We all know there are universal rules to follow when it comes to eating a healthy diet, but personalization should be at the top of the list. While we have a lot in common as human beings and there are certain nutritional guidelines applicable to all of us, we’re different in important ways too. We have different genetics, constitutions, health status, activity levels, lifestyles, and goals, and all of these factors determine what an optimal diet is for each of us. On today’s Broken Brain Podcast, our host, Dhru, talks to Chris Kresser, the CEO of Kresser Institute for Functional & Evolutionary Medicine, the co-director of the California Center for Functional Medicine, the creator of ChrisKresser.com, and the New York Times bestselling author of The Paleo Cure. He is known for his in-depth research uncovering myths and misconceptions in modern medicine and providing natural health solutions with proven results. Chris was named one of the 100 most influential people in health and fitness by Greatist.com, and his blog is one of the top-ranked natural health websites in the world. He recently launched Kresser Institute, an organization dedicated to reinventing healthcare and reversing chronic disease by training healthcare practitioners in Functional and evolutionary medicine. In this episode, Dhru and Chris talk about an ancestral diet and lifestyle and the potential for preventing chronic disease. They discuss how to personalize your diet to fit your lifestyle, body type, genetic blueprint, individual needs, and specific health conditions. They also talk about the benefits of intermittent fasting and how you can determine the right approach for you, as well as when it is not recommended. In this episode, we dive into:-Why one specific diet is not right for everyone (3:08) -How to personalize your diet (6:12) -A current diet trend that might not actually be healthy (9:26)-The truth about the bioavailability of nutrients from plant-based foods (18:03) -What we can learn from the ancestral diet (34:35)-The biggest mistake in nutritional science (38:21)-A good starting place to determine your ideal macronutrient ratio (40:47)  -The most effective approach to intermittent fasting (45:03) -Who shouldn’t do intermittent fasting (50:38)-When lab testing is necessary (54:18)-Chris’s take on the latest health trends (1:07:17)-Learn more about Chris and his work (1:13:30) For more on Chris Kresser, be sure to follow him on Instagram @chriskresser, on Facebook @chriskresserlac, on Twitter @chriskresser, and on YouTube @chriskresser.
