Gained a stone?!

111 replies

NoOneToCallWhenThePlaneLands · 16/10/2025 17:33

I’m just going to spill everything here because my head is a mess.

I started mounjaro last summer. I lost about seven stone.

I had been feeling like it was less effective for me for a while now. But I pressed on, and stayed on it while I was having surgery three months ago. I was 15 stone 8 when I went for my surgery.

Since that, I have been less active than usual. I was still eating at maintenance/a slight deficit.

i started back at the gym three weeks ago. I’ve gone into a full on programme of cardio and muscular exercises.

I’ve weighed myself at the gym tonight and I’m 16 stone 5.

im gutted. I feel like I could cry. I haven’t been 100%, but definitely not at a point to gain that much. I feel like there’s no point continuing to pay for Mounjaro when I’m just failing on it, but also I wouldn’t be able to continue at my current calorie level (1400 a day), without it.

my current stats are

5 foot 4.7

16 stone 5.

what do I do?! I don’t know whether switching to wegovy could be useful?! I’m currently doing a split dose of 10mg every 4 days.

I just feel like throwing in the towel. Maybe this is where I’m meant to end up

I’m also questioning the accuracy of the machine, because when I was measured at the hospital I was 162 which is apparently closer to 5 foot 3?

What dose are you on? Can you speak to your provider, they could suggest taking doses slightly closer together I know they have for some.

I watched a great video on the coming off MJ thread, I’ll be back with the link.

You need to get to grips with the diet side of things and find ways to stick to your deficit. As you lose weight the number of calories gets smaller and you need to be more careful.

plateaus are absolutely normal and it could be inflammation and a plateau is making things appear worse. You need to tough it out.

I’m split dosing 10mg.

this isn’t a plateau. I’ve gained nearly a stone.

If you are 5ft3 then 1400 calories could be just above maintenance. It’s hard to track really closely.

FurForksSake · 16/10/2025 17:42

Go up to 12.5 and stop split dosing?

SilenceInside · 16/10/2025 17:43

Firstly, if the scales at the gym aren’t the ones you usually use then I would weigh in again at home. Then, I’d just get back on it with watching your calorie total and exercise and give it at least a few weeks to see if the weight begins to drop off.

Moving to Wegovy seems like a bit of a curveball, as it’s less effective on average than Mounjaro.

By split dose, do you mean you are doing 5mg every 4 days? Or 10mg every 4 days? If it’s 5mg every 4 days then you have a lot of scope to increase your dose.

My maintenance (based on me being 5 foot 3) is apparently 1700 a day. So 1400, plus my exercise, should still be a deficit. And nowhere near enough to cause a gain of a stone.

5 every 4. I can’t really afford the 15mg though. So this has to do.

Could you do 7.5mg every week? What was the reason for deciding to inject every 4 days?

FurForksSake · 16/10/2025 17:49

You are either eating more than you think or your maintenance is lower than you think. The exercise won’t make much of a difference at all. Up your steps and not structured exercise, decrease your calories.

Remember you are weighing on different scales, with clothes on presumably and after eating / drinking. That could be 7lbs different potentially.

Because it’s seems to be the sweet spot for me. I get enough suppression that I’m not over my calories, the 4 days means it lasts long enough in my system but I’m still using my willpower to stay under my calorie count.

I’m not. I weigh everything meticulously. I have not been eating enough to gain this amount of weight. I hit 10k steps a day. My maintenance cannot be lower than it is, because every single TDEE calculator spits out a number within 100 calories of 1700.

@NoOneToCallWhenThePlaneLands Hi I was on the same position but my surgery got cancelled on the day so now I've had to start back on it at 2.5 and its useless ive put on around a half stone but still under the weight I need to be for surgery so thats not so bad im desperate to get up the doses

SilenceInside · 16/10/2025 17:53

Could there be any lingering inflammation from the surgery?

If you are consistently sticking to a definite and meaningful calorie deficit then you will lose weight. Eventually. There is nothing else to be done other than stick with it.

Potentially but it was pretty minor.

according to my calculations I’d need to be eating around 4000 calories a day to be gaining that amount of weight so it’s not that!

two things to consider:

  1. are your clothes tighter / body measurements bigger, or only the scales? i.e. could it be muscle mass due to increased exercise? and you're actually doing really well
  2. although the calculators say 1700 for you, all humans are different, so if your metabolism is on the low side maybe it's not ideal for you?

hopefully its number 1 :)

Edited

Measurements are about the same.

im 11 days from my period so I don’t know if its potentially that but it just feels like a massive slap in the face. Even if I account for 3-4 lbs for food eaten today and water consumed it’s still 7 pounds gained!

FurForksSake · 16/10/2025 17:58

When did you last weigh before this weigh in at the gym?

FurForksSake · 16/10/2025 17:58

Probably 3-4 days ago. I was about 15 stone 9, so much more normal fluctuation

OP posts:
SilenceInside · 16/10/2025 18:01

Well you haven’t put on 10 pounds in the course of 3 to 4 days! It will be normal fluctuations, a different scale, wearing clothes, TOM, etc etc.

Yesitsmeimback · 16/10/2025 18:03

Could your scales at home be wrong?

SnacklessWonder · 16/10/2025 18:05

I ONLY weigh myself on the same scales, in exactly the same place every day. That way, I know that it's "accurate". Same time of day, same state of undress. Okay, it might be 'out' by a few lbs from other scales, so what I think is my weight may not actually be my weight - but that doesn't matter so much - because the amount I've lost or gained is all relative to that starting weight.

My DH bought me new scales and they put me at 4lb heavier so I've stuck with my old ones, not for vanity but for continuity!

You've not gained a stone in 3-4 days unless you've overeaten by almost 50,000 calories which would be bloody impressive!

Yesitsmeimback · 16/10/2025 18:03

I don’t think so, the ones at the hospital lined up with what the ones at home said.

OP posts:
FurForksSake · 16/10/2025 18:05

So actually only a pound heavier than before surgery. Ignore this weight, it’s explainable.

Your bmi is in the high 30s and I’d be inclined to keep going up the doses so that it can help with you losing the weight. Particularly as you think without it you’d be struggling with the deficit.
