Trying on clothes for a summer holiday in Greece, I sifted through what still fitted after a year of struggling with my weight – and what didn’t. All the time there was the nagging thought that the solution to the problem was sitting in my fridge in the form of weight-loss jabs.I could just go downstairs, start jabbing and in a few weeks I’d be able to fit into my entire wardrobe.As someone who was anorexic from the age of 15 to 24, weighing as little as 6st, this wasn’t just a passing thought but a realisation that threatened to destabilise my recovery entirely.In fact, I liken the GLP-1 pens being in my home to an alcoholic keeping a chilled bottle of wine in their fridge. It makes me feel everything from panicked to terrifyingly vulnerable. So why keep something so triggering so close? The answer is that they are not mine, they belong to my husband David, who, despite my protests, continues to use Mounjaro regardless of this effect on me.I’ve always been against these drugs when used for non-medical purposes. I believe they will end up creating a whole new generation of people with eating disorders. If the likes of Mounjaro had existed when my eating disorder was at its worst, I’d have done anything to get my hands on them and I believe that, ultimately, they would have killed me. It upsets me just to think of it.And yet this didn’t deter David from taking them; at first, he just did so secretly.Now 49, he has lost three stone in under two years and some would say he looks all the better for it. With his olive skin and dark hair, he’s always been handsome but now his biceps are honed, his legs lean, and his jaw chiselled. Many think Alice's husband David, who has lost three stone since using Mounjaro, looks better than ever, but she says she has never found him less attractiveThat said, in our 12 years together, I’ve never found him less appealing. But for our four-year-old son, I would seriously consider divorcing him.In the process of going from 14st 7lb to 11st 4lb, my 5ft 11 husband has lost far more than pounds on the scale.Gone is his libido – while he never had a huge sexual appetite, our intimate life has been non-existent for 18 months, an early casualty of his new regime.His joie de vivre, too, has become completely subsumed in his obsessive quest to lose weight. Previously kind and affectionate, David is now highly strung and controlling. The easy-going guy who cooked his family fabulous meals has become unappealingly militaristic in his attitude to his health.But more to the point, I’m disappointed by his lack of concern for the effect that the presence of Mounjaro is having on me.When I dared to broach the subject of how much distress the jabs were causing me – in the context of my historical eating disorder - he said simply, ‘Well, I’m not going to stop taking them.’ That was it. End of conversation.Yet the jabs have almost certainly triggered an eating disorder in him. He had previously struggled with emotional eating from time to time – if he was stressed, for example – but since taking the jabs he now makes himself sick if he inadvertently eats too much the night before.And I say that as someone who knows what an eating disorder looks like. After my mother’s second marriage began to deteriorate, she took her sadness out on me and that, coupled with the stress of trying to juggle A-levels, a swathe of extra-curricular activities and a part-time job, caused my own anorexia.I was 17 when I was diagnosed with the condition after dropping from a healthy 8st 7lb to 6st. But treatment wasn’t forthcoming and I received just a handful of counselling sessions from the NHS, which did little to help.It was only when I went away to university and was detached from my mother and all the other stresses that I slowly realised how miserable and restrictive my life had become. Over the coming years, I gradually steered myself out of my eating disorder. By the time I met David on a dating app 12 years ago, when I was 34 and he was 37, I’d been eating normally for a decade. The main point of contention? Alice is disappointed by David's lack of concern for the effect that the presence of his weight-loss jabs have on her, as someone with a history of anorexiaBoth of us were ready to settle down, but also had the same spirit of fun – we loved to travel, and adored eating out in London where we both worked, me in marketing, while David owned an insurance company.David was so handsome, and I liked his easy manner – he never obsessed over anything. He went to the gym, but would also devour the bread basket with me when we went out to eat.He loved to cook and made some of the best curries and south American meals I’ve ever tasted. His skills in the kitchen made me feel cherished.We married in September 2019 and over the next year, he gained a stone, mostly due to lockdown when he cooked more and gyms were closed. It wouldn’t have mattered to me if he’d never lost a gram of it. I thought he was gorgeous.Gradually, though, it started to bother him. He was never fat but he spoke wistfully of the slender frame he’d had in his 20s and early 30s.The turning point was when he sold his insurance business for a seven-figure sum in late 2022. Without it, no longer a CEO with clout in the insurance world, he suffered a real identity crisis. He also had time on his hands to ruminate over his waistline.In hindsight, I can see these were all the ingredients for his midlife Mounjaro crisis.Just after he turned 46 in April 2023, he started doing bootcamp style fitness classes with friends. Then he rejoined a gym, hired a personal trainer and became hellbent on shaping up.I was supportive as we’d had our son in 2021 when I was 41 and I loved the idea of David being as fit as possible to run around with him.Then, just over two years ago, the headlines were filled with stories of people who, like David, weren’t clinically obese, but had started using fat jabs to shift a stone or two. I so vividly remember discussing these jabs with David at the time. When I told him how strongly opposed I was to their use for non-clinically necessary weight loss, David shut me down and left the room.Little did I know he was already considering taking the drug himself.A few months later in summer 2024, the postman rang the doorbell and asked me to sign for a parcel for David. I later saw the discarded box in the bin and was horrified to look at the delivery note and discover it had contained weight-loss pens.The old David would never have dreamed of doing something he knew would be so hurtful to me. But when I confronted him, he was positively nonchalant. He’d been using them for a month, he admitted, and hiding the pens in a fridge in his study. Now David will only eat specific foods – micro portions and bland ingredients. He is secretive about his meals too, eating at irregular times rather than dining with his familyI was hurt that he hadn’t discussed this with me. Once out in the open, though, he was all too happy to complain about the resulting headaches, stomach cramps, nausea, acid reflux and dizziness.Meanwhile, my mind whirred in a way it hadn’t since I had been in the throes of my eating disorder. Did David think I should be on Mounjaro too? Would he prefer me slimmer?While I’m not overweight by medical standards, I hadn’t got my figure back after giving birth. I was sure David would be all too happy for me to start jabbing, too.After all, he wasn’t seriously overweight either. No reputable doctor would ever have prescribed him Mounjaro – his BMI was just 25 so he was using an online clinic, inputting fake information about his weight and height in order to score his next hit.It has taken him just under two years to lose the weight he wanted. Meanwhile, the whole fabric of our family life has changed. David will now only eat specific food orders from a food delivery service specialising in ‘Mounjaro meals’ – micro portions, bland ingredients.He will also only eat irregularly, at odd times – it could be 8am, or midnight, depending on how the jab works its way through his system and the hunger kicks in. He won’t cook or sit to eat with us like he used to and is so secretive about his meals that there are days when I don’t know if he’s eaten at all.Where once we had an active social life – hosting dinner parties and popping to interesting new restaurants near our London home – now there is only a blank calendar and a silence around our kitchen table.Life with David is joyless. It’s like Mounjaro hasn’t just taken away his desire for food, but his desire for life, too.Nothing will get in the way of David’s need for the drug. Not the death of our previously satisfying sex life. Not the loss of our friendship circle. Nor the fact that his weight-loss obsession has brought back all my anxieties and insecurities around food.My once lively and sociable spouse seemingly has no understanding of how selfish his new habit is, and how much of a toll it is taking on me and our family. So here we are, a few weeks away from our ninth wedding anniversary and teetering dangerously close to divorce.When I try to tell him how I don’t care what he looks like, and how I feel I’ve lost my previously thoughtful husband, he stands and listens. But he flatly refuses to alter his behaviour or acknowledge the dreadful state of our marriage.If I bring up the fact that he’s never physically affectionate any more, and doesn’t even attempt to initiate sex and refuses when I do, he just shrugs his shoulders. We don’t even sleep in the same bed any more.Some might think his new obsession with his appearance is a sure sign he is being unfaithful, but I genuinely don’t think so. He works from home now, rarely goes out – and, as I said, has never had much of a libido.Thankfully, he remains a terrific dad and dotes on our son. But in some ways this only pains me more, as he has no cuddles or kind words for me.While he laps up the many compliments he gets about his new physique, and his confidence is seemingly sky high, I mourn the man he once was and the marriage we once had.Divorce is something I think about a lot, imagining how much lighter I’d feel if only I could walk away from my husband and his fridge full of Mounjaro.But working part-time since having our son and the fact we keep our money separate – even though he made a fortune selling his company – means that, realistically, I don’t have the personal means to escape, nor the heart to break up our little family.Then again, by making fat jabs the third party in our marriage, David has already shattered our relationship.Alice Jarvis-Jones is a pseudonym.
