What role does WeightLoss Slim DNA play in Abnehmen?

The 'WeightLoss Slim DNA' test is marketed for weight loss, but the scientific evidence is weak. Single genetic variants (e.g., in FTO, MC4R) have only small effects on metabolism or appetite – typically explaining less than 5% of BMI. The results are not diagnostic and should not replace medical advice. Sustainable weight loss depends primarily on calorie balance, diet, and exercise. The test may serve as a motivational tool at best, not as a basis for medical decisions. Evidence: marketing/unclear.
