What role does Pharmakogenetik Medicheck play in weight loss?

Pharmacogenetics (Medicheck) examines how genetic variants affect drug response and tolerability. In weight loss, it becomes relevant when medications like metformin, GLP-1 agonists, or appetite suppressants are prescribed. A genetic test may indicate whether a person is likely to respond better to a specific drug or has an elevated risk of side effects. However, the evidence for a direct, clinically meaningful weight reduction through pharmacogenetic testing is weak. Most studies show only modest effects, and lifestyle modification remains the primary driver of weight loss. Many commercial providers overstate the predictive power of such tests. Therefore, a Medicheck should not be used as a standalone weight loss strategy but only as supplementary information under medical supervision. Without a specific medication in mind, its role in weight loss is questionable.
