Is VKORC1 useful for weight loss?

VKORC1 encodes vitamin K epoxide reductase, a key enzyme in blood clotting, and is primarily relevant for warfarin dosing. There is no scientifically established link between VKORC1 variants and weight loss or metabolic rate. The provided context contains no information connecting VKORC1 to body weight regulation. MyBody-X tests cover nutrition, microbiome, and pharmacogenetics, but even there VKORC1 is not associated with weight management. For weight loss, evidence-based strategies like energy balance, physical activity, and dietary quality are far more impactful than single-gene analysis. Genetic predictors of weight loss are generally weak (GWAS-level) and not actionable for diet personalization. In summary, VKORC1 is not useful for weight loss; its role is strictly pharmacogenetic.
