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.
What would genuinely help is knowing 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 would rather have one careful answer than five confident ones.

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.

Central vs peripheral GLP-1R signaling in food noise: elegant studies using brain-penetrant vs peripherally-restricted GLP-1 agonists show that ~80% of the weight loss effect is centrally mediated[1].
The key brain regions: arcuate nucleus (appetite), area postrema (nausea), NTS (satiety), VTA/NAc (reward). Peripheral effects (gastric emptying, insulin secretion) contribute but are secondary for weight loss.
This has implications for next-gen drugs: optimizing brain penetration and CNS receptor occupancy may be more important than systemic exposure.

Mine went the same way, slower. The detail I would add is minor and it is already implied above.
From the other side of the consultation, briefly.
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.
