I posted this question on the Outdoors SE site. There were some good points regarding morale and such, but I'm curious about this question from a purely biological/nutritive perspective.
Copying from other question:
What is the difference between eating a little bit of food at an interval and eating enough to be full at once?
I'm getting the same amount of calories/nutrition** regardless of when I consume it, so who cares? Why not just eat whenever you're hungry to the point of satiety?
Is that an overly-simplistic view?
** I suppose there could be a difference in the percentage of nutrients absorbed. If I get too much of a nutrient, perhaps my body will excrete it, so, in that case, it's better to consume it periodically when your body needs it.
The scenario is being stranded somewhere not knowing when rescue will come - so generally no activity.
** is the only counter argument I can think of, but then again, if you're hungry, that tells you that your body needs the nutrients, so maybe it's better to just eat now rather than wait.
P.S. before my question on OutdoorsSE was edited, I was also asking about hydration, so comments on that would be nice too, though maybe that warrants a separate question.
