There's another aspect past the fact that hungry kids are cranky.
Maslow's hierarchy of needs says a person who is hungry cannot learn, so for unschooling I think that could be the very first consideration.
When a family doesn't consider learning the primary goal of unschooling, things can disintegrate pretty quickly. YES, once you get it going kids are learning all the time. But if a family starts with the idea that learning is happening all the time, they might never quite get the learning part of unschooling going. And in that case learning will NOT happen all the time. It's subtle but crucial.
