Just get mounjaro!

The more threads I read, the more and more posters seem to respond with “just get mounjaro” for posters wanting to lose as little as 10 lbs to get within a healthy BMI. More traditional methods of weight loss appear to be out of fashion and as though you’d be foolish to do it the perceived hard way when you can just inject a drug.
I was reading a thread where a poster had a BMI of just over 25 who was told to just get WLIs. What happened to them being for those who are obese?
Is this the way things are going now? Gained a few pounds over Christmas or on holiday? Just inject and don’t worry about it!
Anybody going against the grain of weight loss injections is often accused of being jealous. It’s a bit cult like on some threads as though WLI are the only valid way to lose weight and you’d be foolish to try any other way because “diets don’t work” and just adopting a healthier diet and lifestyle is laughable; a fool’s game and you’ll end up fat again. Well, yes, if you go back to your old habits, just like any method of weight loss.

Just a bit of a rant really on this sunny Tuesday!

I agree it's not that easy to 'just take mounjaro'. It's interesting to note that there are very few posts on here mentioning the cost, never mind everything else! £200 quid a month is nothing to be sniffed at, particularly if you've got to be on it a long time, and for many may have to be on it for life. Also what's the point of it if the weight piles back on after you've stopped? I understand it has helped some people, but clearly the demographic of all the rich mumsnetters on here are always going to defend it. It's a personal choice, and due to the lack of researched on long term use for weight loss, I won't be taking it.

Exactly, a personal choice. Has absolutely nothing to do with anyone else. Yet, the majority of people shouting about it are those who aren't on it. Most of the people who are on it are minding their own business, getting on with and trying to improve their lives.

I wish I could take it but I had such terrible diarrhoea and vomiting which lasted several months. I feel so sad that I couldn't continue with it.

All drugs are chemicals and all drugs have a negative impact on the body over time which is why they should only be prescribed when the benefits outweigh the risks. Taking Mountjaro when you are a few kilos overweight is not recommended by responsible doctor but there are many who see this as an opportunity to make money quickly and easily.

Serious Side Effects of Mountjaro (Seek Medical Advice)

  • Pancreatitis: Severe, persistent abdominal pain, often radiating to the back, with or without vomiting.
  • Gallbladder Issues: Severe pain in the upper right stomach, fever, or yellowing of the skin/eyes (jaundice).
  • Kidney Problems: Reduced kidney function, sometimes caused by severe dehydration from vomiting or diarrhea.
  • Severe Allergic Reactions: Difficulty breathing, swelling of the face/throat, or severe rash.
  • Thyroid C-cell Tumors: Mounjaro has a boxed warning for a potential risk of thyroid C-cell tumors based on animal studies.

Thanks for that, have been using Mounjaro safely for 2 years and never thought to do any research. So grateful you have access to Google.

I caught drug resistant TB from my stupid , stupid mother in 2014. She was never inoculated despite saying she was to everyone and not getting treated until she was sectioned. Lost 2 stone at 5' 5", ribs stick out etc. Had to leave two part time jobs and with medical services not brilliant where my mother lived returned to London. Good hospitals and medical support.
Moved in with an ex's mum who's a former nurse who cared for me when she could. Got appointments, got treatment but long struggle. Only a couple of friends helped me, and my now BF came to all the hospital & clinics, etc. He and a few of his family were determined to fatten me up. Him and my case worker got me into sheltered accommodation whilst I recoved - ex had started coming around to him mum's again. & harassing me. Took two and half years to put weight back on bruising & feeling uncomfortable under my own skin. I'm probably a stone over my pre TB weight now - mainly in my bum & thighs.

Thought of weight loss jabs where you can't put the weight back on chills be. And some of the famous people now skinny mini with sunken cheeks is off-putting for lots of people. If it's someone very overweight and the just a bit, then fair enough.

I had had enough nightmares with christian foster parents regulating everything from I ate in pre teen years. Lucky I was moved to Afro-Caribbean foster family who knew & put me onto flexible eating etc.

Do you mean you didn't read the safety information leaflet or the copious amounts of information given to you from your pharmacy? Silly you!

It's ok though because everybody here on this thread and others who don't know you or your past medical history can give their opinion which is much more important and relevant!

My BMI is 23, and I look lean (think 6 pack!) as I have good muscle mass. If you feel chubby with a BMI of 22, I’d suggest a body recomposition not fat loss.

This is the way. I'm 5'10", BMI 25 and around 21% body fat at the moment. I'm only aware of my BMI as I was curious because it isn't very meaningful to me. I weight train 6 days a week and eat like a horse but 95% of the time I eat the right things.

People can't stand to see overweight people doing well. It says more about them than anything else. Overweight people can't win...

don't lose weight = fat and lazy
loses weight with the aid of a jab = still not good enough.

It's the result of a fatphobic society and the general hatred by some towards those who are overweight. The very thing they're scared of becoming themselves because they think overweight people are of less value.

As someone who is both fat and concerned with people taking these drugs with no proper medical oversight, nope. Fatphobic is a word that gets thrown around a lot to the point it's utterly meaningless.

You really don’t need to spend your time being concerned about others, although that’s very kind of you I’m sure, the global health authorities are in control, know the meds, know the safety data, and they are good, so you can stand down, maybe find something else to worry about, rather than fat people taking perfectly safe drugs legitimately prescribed to them and becoming healthy.

I'm going to be mad at the culture that tells women with a BMI of 25 that they need it to be 18 in order to be happy, rather than any weight loss mechanic.

Life is hard. Dieting is a mental battle, whatever size you are. Some people are already fighting a million mental battles. I don't think someone who has a healthy BMI should feel the need to take mounjaro. But if they do, and it's safe, it is neither my circus nor my troop of monkeys, and I'm not here for any 'but what if there are side effects we don't know about yet?' because that all sounds a bit anti-vaxxy to me. We learned from the thalidomide scandal. The drug has been tested and approved in clinical trials for weight loss, and it has been safely used by millions in the general population for decades to manage diabetes.

Not my circus.

SilenceInside · 17/03/2026 12:57

@SapphireSeptember could you expand on what you feel "proper medical oversight" should look like?

That's your opinion. I have mine. How is there no proper medical oversight may I ask? If you're not taking them, how would you know that?

Why would anyone be furious about them? I’ve not seen any evidence of that. Some posters have expressed concerns because as a weight loss drug they are new. Yes, they’ve been used for a long time for diabetes but this a new use so I can understand people saying the long term effects are not known when used for weight loss instead of diabetes. I think they will have other uses in time. Some posters have said it helps their ADHD symptoms for example.

Whether you've seen evidence or not, it's there.

PropitiousJump · 17/03/2026 13:01

I think people do tend to be evangelical when they find something that works for them - with medications, diet, breaking bad habits. They want to be the person who fixed it for the OP after everything else had failed - it's a natural enough instinct.

Going on Mounjaro when you have very little weight to lose seems to me to risk spending an awful lot of money for not very much, because presumably if you need it to lose, say 10lb, you're going to need it to maintain that weight afterwards. I can quite see that if you are obese, it would be worth the money because the weight loss would be life-changing, but less than a stone to lose and you're spending thousands to look a little bit slimmer - is it really worth it?

aredrosegrewup · 17/03/2026 12:26

That's my point, it's absolutely nobody's business but your own. I was saying it might be right for you and it's got nothing to do with anybody else. It also might not be right for you and that's equally nobody's business.

Forums are going to become obsolete if the stock response is, it's none of my business, you do you.
And you do have an opinion as much as you might protest, otherwise you wouldn't be responding to so many posters on here.

MrsSlocombesCat · 17/03/2026 13:12

I have a BMI over 35. My GP hasn't offered me the jabs yet and even if they did I wouldn't. I'm just waiting for the future wave of health issues to arise from it. There are already well known side effects and it worries me that so many people who don't need it are taking it. Also, people seem happy to take the stuff forever when noone knows the long term effects. It makes people look like drug addicts because they lose too much weight and a lot of that weight is muscle as well as fat. It can also lead to Osteoporosis. No thanks. I have stopped drinking and am exercising more, I would rather do it the natural way or not at all.

Huh? Of course I have an opinion, my opinion is that individual health is nobody else's business. I'm replying to a lot of comments because there's a lot of nonsense and misinformation being spouted.

I was actually originally on your side by saying, do what you feel is necessary for you between you and your health provider.

How vile, you're happily sitting waiting for people to become ill with side effects. What a very bizarre take.

I suggest we dont know anything at all about anyone else's personal medical history and that the appropriate use of a jab is between and individual and their medical provider.

Totally.

I think it depends on circumstances. A person with say a 27 BMI who's never been heavier is quite different to a person with a 27 BMI who's been obese before. Ethnicity is also a risk factor.

There seem to be quite a few of us who've lost and gained the same stone a number of times. There are points in my life after first becoming obese and before WLIs when I wouldn't have been much more than ten pounds above healthy BMI ( I'm short). Bounced between the high 20s and low 30s. But I never managed to keep it off, which statistically is the norm. I don't know if I'd have wanted WLIs any of those times had they been an option. But if I had, would've saved me the health risk of the almost inevitable return to obesity. And this is even as a white person. It's riskier for most other ethnicities.

But yeah, if that's your first time being 10lbs above 25 BMI, potentially a different calculation.

SoMentallyDrained · 17/03/2026 13:16

I agree with you OP, but there's no point expanding on my opinion because I'll just be shouted at 🙃

Ohyeahitsme · 17/03/2026 13:21

aredrosegrewup · 17/03/2026 12:35

News alert, there's no one single cause of obesity, but you would know that if you were trained in the field. Instead, misinformation gets spread around which is why each individual should work with their own medical provider for anything related to their health.

Exactly. There's huge leaps in knowledge being made in to the bacterial and viral causes of obesity as well. I suspect there's several causes, some of which impact some people more than others.

What I can’t get my head around is when critics of Mounjaro say it is safe to use for diabetes but maybe not for weight loss. If the drug is safe, it is safe! Your body doesn’t know what you are taking it for.

Also don’t understand the obsession that some people have with WLI who don’t need or plan to take them. What’s it got to do with you whether other people want to use them?

People can have an opinion on things they don’t do themselves.
