The process of doing those things (even mental activity) depletes nutritional stocks we've established, and thus we need to replenish them to be at our peak condition. (It may be that we need different types of nutrition for the different activities.) Of course, we also have to balance that with our overall accumulation of nutrition lest we find our weight increasing, and we have to watch the type of nutrition lest we find our teeth decaying or our bodies subject to various ills.
