Hunger Signals

Scientific / Technical Definition

Hunger signals refer to the physiological and psychological cues that indicate the body's need for energy intake. These signals are regulated by complex interactions between the digestive system, endocrine system, and the hypothalamus in the brain, which processes hormonal signals such as ghrelin, leptin, and insulin to regulate appetite and energy balance.
