"Hunger and sleep, argues Dan Skovronsky, the firm’s chief scientific officer, are both 'master homeostasis mechanisms'—systems that keep the body in balance. When they misbehave, illness follows. That, he says, helps explain why incretins, the hormone family behind GLP-1, proved so broadly useful. Hence why orexins could be just as important."

Also, orexins are peptides, like semaglutide (Ozempic), although in a different family.

Ozempic == GLP-1 which the first visible paragraph is discussing.

Ozempic is the poster boy for peptides.
