Splitting this out of the general thread because the answers kept arriving in ones and twos and nobody could see the shape of it.
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.
The bit I cannot resolve on my own 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.
Roughly, people seem to land in one of these:
- Held where they were and waited it out
- Changed one variable and kept everything else fixed
- Changed several things at once and cannot now attribute the result
- Stopped and reassessed from a clean baseline
Say which and say why — the why is the useful half.

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.

Second this. The detail I would add is minor and it is already implied above.
Clinical perspective, offered as context rather than as advice.
"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 heavy cream sauces — 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.
