703: Keto Works… But Not the Way You Think | Dr. Andrew Koutnik

In this comprehensive three-part episode of The Jesse Chappus Show, Dr. Andrew Koutnik, a metabolic health scientist and long-term adherent of the ketogenic diet, dismantles common misconceptions and provides a science-backed deep dive into the true nature of keto. He traces the diet’s 200-year history as a therapeutic intervention for diabetes, obesity, and neurological conditions, emphasizing that it is not a modern fad but a well-established metabolic strategy. Dr. Koutnik explains how reducing carbohydrates triggers a fundamental metabolic shift—from glucose to fat and ketone-based fuel—reducing insulin levels and enhancing fat oxidation, which is key to reversing metabolic dysfunction. He clarifies that calories and insulin still matter, even on keto, and that adding excess fat to a high-carb diet leads to weight gain, while fat on a low-carb foundation supports sustainability. The episode covers the physiological changes during adaptation, including water weight loss and the keto flu, and highlights the brain’s preference for ketones and lactate during energy deficits. Practical guidance is woven throughout, including the importance of prioritizing protein (1g per pound of body weight), strategic use of exogenous ketones, and the role of fasting and exercise in metabolic health. Dr. Koutnik also discusses the value of extended fasting (72+ hours) for resetting hunger cues and the potential effectiveness of radical approaches like the carnivore diet for those who struggle with traditional eating patterns. He underscores that success hinges on preparation, sodium management, and environmental design—such as removing trigger foods and reformulating favorites with natural sweeteners like stevia and allulose—to ensure long-term adherence and enjoyment. Ultimately, the episode positions keto not as a restrictive diet but as a sustainable, empowering lifestyle rooted in metabolic science and psychological readiness.
