Can Pharmakogenetik Medicheck help with Abnehmen?

Pharmacogenetics (PGx) examines how genetic variants affect drug metabolism. A test like 'Medicheck' could theoretically provide clues about which medications for obesity (e.g., metformin, GLP-1 analogs) might be more effective or have fewer side effects. However, the evidence for direct weight loss through PGx-based recommendations is weak. Most studies show only moderate effects on the metabolism of individual drugs, not on weight loss itself. Lifestyle, diet, and exercise dominate weight outcomes. Moreover, many commercial PGx tests are based on small samples or European GWAS, limiting generalizability. A PGx test may serve as supplementary information but does not replace medical advice. The evidence level is best described as 'marketing' or 'unclear'.
