I’ve just finished my first week of mounjaro 2.5mg and I’ve lost 7 lbs already! Had a fair amount of suppression and ate boiled eggs for breakfast and keto style, protein heavy dinner with some fruit inbetween. Not counting calories but I’m probably not eating enough of them. I’m a bit worried I’m losing too fast and I’m going to get saggy skin 😬 I’ve got 3 st to lose and early 40s. Has anyone further down the line got loose skin/similar issues and lost weight at a similar rate? Really worried about it

It will slow down. You have just lost ‘water’ or the glycogen reservoir. You will likely drop a pound or two a week from now on.

You haven't lost 7lb of fat and it won't carry on like that. In fact you may not see any drop on the scales in week 2. Don't worry!

I started in Feb and lost 4kg in the first week. I average around a kilo a week now. It will slow down to a more sustainable rate over the next few weeks. Also don't lose hope if you find you don't lose much or even gain over the next few weeks, your body can sometimes put up a fight against the weight loss, it'll sort itself out eventually.

Yeah it’s already slowed down (the other day I’d dropped 3 lbs overnight!) but today I appear to have “put on” a pound!

What does losing water weight actually mean? Might be being a bit stupid here lol

I too lost a similar amount in the first week, 4 months in its been hit and miss most weeks despite only eating a diet of about 1000 calories a day. You've lost water, don't worry it will slow down to about 1 or 2 pounds a week if you're very strict. If I veer even slightly I don't lose at all. It's easier to lose on mounjaro, because you don't feel as hungry, but it's still dieting, and it's boring. I have also succumbed to crepey skin despite collagen supplements. I needed to lose a similar amount to you, started at 12 5 and am at 10 2 now I look like a deflated balloon unclothed, I'm 10 years older though.

I'm 3 weeks in and not noticed any loss. Is this normal? I've had no side effects.

Week 1 - 6
Week 2 - 4
Week 3 - 3
Week 4 - 3

That first month was a revelation.

I'm now on week 29 and averaging out at 1.8lbs per week since I began. 4st 3lb lost in 7 months on the jabs plus another stone I lost before I started.

Life changing doesn't begin to explain how I feel about it.
