The food noise came back three weeks after I reduced my dose, well before the weight moved, which tells me something about which effect tracks what.
What I am after is 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.
I have searched first, so if this is covered somewhere point me at it and I will read it.

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. The detail I would add is minor and it is already implied above.
Clinical perspective, offered as context rather than as advice.
The GLP-1 and alcohol use disorder connection, relevant to food noise: observational data from Scandinavian registries shows reduced alcohol-related hospitalizations in GLP-1 agonist users[1].
The mechanism is plausible: GLP-1R is expressed in the mesolimbic reward pathway (VTA, nucleus accumbens). Agonism at these receptors may reduce the reinforcing properties of alcohol, similar to the reduction in "food noise."
RCTs for GLP-1 agonists in AUD are now underway. If positive, this would be a paradigm-shifting repurposing of existing medications.
