From the other side of the consultation, briefly. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

This matches mine closely enough to be worth saying so out loud. Posting only so the count is not one.

There is a second half to this that has not been said yet. The pharmacokinetics explain nearly every practical question asked here. Albumin binding above 99% slows clearance enough to make weekly dosing possible; a terminal half-life near a week means four to five weeks to steady state and therefore a four-week titration interval; subcutaneous bioavailability around 89% means injection site barely matters. Those three facts answer most timing questions before they are asked.

I would rather be corrected than agreed with, if it comes to it.

Adding the numbers, since they settle part of this. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

Worth separating that from the pharmacology, which this thread keeps folding into the same question. They behave differently and the advice does not transfer.

Reporting back.

Six weeks on from posting: I stopped reading the weekly number and started reading a four-week average, and the "stall" I opened this thread about was a 1.8kg loss I could not see.
