Collecting this in one place because it comes up every few weeks and the answer is always assembled from scratch. It is about food noise, and it is deliberately narrow — everything I am not confident about is marked as such.
What is actually established
Food noise is the best term this community has produced and it describes something the trials did not measure well: the constant background computation about food that most people with obesity live with and most people without it do not believe exists. GLP-1 agonism reduces the salience of food cues in the reward pathway rather than simply reducing hunger, which is why the reported experience is silence rather than willpower. It is also why its return on dose reduction is the first thing people notice, well before the weight moves.
The condition it depends on
It is worth naming the loss side of it. Food was a source of pleasure and structure, and its removal can leave a gap that people are not prepared for.
What I am not sure about
What would genuinely help is knowing whether the quiet is the same mechanism as the appetite suppression or a separate one, because they seem to come and go on different schedules. Tell me what I have not thought of.

"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.

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 $171/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.

Mine went the same way, slower. Nothing to add that would improve it.
