July 2026 Mounjaro starters

942 replies

BritbirdUK · 28/06/2026 11:49

I started my mounjaro journey this weekend (Friday) but thought I would start a July thread as it is so close to the start of the new month.

My background - I love good food. My issue isn't necessary that I eat the wrong stuff it is just that I eat too much. I enjoy nice restaurants, Michelin stars and cooking from scratch. But my portion control is terrible. I overeat, regret it and can't leave food on my plate. I also run a food and drink related business. And I make excuses.

In the past I have lost large amounts of weight but this time I have struggled. Peri menopause, going through an adult ADHD diagnosis, a herniated disc (twice) and running your own small business isn't always conducive to WL. I was approved last year for Mounjaro via my GP and then, after my appointment, there were changes and it was pulled. It set me back massively and then, after some big bills at work, I just didn't feel like I could justify the costs and tried, but failed, to lose weight just by dieting.

Recently I went back to my GP and they did some tests and after a few different appointments I was fortunate enough to be approved again and given a prescription last week. I had my first jab on Friday and am determined to make a difference, change my mindset and get back to enjoying life again. There is a long way to go but I am taking one day at a time.

Hopefully there will be some other July starters here and we can support each other, share tips etc.

Weigh and jab tomorrow. I really feel like it's been so much harder this week so I'm kind of dreading it. Also considering going up to 5mg if I don't lose anything this week but will wait and see what the scales bring.

On the upside, I managed to get a perfect week on the Apple Watch rings last week, and I ran 3km today without stopping! 3 months ago I might have managed 500m

Buzzyfeeder · 08/09/2026 07:26

@RedFatball well done on your run, even if the scales don’t move you have and so the scales will catch you up I’m sure! I ran for the first time in a long time this week too with the help of Jay Copley via his free download he is an amazing motivator!
I weigh today but am also feeling the snacky habits and noise creeping back in. I’ve got a brand new 2.5 so will have to persevere maybe I should have gone to 5 but I want to try and retrain myself not rely on the appetite suppressant to lose the weight, I want a long term solution - that’s my theory - it may be a highly flawed approach! We will see.

I've just got my 3rd 2.5mg pen. I too feel I should have gone up to 5mg as the weight loss has slowed due to getting hungry sooner, but I'm going away from home/sort of holiday next week (for two weeks) and I didn't want to be dealing with unexpected symptoms while I'm not in the best position to deal with it.
I struggled with deciding the best thing to do but plumped for staying with 2.5 to be on the safe side.

I've lost 11lbs so far in 8 weeks so not the massive losses I've seen on here, but if it continues this way I'll be happy with that.

Wigwambam65 · 08/09/2026 19:13

3lbs down today. Now 10st 7lbs.

Got 2 doses left of my current pen and not sure at all I want to get another. I don’t want to pay Voy a penalty though which may be cutting off my nose to spite my face. I need to decide if I am going to cancel in the next day or so.

10lb for me in 11 weeks. So very slow. But I think my base calorie count is super low. That said I’d been stuck for over a year before so at least it’s now going down.

AgedPudding · 09/09/2026 19:15

But I think my base calorie count is super low

Yes, mine too. I recently had a procedure on my knee - nothing as dramatic as knee replacement but enough to limit my steps and exercise for a few weeks.
Maximum I can manage is 4000/5000 steps daily which is nowhere near my usual amount and doesn't use up much energy anyway. I'm too old to run:)

AelinAG · 09/09/2026 21:07

I’m on pen three, increased doses each time and this third pen is not working for me. Terrible nausea/stomach upset on day one of the jab and the other days I can barely eat. The thought of food is repulsive but I also know I’m not eating well enough and can really tell. I’m going to count clicks to reduce my next dose on Sunday, desperate to feel better as it’s my birthday on Tuesday 😭

Margrethe · 09/09/2026 21:20

That sounds awful. Is 5mg making you feel sick?

You may have gone up too quickly? I went up to 5mg for my second pen and it was horrible so I have reduced to 40 clicks and that is perfect

Buzzyfeeder · 10/09/2026 12:42

@JuicyPie that is really interesting! What dose are you getting at 40 clicks on a 5mg?

JuicyPie · 10/09/2026 12:59

Buzzyfeeder · 10/09/2026 12:42

@JuicyPie that is really interesting! What dose are you getting at 40 clicks on a 5mg?

It is 3.3mg, i have done two weeks at that so far and going to do a couple more and then move up and hopefully my body will tolerate it a bit better!

Thank you. I think this may be my next step, just the six 2.5 doses I have already bought to get through first!

I think I’ll have to give this a go, I barely even had a side effect on dose 1 and 2 but this is terrible! Will report back…

BerfyTigot · 11/09/2026 09:27

I'm down another 0.5kg (1lb). Slow but I'm ok with that.

I tend to have a couple of days of barely being able to eat and then try to make sure i have enough protein the rest of the week.

SW 113.7
CW 104.1
Nearly made it to 10kg loss.

Well done to everyone for keeping going despite side effects and increases in food noise 👏

Squiggle13 · 11/09/2026 10:03

I’m moving up to 5 on my next pen, had 2 pens at 2.5 with only a touch of tummy troubles a couple of times so fingers crossed.

I can only take 5 for a month then need to have about 3 weeks off as going on holiday to Asia and I don’t want to take the pen with me. I’ll prob go back down to 2.5 when I’m back, that is what the pharmacist suggested. Something like no more than a 2 week break and mine would be 17 days between doses.

Also I’ve decided to move my weigh ins to a Friday, they are so much better lol

2lbs off this week which I’m happy about as had 1lb or nothing off the last month. Still going in the right direction and I absolutely know I couldn’t do alone.

SW: 14st 4.5lb
CW: 13st 2.5lb
Total loss; 17lb

I will be so happy if I can lose another 4lb before my trip, that will be 1.5stone! And in 12 stone bracket which I’ve not seen in years!!

MammaGnomes · 11/09/2026 10:24

Weigh day today and I’ve lost 3lb.
ive had a terrible week though. I’m still on 2.5 but I haven’t fancied eating at all. I’m definitely no where near hitting my protein goals and I haven’t been drinking as much water as I usually do.
yesterday I started with quite severe stomach pains and I’ve not been off the toilet since last night. Really grim.
ive never had bad side effects before so not sure if its the MJ or some kind of bug? I was also having waves of chills along with the stomach pains.

still feel pretty terrible but I think the toilet trips have stopped.

on the plus side I’ve had loads of people tell me I look great which is really encouraging

SW 13st7
CW 11st 13 - Yey for a new stone bracket
GW 10st 7

Margrethe · 11/09/2026 11:15

I have lost 2.7 kilos over 7 weeks. Better than gaining, but not terribly impressive either. My next pen will be a 5mg pen, and I will count clicks to 40, and see how that goes.

AgedPudding · 11/09/2026 11:55

Same here, slow progress for me too. However, it's progress I wouldn't have made without the mj. It's just a little bit of extra willpower. Haven't gone up from 2.5 yet though and I'm 8 weeks in. So who knows?

BatshitIsTheOnlyExplanation · 11/09/2026 12:03

Hi everyone,
I have lost a total of 13 pounds since 17th July, which is OK, but not amazing. I've just started my second 2.5mg pen, still taking 35 clicks. I don't think I can go higher as within an hour I get the MJ fog and am a bit shaky, but on the plus side I can get 7 doses out of a pen.

BatshitIsTheOnlyExplanation · 11/09/2026 12:06

A question - how do people manage to hit both protein and fibre goals? I sometimes get to 60-70g protein, which is under, but not terrible. Fibre wise I have never been over 10g, even when lunch was salad + protein and dinner was ratatouille + protein.

BritbirdUK · 11/09/2026 12:08

Morning all.

Weigh in day for me. I have been jabbing now since the end of June. 4 weeks on 2.5, then I do my last dose of 5 today (2 pens) I made the decision, although I am losing still, to move up to 7.5. I definitely feel like I made a mistake going from 2.5 to 5 after just one month as 5 just hasn't felt right for me. I have struggled to get rid of the food noise and am obsessing over food again. I feel hungry quite a bit but when I have eaten I have got full really quickly even though I am still hungry. Through choice I have constantly eaten healthy food but still, just because it is healthy, doesn't mean I can eat unlimited. I will be interested to see how I get on with 7.5 as a few people I know have said it was the one that worked well for them. Whatever, I am sticking with it for 2 pens minimum.

Today I actually weighed myself twice as I couldn't believe the loss over the past week. I don't think I have eaten any differently to other weeks and obviously there is always going to be a difference based on cycles, but I lost 8.4lbs bringing my total loss to 4 stone 3lbs. There is still a very long way to go for me but it honestly is changing my life and I feel so much better in so many ways.

Add some fibre heavy hitters - eg some All Bran and chia seeds with Greek yogurt for breakfast, and add some legumes like chickpeas to your lunch salad and a tin of cannellini beans to the ratatouille.

A single portion of 30g All Bran, 1/4 tin of chick peas and 1/4 tin of cannellini beans will add about 17g of fibre to your day, and another 13g of protein, for 230 ish calories.

Nowimhereandimlost · 11/09/2026 14:03

I'm on my 3rd pen, sticking at 2.5 as it's working for me and I want to lose slowly. That said, I'm nearly 1.5st down and only 5lbs off my initial goal weight (I'm short). I can't believe it. I've been trying to do this for decades.

People are noticing now. My clothes don't fit. I'm in a healthy BMI range for the first time in years.

I'm now wondering when to stop. I've ordered one more 2.5 pen and then might call it quits. When you tot up all the individual costs, it's a fair whack!

RedUn · 11/09/2026 14:39

Hi Everyone, I haven't been on here for a while, I hope you are doing well. Since I was last here I had a weigh in with a 2.2lb loss which was the biggest I have had for about 4 weeks. It brought my total loss to 20.8 lb in 9 weeks. I went away for a week on the day of jab no.10 to celebrate my 60th. I had some nice food (whilst not completely over indulging) and had a couple of drinks most days and champagne on my birthday. My first full day at home was jab day and weigh in, I had gone up the 2.2lb that I had lost the week before. I was quite relieved with that as it did feel like I had had quite a bit more than I have been having since starting MJ. I was walking (a bit) on holiday and also swimming too so that may have helped. On being weighed this morning (not official weigh in day, that's a Tuesday) the increase has come back down and I am now a new low of 11st 12.8lb, pretty quick change.

I have stayed on 3.5mg from the 5mg pen and will finish that pen next week having had 7 jabs from it. I have ordered another 5mg pen and plan to continue on the same level until I feel I need to increase again. I have had a little nausea at this level but generally quite mild and goes fairly quickly.
