Evidence check: WeightLoss | SLIM DNA-Test in the context of Abnehmen

The SLIM DNA Test (metabolism test) claims to personalize weight loss diets based on genetic variants. However, the scientific evidence is limited. A systematic review (PMC12482741) shows only small effect sizes for gene-diet interactions. Most weight differences are explained by lifestyle factors like calorie balance, exercise, and sleep. Polygenic risk scores for obesity explain less than 5% of variance and are ancestry-specific. The test may serve as additional motivation but does not replace evidence-based dietary counseling. Caveat: results are not clinically diagnostic and should not be the sole basis for drastic dietary changes. Consult a doctor or registered dietitian.
