"Food noise": what was measured

Why this page exists: this question comes up often in GLP-1 patient forums but rarely in search results. We sampled forum threads by title; we did not quote or identify any user.

It is not a medical term

"Food noise" is a patient phrase for constant, intrusive thoughts about food. There is no agreed definition or validated scale for it, so no trial has measured "food noise" as such.

What was measured in people

In a 20-week randomized study, people on semaglutide 2.4 mg filled out the Control of Eating Questionnaire, a validated survey of hunger and cravings. They reported fewer and less intense food cravings, better control of eating, and less desire for savoury and sweet foods, and ate 35% less at a free-choice lunch.^[1] In a small trial in heavy drinkers, semaglutide reduced weekly alcohol craving too, which suggests the effect reaches beyond food.^[2]

What the animal research suggests

GLP-1 receptors are found in brain areas that regulate appetite.^[3] In mice, the brainstem circuits behind eating less and the circuits behind feeling sick are separate, which helps explain how appetite can drop without nausea.^[4] How this maps onto the human experience of quieter thoughts about food is not yet known.

When the noise comes back

None of the withdrawal trials measured hunger or cravings after stopping. What they show is weight regain, which is consistent with appetite returning; see what happens when you stop.^[5]

• If my thoughts about food have changed a lot, is that something to discuss in terms of my eating or mood?
• If I stop, what is the plan for when appetite comes back?
