welche diät passt zu mir — what does this mean exactly?

The question 'which diet suits me' refers to whether DNA or microbiome tests can provide personalized dietary advice. MyBody-X offers such tests, but the evidence is often weak. Variants like TCF7L2 have only small effects on blood sugar; diet response depends heavily on lifestyle and individual variation. Microbiome tests reveal bacterial composition linked to insulin resistance, but data are observational, not causal. A continuous glucose monitor (CGM) gives more direct feedback. In short: these tests can suggest broad directions but cannot prescribe a precise diet. The science is still emerging, and marketing often overstates predictive power. True personalization requires repeated measurements and medical guidance.
