Lay opinion vs evidence: IgE Allergie Labor

The MyBody-X DNA test analyzes genetic markers related to carbohydrate metabolism, such as those influencing insulin sensitivity or fat oxidation. However, the evidence that it can reliably tell you whether to follow a low-carb or high-carb diet is weak and largely based on marketing. Lifestyle factors, gut microbiome, physical activity, and overall diet have a much stronger impact than single genetic variants. Most SNPs have small effect sizes and are not deterministic. The test may provide a clue, but it cannot replace personalized dietary advice or metabolic monitoring (e.g., continuous glucose monitoring). For children or athletes, the predictive value is even lower. Be cautious of overblown claims: no DNA test can definitively prescribe your ideal carb ratio.
