AIBU to feel uncomfortable about my MIL's behaviour around food?

Sorry, this ended up being quite a long post.

I don’t know what advice I am looking for and simply wanted to share this with other people to see if anybody else has ever experienced anything like this?

MIL, who is past retirement age, has a not so healthy relationship with weight and food. There are reasons I say this which I won’t go into, but let’s just say it is off topic for this thread.

I put on weight recently, but my BMI is in the green, right in the middle. This comes after years of being underweight, at times dangerously so, and struggling to put weight on, for reasons that are also off topic here.

MIL is now constantly asking me how the weight loss is going, measuring me up with her eyes, essentially fat-checking me… she does try to be discrete about this but I’ve seen it happen. She will ask whether I have managed to lose any weight since the last time she saw me. She then confirms “but the weight is going down right?”

She herself is not underweight for her age but is on the thin side.

In her fridge and cupboard, she keeps lots of out of date, expired food. Often mouldy. She will tell anybody who listens how she doesn’t gain weight and how proud she is of it, then going into details about how she manages to do that. For example, if she has eaten a lot one day she will try to not to eat very much for several days thereafter.

Unless she eats out, she’d does not eat “real” food, instead snacking on things like tomatoes or biscuits or nuts, or if she decides to have a meal, it will be something like canned soup. My understanding is she doesn’t really know how to cook, but that isn’t something you can judge her for because not everybody does.

She will often go out of her way to make sure her son (my husband) gets food when we are there, but will essentially do the opposite with me. This used to happen even when I was very thin. If we would go out for a meal she would order something “healthy” then try to eat my food and actually verbalise that she won’t take any from her son’s plate because he needs it. She would encourage her son to get the most expensive and substantial option on a menu, and although it has never explicitly been said I always feel that I am supposed to pick something cheap, sometimes based on suggestions she makes but mostly it’s based on experience from eating out with her and the sort of obvious conclusion you can draw from the behaviour when I do get something that isn’t the very cheapest option (she tries to eat my food). Of course it is possible this is all in my head but I am fairly sure it is not.

I feel like there’s an aspect to this which comes from a need to hoard food because food costs money. Or making sure you get your money’s worth (since she paid for the meal). So her son eating is getting your moneys worth, me eating is not. This behaviour extends to other situations but again it’s a bit off topic.

She does offer me what is in her cupboard and fridge but as I say it’s all expired and mouldy. In the same breath she will talk about how to ensure you don’t get hungry by snacking on small amounts of food like sweets and nuts.

On our most recent visit she made her son some food (tinned soup). She did not offer me the same. She then told me to join her while she ran some errands, in what felt like an attempt to distract me from eating. At this point it was late afternoon and I had not had anything to eat all day. She later offered me tomatoes and crackers.

I don’t think I will ever try to “set a boundary” because to some degree it is a lost cause and I don’t want to make her cross, I mostly try to eat before and after seeing her, but sometimes there isn’t time to do that.

What does your husband do when she starts this nonsense? My partner has an aunt like this. He tells her to pack it in, and if she doesn’t then he takes half the food from his plate and gives it to me. So… what is your husband doing?

SnappyQuoter · 19/05/2026 13:10

Duplicate post.

Cherrysoup · 19/05/2026 13:12

Do you let her take your food? I would go nuts! Have you had a conversation with her?

The only reason this woman is in her life is because she married her husband. So he should be dealing with it. If it’s anything like most mumsnet marriages then the OP is probably carrying most of the mental load and doing most of the day to day drudgery in her own home. She should be taking on her responsibility of dealing with her nutjob MiL as well.

Lottapianos · 19/05/2026 13:14

Gosh OP, this is pretty dark stuff. She sounds absolutely obsessed with food - monitoring and controlling and trying to eat as little as possible - and it's extending beyond herself to include you as well.

Please do not accept the very messed up role that she is assigning to you. You are an adult - you need to order and eat what you want to. I wouldn't allow her to eat any food off your plate either. Her boundaries around food are massively blurred - push back, and don't join in with the unhealthy behaviour. I notice you are already questioning whether this is all in your head - it's a very strange experience being around this level of eating disorder. You need to protect yourself and not get sucked in to her version of reality

Nothing really… He eats his food. Sometimes chuffed, if it’s at a restaurant, or something he likes. Sometimes in despair because it’s awful/gone off.

If it’s about the weight he just doesn’t say much, she does the same to him. Other times we both just appease her by essentially agreeing she’s very clever to have come up with such fabulous weight loss tricks…

I think you need to stop the appeasing, and move the conversation on to something else. I know this is not easy, and I'm sure there is a lot more to the dynamic with your MIL than just the food issues

AnnaMagnani · 19/05/2026 13:18

She may well have a life long eating disorder which she has just about kept underwraps by not being too thin and using socially acceptable behaviour such saving money and men eating bigger portions.

Only these behaviours aren't as acceptable now and they are driving you up the wall.

OP order what you like and tell her that you know she cares but nowadays it's rude to talk about weight.

thepariscrimefiles · 19/05/2026 13:22

If I were you, I'd stop visiting your MIL. She is obviously obsessed with her weight to a completely unhealthy extent and she is trying to include you in this weird competitive under-eating dynamic.

She is really rude to provide your DH with a proper meal without doing the same for you. Let your DH visit her but you should stay at home.

Wow. You picked the wrong man then, with the wrong mum.

titchy · 19/05/2026 13:22

Do you stay with her? Why did you go all day without food? If you know what she’s like surely you take your own food? And order what the hell you want from a menu. Obvs pay for it, don’t expect her to. She is welcome to her issues but you don’t have to go along with them, so why do you?

Backedoffhackedoff · 19/05/2026 13:23

She’s got an eating disorder and it’s not uncommon at her age at all.

i wouldn’t do anything- ignore her quips, take your down snacks, tell her to leave your food alone. But all the while remember neither you nor your husband will solve this, and she can’t help it. Realistically she’s not to recover at her age

titchy · 19/05/2026 13:23

And yeah your dh is pretty shit, doesn’t defend you and eats mouldy food rather than offend his batshit mother.

mindutopia · 19/05/2026 13:25

Well, first of all, Dh would always make sure I got the same portion as him and that I always had enough to eat.

Personally, I would not have meals with her at all if this was how she was going to behave. No restaurant meals ever. We visit for a cup of tea only and bring biscuits and cake to share (which she could not eat if she didn’t want to). Dh definitely wouldn’t eat sad gone off soup while I sat there having nothing. We’d cut the visit short and go get some food.

This is bonkers enabling behaviour all around. Stop pandering to this nonsense.

DrinkFeckArseBrick · 19/05/2026 13:28

So what actually happens, when you go to hers and she makes him food and not you? I can't actually imagine this situation...does he just say thanks and eat his soup while you just sit there with nothing?

The whole thing is a bit batshit. What do you actually want to happen? Her behaviour is unlikely to completely change (she will likely always be weird around food). Do you want to avoid eating around her? Do you want her to stop trying to eat your food when you're out? Absolutely no way would I be wanting to discuss my weight, or eat a tomato and crackers for lunch. I'd also not be wanting to accept her paying for a meal out if she thinks she has control over what I eat. But what boundaries do you want to put in place?

alexdgr8 · 19/05/2026 13:28

Just be more straightforward.
Don't shilly shally around as if you are in the wrong.
You don't have to make any comment about her or her habits.
Simply be yourself and state your needs.
So if out with her say
I need to eat now.
? Is this cafe OK for you or do you prefer the one across the road.
A bit like with toddlers dressing. ?green shirt or blue.

If going to her house bring food with you or order a takeaway to be delivered.
? Indian or Chinese mother ?
Any comments about your weight just say
I'm not trying to lose weight. ?how are the begonias.
All the best.

BaublesAndGlitter · 19/05/2026 13:31

Take snacks or a packed lunch with you when you visit her and just eat it whenever you’re hungry.
If you’re out for a meal, order what you want even if you make a point of paying for it (tbh I don’t think I’d let her buy me a meal with the way she approaches it). And don’t bloody share a bite.

Have some stock responses when she asks about your weight - try ‘I’m focusing on health not weight’ and ‘I’m not monitoring, I think I’m in pretty good shape’

Also, you need to get your DH on board. Her issues may be deep seated but she’s treating you really badly and he’s letting her. He needs to point out that she hasn’t given you any dinner or that she’s trying to take your meal.

Also, you don’t mention any children but if there are any in the family, be very aware of the impact her issues could have on them.

SummerInSun · 19/05/2026 13:32

I really hope you don’t have any DC who are being exposed to what is at least disordered eating and may be an actual eating disorder. If you do, you need an absolute red line against her talking about food or weight in front of them.

It doesn’t sound like you will be able to change your MIL as I suspect her problems with food are so deeply ingrained that would take her acknowledging she had a problem and seeking professional help to sort it.

If it were me, I wouldn’t get into a row about it, but I just wouldn’t pander to it either. If you are in a restaurant, order what you want. If you are staying with her, go to the shops and buy what you want and just say “I don’t want you to have to go to the trouble of cooking for me so I’ll sort myself out.” If she tries to talk about your weight just say “I’m a healthy weight and happy with it”.

All of this!

GreenCandleWax · 19/05/2026 13:33

I voted YABU but that is because you have failed to set a boundary between yourself and her crazy and unhealthy behaviour towards you. Be assertive. If she tries to talk about you and food, tell her you don't want to discuss it. Repeat each time. If she tries to take food from your plate, absolutely do not allow it. You could sit as far away as possible from her at a table if that helps. Be firm - it is completely unacceptable to take your food, or comment on your body. As for you having to order cheap dishes in a restaurant - do the opposite, and have something expensive that you'd really like.
Firm upn your resolution not to be treated like this.

So your DH gets offered food and you don’t, and he just eats the food… he doesn’t say “aren’t you going to offer DW food too mum?”?

That is really strange. You’re both participating in her batshittery and therefore making it seem normal. It’s not normal.

If she comments on your weight just say “I’m happy with my weight thanks”, give a vague ‘hmm’ or just pretend you haven’t heard and don’t say anything at all.

Presumably you have discussed it with your DH.. what does he think about it?

TheSandgroper · 19/05/2026 13:42

Take food to eat. Order what you want at a restaurant. Tell DH to stand up for you.

Wonder about how she was brought up by her parents (who would have been Depression/war children). Generational trauma is a thing and can manifest itself in funny ways.

DeftGoldHedgehog · 19/05/2026 13:43

I would just tell get to stop going on about your weight, you are a healthy weight and it's none of her business, and see her as little as possible. If DH wants to see his mum he can go round on his own.
