What role does CYP2D6 play in Abnehmen?

CYP2D6 is a drug-metabolizing enzyme that breaks down many medications – including some that can affect body weight (e.g., certain antidepressants, beta-blockers, opioids). However, CYP2D6 itself has no direct role in fat metabolism or calorie burning. Genetic variants (e.g., poor vs. ultrarapid metabolizer) can alter drug efficacy and side effects, which may indirectly influence weight. For targeted weight loss, there is no robust evidence that CYP2D6 testing is useful. Most claims from direct-to-consumer tests are exaggerated or purely mechanistic. A physician should be consulted before any medication change. Evidence: mechanistic/practice, no strong clinical trials for weight loss.
