Overview
- Food noise means persistent, distressing thoughts about food that can distract people and drive compulsive eating.
- A recent survey cited in coverage found about a four‑fold fall in reported food noise among people taking GLP‑1 medications compared with prior estimates for people with obesity.
- A 2026 scientific review proposes a mechanism in which GLP‑1 drugs alter the brain’s default mode network to lower arousal to food cues and increase satiety, but the idea remains a developing hypothesis.
- Clinicians urge pairing any medication use with psychological and behavioural work such as mindfulness, attention to internal hunger cues, and removal of easily accessible ultra‑processed foods to lock in lasting habits.
- Use of GLP‑1s is rising in Australia with past estimates around 2% of adults taking them, raising questions about long‑term effects, access and informal markets while research on durability and causation continues.
