This topic describes the role of stomach cues, blood signals (e.g., Insulin / plasma glucose levels, circulating leptin or ghrelin concentration) and the brain in the regulation of food intake and appetite. Particular focus will be made to delineate the neural and hormonal mechanisms that underlie the gut–brain axis and its interaction with the neural reward network in the regulation of appetite and satiety. Several biological factors, including genetic predisposition and changes in gut microbiota that may contribute to obesity and related-diseases, will also be highlighted.
