If you're hungry, surely the evolutionarily 'rational' action is to prioritise eating. That seems to be what's happening, certainly for those lucky enough to be able to control who eats and when.
But I guess you meant more generally in evolution. Yes, but the question is how does the body prioritize eating in situations where food is not available but hunger is? If food is not obvious, it must be sought. Increase the noise in the search algorithm, would seem to maximize state space exploration in food quest, which seems something evolution would then pass on.
Better than cargo culting anyway hahaha! :)
