Today I feel privileged to connect with the legendary Mark Sisson, the New York Times bestselling author of The Keto Reset Diet and bestselling book, The Primal Blueprint! Mark has been integral in turbo-charging the growth of the Primal Paleo movement. He is a prolific writer, blogger, and the founder of Primal Kitchen and Primal Nutrition. Our body’s ability to supply the cells with energy is critical to our lives. In all his work, which spans decades, Mark emphasizes the importance of metabolic health, which means that every cell in the body gets supplied with enough energy to function optimally. Metabolic flexibility is the body’s ability to extract energy from multiple sources, including fat stored in the body, and access energy from ketones to fuel the brain. In this episode, Mark and I dive into metabolic health and flexibility, nutritional dogmatism, disordered eating and extremes, and the misguidedness of the "calories in, calories out" approach. We discuss food scarcity, intermittent fasting, impulse control, and mindset, and Mark also shares how he has managed to have a healthy, happy, and well-adjusted family despite his success.   I hope you enjoy our conversation and gain a lot from listening to it! Stay tuned for more! IN THIS EPISODE YOU WILL LEARN What does metabolic health look like day-to-day? Mark explains how metabolic flexibility empowers people. Mark explains why we tend to over-eat from an evolutionary perspective. Most Americans are over-fed and under-nourished. Ideally, we need to figure out a strategy for eating as little as possible and staying satiated while building and maintaining muscle mass and having all the energy we need. You will get sarcopenia if you do not actively work against it.  What does it take to maintain your thyroid health? It is much easier to avoid over-eating when you become aware of being satiated. Building lean muscle mass is critical. It is crucial to understand that men and women have different nutritional requirements. Why is the “calories in, calories out” approach to weight loss misguided? Mark explains why he advocates for a more flexible approach to food choices. Mark shares his secret to cultivating a healthy and happy personal life alongside his professional life.
