My mother cannot help commenting on women’s weight

My mother (60’s) recently moved into my neighbourhood and I’ve been forced to notice, again, how responsible she is for my own disordered eating and how awful it makes me feel when she can’t refrain from judging other women’s bodies! I introduced her to a close friend living nearby and after, my mother said ”she’s really big, isn’t she?”. She isn’t actually big, she’s completely normal sized!

It makes me crazy and I hate it - I’ve grown up with it, her judging everyone, herself and her 3 daughters. I’ve worked SO hard in countering all her comments regarding my younger sisters all my life. I’m a regular skinny weight now but she didn’t even notice how I had anorexia for like 15 years and was underweight. She comments on how everyone eats. We’ve lived in different parts of the county for 16 years so I haven’t really had to confront this in a long time, and I’ve no idea how to do it. If anyone has any advice I’ll happily take it. It’s just so completely unnecessary.
