What to watch with DNA Stoffwechseltest and Abnehmen?

A DNA metabolism test (e.g., MyBody-X) can identify variants like FTO (obesity risk) or ADRB2 (possible VO₂max influence), but effect sizes are small – most weight loss depends on calorie balance, exercise, and sleep. Evidence for DNA-guided weight loss is moderate: FTO risk carriers may benefit slightly from higher protein intake, but it's no guarantee. Be aware that such tests are not diagnostic and cannot rule out metabolic disorders. Marketing often overstates predictive power; many 'metabolism genes' have weak or conflicting evidence. Use the test as a motivational tool, not a diet prescription. Safety note: before major dietary changes (e.g., low-carb, high-protein), consult a doctor, especially if you have pre-existing conditions.
