Irritated by my sister in law since she started Wegovy?

Since going on it she has become utterly smug!!

Every meal is a lecture about portions, willpower and how easy it is if you just decide to be disciplined. She brings it up constantly and watches everyone else eat with a tiny smile. She posts mirror selfies and captions about finally respecting her body. If anyone mentions side effects or cost she waves it away and says excuses are a mindset.

The thing is I am genuinely pleased she feels healthier. I really am. I just cannot cope with the sanctimony. Family dinners are exhausting and I dread comments about my plate. When I gently asked her to stop she said I should be inspired not threatened. I'm not overweight and have never struggled with my weight.

AIBU to think this is insufferable and want some boundaries or should I just swallow it and nod along? I really want to tell her this can't continue and she needs to calm down and stop with the horrid attitude.

You’ve tried the gentle approach. I’d speak to her much more forcefully if she keeps that shit up.

I think I'll have to. She was absolutely insufferable during Sunday lunch - I felt the eyes on me as I reached for a second serving of roasted potatoes!!

Really, she can exercise all that without the wegovy, and save some money, I take it. Either way, why is she focusing on your plate, if you have no weight problem?

GrumpyInsomniac · 11/01/2026 18:14

I’d be tempted to say that you’re glad the Wegovy has finally given her the chance to experience food the way you do naturally, and that it takes real courage to admit that you need help to control your appetite. You can’t imagine how hard it’s been for her until now, but good on her for getting help. And then smile sweetly.

And I say this as a card-carrying lard arse who would love to be able to afford the injections and wishes that she had an easy way to get her weight down to something sensible.

She focuses on everyone's eating! It's almost like since starting the injections she's hyper focused on food. Probably because she is not eating very much!

She’s going on about willpower whilst taking medication to suppress her appetite? Hmmm…

She’ll calm down (I hope!). Some people are like this when they give up anything. My mum used to say there’s no one as sanctimonious as a reformed smoker… (insert poison of choice here…)

canklesmctacotits · 11/01/2026 18:19

This is reason alone to refuse to be in her company when food is involved, until she’s calmed down. She can’t see beyond herself, and refuses to hear what you’re telling her. Why put yourself in the path of anyone who treats you like this? Use plain English and tell her you want a break from being obliged to listen to her talk about food and nutrition, that you find it ruins mealtimes for you and you want to enjoy your food. (Be prepared for her to accuse you of not being supportive of her weight loss journey 🙄)

TheMorgenmuffel · 11/01/2026 18:19

Tell her to shut up about willpower since she needed fat jabs to find some.

I'm on mounjaro and no willpower is required when you just dont feel like eating!

MovedlikeHarlowinMonteCarlo · 11/01/2026 18:20

This sounds very odd.

Why would someone on weight loss drugs be lecturing others?

Daleksatemyshed · 11/01/2026 18:20

Research now shows a lot of people lose weight this way but regain it once off the medications. You might like to point out the reason she became overweight was because she was so focussed on food and she still is, even if it's what other people are eating

Yes, it's a bit mind boggling. She talks about how some people on these medications can't control themselves and eat a whole box of biscuits or a family size Dairy Milk and are then nauseous. Which is true but also I thought the whole reason these drugs work is because you genuinely don't have an appetite. The people binging are not the norm.

I fucking hate people that talk about their weight and food and dieting all the time, it gives me a serious ick. It’s just boring and sanctimonious and it’s always the ones that struggle with their weight that go on and on about it. The people that actually have always eaten healthily with good portion control just get on with it. I’ve lost loads of weight and I never talk about it unless someone specifically asks, who cares? It’s not interesting at all is it? I’m also not stupid so I know I’ll look pretty foolish if I start banging on about it if I can’t maintain it. I would tell her a bit more firmly. My OH is on yet another health kick and I’m sick of hearing about it, I just told him earlier that I don’t want to know about the nutritional value of everything thanks.

mbosnz · 11/01/2026 18:23

I almost literally see flames when people comment on other people's food.

It is not respectful. It is not kind. It is not healthy.

Those are 'inside your head' thoughts. Perhaps she ought to invest in some masking tape - since she's not eating anyway, it won't matter if she has to tape her mouth shut.

Edited

Sadly the accusations have started. Not with me but with her parents. She was cross no one would go for a walk with her on Christmas Day! Apparently not wanting to go with her is not supporting her health journey.

See how she’s feeling when she’s been off it a month, I bet her willpower is somewhat waning at that point. I’m on Mounjaro and have been since Feb 25, I’m microdosing now to try to maintain my loss as I simply can’t do it alone! Once the meds wear off the hunger returns…..it’s simple and nothing at all to do with willpower!

Ecrire · 11/01/2026 18:25

Interesting to receive lectures on will power and mindset shifts from people who needed injections to turn off their blooming appetite. Hilarious doesn’t cover it 🤣

Samanabanana · 11/01/2026 18:25

If this was my sister in law I'd lose a stone naturally just to spite her but I'm pretty like that Grin

Popadomorbread · 11/01/2026 18:25

Just tell her you don’t have to be disciplined like her as you’ve never had a weight problem like she has. Thanks.

Saying this as a very fat person by the way. She’s a twat.

Summerhillsquare · 11/01/2026 18:25

Well, she had an eating disorder before and she has an eating disorder now, it's just adapted to the new context.

DecafSoyaLatteExtraShotPlease · 11/01/2026 18:26

I'd be calling her out on it at the next family meal. "Jenny, ive tried having a quiet word, but will you please stop. Your comments and judgement about other people's food choices are becoming insufferable and quite frankly, we're all sick of it"
Then help yourself to a second serving of dessert whilst everyone else gives you a standing ovation for saying what they've all been thinking

cheeseonsofa · 11/01/2026 18:27

She still has disordered eating.
Its the food equivalent of being a dry drunk

Firmly ignore her and if she mentions your eating habits tell her to stop
Failing that grey rock and LC

Merryoldgoat · 11/01/2026 18:28

Why are you being gentle?

’Julie - you sound so sanctimonious and I don’t need your commentary on my dinner’

or ‘Fuck off’

I say this as a Mounjaro user who has never commented once on anyone else’s food choices (except to admire what they are eating).

HoseGoblin · 11/01/2026 18:28

I think I'd faux-innocently ask her if it's all about discipline and willpower why does she need the jabs? Surely if she's so disciplined and respectful of her body she shouldn't need medical intervention to stop shoving food in her gob?

(I say this as a certified fatty who wears size Walmart and has zero interest in dieting, I just like annoying sanctimonious former fatties)

I agree. Complete obsession about food (whether under or over eating) is really not healthy.

I’d be going out of my way to stuff my face in front of her
