wie kann ich mein mikrobiom verbessern — what are common causes?

A single TCF7L2 variant does not mean you are insulin resistant or should avoid all carbs. TCF7L2 is associated with a slightly increased risk of type 2 diabetes, but the effect size is small. There is no strong evidence that carriers must eliminate carbohydrates. A balanced diet with whole grains and legumes is generally recommended. DNA tests like MyBody‑X provide suggestive information, but they are not diagnostic. For personalized advice, combine genetic data with blood markers (fasting glucose, HbA1c) and consult a healthcare professional. Evidence: unclear, based on limited association studies.
