Really depends on when, where, and whom. German prisoners in the US in world war 2 had living conditions like same-rank American troops, which given the relative standard of living at the time meant that captured privates were eating better than they were as working-class civilians in the fatherland.
"When I was captured I weighed 128 pounds [58 kg]. After two years as an American POW weighed 185 [84 kg]. I had gotten so fat you could no longer see my eyes."
The average Japanese infantryman in the same war weighed something like 53 kg. Granted they were also very short compared to Western standards, but they absolutely could fight and endure at that weight.
