Document Summary
Web module intro to hunger and satiety. Food seeking is as much a lifestyle as it is a necessity: a goal directed behavior, more than about nutrition, bring people together to share life, also gives you pleasure. Hunger drives feeding behavior: satiety signals help us stop eating. Smell is just as important as taste in guiding feeding behavior: there is an interaction between sense of taste and smell. Selective pressures still exist for feeding behaviors in modern context. Hunger + satiety cycles throughout the day. At night : we fast for longest period of daily cycle. Many signals between brain and digestive system happen when hungry that drive our feelings of hunger to consume food / drink. Satiety signals: lead us to stop consumption. Blood glucose levels regulate feelings of hunger and satiation. When fasting: one main reasons you feel hungry is because low glucose levels.
