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.
