The pharmacokinetics explain nearly every practical question asked here.

Agreed, and the adaptation point cuts both ways: tachyphylaxis to gastric emptying is why tolerability improves, and it is also why people who were relying on physical fullness feel the effect fade while the appetite effect is still working.

Ask again with the specifics and you will get a better answer than this one.

Agreed on the mechanism, with the caveat that the head-to-head used semaglutide 1mg, not 2.4mg.

Saving this. It is the first explanation that did not require me to already understand it. I will report back once I have actually tried it.

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. The objection nobody has made: this only works if the measurement is doing what we assume it is doing, and that assumption has not been tested here.

That is the short version; the long version is somebody else's post.

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.
