Evidence check: DNA Stoffwechselanalyse | inkl. 28-Tage-Plan & Rezeptbuch in the context of longevity

The DNA metabolism analysis with a 28-day plan and recipe book is a commercial product based on single SNPs (e.g., FTO, PPARG, TCF7L2). The effects of these variants on metabolism are generally small and overshadowed by lifestyle factors. A 28-day plan can promote healthy eating habits, but the genetic personalization is weakly supported by evidence. In the longevity context, no direct studies show that such a plan extends lifespan. The evidence is primarily marketing-driven. Caution: Not a clinical diagnostic tool; individual blood markers (e.g., HbA1c, lipids) are more informative. The plan may serve as a motivational tool but should not replace medical advice.
