Did you lose weight on WLI and then ‘pile it back on again’?

I’ve been on MJ for 11 months now and it’s been slow and steady losses - 3.7 stone and another 2 to go. When people ask me how I’m doing it, I’m open about the fact I’ve overhauled my diet and have had some help from medicine. However, I keep seeing (and occasionally hearing) this everywhere - ‘you’ll only pile it back on again’. Nice, eh!

So while the studies seem to indicate that’s likely, surely it’s only like every other diet and only happens if you return to your old ways of eating? I will always have to watch my weight and so my plan is to get to goal and give myself a healthy buffer of around 7lbs. If I start gaining, I’ll cut back for about a month or so and get back down to goal. For me, I forever sabotaged my own weight loss because losing 5 stone seemed utterly insurmountable whereas 7lbs seems so much easier.

I know there’s a maintenance thread but just wondering if anyone did lose a lot and then have a big regain? Am I being naive to think I can avoid it? For you, how did you tackle the regain or are you still struggling?

Just trying to get a realistic idea of what might be ahead.

I don’t have a condition or a disease.
when I have been obese it’s usually because I’ve put on weight for another reason- eg post pregnancy- then got in a ‘fuck it’ spiral.
i get obsessed with food and think about sweet food all the time if im hungry.
if i go very low calorie I just think about food until i break my diet.
nothing wrong with me, just eating too much.

Obesity is a disease, so you did have it, a disease is ‘an abnormal condition that negatively impairs the normal functioning of an organism (human, animal, or plant), typically characterized by specific symptoms, physical signs, or structural changes”

and obesity falls into this category, I think people get confused and think it is caused by pathogens or is infectious disease only, thays not the case, being obese is a disease as it impacts normal functioning and negatively impairs it.

Long term maintenance of weight loss is incredibly difficult and a minority of people manage it so really well done 👏🏻👏🏻 and also thank you for taking the time to share your experience, it’s inspiring and valuable for those of us who have lost weight and are wishing to begin the longer journey of maintaining it in a healthy and sustainable way, that will look different for everyone. I have lost 7st and am happy to stay on a maintenance dose for as long as I am able because my life is so different now and I know that going back to being obese would cause so many health problems which I have managed to overcome such as high BP, pre diabetes, joint pain, inflammation, IBS. I am active and healthy for the first time in years and feel happy and comfortable at my new weight and size. MJ is the only medication I take now and I am sure I have extended my life expectancy by enough years to see my Grandchildren grow up and be a very active part of their lives. I still enjoy food but I can moderate my intake and understand what my body needs to stay healthy Long term use of WLI may show a risk in the future as more data becomes available but for now with the current information and guidance I feel happy with my choice and feel that the alternative of weight gain would potentially be a much greater risk to my physical and mental wellbeing

Ah thankyou! And well done to you too, you must feel amazing! Yes if you look at the maintenance dose as a low dose of a medication your body needs then why wouldn’t you take it, the benefits of not being obese are endless. My main worry was cancer.. I’d always associated cancer with smoking, drinking and sun damage but saw a stat about obesity being a big cause of it. Hopefully in decades to come there will be a fall in disease rates

The thing that has so far stopped me cause I can cope with A....there is some emerging suggestion that some people begin to tolerate the drug over time and need to increase and increase the dose to have the same effect and get to the point where even the max dose isn't working. This might be part of the metabolism-adjusting thing described

this is more complex, so for some people the drug doesn’t work as optimally as it does for others, and there is a placebo effect to an extent, the mind is very powerful, so they believe it will work and thus behave accordingly, then after a period of time diet fatigue sets in, so they start to consume more, and realise the real effect of the drugs, and then increase tbeir dose.

the drugs don’t stop working, or become tolerated where you need more, if it did it would not be used for diabetics, and it would not be about to be approved for cardio vascular health, it would be too dangerous, the drug always works, as it always has, like many other drugs, inc statins.

in addition you can push through and keep eating on the drugs, should you chose to do so. Unless you’re on too high a dose and it’s knocking you sick. And again the mind is both complex and powerful old habits die hard, the desire for the food is not always linked to physical reactions, but sometimes comfort, enjoyment etc,

so it isn’t the drugs stop working, or people tolerate them more,

however due to the very severe risks obesity has on your healthy and longevity, as said it is the leading cause of cancer, before we look at all the other issues, heart attack stroke diabetes joint degradation etc. then my view is it is better to get to a healthy weight, than stay obese worrying about what to do when you’re a healthy weight.

i would caution though, you need to do it when you’re in the right headspace, otherwise you will scupper yourself. Food can be a crutch for some people, and the overeating is about mental health, they get their dopamine hit from it, their comfort, their friendship etc, and food becomes something you enjoy, but in healthy portions, and more a fuel than anything else.

This has brought me to tears as it gives me hope.

I have a lot to lose and am losing steadily on the lowest dose. I am finally getting to eat how I want to rather than what I feel compelled to eat. My biggest fear has been getting used to it and needing to go up to a higher dose as I can't afford to. But at the same time, I can't afford not too as I'm recovering from cancer and I must get control of my weight.

It's so reassuring to read that it will keep working the way it currently is.

Fishingboatbobbingnight · 08/03/2026 11:22

Why is it so hard for people to understand that if you have a disease (MS, Diabetes, Obesity etc ) and you take a drug to control the symptoms… why on earth would you expect that disease not to come back when you stop taking the medication. ????

If you suffer from blood clots, the doctor will prescribe blood thinners to prevent life threatening clots. Warfarin has 3x the amount of serious side effects compared to MJ but I bet none or at least a tiny percentage of you would not tell a doctor you don’t want it - or for heavens sake, take it, then stop it and be completely surprised to develop a clot ! If you do then you have a kink in your think..

People really do need to read some proper peer reviewed papers on what they are taking rather than listening to all the crap on instagram about ‘gaining new habits’ ‘re educating their brains’ GLP-1 mimics a hunger hormone. It doesn’t miraculously alter your neurological pathways and thought processes. !! If like me you had lived with obesity for many years , then you had probably tried EVERY diet under the sun, lost a few stone and then regained it all and more in a short period of time. ? If like me, you could name the amount of calories in any given food at a 1000 paces and work out in nano seconds the nutritional content of a plate of food - then you don’t need re-educating .. it’s got fuck all to do with ANYTHING other than eating too much.. because your hunger hormone is switched off by insulin resistance.
Therefore, when you stop taking the drug that regulates your blood sugar and suppresses appetite you WILL be hungry. The small amount of food that satisfied you with the GLP-1/GIP in your body will no longer satisfy you and your portions will increase.

There are of course exceptions to the rule and there are some people with the most extraordinary iron will - who may be able to maintain some of their loss but let me just give you the real life stats for the ‘eat less move more’ mantra.

A study of 275000 people in the uk and taken from primary care records and published in the BMJ in 2015 shows that only 8:1000 people are able to go from BMI 30-34 to less than >24. and of those stoic 8 , 6 will put it all back on and more within 5 years. Making the diet and exercise method of weight loss successful for only 0.02% of people trying to lose weight.

For me, I have made the decision to keep on a maintenance dose. I’m not a high earner and pay rent in the south-east, so it’s quite a commitment but I live alone and the food savings equate for at least 75% of the cost. So I’d rather think of the other 25% as an investment in my health and happiness. Not to mention the effort of selling a pile of size 22 clothes and replacing them with 8s …

i think people can understand stand it they just don’t want to as being fat is seen as a failure. It’s ingrained deep in our society to see fat people as lazy and having little self control or ambition.

I have lost 6 stones on MJ and the difference in how people especially men treat me is astounding. Eventually when all the hysteria and pearl clutching calms down I believe this medication will become as normal as blood pressure medication etc.

usedtobeaylis · 08/03/2026 14:07

I've been tapering off with 1.5 stone still to lose and it's very very hard already. I haven't been bingeing or anything like that but the hunger is intense at times. I deliberately under-dosed the whole time and lost 4.5 stone while overhauling my diet and exercise, with the hope that it was a more stable place retain control from. 5mg on the way up was incredible, on the way down it's not so effective. Ultimately over the year I created a calorie deficit that I will always struggle to maintain. I will HAVE to exercise to give myself leeway with that otherwise yep, it'll all go back on. That's not exclusive to WLIs - the deficit is hard to maintain for people who are used to eating more, whatever that reason was. Obesity and the effects of it are always there because weight loss is treating a symptom, it's not the end game.

Zanatdy · 08/03/2026 14:13

Its likely with any diet and everyone intends to have a buffer. I’m a yo-yo dieter and always will be as being 5ft I can’t eat much without gaining and you have to live too

tobee · 09/03/2026 00:01

I certainly find your posts helpful! It's great to hear from someone who has experience of long term maintenance with weight loss. I can also understand why you like to be part of these threads; you've mentioned you have to work hard at maintenence, and so being able to give and receive support here will be a valuable part of your on-going success, I would imagine. Well done!

Aww thankyou! I wasn’t planning on staying away from here but your post is really nice to hear! 😊 I just want to help and give realistic advice especially as people are starting to get to maintenance weights. I know how happy and confident I’ve felt since I lost it and want others to keep that feeling too, being obese is miserable but the body seems to want to go back to that constantly!

Fourwinds · 09/03/2026 20:34

Dr. Kevin Hall, a NIH researcher modelled that for every kg of body weight lost, appetite increases by 95 calories while expenditure decreases by 25 calories per day.

That's frightening.

Well done on losing the weight and maintaining, But your experiences aren’t really relevant to this board as you haven’t used WLI to lose the weight in the first place?

The majority of seriously obese people won’t ever lose weight by calorie counting and exercising alone! That’s why we’re on WLI.

Current medical thinking is that as a seriously obese person who has lost a lot of weight using WLI, you’ll need to titrate down and stay on a maintenance dose for up to 2 years after reaching your target weight to help retrain your brain and body into behaving differently to keep the weight off.

Going cold turkey from the injections and trying to calorie count/exercise won’t work for the majority of formerly obese WLI users and they will put the weight straight back on again. 🤷🏻‍♀️

Her experiences are relevant to this board if there are people reading who find them interesting and helpful. Not everyone will he planning on staying on wli long term, or titrating down for years. For posters like me, who plan to come off once at goal, reading about others' long term success at maintenance is certainly helpful and relevant, regardless of how the weight was lost in the first place.

Thanks! 🖤 and even people who stay on a maintenance dose have to work hard to keep calories down and exercise so it’s all relevant. It’s still restriction and resisting temptation, keeping up healthy habits. I think some people just don’t want any outsiders in here. But others might want to hear what it’s really like. (For people like yourself who plan to come off)

I really hate the phrase 'PILE it all back on'. It is so perjorative. Yes, after most diets there is some regain - faster or slower depending on what you are eating and how you are moving, and how you decide/manage to respond to an increase in weight - but that particular phrase seems to have been applied particularly to people who have taken WLI's. It feels like a continuation of fat shaming.

Anyway... I was on Mounjaro steadily for 10 months, managed to keep to lowish doses. Got to target weight in June. Maintained on the lowest dose for a couple of months, even dropped a couple more pounds. Since then I've been on the lowest dose at one month on, then one month off. Still at a steady weight.

The difference for me is that on previous diet regimes, I could stick to it for 3 or 4 months but then I was desperate for toast or pasta or a takeaway, or my regular wine habit. With WLI's I stuck to it (almost) effortlessly for 10 months. That gave me a good long time to re-evaluate my food and my exercise. My standard shopping list has completely changed. The variations I eat for breakfast have completely changed. The way I meal plan and shop has completely changed. Planning high protein, high fibre meals has become normal. Serving myself a small portion has become normal. Swerving a huge pudding has become normal (at least 90% of the time).

Plus I have been part of a really supportinve community here on mumsnet - not something than people in any of the clinical trials had!

Over the 18 months my blood sugar levels have stabilised - which they never did with other shoter dietary approaches. And that helps me to manage my feelings of hunger - which are less intense anyway. I think my stomach is used to smaller portions and I feel genuinely uncomfortable if I over-eat.

I am using a one month on / one month off approach so that I can gradually get used to the feelings of normal unmedicated hunger and to cement the lessons of how I manage my diet and lifestyle. By the summer I will probably move to a one month on and two months off. Hopefully while still remeining at a steady healthy weight. I feel an emotional and physical reassurance by still having the option to take WLIs for imtermittent periods. I helps me to be reassured that I can remain at this healthy weight, that I can adapt to a lifestyle where I'm eating only what I need. Maybe by summer 2027 I'll be doing it all on my own. We shall see.

But I don't belive I'd ever have got to (and stayed at) this healthy weight without WLIs.

The other thing to confide is muscle.

muscle is active, it burns calories even when at rest. Fat is inactive. So if you lose muscle during the weight loss phase and didn’t prioritise protecting it, it means your basic metabolic rate drops, which in turn means you can consume much fewer cals before you start gaining.

if you have ate your protein and strength trained you should be good. But body recomp is critical when you come off to rebuild anything you lost, drop any further excess fat. The more muscle you have the higher your bmr and the more you can consume before gaining. This is really Important, as if your muscle is low and you’ve lost a lot them maintaining without the meds will be nigh on impossible. It’s one of the many reasons people regain after dieting.

Just FYI the first part of this is nonsense - both fat cells and muscle cells use calories (glucose/glycogen) to create ATP and also use ATP to perform functions. So they both burn calories. Muscle cells just use MORE ATP (ATP is the body’s ‘energy’).

Edited

Well yes, but it is incredibly minimal and your bmr drops, so technically yes you are correct, the point remains.

here is an ai summary.

Yes, fat tissue burns calories at rest, but it is not metabolically active compared to muscle. While adipose tissue (fat) burns approximately 2–4.5 calories per pound daily, it mainly functions as storage, whereas muscle is much more efficient at burning energy.

Key Facts on Fat and Resting Calories:

  • Minimal Burn: Fat tissue burns very few calories compared to other tissues.
  • Muscle is More Efficient: Muscle tissue burns roughly 6–7 calories per pound daily—two to three times more than fat.
  • Higher Body Fat = Lower Metabolism: A higher percentage of body fat generally results in a lower resting metabolic rate (RMR).
  • Weight Loss Implications: Losing weight requires consuming fewer calories than you burn, as fat stores energy rather than actively consuming it.

This is still so new that everyone is still learning, we are all different and have different experiences before starting WLIs so there will be a mix, people will have different stories.

I do think though that if your daily calorie consumption on the medication is so low you wouldn't be able to maintain it long term then it makes sense that people would regain weight when they stop.

I am still titrating off (very slowly) but while I do that I am increasing my eating (reverse dieting), focusing on protein and fibre, while actively building muscle with a progressive overload - my aim is to build a body that needs at least 2000kcal a day to maintain because that feels sustainable to me. I know myself well enough to know I can't live life on only 1200 or even 1500 so I want some leeway. I was inspired by one of the female gladiators who said she needed thousands of calories per day - I don't want that to be my life but it made me aware there is a liveable middle ground. I have stopped my negative talk about that, I used to think myself weak willed but I now know it is a biological urge and I wouldn't beat myself up for not being able to hold my breath long enough to be a free diver.

I am loving how strong I am getting, and while I am staying the same weight I am actually getting leaner not bulky and body analysis scales are showing not only is my skeletal muscle increasing (and fat decreasing) my bones are improving too, which for a perimenopausal woman is fabulous. My skin is tightening up, I am even thinking about sleeveless tops when summer comes, for the first time in my adult life I have no jiggle.

In the past when I’ve lost a big chunk of weight it’s usually been through very low calorie (soups/shakes etc). When I’ve come off them I’ve regained quite quickly mostly because I’m beyond delighted at eating real food again. And when I have regained, I’ve felt utterly miserable at the thought of returning to powdery meals in a packet.

I’m hopeful that WLI is different anyway! At least I know if I tip back into ‘overweight’ I can stop it by going back on to WLI and catch myself before it becomes too big a problem again. It’s the only thing that’s ever given me hope that a slim and healthy life is actually possible.

I did those VLCD shakes for years on and off, spent thousands of pounds on them. I met hundreds of people doing the same and only 1 person I know of kept the weight off afterwards.

I did the daily then weekly jabs on and off for a couple of years. When there was a shortage I ended up putting the weight back on and was bigger than ever before with obesity related problems like gout and reflux. My BMI was 39. Then 2 years ago I had a private gastric bypass in the UK. My BMI is now 24.

For me I had to have something physical that stopped me over eating. With a bypass they say you are not to have more than 7g of sugar per 100g and that helps as a lot of my over eating was a sugar addiction.

MagicMJ · 10/03/2026 07:50

I want going to go back to my old habits. I wouldnt be one of those stats.

At one point I was on 15mg for a few months and lost 6 stone in total. I had titrated down to 2.5mg and then had to come off abruptly after Xmas due to money. In that time I have gained a stone and I believe its because if the abrupt end, I had always planned a methodical exit and old habits came in too fast because I had no plan ready. I always had the plan but no time to implement it.

So I look to get this stone back off and implement my true exit plan (v slow titration to microdose) with personal trainer muscle building and work out my maintenance cals/macros.

I dont want to be beholden to cal counting etc so it will be a rough guide or maybe if i cut back two days a week when creeping up.

Untailored · 10/03/2026 08:04

I think the reason it is tougher keeping it off when you’ve lost it through WLI is that many people haven’t made the mental shift. The drugs do that for you. So when you stop taking them, you have no protection against going back to your previous mindset.

There is no evidence to suggest it is tougher, in fact the evidence coming out now is people are keeping it off, because the drugs allow them to change fheir diets and make healthy choices.

dogrilla · 10/03/2026 08:26

I have never experienced hunger like the hunger I had after coming off MJ - and that was even after tapering off the dose for weeks at the end. I absolutely ballooned. Obviously not the same for everyone

Totally agree! When people say things like that, it’s almost like they’re wishing for that to happen. Can’t they just be happy that right now I’m losing weight and getting healthier, rather than telling me there’s no point in even trying?

Over the years, I’ve lost and regained more stones than I would be able to count. All the family on my mum’s side have weight problems in varying degrees and weight is something I know I will always struggle with. One of my relatives is 35+ stone and seeing him recently, really motivated me to finish the job properly. He’s so unhappy and likely trapped in a food addiction. He’s been on Wegovy but has managed to eat through it and is in denial. Ever since the age of 11, I’ve been aware of weight gain and post MJ, it’ll continue to be a struggle. I just wish some people could be happy for me right now instead of suggesting there’s no point. 😌
