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 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 $191/month on alcohol. Triple win.

...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.

Adding a me-too, because a thread of one person's experience is not much use. I had assumed I was the exception until I read this.

Clinical perspective, offered as context rather than as advice.

Central vs peripheral GLP-1R signaling in food noise: elegant studies using brain-penetrant vs peripherally-restricted GLP-1 agonists show that ~80% of the weight loss effect is centrally mediated[1].

The key brain regions: arcuate nucleus (appetite), area postrema (nausea), NTS (satiety), VTA/NAc (reward). Peripheral effects (gastric emptying, insulin secretion) contribute but are secondary for weight loss.

This has implications for next-gen drugs: optimizing brain penetration and CNS receptor occupancy may be more important than systemic exposure.
