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

The question of why you are not losing weight is complex and cannot be answered by a single test. Many commercial tests (e.g., DNA diet tests, hormone or nutrient checks) promise personalized insights, but scientific evidence is often weak. A randomized controlled trial (PMID 37813841) found no benefit of DNA-based dietary advice for weight loss. Hormone measurements are unreliable due to daily fluctuations and individual variability. Nutrient tests can detect deficiencies, but a single reading does not replace clinical evaluation. What you can do yourself: Keep an honest food and activity diary, prioritize sleep and stress management. Reduce processed foods and sugar, increase protein and fiber intake. Exercise (both strength and cardio) is essential. Do not be misled by 'miracle tests' – sustainable weight loss requires long-term lifestyle changes. If you suspect medical issues (thyroid, insulin resistance), consult a doctor. No single test will give you the answer.
