In this episode, I'm re-airing the first debate ever held on the Boundless Life podcast, with repeat guest Jay Feldman and Duke obesity medicine physician Dr. Eric Westman going head to head on whether your cells run better on carbohydrates or fat. The carbs-are-good, carbs-are-bad argument has only gotten louder, and this is still the best version of it I've heard.

You'll hear Jay's case that burning fat creates more oxidative stress and drives up stress hormones like glucagon and cortisol over time, and Eric's case from decades of reversing type 2 diabetes in his clinic. We get into the KetoSAge study that pulled keto-adapted women out of ketosis, the KETO Trial on keto dieters with very high LDL cholesterol, what a failing heart actually burns, and why keto adaptation can take months.

We close on the membrane pacemaker theory of aging, survival versus thriving, how I scale my own carbs to training and travel, and the three carb levels Eric lays out in End Your Carb Confusion. Whether you eat keto, high-carb, or somewhere in between, this debate will sharpen how you think about fuel.
