Food Noise: What It Is, What the Science Says and What GLP-1 Drugs Do

“Food noise” is the popular name for thoughts about food that won’t switch off: what you’ll eat, when, whether you should, and around again. It isn’t a diagnosis. According to a 2023 review, it’s a colloquial term that grew out of what patients and clinicians described: on GLP-1 medications, many people said the noise went quiet, something that still needed systematic study^[1]. Since 2025 there are formal definitions and a validated questionnaire^[2,3], but I haven’t yet found a placebo-controlled trial that measures it with that questionnaire.

If what you feel is physical hunger, see always hungry: causes and what helps; if it’s on a GLP-1, see still hungry on Ozempic or Mounjaro. If it’s specifically sweets, see sweet cravings on GLP-1s.

What is food noise?

The phrase wasn’t born in a lab, but since 2023 it has working definitions:

All three agree on the basics: it isn’t thinking about food, which is normal, but those thoughts persisting, bothering you and being hard to push aside. The 2025 panel compares it to rumination, repetitive thinking that crowds out other mental activity^[2].

A note on funding: the FNQ questionnaire has four authors who are employees or shareholders of WW International (Weight Watchers)^[3]. The 2025 panel was funded by the company Ro, and two of its authors report ties to Novo Nordisk or Eli Lilly^[2]. That doesn’t invalidate the work, but it’s worth knowing.

Is constantly thinking about food common?

The first population figure I’ve found came in 2026. Hayashi and Masterson asked 1,000 US adults, in a sample weighted to represent the population, how often they experience “food noise”, described to them as “constantly thinking about food, even when not hungry”^[4]:

• 50.9% said at least sometimes, and 18.0% often or always.
• It was more common in women (22.7% vs. 12.7% in men) and in adults under 30 (26.5%).
• The strongest link, also after adjusting for other factors, was loss of control over eating: among those who reported it, 56.8% had food noise often or always.
• It was also more common among current GLP-1 users (25.8%) than among non-users (16.3%).

It’s a single question, not a validated scale, asked at one point in time, so it can’t show what causes what. More food noise among GLP-1 users doesn’t mean the drug causes it: the authors think it more likely that the people who struggle most with it are the ones who seek or get treatment^[4].

How it overlaps with what science already measured

The name is new, but it overlaps with ideas researchers have studied for years. I explain the difference between hunger, cravings and food noise in still hungry on a GLP-1; here’s how each one is measured:

The overlap is large. When the FNQ was validated in 396 adults, its score correlated at 0.87 with the preoccupation-with-food subscale of the FCQ-T and at 0.79 with a food preoccupation questionnaire^[3]. A correlation of 1 would mean measuring exactly the same thing. The authors themselves acknowledge that five items may miss other aspects of the concept^[3].

My take: food noise isn’t made up, but much of what’s said about it comes from studies that measured cravings, food preoccupation or control of eating under other names.

What GLP-1 drugs do to food noise

What the labels say

No label uses the words “food noise”. The closest they get is what they say about appetite and cravings, and the US and EU labels don’t say the same thing.

• Wegovy and Zepbound (US). Section 12.1 of the Wegovy label says GLP-1 is a physiological regulator of appetite and caloric intake, and the GLP-1 receptor is present in several areas of the brain involved in appetite regulation. Section 12.2 of both the Wegovy label and the Zepbound label says the drug decreases calorie intake, and the effects are likely mediated by affecting appetite^[8,9]. The US labels don’t mention cravings.Dotted underline: a drug-label fact; hover over it to see the date it was checked.
• Wegovy (EU). The EU prescribing information says semaglutide may affect the hedonic reward system through direct and indirect effects in brain areas including the septum, thalamus and amygdala, and that in clinical studies it reduces feelings of hunger and the frequency and intensity of cravings, and reduces the preference for high-fat foods^[10].
• Mounjaro (EU). The EU prescribing information for tirzepatide, the same drug as Zepbound, says it reduces the intensity of food cravings and preferences for high-sugar and high-fat foods^[11].

These are average effects compared with placebo, not a promise for any one person.

What the trials measured

Tronieri’s trial comes closest to the concept, and its nuance matters: by one year the difference had faded, even though the liraglutide group had lost more weight (11.8% vs. 6.2%)^[14]. Liraglutide is an older GLP-1; I don’t know whether the same happens with semaglutide or tirzepatide.

The 2025 joint advisory on nutrition and GLP-1 therapy, from four US medical and nutrition societies, notes that several studies show reduced food preoccupation or “food noise”, less emotional eating and fewer binge episodes^[16]. Its authors add that in practice they see many people become less interested in food and ruminate about it less^[16].

The only data using the food noise questionnaire

In the INFORM survey, 550 US adults using semaglutide for weight management, 86% of them women, filled in the FNQ twice: recalling how things were before and how they are now. The median score fell from 13 to 6 out of 20^[15]. But it relies on memory, has no comparison group, drew on a consumer panel and was commissioned by the manufacturer, Novo Nordisk^[15]. It’s good for raising the question, not for answering it.

What happens when you stop

I haven’t found studies that measure food noise after stopping a GLP-1. Withdrawal trials measure weight:

• STEP 1 extension (summary). In the subgroup followed after the trial, people who had lost an average of 17.3% on semaglutide regained 11.6 percentage points in the year after stopping, about two-thirds of what they had lost^[17].
• SURMOUNT-4 (summary). After 36 weeks on tirzepatide, those switched to placebo gained 14.0% over 52 weeks; those who continued lost another 5.5%^[18].

My assumption is that if appetite and cravings return, food noise does too, but that’s my inference, not a measured result. Why appetite comes back and what’s linked to regaining less weight is in stopping a GLP-1 and weight regain. Whether and how to stop is a decision to make with your doctor.

What helps without medication (and what isn’t proven)

No study has tested any strategy against food noise measured with the FNQ. What follows are habits with some support for hunger or cravings, which make sense as a foundation.

Regular meals, no long gaps

The 2025 advisory encourages regular, small meals at consistent times and recommends minimizing long periods without meals that leave you overly hungry^[16]. On a GLP-1 this matters more: the same advisory warns that low interest in food can lead people to go several hours without eating^[16].

Enough sleep

In a 2004 trial with 12 healthy young men, two short nights raised hunger by 24% and appetite for calorie-dense, high-carbohydrate foods by 33% to 45%^[19]. The 2025 advisory links poor sleep to increased hunger^[16]. More in sleep, stress and appetite.

Enough protein

The 2025 advisory makes adequate protein a priority for people on these drugs, mainly to preserve muscle^[16]. There’s no evidence that protein quiets food noise; I include it as part of eating enough. You can estimate your number with the protein calculator and read more in protein and muscle on GLP-1s.

Stress, mindfulness and therapy

The 2025 advisory suggests that referral for cognitive behavioral therapy or mindfulness-based stress reduction may be considered when stress is a factor^[16]. For food cravings, a 2025 meta-analysis of 24 controlled studies with 1,920 adults found that mindfulness-based interventions modestly reduce how intense cravings are, but not how often they happen. The certainty of the evidence is low^[20].

Fewer food cues in sight

If food noise is, as Hayashi proposes, a form of food cue reactivity^[1], it makes sense to reduce those cues: the bag of nuts off your desk, the sweets in a cupboard instead of on the counter. That’s a practical idea of mine, not something tested in food noise studies.

To see when it shows up, log it for a few days in the symptom diary: the time, what you were doing, how long since you’d eaten and how you slept.

When food noise is something more

Thinking about food a lot isn’t a disorder, but loss of control over eating is the factor most strongly linked to frequent food noise^[4]. According to MedlinePlus, in binge eating disorder a person regularly eats unusually large amounts of food and feels a loss of control. Among the things that may lead to it, MedlinePlus lists unhealthy dieting, such as skipping meals or not eating enough nutritious food. It’s treatable, with psychological and nutrition counseling^[21].

The 2025 advisory calls for screening for eating disorders before starting a GLP-1. It acknowledges that the effects of these drugs on eating disorders aren’t well established and could, in theory, ease or worsen symptoms^[16].

The goal is to eat well and calmly, not to eat as little as possible.

Frequently asked questions

What is food noise?

An informal term, not a diagnosis, for thoughts about food that won’t switch off^[1]. Under the 2025 definition, they’re persistent and the person finds them unwanted or distressing^[2]. It’s measured with a five-item questionnaire, the FNQ^[3].

Why am I constantly thinking about food?

Food noise studies haven’t untangled the causes yet. In related research, short sleep raised hunger in a small trial^[19], and long gaps without meals leave you overly hungry^[16]. If it comes with binges or loss of control, it’s worth seeing a professional^[21].

Does Ozempic get rid of food noise?

No placebo-controlled trial has measured it with the FNQ. The EU label for Wegovy, the same semaglutide as Ozempic, reports fewer and less intense cravings^[10], and the only direct measurement is a retrospective survey commissioned by the manufacturer^[15]. It points to an average drop, without saying how much or for whom.

Does food noise come back after stopping Zepbound or Ozempic?

No one has measured it. Weight has been: in SURMOUNT-4, people who stopped tirzepatide gained an average of 14.0% over 52 weeks^[18], and after stopping semaglutide, about two-thirds of the lost weight came back within a year^[17]. My assumption is that if appetite returns, some of the noise does too.

How do you quiet food noise without medication?

No method has been proven against food noise itself. For hunger or cravings, there’s some support for regular meals^[16], enough sleep^[19] and, with low certainty, mindfulness for craving intensity^[20]. If it distresses you or you lose control around food, get professional help^[21].
