In this episode of The New Science of Physical Health, host Shane Stubbs dives into a transformative concept from his book The Perfect Health Lesson: why improving your VO₂ Max is far more critical to longevity than obsessing over your diet. Drawing on decades of research and expert insights, Shane explores the science of hazard ratios and their role in evaluating the impact of health interventions.

  • The Misconception About Food: While diet plays a role in health, its contribution to longevity pales compared to the overwhelming benefits of improved cardiovascular fitness.
  • The Power of VO₂ Max: Shane explains why VO₂ Max, the maximum rate at which your body can utilize oxygen during exercise, is the most powerful metric for reducing clinical risk and extending lifespan.
  • Hazard Ratios Demystified: Learn how hazard ratios provide evidence-based insights into which interventions—like improving fitness—offer the most significant health benefits.
  • Evidence vs. Popular Belief: Shane challenges the pervasive belief that diet is the ultimate health determinant, debunking myths fueled by marketing and social media influencers.
  • Practical Takeaways: Discover why raising your VO₂ Max should be your top priority and how this focus can naturally lead to better overall health decisions, including healthier eating habits.


    • This episode is a must-listen for anyone ready to cut through the noise of health fads and focus on the evidence-backed strategies that truly matter for longevity. Join Shane as he unpacks the surprising science that puts cardiovascular fitness at the forefront of the longevity conversation.
