Questions people ask about Longevity Genetik

A DNA test for nutrition can identify genetic variants that modestly influence metabolism, such as those in FTO (appetite regulation), TCF7L2 (blood sugar), or ADRB3 (fat burning). However, effect sizes are small; lifestyle factors like diet, exercise, and sleep have a far greater impact. The evidence is mostly from GWAS and observational studies, not robust clinical trials. Be skeptical of claims that a DNA test alone can prescribe a personalized diet. Use results as a general guide, not a prescription. For reliable interpretation, consult a registered dietitian or physician. Many direct-to-consumer tests overstate their predictive power – look for transparent methodology and independent validation.
