Gastrointestinal regulation of food intake.
Despite substantial fluctuations in daily food intake, animals maintain a remarkably stable body weight, because overall caloric ingestion and expenditure are exquisitely matched over long periods of time, through the process of energy homeostasis. The brain receives hormonal, neural, and metabolic signals pertaining to body-energy status and, in response to these inputs, coordinates adaptive a...
متن کاملNervous regulation of food intake.
Q LORIC BALANCE depends upon the regulation of biologic energy exchange. Four important variables are concerned in energy balance : ( 1) food intake, (2) energy storage, (3) energy utilization through activity or work and (4) loss of energy in the production of heat. The caloric balance would thus be regulated by the various mechanisms which regulate the caloric intake in the form of food intak...
متن کاملHormonal regulation of food intake.
Our knowledge of the physiological systems controlling energy homeostasis has increased dramatically over the last decade. The roles of peripheral signals from adipose tissue, pancreas, and the gastrointestinal tract reflecting short- and long-term nutritional status are now being described. Such signals influence central circuits in the hypothalamus, brain stem, and limbic system to modulate n...
متن کاملA Mechanism of Regulation of Food Intake *
Regulation of food intake is a term which includes all of the reactions through which an animal (i) maintains a constant intake while environmental and metabolic conditions are constant, and (ii) adjusts its intake whenever environmental or metabolic conditions are altered. What an animal eats and how much are usually thought to be determined by the energy requirements of the body; but every ca...
متن کاملCentral nervous system regulation of food intake.
Introduction Some 50 years ago, Gordon Kennedy introduced the hypothesis that body fat stores are subject to homeostatic regulation through a process in which afferent signals generated in proportion to body fat mass provide negative feedback to brain areas involved in the control of food intake (1). He further proposed that the central nervous system response to this input is fundamentally cat...
