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 11 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 $161/month on alcohol. Triple win.
RunnerRach said: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.
RunnerRach 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.

"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.

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.
