Evidence check: Cortisol senken in the context of Abnehmen

The idea of lowering cortisol to support weight loss is biologically plausible: chronic high cortisol promotes visceral fat storage and cravings. However, evidence for specific 'cortisol-lowering' interventions (e.g., supplements like ashwagandha, phosphatidylserine, or adaptogens) is often weak or conflicting. Most studies are small, short-term, or lack placebo controls. Moreover, a DNA test like MyBody-X does not measure current cortisol levels—it only indicates genetic predispositions that may influence cortisol metabolism (e.g., variants in NR3C1 or FKBP5). These typically have small effect sizes and are not clinically actionable on their own. Without a salivary or blood cortisol test, any claim about cortisol remains speculative. For sustainable weight loss, evidence-based approaches—sleep hygiene, stress reduction (mindfulness, exercise), and a balanced diet—are more effective and safer than unverified supplements. Beware of marketing hype: 'lowering cortisol' is not a guaranteed path to weight loss.
