To regulate the food intake human beings have 2 centers called feeding centre and satietary center. Feeding center stimulation leads to increased food intake and uncontrollable hunger where as satietary center stimulation causes cessation of food intake by inhibiting feeding center activity. There are some receptors called glucostats which gives response increase blood glucose content which occurs as soon as the person takes his meal. Glucostats excite the satietary center which inturn inhibits the feeding center.
