Understanding Hormones and Weight Management
Hormones play a critical role in regulating body weight and eating habits through a complex interplay of signals between the brain and the body. Leptin, a hormone released by fat stores, informs the brain about how much fat is present, helping to regulate food intake. Additionally, hormones from the gastrointestinal tract relay information about recent meals, which further influences hunger and satiety. This dual signaling mechanism highlights the layered complexities of weight management, suggesting that hormonal balance is pivotal in understanding the struggles some individuals face in maintaining their desired weight.
