What does it really mean to be metabolically flexible? In this episode of Beyond Healthspan, Brandon and Rich unpack one of the most important papers on exercise metabolism and mitochondrial health—coauthored by Dr. George Brooks and Dr. Inigo San Millán.

They break down how your body switches between fat and carbs for fuel, what lactate actually tells us about fitness and aging, and how to evaluate and improve your own metabolic flexibility—no lab required.

Whether you’re an athlete, healthspan-focused, or trying to optimize your metabolism, this episode delivers science-backed insights you can apply right now.
