Evidence check: MY FOODBOOK in the context of Abnehmen

The MyBody-X DNA Nutrition Test analyzes genetic variants such as rs9939609 in the FTO gene, which is associated with a slightly increased BMI risk. Evidence comes from GWAS studies showing modest effects: the A allele occurs in about 41 % of Europeans and confers a small risk increase for overweight. The test can provide clues about metabolic traits or nutrient needs, but weight loss is primarily driven by calorie balance, physical activity, and behavior. Genetic contributions are small and not diagnostic. The test is useful as a general guide, but it should not replace personalized dietary counseling or medical evaluation. Be cautious not to overinterpret results – a single gene does not determine weight loss success. Evidence level: GWAS-based, moderate association. Not clinically diagnostic.
