Scared of hitting a weight-loss limit

Hi all;

I've been on MJ since the beginning of February 2026. I started Mounjaro at 245 lbs (technically, a month before that I was at 251 lbs, but I think some was Christmas weight). I'm on 7.5 mg now at down to 209 lbs.

I'm sticking around 300 calories below my TDEE. I'm still seeing average weight loss about 2 lbs a week. I walk daily and am about to start a weightlifting regime to regain lost muscle. Things are going well. It's been a life-changer -- I have more energy, I think more clearly. I told my wife I feel about 10-15 years younger.

That said, I'm a bit nervous. I've been told MJ will usually cause me to lose about 20% of my original body weight -- which would mean about 50 pounds, which I'm getting closer to. That still keeps my BMI in the obese category (I'm 5'5'').

I realize everyone's different -- but I'm curious about whether anyone has lost more than the 20% range. I'm not in a hurry. I'm 47 and would love to be down to between 150-160 lbs by the time I hit 50. Any recommendations from those who have lose weight?

Weight gain after 3.5 months on Mounjaro - seeking advice

Hi everyone! I’m currently 3.5 months into my Mounjaro journey and I’m feeling a bit discouraged, so I wanted to reach out for some perspective.

For context: I’m 160cm (5’3”), and I have hypothyroidism and Hashimoto’s (AIT).

So far, I’ve lost a total of 8kg, which I know is progress, but I’ve hit a really frustrating plateau.

My weight hit a low of 67kg on June 5th, but since then, the scale has been trending upwards. A couple of days ago I was at 68.8kg. To be honest, I gained about 1kg just over the last month, even before my recent vacation.

I just came back from a week-long vacation where I definitely indulged in some beer and cocktails—I’m sure I hit my maintenance calories or maybe even went over—but the upward trend actually started about 4 weeks ago, not just this past week.

I still have a long way to go to reach my goal weight, and I’m feeling pretty stuck. Did you find that you needed to increase your dosage to break the plateau, or is this just a normal part of the process?

Any tips or experiences you could share would be greatly appreciated. Thanks in advance!

First refill pen use: storage, injection temp & priming question

Hi all,

I took my first 2.5 mg dose last week and I’m scheduled for my second injection in a few days.

My endocrinologist prescribed me 10 mg pens so I can stretch them a bit in this early phase for cost reasons. Since the pen will last more than a month, I’m storing it in the fridge.

A couple of questions:

  1. Before injecting, do you usually let the pen reach room temperature, or do you inject it straight from the fridge? Any practical difference in terms of comfort or effectiveness?

  2. After attaching the micro-needle, I sometimes don’t get a drop to appear on the first try. The leaflet suggests doing a couple of priming clicks until a drop shows up. If I end up doing this extra priming before each injection, does it affect the actual delivered dose in any way, or is it already accounted for by the pen system?

Thanks in advance for any practical tips.

One year of starting mj and locking in

I started my mj and fitness journey a year ago, exactly a week after I finished breastfeeding my second (& last) baby.

I spent the first couple of months just dropping weight, then added weight lifting (dumbells at home with progressive overload) which I've been doing for the last 10 months.

I had my last dose of mj 3 months ago and am now in maintenance (too expensive for me long term). I am posting monthly maintainance updates but thought I would post my one year out update as well. This is the first time in my life I've ever seen my abs which is pretty exciting for me.

I have a fair amount of loose skin (as you can see around my sports bra) but it doesn't bother me too much excpet my stomach and breasts which I am hoping to save for surgery to improve.

I LOVE feeling fit and strong, not worrying about being too tired to enjoy anything, and feeling like I could take care of myself and my kids if I need to.

Best of luck to everyone on your journeys. I really recommend weight training, I was a complete novice to it but with a set of adjustable dumbbells I've built a full body routine I can stick to every week. Happy to answer any Qs!

8 months on Mounjaro: 348 → 267 (81 lbs down). Type 2 diabetic, 9.1 A1C, hypertensive, food-addicted.

Post body:

November 1, 2025 was my start date. Here's where I was standing:

348 lbs

  • Hypertensive
  • Food-addicted, and I don't use that term lightly. Food occupied my thoughts
  • constantly to the point I was planning the next meal while eating the current one, the whole exhausting loop.

Eight months later I'm at 267, down 81 pounds. Currently on 7.5 mg. I've been holding at that dose for 4 months (3 months 5mg, 1 month 2.5mg) and don't plan to go up as long as progress continues. Started out losing about 4 lbs a week, and now I'm at a steady 2 lbs weekly, sometimes a bit more. Slow and steady is fine by me.

First, the luck part, because I want to be honest about it.

I know not everyone responds to Mounjaro like this. Some people lose slower, some stall for months, some don't get much appetite suppression at all. I hit no shortages, no insurance nightmares mid-journey, and my body just...responded. If you're reading this and your journey is slower, it doesn't mean you're doing anything wrong. Different bodies, different timelines. I got a good roll of the dice and I'm not going to pretend otherwise.

The biggest change wasn't on the scale. It was the silence.

The food noise reduction is, hands down, the single most impactful part of this journey for me. I spent decades with a radio in my head that only played one station. When that finally quieted down, I understood for the first time what it must be like to have a normal relationship with food. That mental freedom is what made everything else possible. The weight loss is almost a side effect of finally being able to think.

But it's not magic. I'm doing the work.

The medication opened the door but I still had to walk through it:

Mounjaro didn't do any of that for me. What it did was remove the constant mental battle so I actually had the willpower left over to build these habits.

To anyone just starting or thinking about it:

Be patient with your body. Celebrate the non-scale victories. The quieter mind, the looser shirts, the better labs, the stairs that don't wind you anymore. And treat the medication as the tool it is: it levels the playing field, but you still have to play the game.

Happy to answer any questions. Rooting for every single one of you.

I've lost 127 pounds over the last year. I was 300.To know my health conditions is to know why this was so important to me. I have heart and lung diseases so for me to complete this run was a small victory! Cause I told myself months ago as I lost i was gone do it. Now it is done!

Double dosing question

Hi everyone, I'm new here and wanted to ask some opinions. I've been on mounjaro for 9 months now, and I've lost 30 lbs in the first 4 months but my weight loss has plateaued now only losing an additional like 1 lb per month if that, since. I've been on the 2.5mg dose this entire time, and I know its the starter dose but it worked for me and I was worried if I increased the dose, I'd have more side effects. I wanted to stay on that until it didn't work anymore. Well it seems to have stopped. My issue is now I have 2 boxes left of the 2.5mg. Has anyone taken 2 doses at once to get 5mg? And if so, did you have any severe side effects? How did you administer it? Was thinking of doing that until I got a new 5mg prescription. And any tips to avoid side effects is appreciated. I thankfully did not have any on the 2.5mg. Advice is appreciated 🙏🏽 Thank you!

Officially “Normal” BMI!

My SW is 109kg (September 2025) but I was 102kg by the time I started Mounjaro end of November.

I’m now under 75kg and have a “normal” BMI for the first time in over 6 years! Crazy.

17st lost. Getting close now!

I want to land at about 12st 7 before skin removal and lipo which I’m hoping take me down to around 11.

I was 35st 8 in this pic, (Dec 22) I’m now 13st 4 but I started MJ at 30st 4. 3yrs ago I could never have dreamed of just how different life would be. I will be forever thankful to Lilly for this drug (whilst blasting them for how bloody expensive it is 😂🤑)

Literally never felt fitter. Keep marching on 💪🏻🫶🏻

42 lbs gone

SW 250 CW 208 7 mg SD April 15
Weightloss has slowed down a little bit lately and I just needed something to keep me focused so decided to do a before and after montage and so happy with the results! I am tall so measurements go down slowly but I have gone from wearing 2x-3x clothes to mostly L and XL (depending on the brand) and I even have a couple of M blazers. It is a long journey but take thise pics, they may come in handy down thw road! I didn’t take one right at the start and I am probably 8 lbs lighter that my SW on that before one, now I wish I had one!

Will Retatrutide on the market bring down the price of Mounjaro?

Below is the latest schedule of approval for Ret. I'm wondering if we'll see Mounjaro go down in price like what happened to Wegovy?

  • NDA Submission (Late 2026 - Q1 2027): Eli Lilly projects that the formal data submissions to the FDA and the EMA will take place following the conclusion of their expansive Phase 3 clinical programs.
  • FDA Review (2027–2028): Once submitted, the FDA generally operates on a 10-month standard review period, making late 2027 or early 2028 the most realistic target window for regulatory authorization

Stopped Mounjaro after 7 months due to low b12 diagnosis ( 175 when normal range is 300 + ) ... wanting to return, if you had low B12 how did you overcome it and did you stop/pause go back?

I was on Mounjaro for 7 months and after unbelievable fatigue and muscle pains.. and 35lb weight loss.. I did a blood test and I am depleted in b12. I am at 175 in b12 when the normal range starts at 300 ( last tested 1 month ago ). I stopped my injections and massively upped the protein, started taking supplements, feeling a lot better. i want to return but I am cautious. To be fair I was undereating, not taking supplements and not eating that much protein either. I am still about 30 lb away from the 'normal' BMI btw, 49 F. Had never been as tired in my life. I thought it was stress but my legs would hurt badly I had no energy...extreme fatigue. I was glad to at least understand what was happening to my body. I am so grateful for the medication yet I am wary what happened. My plan is to keep testing every month to check my b12 levels until it's back to normal.

Has this happened to you , and if so, did you stop/pause, and did you go back? How was it?

I think my dosage was just too high ... I have insulin resistance... I was at 7.5mg for the last 3 months and that dosage was really rough on my body my appetite was so low, eating was a chore I would get full too quickly. I couldn't go to the gym as I was too tired to even go on the treadmill to walk.

NSV: Crossed my legs today!

I am almost down to half of my highest weight (328.5) at what is now my lowest weight of this century (170.5) and this morning I spontaneously crossed my legs. And it was comforable! I don't think I've done that in this century!

Still have about 30 lbs to go, but I'm very happy.

No idea why I had to add this tag...

another update!

hey guys here’s another little update for you all. i’ve now had my first 4 doses of 2.5mg and here are my thoughts…

it’s still harder that what i thought. i thought mounjaro would be “an easy way” to lose weight. i was so wrong. yes it perhaps makes it slightly easier but the discipline and portion control that needs to follow is all down to you. there have been days i wanted to give up. there were days when i probably overate, but most days i was consistent and healthy. that’s the differences between being in Mj and not, there is much more consistency to my diet.

but anyway, my SW was 196lbs, and im now down to 188lbs, so an 8lb loss so far. nothing crazy but it’s definitely a healthy weight loss. i was expecting impossible things when i started and ive now realised that it is what i make it, its not magic.

onto 5mg now so we will see how i get on! :) thanks for the support guys!

first 2 photos are my first week, and the last 2 are today :) i don’t think i can see any difference yet but we will see.
