Don’t forget the many, many hours spent weaving simple fabrics and baskets, cutting down and grinding wood and rocks into tools, lifting small wooden houses, fighting off annoying and nasty bugs, the many trips to bring water from a reliable source to the camp, maybe going 1 or 2 days without food because there are no edible plants/fruit around and the hunter party couldn’t get shit. You better not be squeamish about eating just about every part of animals, including brain, tongue, eyes, intestines, lungs, bone marrow.

Probably little to no seasoning to whatever you happen to eat, either. Salt? Good fucking luck if you’re far from the sea.
