Nine weeks flat after five months of steady loss, same dose, same routine, and I cannot tell whether to wait or change something.

Plateau breaking story with a stall: I stalled at 200 lbs for 7 weeks. Tried everything — calorie cycling, increased exercise, more water. Nothing worked.

What finally broke the plateau: a brief dose increase followed by return to maintenance. Lost 12 lbs in the next 3 weeks. Plateaus are temporary — they always break if you stay consistent.

That is correct as far as it goes, and here is where it stops going. 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 is my experience too, for whatever a second data point is worth. The detail I would add is minor and it is already implied above.

Adding the clinical framing, because it changes how the question reads. If two explanations both fit, the useful question is which one predicts something the other does not. That is answerable; arguing about which sounds more plausible is not.
