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.
The narrow version of the question 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.
Not looking for reassurance. Looking for the part I have got wrong.

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.

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.

Mine went the same way, slower. Posting only so the count is not one.
From the other side of the consultation, briefly.
SleepDoc_PDX said:...regarding food noise mechanism of action...
To build on this — the mechanism is more complex than "it makes you less hungry." GLP-1 agonists:
- Activate hypothalamic satiety centers (appetite reduction)
- Delay gastric emptying (prolonged fullness)
- Potentiate glucose-dependent insulin secretion
- Suppress glucagon secretion
- Modulate reward pathway dopaminergic signaling
- Reduce hepatic lipogenesis
- Have direct cardiovascular protective effects
It's a multi-target drug with systemic metabolic effects. Understanding the mechanism helps us predict and manage side effects.
