Homeostatic and hedonic signals interact in the regulation of food intake

Abstract

Food intake is regulated by 2 complementary drives: the homeostatic and hedonic pathways. The homeostatic pathway controls energy balance by increasing the motivation to eat following depletion of energy stores. In contrast, hedonic or reward-based regulation can override the homeostatic pathway during periods of relative energy abundance by increasing the desire to consume foods that are highly palatable. In contrast to the consumption of food, the motivation to use drugs of abuse is mediated only by the reward pathway. In this article we review the extensive research that has identified several mechanisms by which repeated exposure to drugs of abuse alters neuronal function and increases the motivational incentive to obtain and use these substances. We then compare our current understanding of drug-induced changes in neuronal reward circuitry with what is known about the consequences of repeated consumption of highly palatable foods such as high-fat and high-sugar diets. Next, we discuss the normal homeostatic regulation of food intake, which is a unique aspect of food addiction. Finally, we discuss the clinical implications of these neuronal adaptations in the context of obesity and neuropsychiatric syndromes such as bulimia nervosa and Prader-Willi syndrome.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Insulin and leptin appear to negatively modulate the food rewarding system, whereas ghrelin exerts opposite effects.

    “Furthermore, insulin and leptin appear to negatively modulate the food rewarding system [67], whereas ghrelin exerts opposite effects [68]; the changes in these hormonal concentrations following sleep restriction could therefore contribute to the increased hedonic, rather than homeostatic, eating, that may be typical of short sleepers.”
  • Food intake is regulated by hedonic and homeostatic systems that historically served to maintain mean BMI within a healthy range under widely varying environmental conditions.

    “Food intake is regulated by hedonic and homeostatic systems (3) that historically served to maintain mean BMI within a healthy range under widely varying environmental conditions.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
