WIBU to say this to my friend...?

[NewWednesdayNewName]

I have a friend who likes, at intervals, to say "you are so thin, I do worry about you..." and shake her head pityingly and in (clearly faux, imho) concern.
I've always been slim (BMI 19ish I think), eat well, never diet, and am healthy.
She is overweight and talks about it, and food, a lot.
It sort of makes me feel grim and intruded upon , and like there's something wrong with me, when she says this.
Would it be mean to reply with "I do worry about your cholesterol, as you're so fat"? to shut her up?

Yes, you would.
"I don't like it when you comment on my weight. It makes me feel bad about myself, and I find those comments intrusive. I think it's inappropriate to comment on other people's weight, I'd never do it to you. Please stop."

She should focus on her own weight issues rather than project them into you

You wouldn’t like it if I commented on your weight so please don’t comment on mine.
It makes me uncomfortable.

I have said very similar to your suggestions before. She just puts her concerned face in again and says "I just worry about you and would like to give you a proper meal"....

I think it would be a tiny bit mean, but I can totally understand the temptation of saying it.

I think TheShiteRunner has the right idea, but am not sure I could be so tactful.

If you have tried that, then perhaps it is time to be blunt. Depends how much you value her as a friend.

"You don't have a fucking clue what thin is." Sorry, that's me projecting.

I'd kill for DS 28 to put on a few hundred grams.

Thanks for getting it!

I probably won't be mean in reality, because I would really not want her to be upset and in most ways I like her very much and have been friends for 25 years. I expect I'm only venting. It just f*cks me right off as it's so frequent.

It never occurs to me to comment on anyone else's bodies (mostly because it's just not very interesting), except when giving a compliment.

@PhilomenaButterfly
I'm sorry - reading between lines - your DS isn't well(?)

He's got cystic fibrosis. He'll never be overweight. He's 5'10" and 48kg at the moment. He's in hospital right now, he usually puts on a bit there. 😊

People who say "You're so thin" really have no idea. I wouldn't be able to keep my mouth shut.

Shrug and say 'I just don't overeat' and then change the subject.
Or say yes I'm very lucky. I made a wish on a unicorn I captured when I was 12 never to be overweight.

Sounds like you may have to be more direct if you have tried other things.

"That sounds really rude and upsets me. I'd like you to stop saying that."

And repeat.

@PhilomenaButterfly, hope the weight's going on in hospital. And that he's out again soon. and to you both.

Thanks all for the ideas with friend

"We've had this conversation before. I don't want to have it again. Please do not comment on my weight or diet, because otherwise I will be sorely tempted to comment on yours. And believe me, DF, that is when the fight will start. . ."

Thanks @NewWednesdayNewName, we appreciate and ! 😂

Mbosnz aren't you delightful. OP, I would ask her if she's feeling OK, because she seems very preoccupied with size and weight at the moment?

Well, when I've tried polite, I go for direct. After all, they're being pretty bloody rude in the first place.

Just be rude and tell her to give it a rest already.

That must be so tempting. But please don’t make it about her weight. By all means call her rude/unkind/mean/bullying but don’t mention her weight, it will just make her go off on a rant about fat shaming and you will end up even more frustrated.
