The relationship between hormones and weight management is complex, as hormones regulate metabolism, appetite, and fat storage. Key hormones, such as insulin, leptin, and ghrelin, play significant roles in signaling hunger and energy expenditure. Insulin, for instance, helps manage blood sugar levels and can promote fat storage when levels are chronically elevated. In contrast, leptin (produced by fat cells) signals satiety, while ghrelin (produced in the stomach) stimulates appetite. Hormonal imbalances can disrupt weight management efforts, making it challenging to achieve and maintain a healthy weight.
