This one has a reasonably settled answer, so here it is. Most of what circulates confidently in this community traces back to one summary of one study, and the qualifier was dropped somewhere in the third retelling.
I am tired in a way that does not respond to sleep, which is different from the tiredness I had before any of this started.
Worth checking before concluding it is the drug: ferritin, B12, TSH, and total intake for three honest days. Two of those four explain most cases.
The question I want answered is whether the fatigue is a direct drug effect or simply the caloric deficit, because the answer changes what you do about it.
Practical detail welcome, however dull — the duller the better.

True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.

Mine went the same way, slower.
Adding the clinical framing, because it changes how the question reads. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.
