INFINITY DNA-Test | inkl. 28-Tage-Plan & Rezeptbuch: which diet helps?

The INFINITY DNA Test with a 28-day plan and recipe book claims to provide a personalized diet recommendation based on your genes. However, the scientific reality is sobering: polygenic scores for weight loss and metabolism have very limited predictive power. Effect sizes of individual gene variants are small, and most studies suffer from ancestry bias. The claim that a DNA test can determine the 'best' diet for you is marketing-driven and not supported by current evidence. Instead, lifestyle factors such as calorie balance, macronutrient distribution, and meal timing dominate dietary success. The 28-day plan may serve as a structured guide, but the genetic component is negligible for the vast majority of people. A balanced, sustainable diet (e.g., Mediterranean diet) rich in fiber, healthy fats, and protein is evidence-based and suitable for most. Caution against overinterpretation: No DNA test replaces medical advice or individualized nutritional counseling by a professional. Safety: As long as you avoid drastic changes (e.g., extreme low-carb without medical supervision), the test is harmless as a motivational tool. But do not rely blindly on the genetic results.
