warum nehme ich nicht ab — what can you do yourself?

Why you aren't losing weight is usually multifactorial – rarely a single genetic answer. DNA tests for weight loss (e.g., MyBody-X 'DNA Ernährungs-Test') are marketed as a key, but evidence is weak: SNPs explain only a tiny fraction of weight variation, and no RCT shows DNA-based diets outperform standard advice. What you can do yourself: Create a modest calorie deficit (300–500 kcal below maintenance), prioritize protein and fiber, combine strength and cardio exercise, get 7–9 hours of sleep, manage stress, and be patient. Common pitfalls include hidden liquid calories, oversized portions, and low non-exercise activity thermogenesis (NEAT). Medical causes like hypothyroidism, insulin resistance, or medications should be ruled out by a doctor. Avoid extreme diets that may slow metabolism. Bottom line: Rely on proven lifestyle habits, not consumer genetic tests. Evidence for the latter is 'marketing/unclear'.
