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.

Alcohol relationship change with food noise: I used to drink cocktails most nights. Since starting GLP-1 therapy, I have zero interest in alcohol. Haven't had a drink in 7 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 $169/month on alcohol. Triple win.

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.

This matches mine closely enough to be worth saying so out loud. Posting only so the count is not one.

Clinical perspective, offered as context rather than as advice.

...regarding food noise mechanism of action...

To build on this — the mechanism is more complex than "it makes you less hungry." GLP-1 agonists:

1. Activate hypothalamic satiety centers (appetite reduction)
2. Delay gastric emptying (prolonged fullness)
3. Potentiate glucose-dependent insulin secretion
4. Suppress glucagon secretion
5. Modulate reward pathway dopaminergic signaling
6. Reduce hepatic lipogenesis
7. 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.
