Why do we feel hungry, weak, or lightheaded at all, when the body can just burn the stored fat?

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.

Others mention the lag in extracting energy from our fat.

But I want to raise another point, that , hunger, weakness, lightheadedness are not just due to lack of energy in the body. E.g. dehydration can cause lightheadedness

Weakness can be due to muscle fatigue or damage which can be due to things like lactic acid buildup, decrease in oxygen due to oxygen being used up, and muscle fibre damage.
