Alcohol relationship change with food noise: I used to drink 3-4 beers 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 $175/month on alcohol. Triple win.
A narrower follow-up, since the general answer is now clear:
How would you tell the difference between that and the alternative explanation?

"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 heavy cream sauces — 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.

raj_cambridge 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.

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.
