Welcome!And thanks for listening.In this episode, I have the incredible opportunity to sit down with one of my lifelong mentors in both medicine and endurance running, Dr. Tim Noakes. I first discovered his work when I started running marathons in 1999, and his books completely shaped the way I thought about endurance training, hydration, and fueling. But Dr. Noakes' story is also a story of changing your mind when the evidence and your own experience tell you that something isn't working. We talk about his evolution from promoting high-carbohydrate fueling to questioning that approach, his own experience with type 2 diabetes and metabolic health, and the research that changed the way he thinks about endurance performance.We also dive into my own journey with insulin resistance, continuous glucose monitoring, low-carbohydrate endurance training, and what happened when I began experimenting with how I fueled my ultramarathons. This is a conversation about being willing to question what you've been taught, examine your own experience, and keep learning as the science evolves.Thanks as always for listening.Check out Dr. Noakes' foundation here: https://thenoakesfoundation.org/ If you would like to join us, check out the website at doctordulaney.comEmail me with questions at [email protected] water distillers: https://mypurewater.com/?sld=jdulaney. discount code: cleanwaterforsophie
