I’ve been stuck between 88–89 kg for almost 4 months now, and honestly, it’s getting frustrating.
I was on 5 mg for the longest time (around 8 months) and managed to lose about 10 kg during that period. Eventually, the weight loss completely stalled, so I moved up to 7.5 mg.

It’s been 3 weeks on 7.5 mg now, and I’ve noticed something strange. The appetite suppression is pretty strong for the first 3 days after the injection, but by day 4, my hunger starts coming back, and by the end of the week, I feel like the medication is barely doing anything.
Despite increasing the dose, the scale just refuses to move below 88 kg. I’m honestly exhausted from seeing the same numbers every week.

Has anyone experienced a similar plateau that lasted this long? Did staying on 7.5 mg eventually help, or did you only start losing again after moving to 10 mg?
Also curious whether anyone noticed their appetite suppression wearing off around day 4.
Would really appreciate hearing your experiences, especially from people who’ve managed to break a stubborn plateau like this.

Hey, I am M22 188 cm, SW was 115 KG and my goal is 80-85KG I've only been on 1 pen of 2.5, and I'm now halfway through my first 5mg pen, 6 weeks total. My current weight is 102kg, and I feel great and have minimal side effects. However, I've been really anxious as it seems very fast to drop 13KG. I can usually only eat 1 main meal a day and lots of water, plus some fruit.

Does anyone have tips? Is this risky? Should I go back to 2.5mg?

thanks guys

I’ve been on MJ since August 2025, so 14 months, and have lost 19kgs so far…verrryyyy slowwlllyyyy! I was losing so much hair every time I washed it but since going up to 10mg it’s magically stopped! Anyone else had this happen?

Started 2.5 MJ on 25th Feb 2026 and had great success with few side effects. When i went up to 5mg the diarrhea and belly pain was too much over weeks so i went down to 3.3. I have been at 3.3 for months and still get diarrhea 48 hours after injection. Then i move to constipation by day 6 and 7, inject again and back to diarrhea. So far i have just accepted this and am happy to have lost 27kg on low doses. I am finding the foods I eat on particular days effect how severe the GI side effects are.

I mostly eat small meals and take de-gas and immodium most weeks to manage. I want to increase dose- last 2 weeks i have gone up slightly to 4mg and symptoms have worsened... usually only for one day and i have been home to manage however do i have to continue this every single week?

I havn't tried any other GLP1... anyone have advice please? Still have 20-25kg to loose.

I guess I just wanted to say a massive thank you to everyone here 🙏I have posted a couple of questions during my journey (that has only begun recently, so I’m sure there will be many more to come lol), and those questions have always been answered quickly and honestly and Ive never been made to feel stupid. I have found this group to be full of information and encouragement and I’m super grateful. My journey is going well starting at 93.5kg and was down to 88kg in 3 weeks which I was very happy about but in the last week my weight hasn’t really changed, it’s just been fluctuating between 88.3 and 88.9 and as patience has never been my strong point, I started to get a bit disheartened. But after some wise advice and encouragement from from you, I don’t feel alone, what I’m going through is normal and I feel much better. I understand that this isn’t a sprint, it’s a marathon and as long as I have appetite suppression it’s working and I just need to be patient and positive.
So again, thank you for the support and advice 💕💪🙂

I’m anxious to start this journey but I know it’s for the best.

My biggest worry is the cost. Would I be correct in thinking chemist warehouse is the cheapest place to purchase from? And are we all just paying out of pocket, since it’s not covered on the PBS?

Also, does anyone have advice for someone starting for the first time?

Thanks all! 😊

I'm on day two of 2.5 Mounjaro. I am feeling pretty full still from yesterday.

So far I've had a mini mandarin for breakfast and a tuna and lettuce sandwich cut into four squares and eaten a square every hour or so from 10.

I feel so full and bloated like I've eaten a full meal and I have to remind myself that I've not had that much.

I want to lose weight gradually and not too quickly so I'm trying to eat even though I'm not really hungry. Nutrition and getting enough iron is important to me.

Is this an okay routine so far? Drinking lots of water.

I finally took the plunge and started my Mounjaro journey. I started 4 1/2 weeks ago at 93.5kg on 2.5mg. Today I weigh 88.5kg. The first couple of weeks I seemed to be losing a couple of kg’s a week and was happy with the progress. But for the last couple of weeks I have stayed at around 88.5kg. Has this happened to anyone else. I’m going to speak to my doctor today but I was wondering if I need to go up. I haven’t had any side effects on 2.5 and it’s obviously more expensive to go up. I REALLY want to lose this weight, I’m so unhappy. I was exited when I finally saw the scale numbers decline after so many years of only seeing them increase, but now I feel a bit confused and defeated. Is it normal to plateau so early?

Hi everyone,

I am after some ideas on favourite recipes/put together meals/pre-packaged meals that you have eaten while on this Mounjaro journey. I love to cook so don't mind recipes from scratch but I also work long hours so looking for quick as well.

Would like some ideas for lunches or dinners especially. I don't have a huge appetite anymore (yay!) so trying to eat good food high in protein. Love all cuisines.

Just want some more ideas as trying to still have variety. Hopefully this helps others too.

Thanks so much.

Edited to add - I know there are other reddits I can search this on but wanted to keep it in a Australian forum as we will have access to meals/ingredients etc.

Hi there

I am on day 4 of my first dose and struggling to eat. It's suppressed my hunger and appetite and cravings more than I could imagine. However I make food and realised I must of used to scoff down my food. I am struggling to get calories in as I get immediately full.

Today I must myself a big protein smoothie so I can something but I dont know how to eat anymore

Please help

I have been on max dose 15mg for 18 months, and very slowly losing weight (SW 125kg, CW 93kg) and decided to start reducing the dose with the disappearance of the golden dose (motivated by cost). I decided to do 4 weeks at each dose. I did 4 x 12.5mg and felt some increase in appetite, weight no change (I am ok with that, good outcome considering scenario), but now I am on 10mg and 3 weeks in, and I am feeling the appetite suppression more than I can recall ever feeling it on 15mg. Has anyone else experienced this?

A minor win today. After my weekly weigh in my BMI is 29.4 so I am officially overweight and no longer obese. Still a long way to go, but it finally feels possible and sustainable.

I’ve been on the active pill continuously and take breaks a couple of times a year to manage PCOS and endo (which helps me a lot fortunately). But I’ve noticed since being on Mounjaro around 3.75 and 5mg that I’m getting breakthroughs for like a week or more, twice a month…

And it usually happens say after I have a bad eating day, get the runs, a couple of days later spotting then it’s like light-medium for a week or so.

I’m posting here to see if anyone else has had similar?

Wondering if I should just stop taking the pill and hope PCOS doesn’t come back as I ended up in emergency last time.

Hi everyone, I’m due to take my first 5mg Mounjaro dose today and wanted to ask for some experiences/advice.

Due to being away on holiday I’ve been drinking more alcohol than I normally would recently. Last week I drank on Friday, Saturday and Sunday, and this week I drank Monday, Tuesday and Wednesday (roughly a bottle of wine on the days I drank).

I feel completely normal and have no pain/side effects. I’ve decided to stop drinking from now on because I obviously want to take my health seriously.

I’m particularly worried about pancreatitis and have contacted my pharmacist to ask whether I should take my dose today or wait a couple of days after being alcohol free.

Has anyone else been in a similar situation? Did your doctor/pharmacist advise you to take your dose as scheduled or delay it?

I’m looking for experiences rather than medical advice , I’ll follow whatever my pharmacist recommends.
