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

The question of why you are not losing weight is complex and cannot be reduced to a single factor. Caloric balance (energy intake vs. expenditure) is central, but hormones, sleep, stress, medications, and genetic predisposition also play a role. A microbiome test can provide insights into the composition of your gut bacteria, which theoretically influence metabolism and nutrient absorption. However, the scientific evidence that such a test directly leads to weight loss is weak. Most studies are observational and show correlations, not causation. There are no standardized, clinically validated microbiome profiles that can reliably guide a personalized diet for weight loss. A test can offer interesting insights, but it does not replace a medical evaluation of thyroid function, insulin resistance, or other metabolic disorders. Without accompanying lifestyle changes, a microbiome test alone is unlikely to cause weight loss. Be skeptical of exaggerated claims. The evidence is mixed and mostly mechanistic or from small studies. A test can be useful as part of a holistic approach, but not as a standalone solution.
