Fitness | LifestyleCheck: which diet helps?

There is no single 'best' diet for everyone. DNA tests like those from MyBody-X can provide clues about how your body processes fats, carbs, or micronutrients, but the effect sizes are small and the evidence is mixed (evidence: mixed). A balanced diet tailored to your preferences and tolerances is more effective than a purely gene-based approach. Important: Do not supplement based solely on genetic variants without blood tests, especially for iron or vitamin D. MyBody-X tests offer interesting background information but do not replace professional dietary advice.
