I think this is related to some theories about how the body processes food as it approaches its rest period or something like that. I have not read any of the articles or theories, but I have heard the idea repeated many times, and across the world (heard it in the US, hear it here in Russia). I'm not sure if there is any validity to it really so much as just giving yourself a stopping point for the day, but I have not done any research in this regard.
