Why Guessing Is Costing You Years | Episode 95

Most people have no idea that one of the strongest predictors of longevity is not cholesterol, body weight, or even blood pressure.

It’s VO₂ max — your body’s ability to use oxygen to produce energy.

In this episode, Dr. Rob Sumner explains why aerobic capacity is one of the most powerful indicators of long-term health and independence. He shares why generic advice like “eat better” and “exercise more” often fails, and why guessing about your health can cost you years of quality life.

You’ll learn:

• Why VO₂ max predicts longevity
• What happens to aerobic capacity as we age
• Why many people feel tired despite “normal labs”
• The problem with generic fitness advice
• Why measuring your physiology matters

This is Part 1 of a 3-part series exploring the science of metabolism, energy production, and how measuring your body’s systems can help you improve your long-term health trajectory.
