About the expert
Focus: Ketogenic diet for diabetes and athletic performance, calibrated against the carbohydrate-insulin model of metabolic disease
Andrew Koutnik is a metabolic researcher who lives with type 1 diabetes and studies the use of ketogenic diets in athletic performance and clinical metabolic disease. He has published randomized controlled trials in trained athletes that challenge the high-carbohydrate orthodoxy in sports nutrition.
Why this matters
Metabolic researcher focused on ketogenic diets and type 1/type 2 diabetes. Koutnik brings the rare combination of academic rigor and lived experience — he manages his own type 1 diabetes using metabolic interventions. His work is grounded in peer-reviewed sports-nutrition and clinical-metabolic research, and he is generally cautious about extending claims beyond their evidence base.
