a physiological need for food, the consequence of food deprivation or timing of external clocks, could be also caused by triggers of learned behavior. Emotional hunger is usually triggered by images of food or emotions and is associated with specific food cravings. Real hunger is more physiological, and appetite is more psychological. Symptoms of food deprivation can start 3-5 hours after eating and build up, progressing from feeling extremely ravenous to experiencing discomfort and pains in the stomach, weakness, and dizziness. 12-16 hours of fasting marks the beginning of noticeable decline in attention, memory, problem solving abilities. Eventually it affects all mental functions as the brain is continually deprived of necessary nutrients. Severe food deprivation leads to vivid hallucinations, confusion, vertigo, and eventually cardiac arrest.
