To feel less hungry, it’s helpful to understand the roles of the hormones leptin and ghrelin. Leptin suppresses appetite and boosts energy expenditure, while ghrelin stimulates hunger. Three effective methods to increase leptin and decrease ghrelin are regular exercise, sufficient sleep, and a balanced diet rich in protein, fiber, and healthy fats. In summary, exercise, sleep well, and eat a nutritious diet to feel less hungry and achieve better appetite control.
