ZOE Science & Nutrition - Could fasting extend your lifespan? | Dr. Valter Longo and Prof. Tim Spector
The discussion highlights the difference between chronological age (number of years lived) and biological age (health of cells). Biological age can be influenced by lifestyle choices, such as diet and fasting. Dr. Walter Longo and Tim Spector explore how fasting, particularly the fasting-mimicking diet, can potentially reduce biological age and improve health outcomes. They emphasize that while fasting can have significant short-term benefits, its long-term effects need further study. The fasting-mimicking diet involves consuming a low-calorie, low-protein, high-fat, plant-based diet for a few days periodically, which mimics the effects of fasting without complete food deprivation. This approach has shown promise in reducing biological age and improving conditions like diabetes. However, they caution against extreme fasting and stress the importance of a balanced diet, particularly reducing ultra-processed foods, to support overall health and longevity.
Key Points:
- Biological age can differ significantly from chronological age and is influenced by lifestyle choices.
- Fasting, especially the fasting-mimicking diet, can reduce biological age and improve health.
- The fasting-mimicking diet involves low-calorie, low-protein, high-fat intake for a few days periodically.
- Extreme fasting can have negative long-term effects; a balanced diet is crucial.
- Reducing ultra-processed foods is important for health and longevity.

- Blocking pathways related to sugar and amino acids can extend yeast lifespan fivefold, illustrating the potential for nutrient manipulation in aging.
- Yeast deprived of nutrients and with blocked pathways can extend their lifespan tenfold, suggesting a significant interplay between nutrient availability and genetic pathways.
- Low nutrient levels trigger a maintenance mode in organisms, potentially increasing lifespan by delaying reproduction until conditions improve, which could be applicable to broader biological contexts.
- Yeast demonstrate a hundredfold lifespan extension by entering a spore state, a form of hibernation until nutrients are available, indicating potential strategies for longevity.
