my mum
does the same. baby voice of how she's always full and how little she eats. when we go out she never orders food and instead waits for our left overs and even if we're hungry we have to leave her some. it enrages me 🤣

what are leftovers? Never seen them in this house. I would delight in eating everything except eg fat off the steak edge.

"I realised that I have spent so many years being on a diet that the idea that you might actually need calories to survive has been completely wiped out of my consciousness. Have reached point where believe nutritional ideal is to eat nothing at all, and that the only reason people eat is because they are so greedy they cannot stop themselves from breaking out and ruining their diets." - Bridget Jones

Years ago I had a boyfriend whose mother was like the Final Boss of what's being described on here and he genuinely believed that the optimal human diet was zero fat, and that people just ate food with a fat content as some sort of tasty indulgence. When I said that it was recommended to be about 30% of your calories, he was entirely disbelieving.

Re Brigit Jones, that whole book is a historical document of the fucked-up diet culture of the time.

The people who made the Bridget Jones films didn’t understand the books.

The fat off the steak edge is my favourite part of steak. I would take great delight in eating this in front of a competitive under eater.

The time for this was before you felt moved to offer unasked for advice about further participation. I mean, talk about controlling.

Just as an observer of this bizarre tit for tat, it’s as boring as fuck and is completely derailing the thread. Two attention seekers with main character syndrome.

Thank fuck someone said it.

Me too, I relish the fat on a steak or chop etc. I used to fear it as a child because parents treated it like a kind of poison, and always told us off if we ate any fat on our meat.

It wasn't until I left home and started cooking for myself that I realised what I was missing.

GetOffTheCounter · 07/04/2026 19:29

Another one who loves the fat off steak. Also the fat off lamb chops. mmmm. DH before he became vegetarian used to shudder. So we were Jack Spratt and wife, not least because he is tall and thin and I am ... not.

I honestly don’t know why anyone (young/old, big eater/small eater) feels the need to talk about or worry about either their own plate, or what others are eating.🤷‍♀️

I can’t eat much, and I’m not shovelling too much food down myself, to keep others happy. Not interested in what they think. If I eat too much, I feel bloated and unwell. Not happening. 🙄

By the same token, I wouldn't dream of making snide remarks about others eating large meals, whatever their weight. Their business. .

Each to their own - but no need to talk about it to others. Do what makes you feel good. 🤷‍♀️

They are doing what makes them feel good by the performative under eating and the commenting on what people eat - that's why they do it!

These performative undereating threads always attract those "shrugging" posts from people who try to depict the undereater's hapless victims as "just as bad" because we "even notice" their exhibitionist habits.

The real problem of course is that it can be very difficult to draw the conversation away from a determined attention seeker, with the result that meal time too often becomes a stressful challenge.

Gosh... That's all shades of fucked up. Pretending you have an eating disorder is wild... I feel like your sister might be my mother. Everyone who has ever met her agrees she has a narcissistic personality disorder - even those that hate throwing around labels and diagnosing people based off cod-science social media listicles. Combined with crushing insecurity and wild over-sensitivity, and it is a lot to deal with.

My mum is losing weight at the moment through a GLP-1, but used to manage diabetes, not for weight loss per se. She has always been morbidly obese, for as long as I can remember, and HATED her appearance, so you'd think the weight loss would be welcome to her. She's doing well and I'd say she's about a size 20 now.

Except she is framing it as a medical emergency - the weight is just falling off her, she doesn't know what's wrong, she has no appetite, look at her, she's just becoming so THIN... Yes mum. It's because you are effectively on mounjaro. This is what happens. This is the side effect. She's being monitored closely by the GP for an inflammatory arthritis condition at the moment and has regular blood tests. There's nothing in her blood to suggest that she is dying of something that causes unexplained weight loss. The weight loss can, however, be explained by the diabetes meds.

And yet. She will not consider this as the explanation. Correlation does not equal causation - the fact that she started taking an appetite suppressing, insulin balancing drug at the same time as her appetite got suppressed is a wild coincidence. Will no one be concerned about her weight loss? How about if she mentions it all the time? Then will we give a shit?

The combination of endless humble bragging ("Guess what size this cardigan is? You won't guess. It's a SMALL. Try it on. I bet it won't fit you - but try it on!") and performative lack of appetite is exhausting.

I am taking mounjaro for weight loss and I am, objectively, much slimmer than her now, and it is driving her MAD. Especially as I haven't told her, just because I cannot be arsed with the conversation it will trigger. My sister knows, my dad knows - we're just keeping it among ourselves, because any conversations about weight and my mother have always been a fucking nightmare. She's still trying to palm off clothes of hers that don't fit any more, and she still makes me try them on in front of her in the hope that she can humiliate me by evidencing I'm bigger than her/make herself feel better by evidencing she's smaller than me. I can't work out what drives her - but she is always trying to get me to try her fucking clothes on.

My husband spends a lot of his time trying to change the subject when we are all together. Same with his mum, actually - she is obsessed with my weight loss. I explained to my husband how her constant questions and wanging on about it made me feel a few months ago and he was initially defensive - like, his mum's just being nice, it's compliments - but now he's seen how rabidly both his mum and mine go on about weight and link it to appearance/moral strength, he can see that their generation is fully fucked up and is a superhero trying to deflect both of them when they go off on one about my weight/their appetite/food in general.

They sound very similar . I do think my sister is a narc. Anything and everything for attention and always competing. If she thinks she's not getting enough attention she has 'collapses' but doesn't want to 'bother' anyone. She'll phone everyone but tell them not to say anything as she's a very private 🙄 person. Even though she makes sure she's got an audience but refuses to go to the hospital.

Agree, and fail to understand that, especially when it's a parent doing it, there is far more tied up in it - just tell them, ignore them etc. It's far more complex than that.

I suspect that both these contributor are, in fact, competitive under-eaters themselves and, as there is no visible food available, have to find a different way to compete each other into oblivion.

I was reading the book “Good Girls” by Hadley Freeman (about her time being treated for anorexia) and quite a lot of the stuff in the book seems quite similar to the stuff described here. There was one hospital, in particular, where there were quite a few older anorexics who would bully the younger ones. She was sitting her GCSEs and one said she didn’t understand how she could sit still for a two-hour exam because “I’d feel so fat”.

At one point, they would all have to sit at the lunch / dinner table but, because the older ones would performatively mess with their food, it would take up to two hours.

We don’t because we’re not all frail. I do have arthritis though. Hereditary. Silly mare yourself.

(a) The MIL's age hasn't been given, so I wonder how you know what generation we're talking about.
(b) It makes no sense to say that all women of a given age are all the same. Think about your own friends. Are they all the same? I doubt it. It certainly isn't true of everyone I know of my age. I've already said on the thread that there were no women who dieted obsessively in my family when I was growing up. There are none in my own generation either. I've been lucky there.

I for one take massive comfort in this thread, knowing that my struggles with my mother who is 100% like this are not unique. My sisters and I all agreed that the thing that would make our mother the most proud would be if we developed anorexia. Which is a truly warped thing to say, but her thinking indeed is truly warped. The constant comments on the nutritional profile of anything that hits our lips is just SO TIRESOME!

As a dare from one of my sisters I ate a full lunch immediately prior to a family lunch gathering recently and loudly declared that I couldn’t eat anything as I’d had two whole slices of toast for breakfast. My mother said nothing but I could tell she could not compute me - a normal person - willingly, casually skipping a meal when she is permanently tortured by hunger.

Its just so fucked up it really is.
