Dr. Andrew Koutnik | Ketogenic Diets and Athletic Performance | June 21, 2026 | Ep. 71

Dr. Andrew Koutnik breaks down ketogenic diets, metabolic health, athletic performance, and chronic disease prevention using his personal journey and research. Dr. Andrew Koutnik, PhD, is a researcher focused on metabolism, ketogenic diets, cardiometabolic health, and performance. In this conversation, Dr. Koutnik shares how his own health challenges led him to study low-carb and ketogenic nutrition, and how these diets can impact metabolic disease, obesity, diabetes, and cardiovascular risk.He explains the science of ketosis, how ketogenic diets influence fuel use, blood sugar, insulin, and inflammation, and what current evidence shows for endurance and strength performance. Dr. Koutnik also discusses individual variability, why context matters when applying keto to athletes or the general population, and how diet and exercise can be powerful tools to improve public health.The episode explores how nutrition policy, food environment, and incentives shape population-level metabolic health, and what changes could reduce chronic disease burden. Whether you are an athlete, clinician, or someone trying to improve metabolic health, this discussion offers a nuanced, evidence-informed look at ketogenic diets and low-carb strategies.Find Dr. Koutnik:Instagram: https://www.instagram.com/andrewkoutnikphd/X: https://x.com/AKoutnikSite: https://andrewkoutnik.com/YouTube: https://www.youtube.com/channel/UCuBoAR4gzVC5Y0e5raQLPkQKey  topics:Ketogenic diets and athletic performanceImpact of food environment on metabolic healthRole of insulin in disease and healthChapters:00:00 Introduction to Metabolic Health and Personal Journey03:07 Understanding Type 1 Diabetes and Insulin Management05:49 The Role of Food in Metabolic Health08:58 The Impact of Processed Foods on Obesity11:44 The Need for Education and Policy Change14:16 The Role of GLP-1 Drugs in Weight Management17:28 The Importance of Muscle Mass and Nutrition20:07 Transitioning to a Ketogenic Diet23:03 Conclusion and Future Directions25:47 Empowerment Through Dietary Change28:17 The Impact of Low-Carbohydrate Diets31:40 Long-Term Effects of Ketogenic Diets35:06 Balancing Risks and Benefits37:36 Therapeutic Applications of Ketone Bodies42:38 Daily Life and Dietary Practices51:03 Foundational Health Principles52:08 Athletic Performance on a Ketogenic Diet52:40 The Evolution of Carbohydrate Research55:36 Challenging the Carbohydrate Paradigm58:18 The Role of Blood Glucose in Performance01:03:04 Understanding Ketogenic Diet Adaptation01:08:50 Common Mistakes in Low-Carb Diets01:14:52 Future Perspectives on Metabolic Health01:19:51 lifestyle-outro-high-short.wavkeywords:metabolism, ketogenic diet, type 1 diabetes, athletic performance, metabolic health, food environment, insulin, fasting, cardiovascular health, nutrition science, Dr Andrew Koutnik, Andrew Koutnik PhD, Max Helmer The Low Carb Consultant, ketogenic diet, keto for athletes, ketogenic diet athletic performance, metabolic health, low carb diet, chronic disease prevention, insulin resistance, sports performance nutrition, endurance performance keto, ketosis explained, low carb high fat, nutrition policy and health
