warum nehme ich nicht ab test — can a DNA test help?

A DNA test can provide some insights into genetic variants that influence metabolism, such as those related to fat metabolism (e.g., rs662799 for triglycerides), carbohydrate sensitivity (e.g., rs7903146 for diabetes risk), and lactose tolerance (rs4988235). However, these effects are small and do not directly explain why you are not losing weight. Weight loss is a complex process influenced by calorie intake, physical activity, sleep, stress, hormones, and medical conditions like hypothyroidism or insulin resistance. A DNA test cannot measure your current metabolic rate, hormone levels, or adherence to a diet. The evidence for DNA-based weight loss recommendations is mixed: while some associations are supported by GWAS, randomized controlled trials showing that acting on these variants leads to better weight loss are lacking. Many commercial tests overhype their utility. Therefore, a DNA test may offer interesting clues but is not a reliable tool for diagnosing weight loss difficulties. If you are struggling, a medical evaluation (blood work, thyroid panel, glucose tolerance) and consultation with a registered dietitian are more evidence-based approaches. The test should be seen as a novelty, not a solution.
