This is the version of the explanation I wish somebody had given me, written down before I forget what confused me. It is about a stall, and it is deliberately narrow — everything I am not confident about is marked as such.
What is actually established
Genuine plateaus happen too, and the mechanism is metabolic adaptation plus a smaller body. A body 20kg lighter needs meaningfully fewer calories at rest and less to move, so the deficit that produced the first phase is arithmetically smaller now. The options are the honest ones — increase the deficit slightly, increase activity, or accept the new plateau — and escalating the dose is only one of them.
The condition it depends on
The early-responder data is relevant to expectations: roughly 3% loss by week four at a therapeutic dose predicts a strong result at a year. It does not mean someone below that will not respond, but it changes how long you should wait before changing something.
What I am not sure about
The bit I cannot resolve on my own is how to distinguish a genuine plateau from measurement noise and creeping intake, before changing anything. I would rather have one careful answer than five confident ones.

Agreed, and for anyone with an eating-disorder history this needs a clinician in the loop rather than a forum. The same drug can be therapeutic in binge-eating disorder and actively harmful in a restrictive disorder.
If somebody has the primary source to hand I would rather cite it than paraphrase it.

This is where I part company with the consensus forming above. The "it is your intake" reflex here gets tiring. Some people genuinely stop responding at a dose that worked, and telling them to track harder when they have already tracked is how people stop posting.

View ResultsTaking the question as asked, rather than the general version of it. Most reported plateaus are not plateaus. Weight is a noisy signal — daily variation of one to two kilograms from glycogen, sodium and gut contents — so a fortnight of flat readings is well inside the noise band. Before concluding anything, look at a rolling weekly average over at least four weeks and at a tape measure, because recomposition shows up in circumference before it shows up in weight. Then track intake honestly for a week: appetite suppression fades unevenly, and intake creeping back up is the single commonest cause.

This matches mine closely enough to be worth saying so out loud. I had assumed I was the exception until I read this.
