I'm interested in when this will hit me. I know that for my week-long section hikes I have virtually no hunger at all until I start to drive home. I assume that at some point after than normal hunger returns followed by a ravenous appetite.

I would think it would affect different people with different body types in different ways. Obviously someone that is getting below their ideal body weight will be getting triggers from the brain to eat and eat a LOT. I am wondering if someone still being over their ideal body weight gets similar Hiker Hunger or does it only really kick in until later.
