The Metabolic Classroom with Dr. Ben Bikman

• Menopause, Ketones, and Metabolism: A Strategy Explained

  📢 Dr. Bikman’s Community & Coaching Site, Insulin IQ: https://insuliniq.comand/or📢 Become an Insider, Ben’s website: https://www.benbikman.comThis Metabolic Classroom lecture with Dr. Bikman explores how the loss of estradiol during menopause affects five key metabolic systems: the brain, muscles, mitochondria, fat tissue, and inflammation.Each of these systems relies on estradiol for optimal function, and its decline contributes to increased risk for cognitive impairment, muscle loss, reduced mitochondrial function, increased visceral fat, and systemic inflammation.Ketones—particularly beta-hydroxybutyrate (BHB)—can provide a partial compensatory effect in each system. In the brain, BHB supports glucose metabolism, reduces neuroinflammation, and enhances neuroplasticity. In muscles, ketones reduce protein degradation and improve mitochondrial function. At the mitochondrial level, BHB promotes mitochondrial biogenesis and helps reduce oxidative stress through NRF2 activation.The lecture also outlines how ketones affect fat tissue by promoting mitochondrial uncoupling and upregulating thermogenic genes like UCP1. Additionally, BHB helps reduce inflammation by inhibiting the NLRP3 inflammasome. A final section reviews exogenous ketone strategies—salts, esters, acids, and MCTs—as potential tools to support women through menopause-related metabolic changes.Show Notes/References:For complete show notes and references, we invite you to become an Insider subscriber.

• How the MTHFR Gene Affects Our Metabolic Health

  📢 Dr. Bikman’s Community & Coaching Site, Insulin IQ: https://insuliniq.comand/or📢 Become an Insider, Ben’s website: https://www.benbikman.comIn this Metabolic Classroom lecture, Dr. Bikman explores the MTHFR gene and how common mutations can affect overall metabolic health. Ben explains the biochemical role of the MTHFR enzyme in the methylation cycle, its influence on homocysteine levels, and its downstream impact on DNA repair, neurotransmitter synthesis, and detoxification.Ben also discusses how impaired MTHFR function contributes to oxidative stress and insulin resistance, particularly through its effect on the insulin receptor’s expression and membrane insertion. He draws attention to the connection between poor methylation and chronic conditions like fatigue, hormone imbalance, and even cardiovascular risk.The lecture also provides practical strategies to support healthy methylation, including the use of methylated B vitamins (such as methylfolate and methylcobalamin), food sources like liver, and appropriate cooking methods for plant-based folate. His emphasis throughout is on using targeted nutrition and lifestyle choices to compensate for genetic vulnerabilities.Show Notes/References:For complete show notes and references, we invite you to become an Insider subscriber.

• Creatine Demystified: Brain, Muscle & Metabolic Benefits

  📢 Dr. Bikman’s Coaching Site, Insulin IQ: https://insuliniq.comand/or📢 Become an Insider, Ben’s website: https://www.benbikman.comIn this Metabolic Classroom lecture, Dr. Bikman breaks down the true nature and benefits of creatine—a molecule often misunderstood as merely a muscle-building supplement. Creatine plays a critical role in cellular energy production by helping regenerate ATP, especially in high-energy tissues like skeletal muscle and the brain. While our bodies produce creatine endogenously, supplementation can significantly enhance its availability and effects.Ben discusses how creatine has been shown to improve physical performance, support brain health, and even influence glucose metabolism. It helps increase strength, power output, and recovery during resistance training. In the brain, it supports cognitive function and may protect against neurodegenerative conditions. For individuals with insulin resistance or type 2 diabetes, creatine can improve glucose uptake by enhancing GLUT4 translocation.He also addresses common myths—especially the misconception that creatine damages the kidneys. Ben emphasizes that while creatinine levels may rise with supplementation, this does not indicate harm in healthy individuals. He further explains the potential gene-level benefits of creatine, such as improved expression of IGF-1 and myogenic regulatory factors related to muscle health.The lecture concludes with practical advice on dosing and choosing the right form of creatine, noting that creatine monohydrate remains the most effective and well-studied option. Ben encourages its use not just for athletes but for anyone looking to support muscle, brain, or metabolic health.Show Notes/References:For complete show notes and references, we invite you to become an Insider subscriber.

• Can Nattokinase Improve Heart & Metabolic Health?

  📢 Dr. Bikman’s Coaching Site, Insulin IQ: https://insuliniq.comand/or📢 Become an Insider, Ben’s website: https://www.benbikman.comIn this Metabolic Classroom lecture, Dr. Bikman dives into the science behind nattokinase, an enzyme derived from natto—a fermented soybean staple in Japan. Nattokinase has gained attention for its cardiovascular benefits, especially its ability to dissolve blood clots. Ben explains the enzyme’s key role in degrading fibrin, the primary structural protein in clots, and how it stimulates the body’s own clot-dissolving pathway by activating plasminogen. He compares its action to pharmaceutical blood thinners like Warfarin but notes nattokinase may work without the same bleeding risks.Beyond clot dissolution, Ben explores nattokinase’s effects on atherosclerosis. He shares clinical trial results where nattokinase reduced plaque size and arterial wall thickness, even outperforming statins in some metrics. The enzyme also appears to improve lipid profiles, including lowering triglycerides and slightly boosting HDL. Though Ben remains skeptical of LDL as a reliable heart disease predictor, these lipid changes are seen as beneficial.The lecture also touches on how nattokinase might support metabolic health. Some human and animal studies suggest the enzyme improves insulin sensitivity, possibly by activating lipoprotein lipase and hormone-sensitive lipase, both involved in fat metabolism. Rodent studies also hint at a role in reducing lipid peroxidation, potentially decreasing levels of oxidized LDL, a strong predictor of heart disease. However, Ben notes more human research is needed to confirm these findings.Dr. Bikman ends the lecture by acknowledging the limitations of current nattokinase research, such as small study sizes, inconsistent dosing, and questions around supplement bioavailability. Despite these gaps, he finds the cardiovascular evidence promising and suggests those interested might consider trying natto—the whole food source—rather than a supplement. While not a magic bullet, nattokinase offers compelling support for vascular health and metabolic resilience.Show Notes/References:For complete show notes and references, we invite you to become an Insider subscriber.

• The China Study Revisited - Science vs. Storytelling

  📢 Dr. Bikman’s Coaching Site, Insulin IQ: https://insuliniq.comand/or📢 Become an Insider, Ben’s website: https://www.benbikman.comIn this episode of The Metabolic Classroom, Dr. Bikman critically examines the claims made in The China Study, a popular book advocating for a plant-based diet based on correlational data from the China-Cornell-Oxford Project. While the book suggests that animal protein causes cancer and chronic disease, Ben emphasizes that correlation is not causation and points out that many of the study’s conclusions are misleading or unsupported by the raw data.For example, some regions with higher meat consumption actually had lower cancer mortality, and wheat flour consumption showed a stronger correlation with heart disease than meat intake.He also scrutinizes the rat experiments used to bolster the study’s conclusions. These studies involved pairing a powerful carcinogen with isolated casein (a dairy protein), resulting in cancer growth. However, Ben highlights that whole dairy, including fats like CLA and butyrate, may actually protect against cancer. He explains how isolating one protein and ignoring other nutrients misrepresents the effects of real, whole food consumption.Ben then shifts to mechanisms and dissects the mTOR pathway, often cited in arguments against animal protein. He presents data showing that insulin—not leucine—is a much more potent and sustained activator of mTOR. This undermines the idea that animal protein is uniquely harmful and suggests that refined carbohydrates, which spike insulin, are more concerning in cancer development.In conclusion, Dr. Bikman encourages viewers not to fear animal protein, especially when consumed with its natural fats in whole foods. He urges people to scrutinize bold dietary claims and recognize that refined carbs, not protein, are more consistently implicated in disease. While The China Study may have popularized plant-based eating, its scientific foundation is far less solid than many assume.Show Notes/References:For complete show notes and references, we invite you to become an Insider subscriber.
