The Metabolic Classroom with Dr. Ben Bikman

• Acne & Insulin Resistance: Why Your Diet Matters More Than You Think

  Learn more about becoming an Insider: https://www.benbikman.comIn this week’s lecture, Dr. Bikman explores the metabolic origins of acne, challenging the conventional view that acne is purely a skin issue. While acne is often attributed to excess oil production, clogged pores, bacteria, and inflammation, Ben highlights how metabolic factors—especially insulin—play a significant role.Insulin directly stimulates sebaceous glands, increasing oil production, and also triggers the release of androgens (such as testosterone), further worsening acne. Additionally, insulin resistance promotes inflammation and hyperkeratinization, both of which contribute to acne severity.He explains that puberty naturally induces a state of insulin resistance, which helps drive growth and development. However, when combined with modern high-carbohydrate diets, this physiological insulin resistance can be exacerbated, leading to severe acne in some teenagers. He also discusses the role of insulin-like growth factor 1 (IGF-1), which is stimulated by high insulin levels and is known to increase sebum production and accelerate skin cell turnover, worsening acne conditions.Ben then presents compelling research on metabolic-based acne treatments, including the use of metformin, an insulin-sensitizing drug that has shown promise in reducing acne, particularly in conditions like PCOS. He also highlights dietary interventions, particularly low-carbohydrate and ketogenic diets, which have been found to significantly reduce acne severity by lowering insulin and improving skin health. One study found that young women on a ketogenic diet saw a 33% reduction in acne severity and a 50% improvement in skin quality within just 45 days.He concludes that acne is not just a cosmetic issue but a metabolic condition that can be managed through dietary and lifestyle changes. While conventional acne treatments address symptoms, tackling insulin resistance through proper nutrition provides a long-term solution. He encourages those struggling with acne to focus on cutting out refined carbohydrates, prioritizing protein, and embracing healthy fats to regulate insulin levels and improve skin health.

• How ADHD Medications Affect Fat Burning, Insulin & Brain Health

  Learn more about becoming an Insider: https://www.benbikman.comIn this week’s episode of the Metabolic Classroom lectures, Dr. Ben Bikman explores the metabolic impact of ADHD medications and whether ADHD itself has metabolic roots.Ben explains how stimulant medications (like Adderall and Ritalin) primarily work by increasing dopamine and norepinephrine, enhancing focus but also suppressing appetite and stimulating fat breakdown. This can lead to weight loss but may also contribute to binge eating episodes when the medication wears off. Non-stimulant ADHD medications (like Atomoxetine and Guanfacine) affect metabolism in different ways—some subtly improve insulin sensitivity, while others reduce fat breakdown, potentially leading to weight gain.Beyond medication, Dr. Bikman discusses ADHD as a possible metabolic disorder. Studies show that individuals with ADHD often have reduced glucose metabolism in the prefrontal cortex, the brain region responsible for attention and impulse control. He highlights research linking chronic sugar consumption to dopamine imbalances and brain energy instability, suggesting that modern dietary habits may be worsening ADHD symptoms.One potential solution? Ketones as an alternative brain fuel. Dr. Bikman shares research on the ketogenic diet as a therapy for ADHD, similar to its use in epilepsy and Alzheimer’s disease. By shifting the brain’s energy source from glucose to ketones, individuals may experience more stable brain function and improved focus. He concludes that ADHD may not just be a neurological condition—it could also be a metabolic issue, and targeting brain metabolism may offer new treatment possibilities.Show Notes/References:For complete show notes and references referred to in this episode, we invite you to become a Ben Bikman Insider subscriber.

• GLP-1 Medications Explained: Benefits, Risks, and What You Need to Know

  Learn more about becoming an Insider: https://www.benbikman.comDr. Bikman’s Metabolic Classroom lecture this week explores the physiological role and implications of GLP-1 (glucagon-like peptide-1) and the GLP-1 receptor agonist drugs used for type 2 diabetes management and weight loss.Ben begins by explaining GLP-1 as a hormone produced in the intestines in response to food. It plays a vital role in slowing gastric emptying, suppressing glucagon, and regulating appetite by signaling fullness to the brain. These mechanisms contribute to its effects on stabilizing blood sugar and enhancing insulin sensitivity.He then delves into GLP-1 receptor agonists, drugs that mimic GLP-1’s actions, including semaglutide, liraglutide, and others marketed under brand names like Ozempic and Wegovy. These medications have gained fame for their weight loss efficacy, often leading to reductions in body weight by 15% or more.However, Ben emphasizes that weight loss involves not only fat but also lean mass, raising concerns about muscle loss and metabolic health. Additionally, he discusses the medications’ side effects, including depression, anhedonia, and potential long-term complications like fat cell development and gallstones.The lecture also addresses the diminishing returns of these drugs over time, noting that their efficacy in reducing cravings and improving eating control tends to wane after prolonged use. Dr. Bikman highlights that education on healthy eating and resistance training is crucial for maintaining health outcomes, as reliance solely on medication can lead to unintended consequences, such as increased fat regain after discontinuation.Ben concludes by stressing the importance of combining these drugs with a low-carb diet and resistance training to minimize muscle loss and optimize long-term outcomes. He encourages using the lowest effective dose and underscores the need for lifestyle changes to complement pharmacological interventions.Show Notes/References:For complete show notes and references referred to in this episode, we invite you to become a Ben Bikman Insider subscriber.

• Metabolic Surgeries: How Bariatric Procedures Work, Their Benefits and Risks

  Learn more about becoming an Insider: https://www.benbikman.comThis week, Dr. Bikman’s lecture focuses on metabolic surgeries (also called bariatric surgeries), their mechanisms, and their impacts on weight loss and metabolic health.Ben begins by explaining the qualifications for these surgeries, which often serve as a last resort for individuals with severe obesity or comorbidities like type 2 diabetes. Common qualifications include a BMI of 40 or higher, or lower BMIs with conditions like hypertension or diabetes. These surgeries aim to address obesity and related health complications when traditional methods, like diet and exercise, fail.Dr. Bikman describes four primary types of metabolic surgeries: Roux-en-Y gastric bypass, sleeve gastrectomy, biliopancreatic diversion with duodenal switch, and adjustable gastric banding. He explains their procedures, including how they alter digestion, absorption, and stomach size, leading to weight loss through restriction and malabsorption. These surgeries also bring significant hormonal changes, such as increases in GLP-1 and reductions in ghrelin (hunger hormone), contributing to satiety and metabolic improvements.While these surgeries can dramatically improve insulin sensitivity, reduce glucagon levels, and improve conditions like type 2 diabetes, they come with risks. Nutrient deficiencies, surgical complications, dumping syndrome, and weight regain are significant concerns. Younger patients are particularly prone to weight regain, especially if they don’t adopt sustainable eating habits. Dr. Bikman emphasizes the need for education on managing macronutrients and maintaining long-term behavioral changes.Ben concludes that metabolic surgeries can be a valuable tool for those with severe obesity and related complications. However, he warns of their limitations and advocates for coupling them with lifestyle changes to optimize long-term success.Show Notes/References:For complete show notes and references referred to in this episode, we invite you to become a Ben Bikman Insider subscriber.

• 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.
