Document Summary
If we all have hunger and eating systems whose primary function is to maintain energy levels at optimal levels, then eating disorders should be rare. Insulin does three things: promotes the use of glucose as the primary source of energy by the body. It promotes the conversion of the blood borne fuels to forms that can be stored; glucose to glycogen and fat and amino acids to proteins. Theories of hunger and eating: set points vs. Lipostatic theory was thought to account for long-term regulation: set-point theories of hunger and eating are inconsistent with basic eating-related evolutionary pressures, major eating-related problem faced by our ancestors was the inconsistency and unpredictability of the food supply. Factors that determine what, when, and how much we eat. Learning to eat vitamins and minerals: when an animal is deficient in sodium, it develops an immediate and compelling preference for the taste of sodium salt. Role of blood glucose levels in hunger and satiety.
