A wise Man once said The stomach notifies you when it’s Empty unlike the Brain…
That is absolutely correct. The brain itself has no pain receptors and cannot 'feel' emptiness, whereas the stomach sends very clear signals.
Here is how this biological mechanism works:
The stomach's signaling system
Ghrelin: This hormone rises when the stomach is empty.
Brain stimulus: Ghrelin travels via the blood to the hypothalamus.
Gnawing sensation: The stomach wall contracts in the absence of food.
Hunger pangs: This results in the familiar 'feelings of hunger' and stomach sounds.
The silent brain
No pain receptors: The brain tissue itself feels no physical pain or emptiness.
Major consumer: The brain consumes as much as 20% of all body energy.
Indirect signals: In case of energy deficit, the brain causes headaches or loss of concentration, not local pain.
