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!

That's because weight loss is known to increase the risk of gallstones (my cousin got gall stones from losing 10 stone on a diet, pre weight loss injections), her surgeon said it's really common after big weight loss.

WLI also increase the risk of pancreatitis. It's a known risk. Pancreatitis is pretty rare generally though, so a slight increased risk isn't something most people need to be concerned about.

I know, that’s why I mentioned it.

I know 3 people who are now very under weight. Average height and 7 stone ish... This is becoming the fashion now and it's so easy....

Cheaper than gym membership and organic health food.

There will be a huge price to pay!

Of course. All 3 are buying Mounjaro and gorging on high fat, cheap, processed foods and still losing weight at a rate of knots....

@ didimum.

"... I say this because the jabs treat the symptom, not the cause, of weight gain ..."

You might find you're wrong about that statement. There is evidence to suggest GLP-1s work on the brain as well as the gut.

The following is an extract from The Guardian.

The former head of the US Food and Drug Administration, David A Kessler, writes in his recent book Diet, Drugs and Dopamine, “the fact that the new anti-obesity drugs are highly effective underscores the fact that being overweight or obese is not a product of lack of discipline or willpower”. If a drug can target it, “it is instead a matter of biology”.

Here is what David A. Kessler also says in his book:

"I am deeply troubled the FDA approved GLP-1s for long-term chronic use without requiring the pharmaceutical companies to conduct enough studies. The pharmaceutical industry argues that these drugs have been around for decades, but not in such large doses and not for the treatment of obesity. Some people may be able to handle the drugs for life, but we juct don't know. Right now we only have about five years of data at the current doses."

But it's none of the OP's or anyone else's business if you do decide to use it. It's between you and your medical provider. In your personal circumstances it may be perfectly reasonable to use it.

I don't feel as though the OP is making it any more of their business than any other contributor to this anonymous forum.

Having just read the below thread, I think I'll stick with what I'm doing.

Misery and fools both love company.

I don't have a dog in this race, but it seems to be the case that people making the decision to take semaglutides often take it as a personal criticism when someone else makes the decision to not deal with their weight issues the same way.

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.

No one is ‘concerned’, it’s usually just a way to berate and scare people who they think have ‘cheated’ in some way.

hollyivy123 · 17/03/2026 12:22

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.

Are you a certified dietician?

No and news alert, you don't need to be a dietician to know the impact of sugar on Western society in the past 75 years. Just look at any data showing the rise of obesity and the progression of ultra-processed foods which are packed with sugar - even the supposedly "healthy" ones. Walk around any supermarket and count the number of aisles dedicated to processed sugary foods vs natural food products.

The obesity epidemic began in the USA in the seventies and in the eighties/nineties in the UK and Europe and now it's massively impacting developing countries such as India and Middle Eastern/North African countries.

If you're interested have a listen to Dr Robert Lustig - a retired endocrinologist who's written several books on this topic including Metabolic:

Mounjaro isn't a Semaglutide. But that aside, I don't think its the case that people taking them care if others choose not to. I think its the moral judgment (voiced without necessity or purpose), that grates people. If you don't need, or want, to do something - why does that require announcement to those who do?

It's the same with any divide in any other area of life - breastfeeding, home educating, staying at home with your children, going back to work after maternity leave, eating organic, managing diabetes with/without medication...do what you want to do and don't pass judgement on others that are choosing differently.

I think you'd be hard pushed to find a single comment from someone using WLI that is casting moral judgement on someone who chooses not to.

Tryagain26 · 17/03/2026 12:24

Reliablesource · 17/03/2026 08:28

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?

There are many drugs that are safe for people with certain conditions but not for the general public to take. Eg would you take medicine to reduce your blood pressure if you didn't have high blood pressure? Or medicine for heart palpitations, or blood thinning drugs etc.
Also all medications have a risk and side effects and prescribers have to weigh up whether the risk of the disease is greater than the risk from the medication before they prescribe. I'd argue that someone with a healthy BMI shouldn't be prescribed weight loss medication because the risk of side effects is much greater than the risk of someone getting ill from having a healthy bmi

I believe there are court cases pending against Monjourno as people have suffered horrendous side affects-gastric paralysis, blindness, daily vomiting....
If yr obese and diabetic it might be worth the risk but not if yr just a bit overweight.

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.

TheEgg2 · 17/03/2026 12:28

I think people have freedom of choice over their own bodies but pharmacies, online or otherwise, have a clear duty of care. I’d suggest that only people with designated health conditions that WLI could improve should be offered WLI with a <BMI 25 to help regulate the market and keep people as safe as possible.

Morepositivemum · 17/03/2026 12:29

I did sigh at the people recommending to the bmi 25 (my bmi!!) because thar’s my own size but in general think wli are amazing and wish two people I know who have died had had the opportunity. I think they’re more of a gift to humanity than not

The way Mounjaro works in the body is the same whether someone has Type 2 Diabetes or is 'just' overweight or obese. It still affects appetite, insulin response & blood sugar in the same way. It’s not being used for a completely different purpose in non-diabetic individuals.

That said, I do agree it shouldn’t be used in people with a healthy weight, as there’s no real benefit to outweigh the potential risks.

Fetaface · 17/03/2026 12:30

Key risk factors include obesity, rapid weight loss, being female, and being over 40.

There used to be a saying "fair, fat and 40" was a good indicator for gallstones. Wasn't that the condition Rosemary Conley had prompting her Hip and Thigh diet which transformed her?

The 4 fs - fat, forty (or over), female and fertile. The more f's the higher the chances.

aredrosegrewup · 17/03/2026 09:38

But taking them long term also might be absolutely fine if it allows them to stay at a healthy weight. As long as their Doctor is happy it's no concern of anybody else.

Why is it so bothersome to people that they are used and if people stay on them long term? It's literally causing the general public not a single concern. What should cause concern is the strain on the NHS if more and more people become obese.

The point you are missing is that it might not be a safe to take them long term if you are not diabetic, there may well be long term side effects and then those people will be a strain on the NHS etc

If yr obese and diabetic it might be worth the risk but not if yr just a bit overweight.

Court cases in the US will be against Eli Lilly, the manufacturer of the medication Mounjaro. You can't sue a medication. The US has a very long history of class action law suits, it's a process in itself often done to push companies to pay out prior to a court case as it's more cost effective than going through the whole process. The court cases in the US are about whether there was sufficient warnings about possible severe side effects. Personally, I don't think these cases have much chance of succeeding given that the warnings were clearly present in the patient information.

Gastroparesis, vomiting and so on are existing recognised side effects that are already warned about clearly in all the patient information about these medications. The risks of these were factored into the MHRA decision to approve these for use in the UK. No one would win a court case in the UK if they complained they didn't know about these side effects.

The risk of blindness is not proven, and needs further research. If it is shown to be a risk, then it would be added to the list of possible very rare side effects.

These medications are not intended for people who are a bit overweight (BMI more than 25 but less than 27/30). Some pharmacies seem willing to prescribe off-licence to those people, and they will be expected to be able to justify each of those prescribing decisions if/when inspected.

time4anothername · 17/03/2026 12:34

yanbu and it is really awful to see people encouraging someone who is healthy on all their measures (glucose, bloods, waist to height ratio), able to exercise and be physically well to lose weight because they want to be at the bottom end of BMI which is a made up figure anyway. Reminiscent of pro ANA making women tired, weak and pharma dependent.
All meds come with side effects. I am considering WLI myself to correct some of the mess that was caused to my body by long term prescribed meds for another condition so I am not anti them but am realistic that there will be the possibility of long term issues to replace the ones I need to manage now. Look at the history of corticosteroids for instance. They were a miracle drug that kept people alive and so widely celebrated in the late 1940s onwards and it took decades for the long term damage that long term use causes to be recognised and more for it to be acted on.

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.

Nanda66 · 17/03/2026 12:35

My BMI was just above 30 when I started. Technically I was obese but I don’t consider that I had an illness. I was simply too fat because I was greedy. No health issues. Seven
months later I have lost over 2 stone, gained confidence and feel and look great. I’m still overweight but I have no interest in being thin, I want to feel healthy and look good. BMI of 25 feels like as far as I want to go. I’ve had no side effects and I eat well and mindfully. Just less food and better food. However I can see how easy it would be to take a higher dose and get addicted to not eating.

Would I recommend it - yes. Would I recommend it to someone with a starting BMI of 25? No, I think there is huge potential for eating disorders if starting at that level.

BoudiccaRuled · 17/03/2026 12:36

Traditional diets work just as well as WLIs, if the dieter sticks to the diet. People who resorted to WLIs tended to be unsuccessful at sticking to traditional diets, which is why they are so relieved to have the magic needle in their lives.
Many of us have no interest in WLIs and can easily lose 10lb every year (letting it creep back on again!) without resorting to drugs. For some it's nigh on impossible, hence becoming obese over time.
I'm sure people won't be taking WLIs unless they really struggle with diets.

No one is ‘concerned’, it’s usually just a way to berate and scare people who they think have ‘cheated’ in some way.

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.

Where are people getting it from if their BMI is as low as 25?! The standard is your BMI has to be at least 30 I thought? Unless you’ve been on it before or you have a certain health condition?

No this has changed to 25 with some pharmacies

Well why not, from a healthcare perspective if someone quickly gets on top of a small weight gain, pays for it themselves and returns to a healthy weight easily thats a win for everyone imo.

No-ones forcing anyone onto them. Theres so much moralising about this stuff.

The weight goes back on when you stop taking it unless you have dealt with the underlying cause:

  • comfort eating,
  • eating ultra processed foods stacked with sugar - humans are hard-wired to eat as much sugar as we can when we come across it in nature but this is usually limited by the seasons whereas sugary foods are now abundant everywhere and cheaper than healthy foods.
