What should I know about warum nehme ich nicht ab?

The question 'Why am I not losing weight?' cannot be answered by a single genetic test. DNA tests (e.g., MyBody-X) can identify variants like rs1800206 (FTO) associated with slightly higher BMI, but effect sizes are small (beta ~0.07 per copy) and heavily influenced by lifestyle, environment, and ancestry. Microbiome tests show gut diversity but lack direct causal evidence for weight loss. IgG food allergy tests are not validated for true allergies and may lead to unnecessary restrictions. Evidence for personalized diet recommendations from these tests is weak (GWAS/mechanistic). Key drivers of weight loss remain calorie balance, sleep quality, stress management, and physical activity. Testing can offer general hints but does not replace medical evaluation for persistent weight plateaus.
