The 30-second summary
- A survey of 1,000 US adults, published on 26 September 2026 in Obesity Science and Practice by researchers at Penn State, measured how many people say they experience food noise.
- About half said at least sometimes. 17.98% said often or always.
- Among people currently taking a GLP-1 such as Ozempic, Wegovy or Mounjaro, 25.76% reported frequent food noise, against 16.30% of non-users.
- The authors think that gap reflects who gets prescribed these drugs, not a drug effect. The survey cannot tell the two apart.
What is food noise, and why measure it?
Food noise is a lay term, not a diagnosis. It describes constant, intrusive thoughts about food, even when you are not hungry. The phrase took off in 2023 alongside GLP-1 medicines, because many people taking them described the noise going quiet.
Until now nobody had measured how many people would say they have it. Researchers in the Department of Nutritional Sciences at Penn State added one question to a national survey run by Verasight in May 2026. It described food noise the way the media does, as constantly thinking about food even when not hungry, or feeling that life revolves around food, and asked how often people experience it, from never to always.
The results were weighted to match the US adult population on age, sex, ethnicity, income, education and region.
What did the survey find?
| Group | Food noise often or always |
|---|---|
| All adults | 17.98% |
| Women | 22.70% |
| Men | 12.68% |
| Aged 18 to 29 | 26.50% |
| Aged 60 and over | 13.49% |
| Not on a GLP-1 in the past year | 16.30% |
| Current GLP-1 users | 25.76% |
| Former GLP-1 users | 26.78% |
| Reporting loss of control over eating | 56.77% |
People with frequent food noise also rated their own eating lower and reported poorer mental health.
After adjusting for everything else, the strongest predictor by far was loss of control over eating, with an odds ratio of 5.95. The authors name current GLP-1 use (odds ratio 1.60, 95% confidence interval 1.08 to 2.37) and being a woman (1.47) as the other leading predictors. Eating less to change weight or shape was also linked (1.57). Former GLP-1 use was not a significant predictor once other factors were accounted for.
Does this mean GLP-1 medicines cause food noise?
No. This is the part most likely to be misread.
The survey asked everyone once. It has no "before" for the GLP-1 users, so it cannot show whether their food noise went up, down or stayed the same after starting. The 124 current users were simply compared with people who had not taken one.
The authors offer a simpler explanation: selection. Obesity and insulin resistance are linked to stronger reactions to food cues, and those are exactly the conditions these medicines are prescribed for. So people on a GLP-1 may start with more food noise than average. Even if the drug turns it down, it may not bring it below the level of someone who never had much.
That fits what users themselves describe. Our guide to food noise and GLP-1 medicines covers why the drugs quiet it for many people.
What are the limits?
- One question, not a validated scale. It measures whether people identify with the term, not how severe their thoughts about food are.
- A snapshot. Cause and effect cannot be read from it.
- Small subgroups. 124 current and 53 former GLP-1 users.
- Self-report. GLP-1 use, eating behaviour and health were all reported by participants.
- Many tests. The authors did not correct for multiple comparisons and describe the findings as hypothesis-generating.
What does it mean if you take a GLP-1?
If food noise has not gone fully quiet on your medicine, you are not unusual. In this survey, about 1 in 4 current users said they hear it often or always. It is not a sign that the drug has failed, and it may say more about where you started than where you are.
Food noise can also return later in treatment. Food noise coming back covers why that happens and what helps.
Three things tend to make it quieter, whatever the cause:
- Regular meals, not long gaps. Long stretches without food give the noise room. Three planned meals, with a snack if you need one, take decisions off the table.
- Protein and fibre at each meal. Both keep you full for longer, which matters when the medicine is doing less of that work. If you often still feel hungry on a GLP-1, start here.
- Decide food before you are hungry. Knowing what dinner is removes a lot of the background thinking.
The survey's strongest link was with loss of control over eating. If you often feel you cannot stop eating once you start, or food thoughts are crowding out the rest of your day, tell your prescriber. That deserves a proper conversation, not a stronger plan.
