ECO 2026: adding a GLP-1 to behavioral treatment cuts food noise measurably more

Researchers reported at the 33rd European Congress on Obesity in Istanbul that adults who began a GLP-1 receptor agonist while enrolled in a digital behavioral weight-management program saw a significantly larger one-month drop in "food noise" than people in the same program who did not start a medication ^[1]. The work was presented by Dr. Hanim Diktas, a postdoctoral researcher at LSU's Pennington Biomedical Research Center in Baton Rouge, and colleagues ^[1].

"Food noise" is defined in the study as persistent, intrusive thoughts about food that disrupt daily life and make healthy behaviors harder ^[1]. The term spread through patient communities as GLP-1 drugs became widely used, and reports that the medications quiet those thoughts have largely been anecdotal. The researchers note there had been no empirical evidence testing whether GLP-1 drugs reduce food noise more than behavioral treatment alone ^[1].

What the study measured

This was an observational cohort study of 417 adults in a digital behavioral weight-management program ^[1]. Participants completed an online survey at baseline and again about a month later, using the validated Food Noise Questionnaire (FNQ) ^[1]. The FNQ asks five questions scored 0 to 4 each, for a maximum of 20 points. The statements cover constantly thinking about food, feeling that food thoughts are uncontrollable, spending too much time thinking about food, food thoughts having negative effects on life, and food thoughts causing distraction ^[1].

Of the 417 people, 92 started a GLP-1 receptor agonist alongside behavioral treatment (labeled "WeightWatchers Med+, GLP-1 RA") and 325 did not start a medication while receiving behavioral treatment ("WeightWatchers Core+, No GLP-1 RA") ^[1]. Anyone already using a GLP-1 or other weight-loss medication at baseline was excluded ^[1]. Body weight was collected with digital scales at both time points ^[1].

The sample was not diverse: 390 participants (94%) were white and 388 (93%) were female, with a mean age of 59 and a mean BMI of 34 kg/m² ^[1].

The numbers

Baseline FNQ scores differed significantly between the two groups, with the medication group starting higher ^[1]. Unadjusted, the Med+ group's mean score fell from 13.1 to 8.7, while the Core+ group's fell from 10.7 to 9.7 ^[1].

Because the starting points were different, the researchers adjusted their statistical models for baseline FNQ score, which they said allowed them to isolate the effect of GLP-1 use on score changes ^[1]. In those adjusted models, food noise dropped significantly in both groups: an adjusted mean change of −4.05 points in the Med+ group and −1.15 points in the Core+ group, for an adjusted between-group difference of −3.0 points on the 20-point scale ^[1].

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

Why it matters for patients

Until now, the claim that GLP-1 drugs quiet food noise rested mostly on what people said online and to their clinicians. This study puts a number on it using a questionnaire that was formally developed and validated and published in the journal Obesity ^[1]. That gives clinicians and researchers a common yardstick instead of relying on descriptions alone.

The limits matter too. This was an observational cohort, not a randomized trial, so people chose whether to start a medication, and the two groups differed at baseline in how much food noise they reported ^[1]. The follow-up was only one month, which the authors said was chosen because it was the first time point available for most participants ^[1]. They wrote that longer follow-up is needed to understand the role food noise plays in weight, health and quality-of-life outcomes ^[1].

The source does not say which specific GLP-1 medications participants started, at what doses, or how much weight either group lost. Analyses of weight change and its relationship to food noise change are still underway for the full manuscript ^[1]. Whether a 3-point difference on a 20-point scale translates into how people actually feel day to day is also not addressed in the material presented. And because the sample was overwhelmingly white, female and around age 59, the findings may not describe younger people, men or other groups ^[1].

What happens next

The poster was presented during the congress the week of May 13, 2026 ^[1]. Conference posters have not gone through full peer review. The research team says additional analyses tying weight change to food noise change are in progress for the full manuscript, though no publication date is given ^[1].
