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.

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.

Alcohol relationship change with food noise: I used to drink 2 glasses of wine most nights. Since starting GLP-1 therapy, I have zero interest in alcohol. Haven't had a drink in 5 months.

The "food noise" reduction seems to extend to other reward-seeking behaviors, including alcohol. My liver enzymes have improved, my sleep is better, and I've saved roughly $239/month on alcohol. Triple win.

Can confirm. Same sequence, different timescale. Nothing to add that would improve it.

Adding the clinical framing, because it changes how the question reads.

"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 red meat — 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.
