Cortisol is primarily a stress hormone, and chronically elevated levels are strongly linked to weight gain, especially visceral fat accumulation, muscle breakdown, and increased cravings for high-calorie foods. While cortisol does have some metabolic effects (e.g., mobilizing glucose), these are not beneficial for sustainable weight loss. In fact, long-term stress and high cortisol are associated with obesity and metabolic syndrome. There is no credible evidence that intentionally raising or supplementing cortisol aids weight loss; such approaches would likely backfire. Weight management strategies should focus on stress reduction, adequate sleep, balanced nutrition, and regular physical activity rather than manipulating cortisol.
