When did it slow down? And what happened when you stopped injecting or decreased the dose?
i’m 5 weeks in and averaging 4.5lb a week (total loss 22lb). Gone from BMI 30 to 25.5 already.
What happens next? I’ve maybe another stone to lose, but I’m worried I’ll regain as quickly as I lost.
Carrying on eating in a deficit won’t help (I don’t think?) as my deficit now is no bigger then it’s been for months at a time on diets previously with minimal loss if any. I suspect something in my metabolism is altered by Mounjaro, but don’t know if that’s true.
I’m drinking water now, which I never did before, but I find it hard to believe I’ll maintain with that one adaptation.
Has anyone any experience that could give me a clue as to what to expect?

I lost at a pretty fast rate to begin with and had to try and eat more calorific food to slow it down as I didn’t want to lose hair/muscle/ risk anything else!

It did slow down a bit but I had a very high starting bmi (46 ish) so had a lot to lose and have been on MJ for over a year now.

I haven’t stopped (not planning to!) and have recently dropped from 10mg to 7.5 to try and eat more to stop losing. I reckon I might need 5 as am now 8lbs under goal.

I’m not 100% clear what your question is but I think I would stay on the lowest dose you can and try to eat a few more calories to slow it down a bit. When you hit your goal weight, have a good chat with your provider about what you should do to maintain.

If I ate more calories I’d be eating more on Mounjaro than I was before it though, which doesn’t bode well for maintenance.
I’m wondering if loss will slow naturally?
Im also wondering if it will all go straight back on when I stop Mounjaro?
I can’t stay on a maintenance dose if I keep losing, and I don’t want to come off if I gain everything back!

I lost a crazy amount the first week on 2.5. About 8 kilos. I’m halfway through my second pen (moved up to 5mg) and have slowed to about 2 kilos per week.

I’m a week behind you, so maybe mine will slow soon too then. Thanks for giving me hope!
