I’ve lost 9st, here’s my personal experience-
My family have been very supportive and have commented positively and encouragingly throughout.
The most support comes from overweight men. Men generally notice women’s bodies more than they admit. The overweight men are the ones who a) notice and b) empathise so they tend to be the most vocal and supportive.
Overweight women- depends on the relationship. Personally, I’d never comment on another woman’s body unless it was a very close friend and I was being complimentary and knew they’d welcome it. In the past, when someone has lost weight, I wouldn’t mention it because I’d be feeling down about my own weight and wouldn’t want to have the conversation.
Very slim women- I think for a lot of people whoever never had a weight problem, being a stone or ten stone overweight is still overweight in their eyes so they don’t really see the difference unless you become skinny.
As I said- this is my personal experience and obviously not a scientific study.
You’ve done terrifically well, OP. Don't forget, you’ve done this for YOU and nobody else. It’s your body that’s benefiting. I think when we’re overweight, it takes over so much headspace that other people just don’t give it.
Edited to add-
I’ve also had a couple of instances where people danced around the topic- as in, I could see they were looking at me and wanted to comment but didn’t. Then I’ve learned that they were shocked and wanted to comment but didn’t know if I was trying to lose weight or was ill. A few times, people have asked my family members if I’m ok health-wise, and have then complimented me directly when they know I’m ok.
