Energy and Macronutrient Intake Regulation: Independent or Interrelated Mechanisms?
The initiation and termination of feeding are complex processes involving many signals and their integration in the central nervous system. Fluxes of metabolic fuels should logically be determinants of both the initiation and termination of feeding to meet energy needs of the organism, but the relationships of these fluxes to the regulatory centres in the central nervous system are presently undefined. Furthermore, it has become clear that the ingestion, digestion and metabolism of carbohydrate, fat and proteins provides a wide array of signals to the central nervous system and that these signals influence not only the quantity of food consumed but also the composition of the chosen foods. The purpose of this presentation is to highlight these influences and their role in food intake regulation and to provide examples of linkages between body fuel composition, central nervous system neurotransmitters and feeding behaviour.
