On short final to land Runway XXR we heard a 'too low; flaps' audible warning. As the PM; I saw we were at flaps 25 with a planned flaps 30. I called this out to the First Officer who was the flying pilot as I selected flaps 25 and performed the landing check which we had apparently missed on approach. We made a normal landing. This was our second day in a row of very early flights with wake up calls and 3 time zone changes. While I didn't feel fatigued; I suspect I was more tired than I realized. We had just flown a nearly 5 hour cross country flight with a breakfast of a couple spoonfuls of granola; a couple spoonfuls of yogurt; and a few grapes. This was our company provided meal for the flight. While I normally take responsibility for providing my own food; this is not always possible in the current COVID environment. I believe this was a significant contributing factor. In hindsight; the proper response would have been to perform a go around and set up for another approach. While I don't feel my handling of the situation was unsafe; it was not consistent with company procedures. With reasonable sleep and nutrition I'd like to think I would have made a different decision.
Air carrier Captain reported receiving a flap aural warning message due to having an incorrect flap setting on final approach.
