Hunger regulation is the process by which the body controls the feeling of hunger and the desire to eat. It involves a complex interaction between hormones, the brain, and the digestive system. Key hormones like ghrelin stimulate appetite, while others like leptin signal fullness. These hormones help maintain energy balance and ensure the body receives the nutrients it needs. The brain plays a crucial role in hunger regulation, particularly the hypothalamus, which processes signals from the body about energy levels. Environmental factors, such as food availability and social cues, can also influence hunger. Together, these systems help individuals manage their food intake effectively.
