But we have multiple links or causes for eating.
Different factors start and terminate eating.
Reular mealtimes, or friends eating, engender hunger at set times, and hunger can diminish after a mealtime even if we do not eat. Our blood's level of glucose and fatty acids plays a role in hunger. We have reserves of these, releasing them when needed. The brain needs glucose and the body fatty acids. Current evidence locates these detectors in the liver.
