Detailed explanation-1: -The feeling of hunger is controlled by a hormone called Ghrelin. When our stomach is empty it produces Ghrelin which further sends the signal to our brain, which in turn produces stomach contractions which are felt as hunger pangs.

Detailed explanation-2: -These are commonly known as hunger pangs. Hunger pangs, or hunger pains, are caused by strong contractions of the stomach when it’s empty. This uncomfortable sensation is often accompanied by hunger, or the desire to eat. Despite being called “hunger” pangs, these pains don’t always indicate a true need to eat.

Detailed explanation-3: -The brain triggers the release of a hormone called ghrelin in response to an empty stomach or in anticipation of the next meal. Ghrelin signals the body to release stomach acids to digest food. If food is not consumed, the stomach acids begin to attack the lining of the stomach, causing hunger pains.

Detailed explanation-4: -Hormones. The physical sensation of hunger comes from contractions of the stomach muscles. These contractions are believed to be triggered by high concentrations of the hormone ghrelin. Two other hormones, peptide YY and leptin, cause the physical sensations of being full.
