hunger signaling

Hunger signaling involves a complex communication system between the stomach, brain, and hormones. When the stomach is empty, it releases hormones like ghrelin that signal the brain’s hunger center, prompting the desire to eat. After eating, the stomach stretches and hormones like leptin and insulin increase, signaling fullness. These signals help regulate energy intake, ensuring we consume enough nutrients while avoiding overeating. The balance of these hormonal signals and neural responses is essential for maintaining healthy weight and energy levels.
