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
The question I want answered is 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. Happy to be told the question itself is wrong.
