7 stone down on mounjaro - but not seeing a change in dress size

stclementine · 17/06/2025 20:33

Just that really. I’ve been taking mounjaro for just over a year and gone from 17.5 stone to 9.13 as of this morning, yet I’ve only gone down from a 24/26 dress size to a 20/22. It’s making me doubt myself, my scales, everything. People are noticing that I’ve lost weight and some of my old clothes are nit ridiculously baggy, but I thought I’d be smaller by now? I’m short - barely 5’2” and middle aged so have that spread (but not menopausal or even peri menopausal). Is it me, or have other people had a similar experience? I’ve got 3 stone to go until I’m in the middle of normal BMI.

No way should you be 6 stone as an adult woman
We are different when we are older I weighed less after losing 2 stone than I did at my wedding but my boobs made sure I was in a bigger dress size. No matter what I lose my boobs get a bigger cup size
Have you seen a personal shopper you may need to change the cut of your clothes.

Because they’re responding to you accusing us of nefarious reasons for pointing out that it’s not in the middle of the healthy weight range 🤷🏻‍♀️. Thats why I keep replying anyway.

I merely pointed out that it was in the healthy range. It was only when posters went wanging on & on about the “middle” that I inferred there must be something behind it.

As it happens @Shmee1988 rather proved the point.

Well yes, you definitely proved that @Shmee1988 , one single poster, held the view that you were accusing multiple posters of having, so well done for that 👏 .
I knew it was within the healthy range so didn’t really need that pointing out. I also knew that it wasn’t in the middle of the healthy range, which is what the OP actually said, so was just trying to clarify if the OP had her numbers right.

ImAboutToFold · 19/06/2025 16:56

Regardless of anyone's weight @Mirabai the first post by the OP is a bit worrying - I am aware she later corrected the amount she has to lose. But when you read it at face value, she's saying she wants to go below 7 stone, she's saying that a weight near to the bottom of her healthy range is in the middle of it and she thinks she's still a much larger dress size than she can possibly be. It rings a lot of alarm bells for someone who might be in the grip of dysmorphic or disordered thinking.

I'm aware that she has now said she doesn't have three stone left to lose, so isn't aiming to go below seven stone. But I can see why people would absolutely challenge the details in that first post as what the OP says doesn't align with reality. There is a difference between aiming for the middle of healthy and aiming for just above underweight. It might be a totally appropriate goal, but when it's coming from someone who thinks they're still a size 22 at 9 stone something, posters will question if there is something worrying going on.

MyJoyousKoala · 19/06/2025 16:56

I’m the exact same height and weight as you and have lost 4 stone on Mounjaro and I am now a size 12. Is it possible you’ve lost sense of your actual size and are wearing clothes that are much too big because that’s what you’re familiar with?

TerroristToddler · 19/06/2025 16:59

Surely not!!? I'm 5ft 2 and weighed 10stone exactly in Jan.... and was a size 12 on bottom, 10 on top. Now 9st 7 and a size 10 in both.

I get you might have lose skin and stuff given you've lost so much weight (well done btw - that's a bloody amazing achievement) but you are def not a size 22!!!

Do you think your brain is struggling to keep up with your body, and somehow still thinks of itself as a size 22?

NotTheRealStacy · 19/06/2025 17:14

OP, treat yourself to some new clothes, you can not possibly be still fitting into a size 22.

Yeah that’s the only bit that’s worrying in OP’s post. Not the fact she’s taking Mounjaro, which can have serious side effects, or the fact she was ever 17.5 stone at her height.

She’s obviously not that familiar with the lower end of the BMI calculator so she’s a bit hazy about where she needs to get to, but she will find out soon enough.

Can’t we just be supportive of the fact she’s lost a colossal amount of weight and wish her well on her journey?

NHSinterviewupcoming · 19/06/2025 17:35

ive lost seven stone, down to 15st9. I thought I was the same clothes size till I started trying on new clothes. Down from a size 28 to 16/18.

whatsit84 · 19/06/2025 17:39

Wouldn’t you be about a size 12, 14 at a push?

InWithThePlums · 19/06/2025 17:58

Mirabai · 19/06/2025 00:01

She’s 5’2 how big can her frame be. I didn’t say it was in the middle of the healthy BMI and there’s no rule that says you must be.

🙄

There’s no rule that says you have to be in the middle. I’m just saying 7 stone 7 is pretty light for 5’2, albeit just about in the healthy category. Substitute “small frame” for “narrow frame” if it makes more sense to you.

Yep, this.

At the end of the day, words mean things. OP clearly stated 7.5 stone is middle of the normal range, when it’s not. I’m not just going to ignore the word “middle” when she deliberately inserted it. It makes a key difference to what she is saying.

As I said I’d also correct them if they claimed 9stone 8 was “middle” too, when it’s not.

I didn’t actually tell her to not aim for 7.5 stone or to do so - that’s another discussion.
All I said in the post that was quoted is 7.5 stone is not the middle of the normal range for our height, which is absolutely correct.

Juic · 19/06/2025 18:12

Mirabai · 19/06/2025 15:17

Fact is that 7 and a half stone is in the healthy range for OP’s height. That’s all there is to it.

I didn’t ever say it wasn’t in the normal range. I even later quoted something from nhs website showing that it is within the range - way towards the lower end.

It’s helpful to those on a weight journey, not just OP but anyone reading, to know the facts.

If someone does get to the lower range thinking it’s the middle it can actually be very dangerous - they may think they can lose another half stone for example, when in reality that’s going to push them into the underweight zone since they’re already close to the borderline. If an adult reaches 7.5 stone and thinks they can/should drop below 7 stone yeah it’s a problem!

Anyway as above, words matter and the Op specifically said it’s the middle of the normal range when it’s not.

She was wrong. I was correcting that. That’s all.

Indeed. They are the one who keep going on about this and challenging various posters about it when all many of us did was state facts.

Juic · 19/06/2025 18:24

Crikeyalmighty · 19/06/2025 16:15

You can’t be correct OP - I’m 13 stone 9 at moment and an 18 in some things, 16 in others that have a bit of stretch - and I’m 5 ft 4

Exactly. I’m the same height and 10 stone 7 and wear 10-12. When I was almost 13 stone I wore around size 16 I think. Now when I wear my old size 14 or 16 (can’t remember which) jeans around the house they are literally falling down my butt. Hence i only wear them indoors with no guests around! So I don’t see how OP could weigh less than me at the same height and be wearing size 20/22. I was wearing size 8-10 at just a few pounds lighter than her current size.

I get body composition and the fact we are all shaped differently and weight doesn’t show up the same on everyone but this doesn’t add up

I’ve suggested upthread OP might like to weigh herself on a different set of scales. The only other thing I can think off is if she is wearing clothes that are literally falling off her and relying heavily on belts and wrapping material around her to keep things on.

AmythestBangle · 19/06/2025 18:35

I'm 5 foot 3 and 8 stone 8 now. I've lost 2 and a half stone and have got to BMI 21.5. I have gone from size 16 to size 10-12 depending on brand. You cannot be a 22, it's not possible.

AmythestBangle · 19/06/2025 18:36

PS don't aim for a BMI of 19 unless you are a teenager, it is too low and won't look good either.

RealMintBird · 19/06/2025 18:40

Mirabai · 17/06/2025 21:25

I’m sure if you tried clothes on you’d find you fit into smaller sizes.

7 st 7 lbs is a reasonable goal for 5’ 2. I’m 5’4 and 7 stone 12.

it's really not a reasonable goal unless you are of certain ethnicities or much younger in age....if she (or you) is an older person ,going into older age at a lower weight is associated with worse health outcomes than being overweight. Those people with body dysmorphia who have been obese and have lost a huge amount of weight are at risk of tipping into malnutrition as their weight loss progresses as they have lost touch with a healthy view of their body.

And this is what I mean by loss of touch with reality. I’m 54. 5’4, 7 stone 12 I look perfectly healthy. I’ve been around this weight all my life.

When 60% of the population is overweight or obese - people have lost touch with healthy weight.

And that, no matter how posters try to spin it, is what 7’7 is. It in the healthy range for 5’2. A healthy weight/BMI is optimal.

The reality is after a major diet OP will likely hit target weight at the end but then normalise over time a bit higher. She’s not there yet and she might never get there so it’s all moot.

FFS I didn’t try to ‘spin’ anything. The OP
said ‘7 stone 7lbs is in the middle of the healthy weight range for my height’. I said ‘no it’s not, it’s towards the lower end of the healthy weight range for your height’. Do you usually have difficulty distinguishing ‘fact’ from ‘spin’? You are the one who appears to have an agenda here.
The OP appears to have some level of body dysmorphia. She thinks she’s still a size 22 at her weight. Encouraging someone with dysmorphia to aim for a weight at the lower end of the healthy range is irresponsible, whatever the fuck you personally weigh. It’s not about you.

Shmee1988 · 19/06/2025 20:12

Mirabai · 19/06/2025 15:22

This is exactly the type of perspective I was referring to.

The idea that someone of 5’2 would look “gaunt” or “unhealthy” at 7 stone 7 is entirely fantastical and purely an assumption on your part. It’s absolutely in the healthy range.

Our supersized society has lost sight of normal.

A 12 year old at 5ft2 would look fine at that weight. A grown woman, would not, in my opinion. Bmi is a load of rubbish.

AmythestBangle · 20/06/2025 00:36

Your optimal bmi for health/longevity changes as you get older. At 60 you don't aim for 18 or even 20. I am nearly 62 and BMI is 22, which was my goal when I started WLI I am not going any lower (and my provider has put me on maintenance anyway).

AmythestBangle · 20/06/2025 00:38

And I am now size 12 ( can fit 10 for sure but prefer rather looser fit). No way you are a 22.

@Mirabai you have missed the obvious point that you have been that weight your whole life whereas this poster is on WLI due to severe obesity with all the disordered eating that that entails. WLI prescribers do not continue to prescribe down to the lowest possible BMI, they often cut off around mid-BMI range with good reason and then the person has the option of a maintenance plan ,depending on their circumstances, or by going it alone via traditional methods. Losing a huge amount of weight doesn't automatically come with a reset of disordered eating. if you choose to look at https://www.smartbmicalculator.com ,which is more approriate for someone our age ,i took the liberty of inputting your stats, here what it says "
"Your body mass index (BMI) is calculated as exactly 18.9 kilograms per square meter.
Health aspects
Your weight is at a marginally lower level; in our view, it still should still be fine for your health. By classification of the WHO, you are "normalweight".
Your low body mass will not be a problem for your health provided you are getting sufficient amounts of vital substances such as protein, minerals, vitamins and essential fats. A low but stable weight may be fine, but an unintended weight loss could be a sign of poor health.
SBMI = 29/70
This assessment is based on the newly developed Smart Body Mass Index. Its ideal range is between 30/70 and 39/70.
Your Smart Body Mass Index (SBMI) is calculated as 29/70 or "29 points out of 70".
Weight stability
Do not lose any weight. A small gain in weight could be beneficial, preferably by building up muscle mass.
Weight management
With a weight gain of 6 pounds up to a target weight of 8 stones 4 pounds, your health would benefit."
as i said, going into older age, lower weights for women are associated with poorer health outcomes "https://www.verywellhealth.com/healthy-weight-and-bmi-range-for-older-adults-2223592". someone on long term WLI or trying to maintain a very low BMI via calorie control may struggle to eat a nutritionally adequate diet, hence why aiming for the lowest BMI possible is not always healthy,depending on your age/ethnicity and personal circumstances. Aiming for a stable healthy weight is best.

Calculate your BMI, correctly rated according to age and gender

Along with your age, the rating of your body mass index is markedly changing. For a detailed overview, use your coloured health risk chart.

It's absolutely impossible that you haven't gone down in size. However, our brains can be strange at times and it's quite possible that there is a disconnect between what you see when you look at yourself and your actual size.
I started at 17stone and I've lost 4 stone. I've gone from a tight 18 to an easy 14 and could probably squeeze in a 12.
But, I do have a few dresses which are an 18 which I can put on and still appear to fit me. They are too loose and probably look ridiculous but I still look at myself in them and think, how do these still fit? It is also quite possible, that I was squeezed into them before and was really a size 20 (in fact, I'm fairly sure that's the case).
Also, I have a pair of cropped trousers which I love. They're an 18 on the label but honestly, they are not!! I couldn't have got 1 leg in before when I was an actual size 18.
