Adding a GLP-1 to a behavioral weight program cut food noise more than behavioral treatment alone

Adults who started a GLP-1 medication while enrolled in a digital behavioral weight-management program reported a bigger drop in "food noise" after one month than adults who did the program alone, according to research presented May 13, 2026 at the European Congress on Obesity in Istanbul, Turkey ^[1].

The work is an observational cohort study led by Dr. Hanim Diktas, a postdoctoral researcher at LSU's Pennington Biomedical Research Center in Baton Rouge, Louisiana, and colleagues ^[1]. It followed 417 adults. Food noise was defined in the study as persistent, intrusive thoughts about food that disrupt daily life and make healthy behaviors difficult ^[1].

Participants answered the Food Noise Questionnaire (FNQ), which asks five statements — such as "I find myself constantly thinking about food throughout the day" and "My thoughts about food feel uncontrollable" — each rated from 0 to 4, for a maximum score of 20 ^[1]. Scores were collected at the start and again one month later, along with body weight measured on digital scales ^[1].

Of the 417 participants, 92 started a GLP-1 receptor agonist alongside behavioral treatment in a program called Weight Watchers Med+, and 325 received behavioral treatment alone in Weight Watchers Core+ ^[1]. Anyone already using a GLP-1 or any other weight-loss medication at the start was excluded from the analysis ^[1].

After adjusting for baseline food noise scores, the Med+ group's FNQ score fell by an average of 4.05 points, while the Core+ group's fell by 1.15 points — a difference of 3.0 points between the groups on the 20-point scale ^[1]. Unadjusted, the Med+ group's average score dropped from 13.1 to 8.7, and the Core+ group's from 10.7 to 9.7 ^[1]. The authors note the two groups started with significantly different food noise scores, which is why the models adjusted for baseline ^[1].

The authors wrote that the reduction "may serve as an early indicator of treatment response" and is in line with earlier anecdotal reports ^[1].

Several limits are worth knowing. The study is observational, so it can show an association between starting a GLP-1 and a larger drop in food noise, not that the drug caused it ^[1]. Follow-up was only one month, which the authors say was the first time point available for most participants ^[1]. Most participants were white (390 people, or 94%) and female (388, or 93%), with a mean age of 59 and a mean BMI of 34 ^[1]. Which specific GLP-1 medications participants used, at what doses, has not been disclosed ^[1]. And whether the two groups lost different amounts of weight has not been reported — the authors say analyses of weight change and its relationship to food noise are still underway for the full manuscript ^[1]. The findings were presented as a conference poster; the full manuscript has not been published ^[1]. The FNQ itself was developed and validated in a 2025 paper in the journal Obesity ^[1].

Why it matters for patients

Food noise moved from patient slang to a measured quantity in about two years, and this is the first study to compare a GLP-1 plus behavioral treatment against behavioral treatment alone on that measure ^[1]. For patients who describe constant, intrusive food thoughts, that shift matters: it means the experience is now being tracked with a five-question, 20-point tool rather than only in conversation ^[1].

The result is a group average. A 3-point difference between groups does not predict what any one person will feel, and the study did not compare GLP-1 brands, doses or schedules ^[1]. It also says nothing about cost, side effects or whether a lower food noise score translates into better weight, health or quality-of-life outcomes — the authors explicitly call for longer studies to test that ^[1].

What happens next

Additional analyses on weight change and how it relates to changes in food noise are underway for the full manuscript, which will report results beyond the one-month mark ^[1]. The authors say future studies should track food noise over a longer period to understand its role in weight, health and quality of life ^[1].
