What role does Longevity DNA Test play in Abnehmen?

The MyBody-X Longevity DNA Test is marketed to support weight loss, but the scientific evidence is weak. It analyzes single genetic variants (e.g., MTHFR, FTO) with small effect sizes that are often not clinically meaningful. Weight loss is primarily determined by calorie balance, diet, and physical activity, not genetics. The test may provide lifestyle inspiration but cannot replace medical advice. Evidence is marketing/unclear; no validated clinical claims. Caveat: genetic predisposition does not guarantee weight loss outcomes.
