Numerous factors influence appetite and hunger signals, including hormonal changes, psychological factors, and dietary habits. Ghrelin, known as the hunger hormone, triggers appetite, while leptin signals fullness. Stress and emotional states can also alter eating behaviors, leading to emotional eating. Additionally, the type and quality of food consumed affect these signals; for instance, foods high in fiber and protein can promote satiety more effectively than processed sugars. Understanding these factors can enhance self-regulation in eating.
