FMD and High-Performance Lifestyles

Today I’m joined by Professor Valter Longo to unpack what actually slows biological ageing, and what most women are getting wrong about fasting, protein, and diet.

We explore the difference between chronological age and biological age, how biological ageing is measured, and why chasing extreme fasting or high-protein trends may quietly undermine long-term health. Professor Longo shares decades of research behind the Fasting Mimicking Diet (FMD), explains why most popular fasting protocols may increase cardiovascular risk, and outlines the dietary patterns consistently linked to the world’s longest-living populations.

This conversation cuts through longevity hype with evidence from human trials, centenarian studies, and 100 years of ageing research, offering a grounded, practical framework for improving healthspan without extremes.

WHAT YOU’LL LEARN

• The real difference between chronological age and biological age – and how it’s measured

• Why blood biomarkers may be more reliable than epigenetic ageing clocks right now

• What organ-specific ageing clocks reveal about hidden health risks

• How long it actually takes to activate meaningful autophagy in humans

• Why most intermittent fasting protocols may increase heart disease risk

• The science behind the 5-day Fasting Mimicking Diet (FMD)

• FMD vs water fasting: gut health, muscle preservation, and safety

• Why skipping breakfast is linked to higher cardiovascular mortality

• The optimal daily eating window for longevity (and why 12 hours matters)

• How often to use FMD for longevity, metabolic health, and disease prevention

• Why excess protein may accelerate ageing and disease risk

• How much protein humans actually need for longevity

• The ideal macronutrient balance for healthspan and lifespan

• How nutrition consistently outperforms exercise for lifespan extension

• Practical longevity habits around sleep, stress, and lifestyle timing
