Food noise has emerged as a new term to describe a preoccupation with food that can be persistent, intrusive, and unwanted. Anecdotal reports suggest that taking a glucagon-like peptide-1 (GLP-1) receptor agonist medication may reduce or even eliminate food noise. However, little is known about the nature of food noise or how people experience it. The present study aimed to better understand how people conceptualise and experience food noise, and examine whether people taking a GLP-1 medication experience significantly less food noise than those contemplating taking one (“contemplators”). We also explored whether food noise is associated with impulsivity or self-reported memory. Over 600 participants, either taking or contemplating taking a GLP-1 medication, completed an online survey via Qualtrics. Food noise was measured by the Food Noise Questionnaire and Ro Allison Indiana Dhurandhar Food Noise (RAID-FN) Inventory. Participants taking GLP-1 medications reported substantial reductions in food noise after commencing treatment. However, more than half reported that their food noise increases as they approach their next dose, and most feared their food noise returning. Compared to contemplators, GLP-1 users reported significantly lower food noise and impulsivity, as well as better self-reported memory. Most participants reported that food noise is like a craving, but not like hunger. Perceptions of food noise differed between groups; GLP-1 users perceived food noise as significantly more negative than contemplators. Finally, over 25% of participants reported that shopping, social media, and sweetened soft drinks occupied their thoughts in the same way that food does during food noise. More than 15% reported the same for alcohol, vaping or smoking, and sex. Drawing on the accounts of over 600 people with lived experience, this study suggests that experiences of food noise are heterogeneous and that current conceptualisations of food noise may benefit from incorporating cravings.
