Cortisol is a stress hormone that plays a complex role in metabolism, but it is not useful for weight loss. Chronically elevated cortisol is strongly linked to increased visceral fat, muscle wasting, and insulin resistance, all of which hinder weight loss. While acute cortisol release can promote lipolysis (fat breakdown), prolonged high levels lead to fat storage, especially in the abdomen. Human studies consistently show that stress-induced cortisol elevation correlates with weight gain and metabolic syndrome. Therefore, managing cortisol through stress reduction, adequate sleep, and a balanced diet may support weight loss indirectly. However, using cortisol supplements or drugs to manipulate levels is not evidence-based and can be harmful. Evidence: human-strong. Sources: none from provided context.
