The thing that changed for me was not hunger, it was that the constant background negotiation about food simply stopped, and I had not realised it was constant until it was not.
So the question, as narrowly as I can put it: whether the quiet is the same mechanism as the appetite suppression or a separate one, because they seem to come and go on different schedules.
Numbers rather than impressions, if you have them.

Neuroscience perspective on food noise:
GLP-1 receptors are expressed throughout the CNS, with high density in the hypothalamic arcuate nucleus, area postrema, and — critically — the mesolimbic reward pathway[1].
This is directly relevant to food noise because the central effects of GLP-1 agonists extend far beyond simple appetite suppression. The reduction in "food noise" that patients describe is likely mediated by modulation of dopaminergic signaling in the VTA and nucleus accumbens.
The emerging data on reduced addictive behaviors (alcohol, gambling) further supports this mechanism. food noise should be understood in this broader neurobiological context.

Rebound hunger after missed dose of food noise: I missed my injection by 3 days due to a shipping delay and the hunger came ROARING back. Like a switch flipped. It was eye-opening to feel the difference.
This experience actually reinforced my understanding of what the medication does — it's not just "suppressing appetite," it's normalizing dysregulated hunger signaling. When the drug wears off, you feel the full force of what it was managing.

Same pattern here, and in the same order. I had assumed I was the exception until I read this.
Adding the clinical framing, because it changes how the question reads.
"Food aversion" side effect of food noise that I wasn't prepared for: I used to LOVE cooking and trying new restaurants. Now certain foods — especially fried foods — literally repulse me.
It's not just reduced appetite; it's an active disgust response. My therapist says this is common and likely related to the reward pathway modulation. It's mostly a positive change, but I do miss enjoying food the way I used to.
