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.

Bettybuttinski, you can't control what others put in their mouths and I am sick to hell of you trying. I've had it. One more word and you are going to be eating alone. You're beyond rude.

Urggg my sister is on it and I snapped at her over Christmas dinner when she suggested I try it. I’ve just had my third baby and to be honest I’m actually doing much better than I expected but when she said it I really lost my temper. My dad diffused the situation and basically told her off (which I can’t lie felt kind of good, very childish I know).

Honestly if you’ve tried being nice sometimes it’s okay to just tell someone to shut up.

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).

This!

EmeraldShamrock000 · 11/01/2026 18:32

Have a chat, tell her it is annoying.
How often are you having a meal together?
Who is warning her of the side effects? If it is you, then stop doing that.
Her pharmacist or Doctor would have already advised her on the risk.
Let her have her moment, enjoying her new found confidence, I’ve never put on weight easy so I have never experienced being overweight. I’d imagine it is exciting for her. Have a word but let go of the aggravation, block or hide her SM posts.

MovedlikeHarlowinMonteCarlo · 11/01/2026 18:20

This sounds very odd.

Why would someone on weight loss drugs be lecturing others?

I think (for her) weight gain and weight loss are psychological. She was an emotional eater and I think she has some issues to work through. She isn't eating much but I think those things are still there. All the talk of discipline and willpower feels like things maybe she reflected on when she was heavier. It's odd but I can see why she is acting the way she is because she never addressed these issues.

You could go ‘full cunt’ and say ‘mate - I’m not the one using medication to eat normally - I don’t think you’re in a position to judge anyone’s eating’ and finish your pudding with relish.

HairyToity · 11/01/2026 18:33

I wouldn't say anything, it'll only backfire on you. Sometimes it's best to just smile and nod.

YourRealTurtle · 11/01/2026 18:35

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.

I think this is it. She got heavier for a lot of emotional reasons and I don't think she's addressed those so now it's coming out in a different way. All the talk of control and discipline and willpower is not really about the food.

I’ve been on WLI for 18 months. When I started I was in all the groups and it was literally all I could talk about at home; I think I was probably insufferable. I’m sure it’s replacing the food noise/obsession with something else. However, I was wise enough to know that the will power was only coming from the jabs!

That is a horrible thing to even suggest. I would bet money OP is thinking exactly on these lines. I think I’m one of the few slim people who isn’t jealous and rude about users of weight loss injections.
I think this thread is BS anyway.
Another made up WLI thread.
^OP shouldn’t be monitored she’s already disciplined blah blah blah^

That's interesting. It's only been three months for her so early days. Honestly I think she is just on a high because the weight is falling off with little effort from her. Not sure how she'll adapt when she goes off the drugs and the appetite comes back. I've heard that can be a really intense adjustment.

gamerchick · 11/01/2026 18:40

You've done the gentle approach. Tell her, nobody is interested and to stop looking at your plate. That it's turned her into an obsessive bore.

You might get a bit of peace for a few months.

Why? She’s being an idiot even after being asked to stop. It’s not hard to not comment on other people’s food.

I am on WLI and feel nothing about other people’s food choices and certainly not enough to comment and be sanctimonious about it.

Tbf if you know this, then why are you not being more understanding of why she is behaving the way that she is. It may be annoying you, but unless her underlying problems that you know that she has are dealt with, then how can she get past them? Has anyone suggested counselling. That would be kinder, and more useful. than eventually blowing up at her.

Loloblue · 11/01/2026 18:42

Sounds insufferable and also, when she comes off it let's see how the willpower is going? Utter horseshit.

Boom.
Not sure how she'll adapt when she goes off the drugs and the appetite comes back. I've heard
Showed your hand, like you really care about how she’ll adapt, just sprouting the nonsense that slim people use against WLI.
I wonder how you’d adapt if you even needed steroids or become immobile and very fat, from a fellow skinny, no jealousy here.

DinoLil · 11/01/2026 18:43

Perhaps point out if she hadn't eaten so much in the first place, followed her current new diet with some willpower then she wouldn't need to pay £££s for WLJ. (From someone who has lost 5st without WLJ)

You can have a chuckle when the weight goes back on!

Happyjoe · 11/01/2026 18:44

How bloomin irritating, dull and rude. If only she'd done all this before, she'd not need the jabs...

...and I think you'll have the 'last laugh' later on and can comment on second helpings of spuds... Going by the news this week, those who stop the jabs put on the weight 8 times faster than normal people who stop dieting.

OP would judge you for your lack of self control needing WLI to begin with.
I see through her false annoyance and concern.

Yeah I'm definitely not thinking any of this. I genuinely am happy for her weight loss however she does it.

You sound incredible judgemental - you are "one of the few slim people" who isn't rude and jealous? You are making assumptions about the other slim people who in your little world are seething with envy at people on weight loss drugs? Come off it, you sound like my SIL!

I mean this with kindness... But chemically suppressing your appetite is not willpower. Not even remotely..🤣 I'm not sure I'd be brave enough to say that to her mind!!

Her parents have talked about it. I think her GP also suggested it. We're not really close enough for me to talk to her about it, she would probably find it a bit intimate and odd. I might raise it with MIL again.

SquishySquashyWishyWashy · 11/01/2026 18:47

I'd put a hand on her shoulder and say calmly "listen, I am so glad that this is working for you. I really, really don't care at all about weight, and diet, and all that jazz, so let's talk about something else." On repeat every time she mentions it. Every time.

NotThisAgain1987 · 11/01/2026 18:47

LadyKenya · 11/01/2026 18:11

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?

Doesn't matter if she did have a weight problem leave other people's plates alone. It's rude and creates far more issues when meal times feel like your body is going to be torn apart.

OP I suggest you get a book called Say The Thing it's about inserting boundaries. Or go down the petty route and say wegovy makes you look like your skin is slipping off your bones and ages you terribly and ask if she's worried about the amount of people who shit themselves on it? That will probably shut down the convo sharpish
