I switched from injectable to oral semaglutide for travel reasons and the fasting window is proving harder to hold than the injection ever was.
The narrow version of the question is whether the fasting requirement is as strict in practice as the label implies, and what people actually see when they get it wrong.
If the honest answer is that nobody knows, that is a useful answer and I would rather have it.
Answering the narrow version, because the broad one does not have a single answer. Orforglipron is the more interesting oral story because it is not a peptide at all. Being a small molecule it does not need SNAC, does not need the fasting window, and has oral bioavailability in the tens of percent rather than about one.

Agreeing with DataDave, and the qualification matters more than the agreement. The absorption variability is real, but it partly averages out over weeks — the steady-state trough is less erratic than any single day would suggest. Where it bites is in the first fortnight, when people conclude the tablet does nothing.

This matches mine closely enough to be worth saying so. The OASIS programme put 50mg oral in the same territory as 2.4mg injectable — around 15% mean weight loss — but it needed a dose 20 times larger to get there because almost none of the tablet is absorbed. The dose numbers are not comparable across routes and quoting them side by side confuses people.
Adding the clinical framing, because it changes how the question reads. Take it one variable at a time. Almost every unanswerable question in these threads is unanswerable because three things changed in the same fortnight, and no amount of subsequent argument can untangle them after the fact.
