Insulin, leptin and reward
Open accessAbstract
Feeding for pleasure, or "non-homeostatic feeding", potentially contributes to the rapid development of obesity worldwide. Obesity is associated with an imbalance of regulatory hormones which normally act to maintain stable energy balance and body weight. The adiposity hormones insulin and leptin are two such signals elevated in obesity with the capacity to dampen feeding behavior through their action on hypothalamic circuits which regulate appetite and metabolism. Recent evidence suggests that both hormones achieve this degree of regulation by inhibiting the rewarding aspects of feeding behavior, perhaps by signaling within midbrain reward circuits. This review describes the capacity of both insulin and leptin to regulate reward-related behavior.

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.”

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.
