The Metabolic Classroom with Dr. Ben Bikman

📢 Ask Dr. Bikman’s Digital Mind (multilingual):https://benbikman.com/ben-bikmans-digital-ai-mind📢 Dr. Bikman’s Community & Coaching Site: https://insuliniq.comTopic:Ben explains how AMPK and mTOR are critical regulators of aging and metabolism, and how their balance can be influenced by diet and lifestyle. Instead of drugs like rapamycin, strategies like carbohydrate restriction and ketosis offer a safer path to optimizing longevity.Summary:In this Metabolic Classroom mini lecture, Dr. Bikman explores two of the most important molecular “switches” that regulate how cells age, grow, and repair themselves: AMPK and mTOR.These pathways operate in a delicate balance—AMPK promotes energy conservation, fat oxidation, and cellular cleanup (autophagy), while mTOR supports cellular growth and protein synthesis. When AMPK is up, mTOR is down, and vice versa.Ben explains how modern lifestyles—especially chronic overnutrition and excess carbohydrate intake—shift this balance toward persistent mTOR activation, which may accelerate aging and metabolic disease. He critiques the growing popularity of rapamycin for longevity, citing its lack of human data and serious side effects, particularly reproductive harm. Instead, he proposes that simple lifestyle strategies—like carbohydrate restriction, ketosis, and supplementation with ketones like BHB—can more safely optimize the AMPK/mTOR balance.He also highlights the importance of ketones as both energy sources and signaling molecules that can activate AMPK and stimulate autophagy. The lecture ends with a clear takeaway: longevity and metabolic health may not require pharmaceuticals, but rather informed choices around diet and lifestyle.References:For complete show notes and references, we invite you to become an Insider subscriber.

When separated from cigarette smoke, it shows surprising anti-inflammatory and neurological potential.Summary:In this Metabolic Classroom mini lecture, Dr. Ben Bikman revisits the molecule nicotine—not as an endorsement to use it, but to explore its distinct effects when separated from harmful compounds in cigarettes.Contrary to popular belief, nicotine alone is not highly addictive; tobacco additives like pyrazines likely amplify the addiction seen in cigarettes. Dr. Bikman details nicotine’s anti-inflammatory properties, particularly through activation of the alpha-7 nicotinic acetylcholine receptor, which may help conditions like ulcerative colitis, sepsis, and arthritis.Ben also explores its complex effects on metabolism—such as increased thermogenesis and fat oxidation—while warning of potential insulin resistance with sustained use.Lastly, he reviews fascinating clinical research suggesting therapeutic potential in conditions like ADHD, autism, Tourette’s syndrome, and even Alzheimer’s, all while emphasizing that nicotine, when separated from cigarette smoke, warrants more open scientific inquiry.References:For complete show notes and references, we invite you to become an Insider subscriber.

This episode shows how BHB acts like a hormone to enhance metabolic health and cellular resilience.Summary:In this episode of the Metabolic Classroom, Dr. Bikman explores the remarkable role of beta-hydroxybutyrate (BHB), the most abundant ketone body, as both a metabolic fuel and a cellular signaling molecule. While traditionally seen as mere backup energy, BHB is now recognized as a potent agent that influences gene expression, reduces inflammation, and protects mitochondrial function.Ben unpacks the dual nature of BHB, describing how it activates specific receptors like GPR109A and FFAR3, modulates immune responses, and directly inhibits the NLRP3 inflammasome, a key player in chronic inflammation. He also highlights how BHB affects epigenetic regulation through HDAC inhibition, enhancing cellular resilience and antioxidant defenses.The lecture concludes by tying these pathways together to show how ketones—whether produced endogenously or taken as supplements—convey a coordinated biological signal of adaptation and protection. This shift in understanding elevates ketones from mere “backup fuel” to central players in metabolic health.NOTE: The information presented is not intended to be a substitute for professional medical advice, diagnosis, or treatment.

📢 Ask Dr. Bikman’s Digital Mind (multilingual): https://benbikman.com/ben-bikmans-digital-ai-mind📢 Dr. Bikman’s Community & Coaching Site, Insulin IQ: https://insuliniq.comIn this lecture, Dr. Ben Bikman explores the misunderstood role of glucagon, insulin’s often-overlooked metabolic counterpart.While insulin encourages fat storage and glucose uptake, glucagon signals the body to mobilize and burn stored energy. Contrary to popular belief, glucagon does not stimulate fat release from adipose tissue in humans. Instead, its fat-burning effects occur primarily in the liver, where it enhances fatty acid oxidation, ketone production, and energy expenditure.Glucagon’s power lies in shifting the metabolic balance through the insulin-to-glucagon ratio—a key determinant of whether the body stores or burns fat. Ben also unpacks the liver's molecular response to glucagon, including activation of mitochondrial fat-burning enzymes and ketone formation. Human studies now confirm that glucagon increases liver fat oxidation, making it a valuable target in new weight-loss drugs.New dual and triple agonist drugs that combine GLP-1 with glucagon receptors show superior weight loss outcomes compared to GLP-1 alone. They not only suppress appetite but also increase metabolic rate, making them potent tools in fighting obesity and fatty liver disease. However, lifestyle strategies like fasting and low-carb diets remain powerful ways to naturally leverage glucagon’s benefits without pharmaceutical intervention.Show Notes/References:For complete show notes and references, we invite you to become an Insider subscriber or member.

Zonulin release is often triggered by dysbiosis and dietary components like gluten and fructose.He also highlights how LPS-induced inflammation impairs insulin signaling and promotes ceramide production, contributing to liver fat accumulation and systemic insulin resistance.Ben offers practical, evidence-based strategies to maintain gut barrier integrity and reduce LPS absorption—these include:- apple cider vinegar- spore-forming probiotics (especially Bacillus subtilis)- prebiotic fibers (like FOS and XOS)- and omega-3-rich foods or supplementsDr. Bikman ends with dietary and lifestyle takeaways to protect gut health and metabolic function.Show Notes/References:For complete show notes and references, we invite you to become an Insider subscriber or member.

📢 To listen ad-free, become an Insider: Ben’s website, https://www.benbikman.com📢 Dr. Bikman’s Community & Coaching Site, Insulin IQ: https://insuliniq.comIn this episode Dr. Bikman explores the concept of “male menopause,” more accurately termed andropause. While women experience a dramatic hormonal drop-off due to the depletion of ovarian follicles, men experience a gradual decline in testosterone, primarily because their testosterone-producing Leydig cells become less efficient with age. This slow reduction begins in the 30s or 40s, and free testosterone (the biologically active form) declines even faster than total testosterone due to increasing levels of sex hormone-binding globulin (SHBG).The lecture delves into the cellular mechanisms behind this decline, focusing on mitochondrial dysfunction and insulin resistance. Because testosterone synthesis starts with cholesterol being transported into the mitochondria, anything that impairs this transport—like declining STAR and TSPO proteins or mitochondrial fragmentation—can reduce testosterone production. Dr. Bikman emphasizes that insulin resistance plays a central role by impairing Leydig cell responsiveness and increasing ceramide production, which worsens mitochondrial fission and dysfunction.Body fat also plays a major role in hormonal health, as it increases aromatase activity, converting testosterone into estradiol. This creates a damaging feedback loop—more fat leads to more estrogen, which suppresses testosterone production, which then leads to more fat gain.Dr. Bikman outlines a set of interventions to break this cycle and support testosterone naturally, including:- Weight loss, especially reducing visceral fat- Resistance training, with caution to avoid overtraining- Cold exposure, done strategically (before, not after exercise)- Sleep hygiene and stress reduction- Limiting alcohol intake- And in some cases, Testosterone Replacement Therapy (TRT), with caveats about fertilityShow Notes/References:For complete show notes and references, we invite you to become an Insider subscriber or member.
