Feast or famine? How appetite cells in the brain respond to fasting

Feast or famine? How appetite cells in the brain respond to fasting: Previous work has shown that the AgRP neurons promote feeding and weight gain, while the POMC cells have been linked with appetite suppression and weight loss. Now a new study uncovers a neural pathway that links fasting with activation of AgRP neurons. The research provides valuable insight into the complex mechanisms that control food seeking behavior.
