a. Hunger is closely related to the amount of glucose present in the blood.
b. When the level of glucose is low, a cascade of events leads to production of many proteins, including a hormone called Ghrelin.
c. Secretion of ghrelin takes place in the stomach when it’s empty. Upon its secretion, the stomach starts having hungerpangs or contractions that generate hunger signals that reach the brain and give us the feeling of hunger.
d. When the glucose level is high, i.e. the stomach is full, another hormone called Leptin is secreted which suppresses the feeling of hunger.
