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.

A narrower follow-up, since the general answer is now clear:

Did your prescriber agree with that reading, and if not what was their objection?

Phantom hunger vs real hunger on food noise: learning to distinguish between the two has been a revelation. Real hunger: gradual onset, physical stomach sensation, any food sounds good. Phantom hunger: sudden, emotionally triggered, specific food cravings, occurs right after eating.

The GLP-1 agonist suppresses real hunger beautifully. Phantom hunger still pops up but I can now recognize it for what it is — an emotional signal, not a physical need. Mindfulness training helped enormously with this distinction.

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.
