Definition
Food noise is a popular term for constant, intrusive thoughts about food. Many people on GLP-1 medicines say it gets much quieter. It is not a medical diagnosis, and no GLP-1 label measures it.
The term came from patients, not textbooks. A 2023 research review notes that people on GLP-1 medicines report less rumination and preoccupation with food, and proposes that food noise is best understood through food cue reactivity: how strongly your body and brain react to the sight, smell or thought of food. Internal states such as hunger can turn that reaction up or down.
There is a plausible reason the noise quiets. The labels say GLP-1 receptors sit in brain areas that regulate appetite, and that semaglutide and tirzepatide lower calorie intake, likely by acting on appetite. The Zepbound label adds that GIP receptors are found in the same areas. But the labels do not mention food noise itself, and how much it drops, and for how long, varies from person to person.
Food noise can also come back, for example during a plateau or toward the end of the dose week; the answers below explain why. At GLP-1 SOS it is one of the changes our community describes most often, and one of the first they notice when it returns.
In the Lab
- Why did my food noise come back on a GLP-1?
- Still hungry on a GLP-1: is it normal and what does it mean?
- How long before a GLP-1 starts working (appetite and weight)
- What 961 people on a GLP-1 told us this month
