If you're using MJ, please advise me if you can.
In May I weighed 15 stone 7 pounds and I started using MJ 2.5mg.
I'm 5ft7, aged 50.
I have very gradually increased my doses and am now using 7.5mg.
I've used MJ every single week since May.
And all I've lost is 2 stone!
2 stone in 9 months!!!! Almost 10 months!
WTAF.
Whooooooo loses 2 measly stone in 9 (nearly 10) months?!?
Jesus wept.
Surely that's got to be the slowest weight loss ever.
I feel like crying.
I still have another 2 stone to lose before I even get near to the top end of a healthy BMI.
Am I to do this for another 9 or 10 months?!?
It's bankrupting me and destroying my self esteem all in one go😪

Are you eating less too?

Pepperama · 23/02/2025 23:08

Thats more than 1kg per month, which is in line with healthy weight loss. Some indications that slow and steady loss is more likely to keep off. Only way to speed up is probably to eat less - calorie counting or a higher dose. But not sure if that is desirable

unsync · 23/02/2025 23:08

What exactly are you doing? Can you share your meal and exercise plans. What's your TDEE and how many calories under are you? The answer will hopefully be somewhere in there.

Nevertrustacop · 23/02/2025 23:13

So you are losing weight at a perfectly healthy rate? Your options are eat less, up your dose or keep going as you are. There's nothing else people can say. I started in August and have lost just under two stone. Pretty much the same you. I've never managed that before so it's all good.

Theroadnottravelled · 23/02/2025 23:14

Watching with interest OP as I’ve just started MJ a week ago (2.5 dose atm) and I only lost one measly pound last week. I’m def eating less too. I hope it gets better. I’m on 1200 ish cals a day and have a coach.

Tittibits · 23/02/2025 23:28

Started mid July. Really slow weight loss. Sometimes no movement for 3 weeks despite going up the doses. Now have lost 3 st and 2 lbs. I learned that you have to be patient, although it’s not easy. I realised about 2months in how important protein is and so prioritise that daily. I don’t know if it’s possible to lose inches but not weight, because that’s how it seemed sometimes.

Like you I was despairing and considered stoping, but then I have lost 4 lbs in the last two weeks just doing the same as I have always done, despite losing no weight in the previous 4 weeks! Don’t be fooled by all the stories about lots of lbs dropping off in the blink of an eye. I’ll bet there are more people like you and I than those super losers.

One thing that helped me was a diary where it let out my frustration following slow loss along with my weight on that day- I was always so surprised to see that I had actually lost weight since my last entry, even though it didn’t feel like it.

OddSocksAreCool · 23/02/2025 23:32

Me! I've only lost 2 stone since June despite being in a constant deficit. Are you short? I'm only 4ft 11" so basically have to starve myself to lose weight. I'm on 12.5mg after losing nothing at all on 10mg and very little on 7.5mg. I think I should have stuck at 5mg and I don't know why I moved so quickly up!

richardosmanstrousers · 23/02/2025 23:35

What are you eating?

Icepop79 · 23/02/2025 23:41

I’m a very very slow loser. I started on Wegovy in January last year and switched to mounjaro in August. I had lost about 1.5 stone on Wegovy and have lost a further 2 stone on mounjaro. The things I keep holding onto are firstly, I am still losing even if it’s slow and secondly, I’ve never stuck to any weight loss plan this long.

I find that my most successful weeks are when I work with the medication. Sometimes I feel like I’m making the injections do all the work if that makes sense. When I step up and really focus on eating healthily the weight does shift a bit quicker.

Wonkypictureframe · 23/02/2025 23:51

Is there a reason you’re still on such a low dose if you don’t feel you’re losing enough? Agree with other posters that it’s fine to have slow and steady weight loss but you are at the bottom end of results and the advice would normally be to move up doses if you’re not happy with what you’re losing.

AelitaQueenofMars · 23/02/2025 23:55

OP, people post almost identical posts to yours over and over and over again, and the common theme is that none of them detail what posters are doing differently other than taking Mounjaro. And then they have to be asked, have you changed your diet, are you in a calorie deficit, have you increased your exercise, are you drinking lots of water, etc etc etc.
Weight loss isn’t simply about going on the pen, and nobody will respond in the same way!

Dazzlemered · 23/02/2025 23:57

This is exactly why I won’t pay for it. However after seeing it all over TT it has inspired me to try calorie counting and I’ve lost 16lbs so far.

PermanentTemporary · 23/02/2025 23:57

I'm quite a slow loser, and each dose seems to lose effectiveness over time. I've been on since I think September and am now on 12.5 which is definitely a more effective dose for me. I didnt feel much effect before 7.5.

I've lost 12kg so far which isn't far off half what I want to lose. The loss is noticeably quicker the more I exercise - does t ha e to be anything crazy but if I manage 10k steps a few days in a row the numbers always look good.

whatonearthisgoingonnow · 24/02/2025 00:00

2 stone in 9 months is plenty. You don't want to lose too fast and end up with saggy floppy skin, especially at 50.

Pyjamatimenow · 24/02/2025 00:03

I’d go up. I went all the way to 15mg and then came back down for maintenance

Wildywondrous · 24/02/2025 07:22

It seems to give different results for everyone, I'm the same height and age as you and have gone from 16st 11 to 11st 8 in 10 months which is 5st 3lbs (I've done two blocks of 5 months with a break of about 3 months in the middle).
I do eat considerably less than I was and pretty much healthy food apart from the occasional meal out.
I also do intermittent fasting which wasn't my original plan but with zero appetite I've naturally fallen into that routine.

I'm on the 7.5mg too which is working for me but I did find that on the lower doses that after a while I had no effects.

Is there a reason you're still on the 7.5 and haven't moved up?
Also would you have lost that two stone without MJ?

The drug alone won't make you lose weight, it's only an appetite suppression, I think of it as liquid willpower.

TriangleLight · 24/02/2025 07:27

Are you calorie counting? Work out you goals on the James smith academy free calculator, log religiously in my fitness pal: oil, salt, drinks, everything

Agix · 24/02/2025 07:41

All the weight loss injections do is decrease your appetite. Stop wasting money buying the injections and just eat like you were still on them.

ItShouldntHappenToMeYet · 24/02/2025 07:43

It isn't magic, for heaven's sake.
Are you also exercising and eating less?

rach7979 · 24/02/2025 07:55

Why have you stayed at the lower dose if you feel it's not working? Surely you would up your dose?

Zempy · 24/02/2025 08:03

Do you know there is a board for WLI? Lots of advice there.

How old are you? How many calories are you eating each day?

I have to be below 1200 to even consider losing, and most days on MJ I am consuming 800 - 1000. Lost one and a half stone since January.

@AelitaQueenofMars has nailed it!

You are wrong. Appetite suppression is a side effect and not the main mechanism.

They impact your hormones, increasing insulin response and slowing digestion to make you feel full for longer.

If Appetite suppression was all they did they wouldn't treat diabetes or PCOS.

That's not all they do at all, but if it was so easy just to eat as you would, people wouldn't be struggling with their weight in the first place.

Namsara · 24/02/2025 09:04

Why are you on 7.5 if you have been on it for 9 months?
You should be on 15 by now
2.5 month 1
5 Month 2
7.5 month 3
10 month 4
12.5 month 5
15 month 6

I'm on month 7 (second 15) and am down 2 stone. Yes I would like it to be .ore, but it's steady and it's off
