Food noise, binge eating, and the question nobody asks you

Food noise was not a clinical term. Patients invented it, and the profession adopted it afterwards, which is a direction of travel so rare it is worth stopping on.

What it describes is a more or less continuous background preoccupation with food. Not hunger, which has a cause and an answer. Not craving a particular thing, which is specific and passes. A running internal commentary — what is in the kitchen, what is being planned for later, what was left, what could be got on the way home — that does not stop when a meal ends and does not correspond to needing to eat.

It spread between patients, then through online communities, then into appointments because people kept using it there, and eventually into published work where researchers have been trying to define and measure it properly.

Two things about that are worth sitting with. The first is that before it had a name, it could not be recorded. It was not that clinicians dismissed it; there was no slot for it in a history, and a thing that is not asked about does not get written down. The second is what happened when patients began treatment with these medicines. A striking number described the noise stopping, and described that — rather than the weight — as the change that mattered most to them. Trials were measuring kilograms. Patients were reporting something the outcome measures had not been built to capture.

That is a real finding and it deserves saying plainly. It is also where the honest version of this post diverges sharply from the convenient one.

Here is the reasoning you will meet constantly, usually from somebody with something to sell.

These medicines quiet food noise. Binge eating disorder involves a loss of control over eating. Therefore these medicines treat binge eating disorder.

Every statement in that chain is defensible except the one that matters. The conclusion does not follow, and acting on it as though it did is how people get hurt.

A treatment that reduces how much someone eats is not thereby a treatment for a disorder of eating. Binge eating disorder is not a quantity problem with a quantity solution. It is characterised by recurrent episodes of eating unusually large amounts with a sense of loss of control, followed by distress, shame and secrecy — and the distress, the shame and the secrecy are not side effects of the eating. They are the condition. Reduce the eating without touching them and the condition is not treated. It is concealed, including from the person who has it.

There is a specific mechanism of harm here, not merely a theoretical objection. Restriction is a known trigger for binge episodes. A medicine that makes eating less feel effortless can produce a period of unusually successful restriction, followed — particularly if the medicine is stopped, or a dose is missed, or appetite returns — by exactly the conditions under which the cycle reasserts itself, now with the added weight of having apparently solved it and then failed. That is a worse place to be than the starting point.

This is the section to take to an appointment, because it is short and it is checkable.

No weight-management medicine holds a licence to treat binge eating disorder. Not in the UK, not in the EU. The licences cover weight management in adults above defined BMI thresholds, and that is the whole of it.

In the United Kingdom the recommended first-line treatment for binge eating disorder is psychological. A binge-eating-disorder-focused guided self-help programme first, and where that is unsuitable, declined, or has not helped after a few weeks, a course of cognitive behavioural therapy adapted for eating disorders. That is the pathway, and it has an evidence base behind it that no medicine in this category has for this condition.

There is a medicine licensed for binge eating disorder — in the United States. Lisdexamfetamine was approved there for moderate to severe binge eating disorder in adults in 2015. In the UK the same molecule is licensed for attention deficit hyperactivity disorder: the Elvanse Adult label names ADHD and names nothing else. So a British reader who finds American material about a drug treatment for binge eating is reading about a licence that does not exist here.

Which leaves a genuinely awkward position, and pretending otherwise would be dishonest. Binge eating disorder is, by some distance, the most common eating disorder. It is substantially under-diagnosed. The psychological treatment that works is not always available quickly. And the medicines that are available quickly are licensed for something else. That gap is real, and it is the gap into which bad advice flows.

People conceal an eating disorder history at assessment because they expect it to be used against them. It is the single most understandable omission in this whole process, and it is a mistake — not morally, but tactically.

A history of binge eating disorder is not an automatic exclusion from weight-management treatment. It is a reason for the plan to be different: for the monitoring to be closer, for psychological support to run alongside rather than afterwards, for the stopping conversation to happen at the start, and for someone to be watching for the signs that restriction is going somewhere it should not. None of that can be arranged for a history that nobody knows about.

The version where it is concealed is the version where you get the medicine and none of the scaffolding. That is the worst available outcome and it is the one secrecy produces.

It is also worth knowing that a careful assessment should be asking. Screening for disordered eating before starting a weight-management medicine is good practice, and a service that never raises it is telling you something about how thorough the rest of its assessment is. If nobody asks, you can say it anyway.

One word gets used for all of it, which is part of why people cannot describe what is happening to them.

Homeostatic hunger is the body asking for energy. It builds, it has a physical character, and a meal answers it.

Food noise is preoccupation. It does not build toward anything and a meal does not answer it, because it was never a question about energy. It is exhausting in a way that is hard to convey to someone who has never had it, precisely because nothing visible is happening.

A binge episode is distinct from both: a discrete period of eating an amount most people would regard as unusually large, accompanied by a sense that it cannot be stopped, and followed by distress. The loss of control is the defining feature, not the quantity.

Why the distinction is practical rather than semantic: the three have different answers. Hunger is answered by food. Food noise may be reduced by treatment, and for many people is. A binge pattern needs a psychological treatment, and reducing appetite does not substitute for it. Someone who cannot tell a prescriber which of the three they are describing will usually be treated for the wrong one, and the vocabulary for the middle term only exists because patients built it.

If you are not sure which you have, that uncertainty is itself worth saying out loud. It is a better opening than a guess.
