Back to routine – will 5mg start working or should I move up?

My Wegovy experience wasn’t great, so I switched to Mounjaro. The weight loss has been very slow, which I’ve been okay with because I’m not expecting to be a super responder...BUT after a very relaxed summer, I’m now back at exactly the weight I was in June before the kids’ summer holidays. My weight has basically gone up and down by a couple of pounds all summer and ultimately ended up back where it started.

If I think about the nearly £300 I’ve spent, I find that really frustrating. I know I’m not expecting miracles, but it does make me question whether it’s actually having much impact. I’m still on 5mg and can’t really justify the cost of going up to 7.5mg if that’s just going to give me the same minimal results.

I’m wondering whether it’s worth staying at 5mg now that the kids are back at school and I’m back into a more normal work/routine, and seeing what happens when I’m actually back to my usual eating and exercise habits. Maybe the summer has just masked what 5mg is doing?

Has anyone else found that they started seeing better progress once they got back into a proper routine, despite having been pretty stagnant over the summer? Or I guess I'm also asking if anyone else has not felt the impact of Mounjaro as much as they were hoping to?

What do you mean when you say the summer has "masked" what 5mg is doing? Do you mean you've pushed through the suppression and satiety and eaten more because it's Summer? Or that the MJ isn't giving you satiety/appetite suppression at all?

If it's the latter then you need to go up a dose. If it's the former then yes, obviously, if you're not letting the MJ do its thing then it won't work.

It sounds like you've been eating maintenance calories. Have you calculated your TDEE and at least ballparked how much less you need to eat to be in a decent deficit?

Hey @GiveMeWordGames, I think I mean the latter really. If I've been able to eat enough to be 'normal' or only move 1/2lb up or down, then the appetite suppression can't be working properly. I understand it's not full suppression, but I'd expect to feel differently somehow if it was working like expected.

It would seem pretty straightforward that you need to go up a dose. Tricky if that’s something that will be difficult to afford.

If you stick with 5mg due to costs then you’ll have to really work with the medication, track what you’re eating, plan for high protein low carb and bulk out with veg. Try to avoid sugar or carb spikes as much as possible.

Yes @SilenceInside and there's an element of needing to 'restart' that reminds me of pre-MJ times, and I think I wasn't expecting to feel that like while taking Mounjaro consistently.

Yes, I would agree with @SilenceInside - it seems pretty clear that you need to go up a dose if at all possible.

I only lost a few pounds on 5mg but on 7.5mg really stated to lose the kgs. I think you need to go up to 7.5mg.

I has a similar thing and was unhappy with it. Then someone asked if I was in a calorie deficit and I had to admit I had no fucking clue because I'd hoped the meds would do that for me.

Now I use Nutracheck and know I'm in a deficit and the weight is going off again. I'm not on a hugely high dose and don't really want to be for financial reasons. I expect the people who have to force themselves to eat and lose stones in days are different people to me.

You haven’t really said what you are eating, which is key to your weight loss. I wouldn’t necessarily move up if you just need to rejuvenate the food slightly, perhaps being out of routine has meant you grabbing higher calorie food which you can sort out now?

You are supposed to move up to find your optimal dose and it’s the one before the one you can’t tolerate. You know when you get there as it’s works perfectly 24/7 and instinctively know you can’t move up more nor do you need to,

it isn’t a case you can just decide it works at a certain dose and thays it, for you 5 doesn’t work, it maybe 10 or 15 is the dose for you none of us know.

but what we do know is it is pointless to waste money on too low a dose for no reason,
