What to watch with Cortisol and weight loss?

Cortisol (the stress hormone) can significantly impact weight loss. Chronically elevated levels promote visceral fat storage, increase appetite (especially for carbs/sugar), and may slow metabolism. When interpreting consumer tests (DNA or biomarkers), caution is warranted: many tests claim to determine 'cortisol sensitivity' based on gene variants (e.g., NR3C1, FKBP5). However, the evidence is weak – such SNPs explain only a tiny fraction of individual stress responses. More reliable are salivary or blood cortisol measurements at specific times (morning, evening) or the dexamethasone suppression test. Sleep quality, stress management, and a balanced diet are also critical. MyBody-X currently does not offer specific cortisol genetics. Caveat: No DNA test can tell you how much weight you will lose or gain due to stress. If you suspect Cushing's syndrome or adrenal fatigue, consult a physician.
