  • How Autophagy Protects Your Cells and Boosts Longevity
    In this Metabolic Classroom lecture, Dr. Bikman delves into the fascinating metabolic process of autophagy, the body’s natural recycling system that maintains cellular health by breaking down and reusing damaged components.Ben explains how autophagy is essential for replacing malfunctioning organelles and proteins, thereby preventing diseases such as neurodegenerative disorders, cardiovascular conditions, and even some cancers. Autophagy also plays a crucial role in energy production during nutrient deprivation, highlighting its importance for survival and optimal cellular function.Dr. Bikman also discusses the relationship between autophagy and metabolic health, emphasizing how impaired autophagic activity in adipose tissue contributes to inflammation and insulin resistance in obesity. He explores its role in longevity, citing evidence that enhanced autophagy can improve health span and lifespan in animal studies.Additionally, Ben examines how factors like insulin, nutrient availability, and diets such as ketogenic diets regulate autophagy, with ketones having a direct effect on boosting this process.Throughout the lecture, Dr. Bikman underscores the need for balance in autophagy, warning against excessive or constant activation, whether through pharmacological means like rapamycin or mismanaged dietary habits, advocating instead for natural regulation via nutrient signals.Show Notes/References:For complete show notes and references referred to in this episode, we invite you to become a Ben Bikman Insider subscriber.

  • The Metabolic Consequences of Poor Sleep
    Learn more about becoming an Insider on our website: https://www.benbikman.comDr. Benjamin Bikman delves into the profound relationship between sleep and metabolic health, emphasizing the critical role sleep plays in maintaining insulin sensitivity and overall metabolic function.Ben explains that deep sleep is a restorative phase during which the body repairs cells, regulates hormones, and improves insulin sensitivity. Poor sleep, however, disrupts these vital processes, leading to hormonal imbalances that elevate cortisol levels and reduce melatonin production.Elevated cortisol, a stress hormone, promotes gluconeogenesis and insulin resistance, while insufficient melatonin—a hormone essential for regulating sleep—negatively impacts insulin sensitivity and glucose metabolism. This disruption creates a cycle of metabolic dysfunction, increasing the risk of conditions like type 2 diabetes and obesity.Dr. Bikman highlights actionable strategies to improve both sleep and metabolic health. He stresses the importance of avoiding high-glycemic meals before bed, minimizing exposure to blue light from screens, and maintaining consistent sleep schedules.He also discusses how ketones, especially in athletes after intense exercise, have been shown to improve sleep efficiency and REM sleep duration.For individuals struggling with sleep, Dr. Bikman explores the potential benefits of melatonin supplementation and exogenous ketones, underscoring the need for personalized approaches. By addressing evening habits and understanding the hormonal interplay between sleep and metabolism, individuals can take meaningful steps to enhance both sleep quality and metabolic health.This episode of The Metabolic Classroom provides valuable insights into how optimizing sleep can significantly improve overall well-being.Timestamps:(00:45) – Introduction to Sleep and Metabolic Health(01:22) – Why Sleep is Essential for Insulin Sensitivity(04:20) – How Cortisol Disrupts Sleep and Metabolism(08:10) – The Unexpected Role of Melatonin in Metabolism(19:35) – How Late-Night Eating and Blue Light Harm Sleep(23:40) – Can Exogenous Ketones Improve Sleep Quality?(28:20) – Practical Tips for Better Sleep and Metabolic Health Hosted on Acast.

  • The Unexpected Link Between Salt Regulating Hormones and Metabolic Health
    We sincerely apologize! During the livestream recording, we experienced some technical difficulties between 07:15 to 08:50. Thanks for your patience and understanding.Learn more about becoming an Insider on our website: https://www.benbikman.comDuring The Metabolic Classroom lecture this week, Dr. Bikman dives into the intricate relationship between salt- and water-regulating hormones and metabolic health.Starting with a discussion of the renin-angiotensin-aldosterone system (RAAS), he explains how hormones like angiotensin II, aldosterone, and antidiuretic hormone (ADH) are not only critical for regulating blood pressure but also significantly impact insulin sensitivity and fat cell dynamics. Angiotensin II promotes insulin resistance by increasing ceramide production, which blocks insulin signaling, while also enlarging fat cells and inhibiting their breakdown. Similarly, aldosterone exacerbates insulin resistance by enhancing ceramide levels and promotes both the growth and multiplication of fat cells. ADH complements these effects, particularly by inhibiting fat breakdown through its action on specific receptors.Ben emphasizes the counterintuitive finding that salt restriction, often prescribed to manage hypertension, can worsen insulin resistance, particularly in individuals with metabolic vulnerabilities. Studies highlight that reducing salt intake leads to increased fasting insulin levels, impaired glucose metabolism, and unfavorable lipid changes, such as reduced HDL cholesterol. Additionally, he warns that dehydration, much like salt restriction, activates these same hormonal pathways, compounding their metabolic effects.Dr. Bikman concludes with a reminder that interventions aimed at improving blood pressure should consider their broader metabolic implications, particularly for individuals predisposed to insulin resistance.Show Notes/References:For complete show notes and references referred to in this episode, we invite you to become a Ben Bikman Insider subscriber.

  • Hypertension Medications and Metabolic Health
    Learn more about becoming an Insider on our website: https://www.benbikman.comThis week in The Metabolic Classroom lecture, Ben focuses on the relationship between hypertension medications and metabolic health, providing a critical examination of their mechanisms and metabolic implications.He begins by highlighting the role of insulin resistance as a common root cause of both hypertension and metabolic disorders. Ben explains that while hypertension medications such as diuretics, beta blockers, ACE inhibitors, ARBs, and calcium channel blockers are often prescribed, they each have unique effects on insulin sensitivity and glucose metabolism, which can either mitigate or exacerbate metabolic dysfunction. Notably, some classes of these medications, like ARBs, may improve insulin sensitivity, while others, like beta blockers and diuretics, can impair it, leading to heightened risks for type 2 diabetes.Ben underscores the importance of addressing the root causes of hypertension—namely, insulin resistance—through lifestyle interventions like low-carbohydrate diets and fasting, which improve both blood pressure and metabolic health. He emphasizes the need for personalized treatment plans that consider the metabolic side effects of medications, advocating for strategies that tackle insulin resistance as a primary approach to improving overall health.Show Notes/References:For complete show notes and references referred to in this episode, we invite you to become a Ben Bikman “Insider” subscriber.

  • Thyroid Health and Low-Carb Diets: What Lower T3 Really Means
    This week in The Metabolic Classroom, Ben explores the effects of a ketogenic diet on thyroid function, addressing concerns that lower thyroid hormone levels observed during the diet may indicate dysfunction.Dr. Bikman begins by explaining the hypothalamic-pituitary-thyroid (HPT) axis, a regulatory system that controls thyroid hormone production. The thyroid gland produces two primary hormones, T3 (triiodothyronine) and T4 (thyroxine), with T3 being the active form that influences metabolic processes. He emphasizes the concept of negative feedback within the HPT axis, explaining that normal TSH levels generally indicate a well-functioning thyroid, even if T3 levels are lower.Ben also reviews a commonly cited study that observed decreased T3 levels in individuals following a ketogenic diet. Despite the drop in T3, TSH levels remained normal, suggesting that the thyroid gland was not damaged but rather adapting to reduced metabolic demand. He introduces two key explanations: improved thyroid hormone sensitivity and reduced glucose metabolism. Improved sensitivity means that lower levels of T3 are sufficient to maintain metabolic functions, while reduced glucose consumption on a ketogenic diet lessens the body’s need for thyroid hormone to regulate glucose uptake.The classroom lecture then delves into the concept of thyroid hormone resistance, a condition linked to metabolic disorders like obesity and type 2 diabetes. Dr. Bikman references studies showing that thyroid resistance is real and measurable, often associated with elevated TSH and thyroid hormones in individuals with metabolic syndrome. He speculates that a ketogenic diet may enhance thyroid sensitivity in these individuals, reducing the need for higher T3 levels.In conclusion, Dr. Bikman reassures those on a ketogenic diet that lower T3 levels do not necessarily indicate harm. If TSH levels are normal and no symptoms of hypothyroidism are present, the changes may reflect a healthy adaptation to the metabolic state induced by the diet.Show Notes/References:For complete show notes and references referred to in this episode, we invite you to become a Ben Bikman “Insider” subscriber.
