Food noise: Conceptual, methodological, and ethical considerations

The term "food noise" has rapidly entered scientific, clinical, commercial, and public discourse, particularly in relation to appetite changes reported during treatment with glucagon-like peptide-1 receptor agonist (GLP-1) medications. Despite growing use of the construct and the emergence of dedicated measurement tools, limited evidence exists regarding its underlying mechanisms, whether it reflects a distinct phenomenon, and how it is experienced and interpreted in the context of everyday life. In this commentary, we critically examine current conceptualizations and measurement approaches to food noise, focusing on their theoretical grounding, psychometric development, clinical interpretation, and de-contextualization. We review how existing definitions relate to broader literature on food cue reactivity, food preoccupation, cravings, and intrusive food-related cognitions, and discuss whether food noise reflects a distinct construct or an overlapping dimension of established appetite-related processes. We highlight uncertainties surrounding current measurement instruments, including conceptual overlap with existing scales and limited evidence on clinical utility. Beyond psychometric concerns, we examine how meanings attached to food-related thoughts and "noise" may vary across contexts, raising challenges for translation of the construct. Rather than rejecting food noise as a potentially meaningful construct, we identify important unresolved questions and set priorities for future research, including stronger theoretical specification, mixed-methods instrument development grounded in lived experience, cross-cultural validation, consideration of its potential to reclassify common experiences as pathology, and clearer criteria for distinguishing and treating clinically significant food-related cognitions. We argue that this conceptual, methodological, and normative clarity is needed before food noise can be responsibly integrated into clinical use.
