A mechanism of regulation of food intake.
Year: 1953
Type: article
Abstract: 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 careful observer who has conducted feeding experiments knows that there are many circumstances in which the amount of food eaten is not related to energy expenditure. For example, most mammals will not eat when they are deprived of water, because the demand for energy is secondary to preventing dehydration. They also fail to eat when placed in a hot environment with free access to water and food. There is, therefore, no simple correlation between energy needs and food intake which is valid under all conditions, and it is our purpose now to present the hypothesis that the important factor in regulation of food intake is not its energy value, but rather the amount of extra heat released in its
