Appetite control refers to the body's ability to regulate hunger and satiety, influencing how much food we consume. 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, helping to maintain energy balance. Various factors can affect appetite control, including stress, sleep, and diet. For instance, lack of sleep can increase levels of ghrelin, leading to increased hunger. Additionally, consuming high-fiber foods can enhance feelings of fullness, aiding in better appetite management and overall health.
