How are NutriCare | INFINITY DNA-Test and weight loss related?

DNA tests like NutriCare | INFINITY often claim to personalize weight loss strategies, but the scientific evidence is weak. The FTO risk variant (rs9939609) is associated with a small BMI increase (~0.4 kg/m² per allele), but lifestyle factors such as diet and exercise largely override this effect. Other genes like PPARG (rs1801282) influence insulin sensitivity, yet no randomized trials show that DNA-based dietary advice leads to superior weight loss compared to standard recommendations. MyBody-X tests are not diagnostic and are regulated under German GenDG. The evidence for DNA-guided weight loss remains mostly marketing. A safe, evidence-based approach still relies on calorie reduction, balanced nutrition, and regular physical activity.
