Hormones play a key role in hunger regulation from "summary" of The Obesity Code by Dr. Jason Fung
Hormones are the messengers of the body, relaying important information to different organs and tissues. When it comes to hunger regulation, hormones play a crucial role in determining when we feel hungry and when we feel full. One of the key hormones involved in hunger regulation is insulin. Insulin is released by the pancreas in response to rising blood sugar levels, signaling to the body that it has been fed. Leptin is another important hormone that plays a role in hunger regulation. Leptin is produced by fat cells and acts on the brain to signal that the body has enough energy stores and does not need to eat. However, in cases of obesity, the body can become resistant to the effects of leptin, leading to a disruption in hunger regulation. Ghrelin is yet another hormone that influences hunger. Ghrelin is produced by the stomach and signals to the brain that it is time to eat. Levels of ghrelin typically rise before meals and fall after eating. However, in cases of obesity, ghrelin levels can become dysregulated, leading to increased hunger and overeating. In addition to insulin, leptin, and ghrelin, there are several other hormones involved in hunger regulation, including cholecystokinin (CCK), peptide YY (PYY), and glucagon-like peptide-1 (GLP-1). These hormones work together to send signals to the brain about hunger and fullness, helping to maintain a balance in the body's energy stores.- Hormones play a key role in hunger regulation by signaling to the brain when to eat and when to stop eating. When these hormonal signals become dysregulated, as is often the case in obesity, it can lead to increased hunger, overeating, and weight gain. By understanding the role of hormones in hunger regulation, we can begin to address the root causes of obesity and work towards achieving lasting weight loss.
