After 12 weeks, anthropometric and body composition measurements revealed a significant reduction of body weight (− 9.43 kg), BMI (− 3.35), FBM (8.29 kg) and VAT. There was a significant, slightly decrease of LBM. A significant decrease in glucose and insulin blood levels were observed, together with a significant improvement of HOMA-IR. A significant decrease of triglycerides, total cholesterol and LDL were observed along with a rise in HDL levels. The LH/FSH ratio, LH total and free testosterone, and DHEAS blood levels were also significantly reduced. Estradiol, progesterone and SHBG increased. The Ferriman Gallwey Score was slightly, although not significantly, reduced.

Our results suggest that a KD may be considered as a valuable non pharmacological treatment for PCOS. Longer treatment periods should be tested to verify the effect of a KD on the dermatological aspects of PCOS.

The video is an interview with Sally K. Norton, an expert on oxalates and their impact on health. Norton discusses the basics of oxalates, their sources, and the potential health issues they can cause, including kidney stones, arthritis, and mitochondrial damage. She highlights high-oxalate foods like spinach, nuts, and sweet potatoes, and explains that a low-oxalate diet can help alleviate symptoms. Norton also addresses common misconceptions, such as the belief that certain bacteria can heal the gut and eliminate oxalate issues.

Summary

In this extensive and candid conversation between Dr. Eric Westman and Bart K, a former health science professor turned influential keto and carnivore diet advocate, the discussion primarily focuses on the flaws in nutritional epidemiology, the misinformation surrounding low-carb and ketogenic diets, and the challenges of implementing evidence-based nutritional advice in modern medicine. Bart K shares his journey from academia, where his radical views on carbohydrate requirements and fiber were met with resistance, to becoming an online influencer educating the public about metabolic health and nutritional myths. He underscores the fundamental flaws in nutritional epidemiology studies, particularly their reliance on self-reported dietary data and inappropriate statistical adjustments, which often lead to misleading conclusions about diet and health.

The dialogue also tackles the prevailing misconceptions about low-carb diets, such as the unfounded fear that high fat intake causes heart disease or cancer. Both speakers emphasize that type 2 diabetes is fundamentally about chronically elevated blood glucose, not simply insulin resistance or deficiency, and criticize the medical system’s reliance on pharmaceutical interventions over dietary solutions. The conversation highlights the challenges physicians face in promoting nutrition due to systemic constraints, commercial interests, and professional risks.

Bart K expresses optimism about grassroots changes driven by informed individuals and emerging research, including the growing acceptance of ketogenic therapies in cardiology and the rise of carnivore diet proponents. However, he acknowledges the difficulty of conducting long-term, rigorous clinical trials on diets due to ethical and practical constraints. The discussion concludes with a call for critical thinking, individual experimentation, and skepticism of authority in nutrition science, encouraging people to explore low-carb or carnivore diets gradually while monitoring their own health outcomes.

Highlights

  • 🥩 Bart K advocates for a 100% carnivore diet as the species-appropriate human diet.
  • 📉 Nutritional epidemiology is deeply flawed due to reliance on self-reported data and improper statistical adjustments.
  • 🔬 Association does not imply causation; many diet-health claims are based on misleading correlations.
  • 💊 The medical system favors drug interventions over dietary changes due to financial incentives.
  • 🍽️ Type 2 diabetes is fundamentally about elevated blood glucose, not just insulin resistance.
  • 📊 True scientific causality in nutrition is hard to establish due to ethical and practical research constraints.
  • 🌱 Emerging research and grassroots movements are fostering new perspectives on keto, carnivore, and metabolic health.

Key Insights

  • 🔍 Flaws in Nutritional Epidemiology: In-depth Analysis
    Bart K explains that nutritional epidemiology studies are inherently unreliable because they rely on infrequent, self-reported dietary surveys that are inaccurate by nature. These studies often use complex statistical techniques like multivariate regression that violate key assumptions such as independence of variables, leading to invalid conclusions. For example, adjusting for age while studying long-term diet-related disease incidence creates collinearity, making the data mathematically invalid. This calls into question much of the dietary advice based on such studies, including the demonization of saturated fat and meat consumption.

  • 🧪 Association Does Not Equal Causation: Critical Thinking Needed
    Both experts stress that a high correlation between a dietary factor and disease does not prove that one causes the other. They illustrate this with humorous examples (ice cream sales and sunburn incidence) to highlight how such data can be misleading. This misunderstanding fuels pseudoscientific claims in nutrition and public health. The takeaway is that consumers and practitioners must critically evaluate scientific claims and not accept correlations as proof.

  • 🍏 Misconceptions About Low-Carb and Keto Diets
    The conversation debunks common fears that low-carb or ketogenic diets cause heart disease or cancer. Bart K and Dr. Westman emphasize that these diets often reduce hunger and promote steady weight loss, making them sustainable and effective. They also argue that insulin resistance is not the root cause of type 2 diabetes but rather a protective response to chronic hyperglycemia caused by excessive carbohydrate intake. Thus, reducing carbs is a logical and effective intervention.

  • 💊 Pharmaceutical Industry vs. Nutrition: Systemic Challenges
    There is a critical view of the medical establishment’s preference for drug treatments over dietary interventions, largely driven by financial incentives. Drugs like insulin or SGLT2 inhibitors are prescribed widely for diabetes and heart failure, despite the potential for dietary approaches to achieve similar or better results without adverse side effects. This systemic bias inhibits the adoption of nutritional therapies even when evidence supports their efficacy.

  • 📈 The Role of Ketones and Emerging Research in Cardiovascular Health
    Interestingly, new research in cardiology is exploring ketones as a therapeutic agent for heart failure, often via drugs that induce ketosis (e.g., SGLT2 inhibitors). This paradoxically introduces ketones into mainstream medicine, though through pharmaceutical routes rather than diet. This development might pave the way for broader acceptance of ketogenic diets in clinical practice, but the financial motivations behind drug promotion remain a barrier.

  • 🥩 Carnivore Diet as the Ultimate Species-Specific Diet
    Bart K strongly advocates the carnivore diet, claiming it to be the natural, optimal diet for humans based on anthropological evidence such as nitrogen isotope analysis of ancient human remains showing high animal product consumption pre-agriculture. Despite skepticism and lack of long-term randomized controlled trials (RCTs), he asserts that the carnivore diet has solid scientific and clinical foundations and is gaining traction, evidenced by new educational courses and patient interest.

  • 🧬 Challenges in Conducting Long-Term Nutrition Trials
    Both speakers agree that high-quality, long-term RCTs to definitively prove causality in nutrition are nearly impossible due to ethical, practical, and financial constraints. Human subjects cannot be locked in controlled environments for decades, and dietary adherence is difficult to monitor objectively over long periods. Consequently, much of nutrition science remains observational or mechanistic, and individuals must rely on personal experimentation and biomarker monitoring.

  • 🧠 The Need for Critical Thinking and Personal Experimentation
    Ultimately, the dialogue encourages moving beyond blind trust in authorities, government guidelines, or even academic consensus. Instead, individuals should engage in personal experimentation, using modern tools like continuous glucose monitors, artery ultrasounds, and lipid profiles to assess their health responses to different diets. This pragmatic approach empowers people to find what works best for their unique biology and circumstances.

  • 🛑 Critique of Medical Education and Practice on Nutrition
    Bart K criticizes medical training for lacking robust nutrition education, leaving physicians ill-equipped to counsel patients on diet. Physicians are often “trained monkey grinders,” bound by professional norms and punitive licensing boards to avoid deviating from established dogma. This institutional inertia suppresses innovation and honest dialogue about effective dietary therapies, forcing patients to seek alternative sources of information.

  • 🌿 Grassroots Movements and New Generations of Doctors
    Despite systemic obstacles, there is optimism about change driven by younger physicians and researchers independently exploring ketogenic and carnivore diets. The growing grassroots interest, online education, and patient-driven demand are gradually challenging the status quo. This bottom-up momentum may eventually influence mainstream medicine and public health policy.

Conclusion

This conversation offers a profound critique of the current state of nutritional science and medicine, revealing the deep flaws in epidemiological research, the misinformation surrounding diet and chronic disease, and the systemic barriers to adopting effective dietary therapies like low-carb and carnivore diets. Bart K and Dr. Westman advocate for a return to rigorous scientific principles, critical thinking, and personal experimentation, while highlighting the growing momentum of grassroots movements and emerging research validating metabolic health interventions. Their message is clear: individuals should be empowered to explore dietary approaches grounded in evolutionary biology and clinical outcomes rather than flawed statistics and commercial interests.
