Is Cortisol useful for Abnehmen?

Cortisol is a stress hormone that regulates metabolism and fat storage. Chronically elevated cortisol – due to prolonged stress, poor sleep, or unbalanced diet – is consistently linked to increased visceral fat and weight gain, not weight loss. For weight loss (Abnehmen), cortisol is therefore counterproductive: high levels can inhibit fat breakdown, promote muscle wasting, and trigger cravings. Some direct-to-consumer tests (e.g., salivary cortisol day curves) are marketed as tools to optimize metabolism, but the evidence is weak. While a disrupted cortisol rhythm may indicate stress, measuring it alone rarely leads to sustainable weight loss without clinical interpretation. Weight management requires a holistic approach: calorie balance, exercise, sleep, and stress reduction. Single-gene variants (e.g., in the glucocorticoid receptor) have negligible effects. Conclusion: Cortisol is not useful for weight loss; if you aim to lose weight, focus on stress reduction rather than hormone testing.
