Peter Attia MDPeter’s takeaways on aerobic exercise and VO2 max, insulin resistance, and more (PS 4 sneak peek)
At a glance
WHAT IT’S REALLY ABOUT
Peter Attia Reviews Olav Episode: VO2 Max, Testing, and Carbohydrate Fueling
- Peter explains aerobic metrics such as functional threshold power, critical power, and PVO2 max, noting critical power is easier to calculate from several short tests.
- He reflects that his own high VO2 max relative to his power suggests inefficiency, which may pair with unusually high energy expenditure for his body weight.
- Olav's discussion of carbohydrate intake, with elite athletes now tolerating 150 to 240 grams per hour, is described by Peter as arguably the most important takeaway for high-performance athletes.
- Peter lays out a detailed warm-up protocol for VO2 max testing and describes how he trains with one interval day and three zone two days per week.
- The episode is a sneak peek that previews upcoming summaries of Ralph, Saum, Trenna, and Mike before pitching premium membership for the full version.
IDEAS WORTH REMEMBERING
5 ideasCritical power is easier to measure than FTP
Peter says critical power can be derived from curves built on three to four shorter tests, making it a handier benchmark than a one-hour effort or a discounted 20-minute test.
A high VO2 max relative to power may signal inefficiency
Peter's VO2 max has been well above that of better cyclists with higher FTP, which Olav suggested reflects aerobic over-training, anaerobic under-training, and needing more energy per watt.
Inefficiency may come with high energy expenditure
Peter notes his metabolic tests consistently show very high energy expenditure for his body weight, which could help him stay lean even though he uses energy inefficiently.
Carbohydrate tolerance has dramatically expanded in elite endurance sport
The old view was about 60 grams of glucose per hour, but Pogačar was taking in 150 to 180 and world-class triathletes are being pushed to 240, which Peter says comes from training the GI system.
Peak endurance is framed as an energy transfer problem
Peter argues that more energy input allows more output, and that the roughly doubled fuel feedstock is a more appealing explanation for performance gains than unknown drugs.

what we've seen over the past decade is quite literally a more than doubling of the feedstock that goes into the furnace.
