Summary: New research indicates that combining obesity medications—specifically GLP-1 receptor agonists (GLP-1 RAs)—with a structured behavioral weight management program leads to a substantially larger reduction in “food noise” than behavioral therapy alone.
This study provides the first empirical evidence supporting widespread anecdotal reports that GLP-1 RAs can quiet the persistent, intrusive thoughts about food that often undermine efforts to adopt and maintain healthier eating patterns.
Key Research Findings
- Defining “Food Noise”: Food noise refers to frequent, intrusive, and often uncontrollable thoughts about food that interfere with daily life, focus, and healthy behaviors.
- Greater effect when combined: Both behavioral treatment alone and behavioral treatment with added GLP-1 RAs reduced food noise, but the combination produced a notably larger change.
- Measured impact: Using the validated Food Noise Questionnaire (FNQ), participants who started GLP-1 RAs alongside behavioral therapy (Weight Watchers Med+) showed an adjusted mean FNQ score decrease of 4.05 points, compared with a 1.15-point decrease in the behavioral-only group (Weight Watchers Core+).
- Statistical difference: The between-group adjusted difference in FNQ change was 3.0 points in favor of the GLP-1 RA group over the one-month period measured.
- Potential early indicator: The research team suggests that a rapid drop in food noise after treatment begins could serve as an early sign of how well a patient will respond to weight management interventions.

Overview
Presented at the 33rd European Congress on Obesity in Istanbul, Turkey, the study was led by Dr. Hanim Diktas, a postdoctoral researcher at LSU’s Pennington Biomedical Research Center. This observational cohort study assessed short-term changes in food noise among adults enrolled in a digital behavioral weight management program, comparing those who began GLP-1 RA therapy with those who received behavioral treatment alone.
Food noise has become a focal point in research on obesity and appetite regulation since GLP-1 RAs entered clinical practice. While many patients reported fewer intrusive food-related thoughts after starting these medications, empirical data were lacking. This study addresses that gap by quantifying the short-term change in food noise using a validated instrument.
The study enrolled 417 adults participating in a commercially delivered digital behavioral weight management program. None of the participants were using GLP-1 RAs or other weight-loss medications at baseline. All completed an online survey at the start of the program and again after one month. The analytic comparison included 92 individuals who initiated GLP-1 RAs alongside behavioral treatment (Weight Watchers Med+) and 325 participants who received behavioral treatment without GLP-1 RAs (Weight Watchers Core+).
Food noise was measured with the five-item Food Noise Questionnaire (FNQ), which asks respondents to rate statements on a 0–4 scale (strongly disagree to strongly agree), yielding a total score from 0 to 20. The FNQ statements assess frequency of food-related thoughts, perceived control, time spent thinking about food, negative life impacts, and distraction from daily tasks.
- I find myself constantly thinking about food throughout the day.
- My thoughts about food feel uncontrollable.
- I spend too much time thinking about food.
- My thoughts about food have negative effects on me and/or my life.
- My thoughts about food distract me from what I need to do.
At baseline, participants were mostly female (93%) and white (94%), with a mean age of 59 and a mean BMI of 34 kg/m2. Unadjusted FNQ means decreased from 13.1 to 8.7 in the GLP-1 RA group and from 10.7 to 9.7 in the behavioral-only group. After adjusting statistical models for baseline FNQ scores, the estimated mean change was −4.05 points for Weight Watchers Med+ and −1.15 points for Weight Watchers Core+, with an adjusted between-group difference of −3.0 points favoring the GLP-1 RA group.
Researchers collected body weight via digital scales at both time points and note that additional analyses exploring the relationship between weight change and food noise are in progress for the full manuscript.
The authors conclude that food noise is reduced during weight loss treatment and that initiating GLP-1 RAs alongside behavioral therapy produces a substantially greater short-term reduction than behavioral treatment alone. They recommend future studies with longer follow-up to better understand how changes in food noise relate to weight outcomes, health, and quality of life.
Key Questions Answered:
A: Food noise describes the ongoing, intrusive thoughts about food that can feel uncontrollable, consume time, and negatively affect daily functioning and productivity.
A: Not necessarily. Behavioral interventions alone reduced FNQ scores modestly in this study, but adding a GLP-1 RA produced a much larger short-term reduction—nearly four times greater in this sample at one month.
A: The researchers used the five-question Food Noise Questionnaire (FNQ), which asks participants to rate statements about frequency, control, time spent thinking about food, negative impact, and distraction on a 0–4 scale.
