Myths vs facts: NutriCare | INFINITY DNA-Test and Abnehmen

DNA tests like NutriCare or INFINITY are often marketed with promises of personalized diets that make weight loss easier. The fact is: there are indeed genetic variants (e.g., in the FTO gene) associated with increased obesity risk. However, the evidence that a diet based on these genes leads to significantly better weight loss than a standard diet is weak. Most studies show only small or inconsistent effects. Additionally, hormone status (e.g., cortisol, thyroid hormones) is sometimes mentioned as a complementary factor – a hormone test can indeed uncover relevant disorders, but a pure DNA test does not replace clinical evaluation. MyBody-X markets these tests as 'metabolic analysis,' but the scientific basis for direct weight reduction through gene-based diets is currently rated as 'mixed.' Consumers should have realistic expectations: a DNA test can provide hints, but it cannot work miracles. Without a calorie deficit and exercise, even the best genetic analysis will not cause weight loss.
