Hormones play a significant role in regulating appetite and weight management. Key hormones like leptin and ghrelin influence hunger and satiety. Leptin, produced by fat cells, signals the brain to reduce appetite, while ghrelin, released by the stomach, stimulates hunger. Hormonal balance is crucial; when disrupted, it can lead to overeating or weight gain. For instance, stress can elevate cortisol levels, increasing cravings for high-calorie foods. Understanding these hormonal interactions can help individuals develop healthier eating habits and effective weight management strategies.
