Ben highlights how lifestyle changes, not supplements, offer the most effective way to restore balance and protect metabolic health.</p><br><p>Summary:</p><p>In this mini lecture, Dr. Bikman explains the critical role of the NAD⁺ to NADH ratio in cellular metabolism and its link to insulin resistance.</p><br><p>NAD⁺ and NADH function like a cellular battery, cycling between charged and uncharged states to fuel energy production. However, when this balance tips toward excess NADH—as happens with chronic high glucose intake, aging, alcohol consumption, or inactivity—metabolic dysfunction follows.</p><br><p>Ben walks through the mechanisms by which a low NAD⁺/NADH ratio disrupts insulin signaling, including suppression of mitochondrial function, accumulation of harmful lipid intermediates (like ceramides), and increased oxidative stress. He also introduces the concept of "reductive stress," a pseudo-hypoxic state that cells enter when overwhelmed by glucose, leading to long-term damage and perpetuation of insulin resistance.</p><br><p>To improve this ratio and support better metabolic health, Dr. Bikman recommends five main lifestyle strategies: restricting refined carbohydrates, exercising regularly, practicing time-restricted eating, optimizing sleep, and reducing or eliminating alcohol.</p><br><p>While NAD⁺-boosting supplements like nicotinamide riboside show promise in animal models, their human effects remain limited—highlighting that lifestyle changes still provide the most reliable path to metabolic improvement.</p><br><p>References:</p><p>For complete show notes and references, we invite you to become an Insider subscriber.
