What role does VDR play in Abnehmen?

VDR (Vitamin D Receptor) influences how vitamin D acts in the body. Vitamin D is involved in fat metabolism, insulin sensitivity, and inflammation – all factors that can affect weight loss. Certain VDR variants (e.g., FokI, BsmI) have been associated with small differences in BMI or body fat in observational studies and GWAS, but the effects are modest and inconsistent. A DNA test like MyBody-X can detect these variants, but the predictive value for weight loss is limited. Evidence is mixed: some meta-analyses show weak associations, while others find no significant effect. High-dose vitamin D supplementation without testing blood levels can be harmful (toxicity). Therefore, VDR plays a minor, indirect role in weight loss; lifestyle factors (diet, exercise) are far more important.
