Michael Davidson is a world-renowned cardiologist, lipidologist, and the founding CEO of NewAmsterdam Pharma. He begins this episode by sharing how his family history shaped his interest in lipidology and primary prevention. He explains why prevention should focus on causal drivers of disease rather than near-term risk and examines the causal relationship between LDL and atherosclerotic cardiovascular disease. Michael then traces the complicated history of CETP inhibitors—from the original rationale that raising HDL would reduce cardiovascular risk to the failures of torcetrapib, dalcetrapib, and evacetrapib—and explains how lessons from these trials ultimately led to the development of obicetrapib. He reviews the phase 2 and phase 3 trials of obicetrapib, its effects on LDL-C, apoB, LDL particle number, and Lp(a), the ongoing cardiovascular outcomes trial, and where the drug could fit alongside statins and other lipid-lowering therapies. Peter and Michael discuss the relationship between statins and diabetes risk, then turn to the potential role of obicetrapib in Alzheimer's disease prevention, exploring the genetics of APOE4 and CETP, cholesterol metabolism within the brain, and emerging biomarker data. Finally, Peter and Michael explore the benefits of omega-3 fatty acids and the challenge of delivering DHA to the brain, as well as ongoing work on klotho in preparation for clinical trials. They discuss the potential for AI to transform clinical trials and the scientific and financial challenges of developing new therapies for cardiovascular and neurodegenerative disease.

In this "Ask Me Anything" (AMA) episode, Peter takes a deep dive into the liver and its central role in metabolic health. He explains why the liver can serve as a "canary in the coal mine" for metabolic dysfunction and explores how insulin resistance, visceral fat, alcohol consumption, genetics, and hormones contribute to liver disease, along with how increasing muscle mass can benefit liver health. Peter provides a framework for understanding the progression of liver disease, highlighting which stages are reversible and why early detection matters. He explains why normal liver enzymes can provide false reassurance, which labs he uses to assess liver health, and the tools available for detecting fibrosis and more advanced disease. Peter then breaks down the interventions that can meaningfully improve liver health once risk or disease is identified, ranging from diet and exercise to GLP-1–based therapies and other medications. Finally, he examines popular claims around liver "detoxification" and supplements, separating what is supported by evidence from what is unlikely to meaningfully improve liver health.

In this episode, Peter sits down with Dr. Linus Abrams, a psychiatrist with nearly 35 years of clinical experience specializing in mood disorders and psychopharmacology, to explore how our understanding of mental health is evolving beyond the traditional neurotransmitter model. After decades in practice, Linus began questioning many of the assumptions underlying modern psychiatry, leading him to investigate how hormones, metabolism, inflammation, circadian biology, and the endocrine system shape mood and cognition. Together, Peter and Linus examine why psychiatric care should aim not only to reduce symptoms but also to restore the full human experience. They discuss how psychiatric medications work, where they fall short, and why distinguishing bipolar disorder from unipolar depression is essential for effective treatment. The conversation also explores the growing mental health burden of social isolationn associated with digital devices and social media, along with the biological factors—nutrition, exercise, sleep, and chronic stress—that influence resilience and distress tolerance. Linus explains the powerful roles of estrogen, progesterone, testosterone, and thyroid hormone in regulating mood and cognition across the lifespan. Finally, Peter and Linus review the promise and limitations of ketamine and psychedelic therapies, and why the future of psychiatry may lie in integrating neuroscience, endocrinology, and whole-body physiology to better understand, diagnose, and treat mental illness.
 
We discuss:
 
 • Linus's passion for understanding his patients and going beyond traditional psychiatry [2:45];
 • A short primer on the different classes of drugs used in psychiatry [12:45];
 • Evaluation of a patient with bipolar disorder [26:00];
 • An evolutionary perspective on depression [33:30];
 • Changes in the modern world triggering mental health problems [41:00];
 • An evolutionary perspective on insomnia [48:15];

In this episode, Peter returns to the topic of peptides, offering a clear and accessible guide to a field surrounded by both genuine scientific promise and widespread misinformation. Peptides are increasingly marketed for everything from injury recovery and muscle growth to longevity and improved appearance, often with claims that extend far beyond the available evidence. Rather than promoting or dismissing peptides as a category, Peter presents a practical framework for evaluating any peptide: what it is, how it is supposed to work, and where the science is strong, weak, or simply absent. He then applies this framework to a specific example before examining the risks of gray-market products, concerns about sourcing and quality, and where the field may be headed—ultimately helping listeners distinguish legitimate therapies from hope that has been packaged and sold without sufficient evidence.
 
We discuss:
 
 • What peptides are and why they must be evaluated individually [3:15];
 • A five-question framework for evaluating peptides and other drugs [5:30];
 • A three-tier system for classifying the scientific evidence behind peptides [10:00];
 • Evaluating BPC-157: unclear mechanisms, absent human evidence, and unknown risks [14:00];
 • Why BPC-157's expanding claims do not indicate a broad mechanism [20:45];
 • CJC-1295: biological activity versus meaningful clinical benefit [23:30];
 • Why testimonials about peptide benefits cannot establish the effectiveness of peptides [27:30];
 • The placebo effect, and the importance of controlled trials for evaluating peptides [31:00];
 • What FDA approval provides when evaluating peptide safety and effectiveness [34:45];
 • Why prescriptions from doctors, compounding pharmacies, and third-party testing do not validate unapproved peptides [38:30];
 • Approved peptides sold on the gray market: why evidence for an approved peptide does not automatically extend to gray-market versions [40:45];
 • Addressing the claim that pharmaceutical companies ignore effective natural peptides because they cannot be patented [43:00];
 • The promise of peptide science, and the risks of the gray-market wellness industry [46:30];
 • Why peptide claims must be falsifiable and why evidence should precede widespread use rather than be expected to catch up later [49:00]; and
 • More.

Jim Otvos is a biophysical chemist who pioneered the use of nuclear magnetic resonance (NMR) spectroscopy to measure lipoprotein particles and developed the first FDA-cleared method for directly quantifying LDL particle number (LDL-P), a technology that has since expanded to provide broader insights into metabolic health, inflammation, insulin resistance, and mortality risk. In this episode, Jim recounts the unlikely story of transforming a flawed cancer test into a new way of measuring lipoproteins, explains what standard cholesterol tests can miss and why LDL-P and apoB can inform treatment decisions beyond LDL cholesterol alone, and dispels the misconception that large, "fluffy" LDL particles are benign. He also explores how NMR can reveal insulin resistance before blood sugar rises, GlycA as a marker of chronic low-grade inflammation, and the metabolic vulnerability index (MVX) as a potential measure of frailty, resilience, and mortality risk across the lifespan. Finally, Jim explains why NMR diagnostics remain underused despite the wealth of information they can extract from a single blood test.
 
We discuss:
 
 • How investigating a flawed 1986 cancer test led to the development of NMR (nuclear magnetic resonance) lipoprotein testing [3:30];
 • How standard lipid panels measure cholesterol and triglycerides, and why LDL cholesterol is estimated rather than directly measured [15:15];
 • How NMR spectroscopy measures lipoprotein particle size and concentration [20:30];
 • Why LDL particle number matters more than particle size, and why large, "fluffy" LDL is not benign [28:45];
 • Discordance between LDL cholesterol and LDL particle number: which measure better reflects cardiovascular risk? [36:30];
 • How metabolic syndrome and lipid-lowering treatment contribute to the discordance between LDL-C and LDL-P, and the value of particle number for managing risk [45:30];
 • Using the NMR-derived LP-IR score to detect insulin resistance and predict type 2 diabetes before glucose rises [51:15];
 • The development, commercialization, and uncertain future of the Vantera NMR Analyzer and NMR-based diagnostics [1:04:45];
 • The analytical efficiency of NMR testing and the data-driven development of the Metabolic
 • Vulnerability Index (MVX) [1:16:00];
 • GlycA as an NMR-derived marker of systemic inflammation: its discovery, biological basis, and advantages over hs-CRP [1:25:45];
 • Developing the Metabolic Vulnerability Index (MVX): biomarkers of inflammation, malnutrition, muscle wasting, and mortality risk [1:34:00];
 • What MVX can tell us about longevity and mortality [1:44:15];
 • How MVX may reveal metabolic frailty and predict premature mortality decades in advance in young, healthy adults [1:50:30];
 • Potential applications of MVX for predicting treatment response, surgical resilience, and clinical trial outcomes, and the barriers to broader use [2:00:00];
 • ApoB versus LDL-P: their clinical similarities, the additional information provided by NMR, and barriers to broader adoption [2:07:30];
 • Interpreting the effects of the CETP inhibitor, obicetrapib, on LDL-P, apoB, and small HDL particles [2:13:00];
 • The future of NMR diagnostics and MVX: translating scientific potential into broader clinical use [2:20:45]; and
 • More.
