Chronically eating rich foods reduces the pleasure associated with high-calorie foods. The culprit is a neuronal protein called neurotensin, whose production is affected by diet, a study has found. While this may seem counterintuitive, restoring its normal level could help treat obesity, the researchers conclude.

Did you know that an overly rich diet or obesity significantly reduce the pleasure provided by high-calorie food? The culprit behind this apparent paradox is a protein produced by certain neurons and called neurotensin, which strongly influences the "reward circuit" based on dopamine, reveals new research on mice published in the journal Nature. Results that the authors hope will ultimately be useful for the treatment of obesity and perhaps eating disorders.
