insights INSIGHT
VO2 Max and Metabolism
Peter Attia realized his high VO2 max but low PVO2 max suggests inefficient energy use, potentially linked to a high metabolism.
This inefficiency might explain his leanness despite high food intake, but also indicates suboptimal power output.
insights INSIGHT
Carbohydrate Intake in Endurance Sports
Elite endurance athletes now consume incredibly high levels of carbohydrates, sometimes up to 240g/hour, exceeding traditional limits.
This increased fuel intake is a major factor in the dramatic performance improvements seen in sports like cycling and Ironman.

VO2 Max Testing Protocol
Test VO2 max in ideal conditions, minimizing travel and testing at your usual training time.
Warm up thoroughly with zone two, threshold work, and bursts at your expected PVO2 max.
