This gets cited here weekly, usually second-hand, so it is worth setting out what it does and does not establish.

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.

Where I think it is weakest: the comparator does most of the work in how this gets reported, and it is not the comparator most people think they are citing.

The question I want answered is whether the fasting requirement is as strict in practice as the label implies, and what people actually see when they get it wrong. I would rather have one careful answer than five confident ones.

Note on sourcing:
Figures above are from the primary publication rather than the press summary. If a number here disagrees with one you have, post yours and we will work out which of us is reading a secondary source.

Agreeing with EndoResFellow, and the qualification matters more than the agreement. Oral semaglutide is absorbed in the stomach with the help of SNAC, which locally raises pH and protects the peptide long enough to cross. That mechanism is fragile: bioavailability is roughly 1% and highly sensitive to gastric contents, so a mouthful of coffee genuinely changes the exposure. This is why the label wants 30 minutes and no more than half a glass of plain water.

Happy to go further on any of that.

I do not accept that the fasting window is a minor inconvenience. Adherence data on daily orals with timing requirements is consistently worse than weekly injections, and a drug you take imperfectly is a lower dose than the one on the box.

Short answer first, then the reasoning. 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.

Can confirm. Same sequence, different timescale. The detail I would add is minor and it is already implied above.
