a lot of bed-rest, my baby was still born and I comfort ate afterwards.
And after that my weight just kept drifting up. I might be kidding myself, but I don't think I look as heavy as I am. I'm a size 20, which is still within the "normal" range at e.g. M&S, Next, Tu. There are styles I couldn't wear without sizing up, but I just don't wear those styles. If I can't get into it in a 20, I don't buy it.
I do worry that it will impact on my health at some point. I've made it into my 60s without any health issues (other than the recurrent miscarriages of my 20s and 30s, but I wasn't overweight back then.)
I'm not unfit. I can't run, but I swim (Tesco size 18 swimsuit), enjoy gardening, walk, bop around the kitchen to music.
I know I'm fat because I consume more calories than I use, but I also note that 3 of my 4 great grandmothers, all busy farmer's wives, were obese in their 60s (4th great grandmother died in childbirth, so no idea what she'd have looked like), as was one grandmother (also a farmer's wife) and my mother, now in her 90s, has never been slim either, although she's never been as fat as I am.
