HUEC 3010 Chapter : Control Of Food Intake
Document Summary
Control of food intake: homeostasis: consistency of internal environment / physiological processes that maintain it. Behavioral component of energy homeostasis: food intake: maintains body fat content / energy balance, regulation vs. control of energy balance. Regulation: capacity to maintain a consistent physical parameter regardless of variety in the. Internal / external environment: describes the performance of a variable as opposed to a specific mechanism, requires a sensor that directs the response that preserves the regulated parameter. Energy production may be the regulated variable: not body weight / energy balance. Control: exercise of influence / direction over a process / response. Achieved through the operation of controlled processes / responses. Food intake regulation: food is incapable of regulation due to internal / external environments. Controlled as a means to regulate some physiological variable: set-point theory of weight control. The human metabolism will adjust itself to maintain a comfortable weight.
