If you’re dying of hunger, why can’t you eat leaves and grass to survive? Could that sustain you for even a little longer?

Question

And what would be the most advantageous things to come across if you have dwindling supplies? Berries? An animal?

Answer 1

Depending on what kind of leaf, you may or may not be able to get some nutrition from it (spinach — yes, oak leaves — no). Same with grass.

It takes energy to digest something. If you don’t get more calories from digesting it than the digestion (or elimination) takes, you’ve just sped things along more quickly.

As a side note, digestion (and elimination — from either end) takes water from your body also. So if water is also scarce, you’ve done yourself a double disservice.
