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 3-4 beers most nights. Since starting GLP-1 therapy, I have zero interest in alcohol. Haven't had a drink in 9 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 $207/month on alcohol. Triple win.

Phantom hunger vs real hunger on food noise: learning to distinguish between the two has been a revelation. Real hunger: gradual onset, physical stomach sensation, any food sounds good. Phantom hunger: sudden, emotionally triggered, specific food cravings, occurs right after eating.

The GLP-1 agonist suppresses real hunger beautifully. Phantom hunger still pops up but I can now recognize it for what it is — an emotional signal, not a physical need. Mindfulness training helped enormously with this distinction.

Same pattern here, and in the same order.

From the other side of the consultation, briefly.

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.
