What should I know about warum kann ich nicht abnehmen?

The question 'Why can't I lose weight?' is complex and usually multifactorial. Genetic factors play a role but are rarely the sole cause. From the available data: variants in genes like MC4R (rs17782313) can slightly influence appetite and BMI, and MTNR1B (rs10830963) is linked to blood sugar and sleep. APOA2 (rs5082) interacts with saturated fat intake – some people may be more sensitive. However, effect sizes are small. The evidence is based on GWAS and observational studies, not clinical diagnoses. More important are often lifestyle factors: calorie balance, sleep quality, stress, thyroid function, medications, and eating behavior. A genetic test alone cannot explain a weight loss plateau. Many carriers of risk variants have no weight issues. Consumer DNA tests provide hints, not certainty. Beware of exaggerated diet claims. A medical check-up (e.g., thyroid, insulin resistance) and a sustainable, realistic dietary approach are advisable. Genetics can help personalize your strategy but does not replace professional guidance.
