GLP-1s and Binge Eating ~ What You Need to Know

GLP-1s and Binge Eating ~ What You Need to Know

GLP-1 medications, such as Ozempic, Wegovy and Mounjaro, have gone from diabetes treatment to cultural phenomenon in a remarkably short time. And one of the questions I’m hearing more and more, both in clinic and in the wider conversation, is what they mean for binge eating. Could they help? Could they make things worse?

The honest answer is that both can be true, depending on the person - which is exactly why it’s worth slowing down and looking at what we know so far and what’s showing up in practice.

I want to be upfront and clear about saying I’m not against these medications. They have a real place in medicine and a few of my clients use them or have tried them. But when it comes to eating disorders, and binge eating in particular, there’s a lot more to think through than the headlines suggest. I wrote about what happens when people come off these drugs back in early 2025 (see the blog here), and a great deal has moved on since then.

(I’m a nutrition practitioner, not a doctor, so nothing here is advice about whether to start or stop a prescribed medication - that’s a conversation to have with your GP or prescriber.)

Popularity and pressure

Part of what makes the topic of GLP-1s so charged is the context behind it and the pace of uptake in the UK and across the world.

These medications arrived into a culture that already treats weight loss as a moral good and a smaller body as a personal achievement. Before-and-after posts, celebrity speculation and a steady drip-feed of “everyone’s on it” have made them feel less like a medical treatment and more like the latest route to the body we’ve all been told we should have.

At the same time, NHS access has stayed tightly limited while a private online market has grown quickly to fill the gap. For many people, getting a prescription now involves a questionnaire and a payment rather than a personal conversation with someone who has their full health history.

This matters a great deal for anyone whose relationship with food is already complicated and it’s a big part of why eating disorder specialists have become increasingly concerned.

And it isn’t only people taking these medications who are affected. For anyone in recovery from an eating disorder, or whose relationship with food feels fragile, both the adverts and the casual but constant conversation around weight loss injections can be hard to escape.

This all subtly (or perhaps not so subtly these days) reinforces the idea that a smaller body is something we should all be aspiring to and that appetite is something to be suppressed. For some people, the exposure to this noise around GLP-1s alone can be enough to stir up old thoughts and behaviours or make recovery feel harder to hold on to.

Can taking GLP-1s trigger eating difficulties?

This is a real area for concern. Simplistically speaking, these medications suppress appetite and make eating less feel easier, so for someone vulnerable to disordered eating, it’s very easy to see how that can tip into something harmful.

One large analysis of medical records found that just over 1% of people starting a GLP-1 were diagnosed with an eating disorder within two years - mostly anorexia, rather than binge eating. The risk was more than doubled in people who already had a mental health condition. A perspective in the New England Journal of Medicine warned that the medical system is unprepared for what may be coming.

But at this time, the evidence is still thin. The study didn’t compare people taking GLP-1s with people who weren’t so it can’t tell us whether the medications caused those diagnoses or whether the people affected were already at risk. But what we can say is that the concern is serious enough that clinicians across the field are now calling for screening - more on that below.

And what about coming off them?

Again, the risk is real. The clearest evidence we have comes from a follow-up of one of the major semaglutide trials: a year after stopping, people had regained around two-thirds of the weight they had lost and appetite tended to return strongly. For someone with a history of binge eating, that return of hunger can collide with everything that was left unaddressed while the medication was doing the work - and the old pattern can come back, sometimes harder than before.

I’ll speak only in general terms here out of respect for the people I work with, but I have supported people who turned to these medications hoping for relief from a difficult relationship with food, only to find an old eating disorder reignited after stopping them.

It appears these are not rare stories - in their blog, the UK eating disorder charity First Steps ED has described similar experiences among the people it supports, including in people who obtained the drugs online with little or no assessment.

But it isn’t only people with a history who are at risk. Add the distress of weight regain and the urge to diet again, and the conditions are there for a restrict-binge cycle to start, even for someone who has never struggled with food before.

Can GLP-1s stop binge eating? The evidence for help and harm

This is a potentially polarising question and worth understanding more about, particularly as GLP-1s are increasingly being discussed as a possible treatment for binge eating, even though they aren’t currently licensed for it.

A large review published this year pooled 25 trials and more than 8,000 people and found that GLP-1 medications reduced binge eating episodes, loss-of-control eating and emotional eating - at least in the shorter term. For someone whose days have been dominated by food noise and the urge to binge, that kind of ‘quiet’ can feel like an enormous relief and I’d never dismiss that.

But as is so often the case with research, the devil is in the detail. Most of the trials were funded by pharmaceutical companies and carried a high risk of bias. Very few included people with a diagnosis of binge eating disorder. And follow-up was mostly short so we don’t yet know whether the benefits last.

There’s also something in that review that I find telling. Alongside less bingeing, people reported more dietary restraint and the researchers themselves said they couldn’t tell whether that was healthy self-regulation or something more worrying.

This question sits right at the heart of my work as binge eating is half of a cycle that very often begins with restriction - whether that’s dieting, skipping meals, rigid rules or simply not eating enough across a demanding day. The body responds to being under-fed by ramping up the drive to eat and eventually that drive to eat wins.

So a medication that works partly by suppressing appetite and increasing restraint can quieten the bingeing while leaving the engine that powers it running underneath. The behaviour goes quiet, but the reasons it was there - the restriction, the rules, challenges with emotions and the job food was doing - remain. And if food has been someone’s main way of coping, suppressing it without offering anything in its place can leave them more exposed, not less. ‘Quietening’ something is not the same as healing it.

What needs to change

If these medications are going to be prescribed as widely as they now are, a few things seem to me to be essential.

The first is the access problem in the private market. A 2025 ITV investigation found that most of the eating disorder clinics it contacted had treated patients who had obtained these drugs online. A BBC undercover investigation the same year found online pharmacies allowing people to falsify their health details.

The pharmacy regulator has since tightened the rules, requiring independent verification of weight for remote prescribing rather than relying on what people say about themselves. This is a step forward but it will only make a real difference if it’s enforced.

Closely related to this is screening. There is growing agreement across the field that anyone being considered for a GLP-1 should be asked about current and past eating difficulties, binge eating and body image concerns before they’re prescribed - and monitored afterwards. A few simple, validated questions could make a real difference to people who are currently slipping through. I think if you’re considering this route, it is entirely reasonable to expect that conversation.

At the moment, the standard advice is that these medications should be used alongside a reduced-calorie diet and more physical activity. For most people that may be ‘reasonable’. But for someone with a history of binge eating, more restriction is exactly what keeps the cycle turning.

That’s why I believe that when someone with a history of eating difficulties does go ahead with a GLP-1, support from an eating disorder-informed professional for their relationship with food and nutrition, should be offered as standard - and not left to chance.

There have also been calls, including from UK eating disorder charities, for tighter restrictions on how these medications are advertised, particularly on social media.

If you’re considering a GLP-1 or already taking one

If you’re weighing up whether to take a GLP-1, I’d encourage you to think seriously about your own history with food. If you’ve struggled with binge eating, restriction or a long cycle of dieting, it is worth talking that through honestly with your prescriber before you make a decision.

And if you’re hoping a GLP-1 might help you stop binge eating, it’s worth thinking about what support you might need alongside it - to work on your relationship with food and the factors that triggered the bingeing and keep it going. That way, if and when the medication stops, you’re in a different place psychologically and emotionally as well as physically, and better placed to cope with the likely return of appetite.

And if you’re already taking one, please don’t read any of this as judgement. You will have had good reasons for your decision. Again, being on a GLP-1 and doing the deeper work with food are not mutually exclusive. In fact, the quieter period the medication creates can be a real opportunity - a window to rebuild steadier eating and start to understand the patterns underneath, so that there’s something solid holding you when the medication comes to an end.

Finally, if you have a difficult relationship with food and experience binge eating or binge eating disorder, also know that there is another path that doesn’t depend on a medication.

It involves building a steady foundation of nourishment, letting go of the mindset and rules that keep the cycle turning, finding new ways to support your emotional resilience, and slowly rebuilding trust with food and your body. Yes, it is slower work. But it is work that holds and gives people back the time and energy that food has been taking from them.

Whichever path feels right for you, you don’t have to work things out alone. I offer nutrition support for binge eating with or without medication, including during and after GLP-1 use. You are welcome to book a free enquiry call to talk things through.
