Recent research provides insights into why people often crave dessert even after eating a full meal. A study published in Science demonstrated that mice, having consumed a standard diet, displayed a strong preference for sugary foods when given a choice, significantly consuming more calories from sugar. The research focused on POMC neurons linked to satiety in the brain's hypothalamus, which released beta-endorphin, suggesting that the appeal of sweet treats may involve neurochemical rewards that override feelings of fullness.
The study reveals that mice, after eating until full, will consume significantly more sugary foods, showing the powerful allure of sweet treats despite satiety.
Research showed that the sugar caused an opioid response in the brain, suggesting a deeper connection between sweet foods and rewarding sensations.
