#173 - AMA #26: Continuous glucose monitors, zone 2 training, and a framework for interventions

The Peter Attia Drive

In this “Ask Me Anything” (AMA) episode, Peter and Bob answer numerous follow-up questions to recently discussed deep-dive topics such as the use of continuous glucose monitors and getting the most from zone 2 exercise. They also discuss the incredible feats of cyclists in the Tour de France through the lens of the amazing performance physiology required from these athletes. Additionally, Peter ties the conversation together by sharing his foundational framework when considering different interventions, even in the absence of data from a randomized controlled trial. If you’re not a subscriber and listening on a podcast player, you’ll only be able to hear a preview of the AMA.
