7.5 mj not working, do I drop back down?

Slow, steady loss on 2.5 and 5 (just over 1st in 10 weeks). Once on 7.5 I put on 1lb, then lost it, then back on, then off. I initially put this down to water retention as I got back into the gym but surely it’s not if Ive been yo-yoing all month.
Ive not had any side effects on the lower doses but on 7.5 Ive been lightheaded, tired and freezing cold. Im about to start the next 7.5 pen and was wondering whether to go back to 5mg or keep going with 7.5 and hope it improves.
I’m a bit disappointed that the whole of the last pen has only got me 1lb off which isn’t very cost effective to say the least!

Do you record everything you eat? I would do that if you don't already. The medication strength won't be preventing weight loss but your 'behaviour' because of how it's made you feel might do.

Yes, my intake is exactly the same as before with the exception of a clear protein drink when Ive been to the gym which is an additional 87cal.

What have you actually lost? It may not be the drug so much as you've just hit a stall point that would have happened anyway.

A lot of people seem to 'stick' a bit at 10%, for example, or at a previous 'lowest weight'.

ZeroDucksLeft · 21/01/2025 18:51

16lb total which is about 5%. This is the lowest weight Ive been for probably 20 years. Every other attempt I get to a few lb above what I am now and seem to find it incredibly difficult to get any more off, even doing fast800 or other more extreme diets.

Why would going down to 5mg help? You know that’s less of the drug right? I don’t get it.

Plateaus are normal.

How much are you eating per day? If you are eating too many calories compared to your size and activity you won't lose weight. You also mention going to the gym - are you building muscle as that weighs more than fat so you may be shrinking size wise as you firm up but not losing in the scales. I have some Renpho scales which tell me my body fat, BMR, visceral fat etc. They only cost £20.

Personally if I wasn't losing weight on 7.5mg I would go up to 10mg not go down to 5mg. But I have been up to 15mg on Mounjaro.

Because I was losing and had no side effects, which now I’m not and I have!
I know, it’s just frustrating because it’s expensive and I was already losing slowly.

Ok, maybe you’ve not understood, but your body is now used to it, that’s why 7,5 isn’t working, 5 will now be like injecting water. 5 isn’t going to have a stronger effect than 7,5

you need to move up to ten.

Maybe your TDEE maintenance calories have gone down now that you have lost weight, Op?

Shrinkingrose · 21/01/2025 19:22

Basically you do 4 weeks on each dose, and if it stops working as effectively it means you’re not at optimal dose, so you need to move up when that happens till you reach your optimal dose, where it just keeps working, all day every day, for me that’s ten, for others it’s five, or fifteen.

but you can’t go back in time, you’d only drop down if your suppression was so high you were struggling to eat, and feeling sick etc, as that’s means you’re at a a too high level, and need to drop down , as again your optimal dose is the one below that which you can’t tolerate.

so you just need to move up, you need ten. If you’ve bought a 7,5 pen, you can manage clicks to get ten out of it, but it will mean two injections each week,
