What should I know about langsamer stoffwechseltyp?

The term 'slow metabolism type' originates from commercial DNA tests and lacks a clear scientific definition. Metabolic rate is influenced by many factors – muscle mass, age, hormones, physical activity, and diet – not by single gene variants. Studies on genes like FTO (e.g., PMID 37813841) show an association with obesity risk but no clinically useful effect on individual diet recommendations. Professional guidelines advise against such genetic tests for dietary guidance (PMID 38474735). To support metabolism, rely on proven strategies: adequate protein, resistance training, sleep, and stress management. A so-called 'slow metabolism type' is not a medical diagnosis. Be cautious of expensive tests promising simple answers – the evidence is weak to nonexistent.
