Understanding Hunger and Satiety Signals
The episode examines the complexities of hunger and satiety signals, particularly focusing on the role of the hormone leptin. Leptin, which is secreted by fat cells, communicates with the hypothalamus in the brain to regulate energy balance and appetite. However, modern dietary patterns, characterized by high sugar and refined carbohydrate intake, can lead to leptin resistance, where the brain no longer responds effectively to leptin signals. As a result, individuals may experience increased hunger and overeating, making weight management significantly more challenging.
