When we need energy, can’t the body just burn the stored fat? Isn’t that the whole point of stored fat? Why will we feel hungry, weak, lightheaded, etc. at all? I understand if the body doesn’t have enough fat (if you’re super skinny), it would make sense to feel hungry, but I don’t understand why would that be the case if there’s enough fat to go around.

A) it takes time to break down fat into usable energy
B) the brain is wired to control eating behavior so it’s consistent. Even if you do survive without eating for a few more hours these mechanisms don’t care about it. Evolutionary wise that’s adaptive since it forces you to think about gathering food, because in the wild food is scarce.
