How to prepare for Longevity Ernährung

Preparing for a 'longevity diet' should be based on evidence-backed principles: a predominantly plant-based, high-fiber diet with healthy fats (e.g., Mediterranean diet), moderate caloric restriction, and adequate protein to preserve muscle mass. Intermittent fasting may be supportive but is not suitable for everyone. DNA-based diet recommendations (e.g., based on MTHFR or PPARG) have very weak evidence and are not recommended by medical societies. Microbiome tests provide only a snapshot with high day-to-day variability and are not clinically validated to guide personalized longevity nutrition. Instead of expensive genetic tests, blood markers (homocysteine, vitamin D, lipids) and medical advice are more useful. Beware of overblown claims: no test can prescribe the perfect anti-aging diet.
