Inflammation and Glycation: The Two Heads of Chronic Disease | Dr. Paul Reynolds, PhD | The Metabolic Link Ep. 96
Dr. Paul Reynolds has spent his career studying what he calls “two heads of the same beast”: inflammation and glycation — two interlocking processes that may help explain why so many chronic diseases are connected, even when they are treated as separate conditions. Dr. Reynolds is a professor and research scientist at Brigham Young University whose NIH-funded research program studies inflammation, lung biology, glycation, and the AGE/RAGE receptor system that links metabolic and environmental...

Metabolic Psychiatry in Clinical Practice: Brain Energy, Common Pitfalls, & Precision Nutrition | Dr. Bret Scher, MD | The Metabolic Link Ep. 95
In people with severe depression and cognitive decline, brain glucose metabolism has been shown in some studies to decline measurably. Ketone metabolism, by contrast, appears relatively preserved. That single observation is reshaping how researchers think about psychiatric illness. In this episode, Dominic D'Agostino sits down with Bret Scher, a cardiologist who pivoted to metabolic psychiatry and now leads clinical education and content for Metabolic Mind at the Baszucki Group. Dr. Scher bri...

Inuit Metabolism Revisited: Ketosis, Omega-3s, & the CPT1A Arctic Variant | Dr. Gideon Mailer & Nicola Hale | The Metabolic Link Ep. 94
A gene mutation that reduces ketone production in the fasted state is associated with sudden infant death in modern populations. But in the ancestral context where it evolved alongside an omega-3-rich diet, it may have been part of what kept infants alive. Dr. Gideon Mailer and Nicola Hale join The Metabolic Link to present their hypothesis that the CPT1A L479 Arctic variant is not anti-ketogenic but pro-metabolic flexibility, conserving glucose by upregulating ketosis at the fed-state thresh...

Understanding Female Metabolism: PCOS, Postpartum, and Menopause | Madison Kackley, PhD | The Metabolic Link
In a 12-week clinical trial at The Ohio State University, every woman with PCOS who completed the intervention experienced a change in her menstrual status. One participant, who had never had a period in her life, began menstruating within a week. Another saw spotting after five years of amenorrhea while taking only a ketone supplement without adopting a ketogenic diet. These are among the earliest controlled findings linking ketogenic interventions directly to reproductive hormone restoratio...

Vagal Nerve Stimulation, TBI, and Brain Health: Rethinking Neurological Care | Dr. Michael Hoffman, MD | The Metabolic Link Ep. 92
A veteran walks into the clinic with a persistent migraine. Four minutes of vagal nerve stimulation later, the migraine is gone. This is not a one-off result. It is what Dr. Michael Hoffman has been observing for over seven years in the VA hospital system, using non-invasive devices he considers severely underutilized. Dr. Hoffman is a stroke and cognitive-behavioral neurologist who trained at Columbia University, spent 14 years in the VA system, and has evaluated an estimated 10,000 stroke patients across his career. He now practices at the University of Central Florida, where he integrates ketogenic nutrition, advanced imaging, vagal nerve stimulation, and hyperbaric oxygen into his neurological care. In this episode, Dr. Hoffman walks through what he calls the "five brain fitness rules," the specific, measurable lifestyle prescriptions he gives every patient, and explains why standard cognitive screening tools like the MoCA and Mini Mental miss the most dramatic behavioral syndromes caused by brain injury. He also discusses why PET scans and diffusion tensor imaging should be used far more often, and why post-TBI hormonal evaluation is critical but routinely overlooked. Questions Answered in This Episode: What are the five brain fitness rules every neurological patient should follow? Why do standard cognitive tests fail to detect some of the most severe brain injury syndromes? How is vagal nerve stimulation treating migraines, and why is it so underutilized outside the VA? What clinical changes would most improve neurological care today? Does the evidence support hyperbaric oxygen therapy for traumatic brain injury? Could fungal infections contribute to some long-standing Alzheimer's diagnoses? What is the surprising decade when your brain's cognitive function peaks? Dr. Hoffman makes a case that the gap between what we know about the brain and what we do in clinical practice has never been wider, and that closing it starts with giving clinicians the time and tools to actually examine their patients.

What's in Your Tap Water? Contaminants, Filtration, and How to Test It | Johnny Pujol | The Metabolic Link Ep. 91
You could have elevated levels of contaminants like uranium or arsenic in your drinking water—and not know it. Many of these compounds are colorless, odorless, and undetectable without testing. Johnny Pujol is a water chemist and the founder of Tap Score, a drinking water testing platform supported by a network of roughly 270 specialized laboratories. His path from electrochemistry research to consumer water testing was driven by a simple realization: the chemistry inside what looks like a clear glass of water is far more complex than most people realize. In this episode, Dr. Dominic D’Agostino and Johnny break down what’s actually in drinking water, how regulatory standards are set, and where they may lag behind emerging research. They also discuss how chronic exposure to certain contaminants may intersect with metabolic health and long-term disease risk. Johnny also shares insights from Tap Score’s forthcoming research comparing contaminant profiles in unfiltered tap water, bottled water, and filtered tap water. Questions Answered in This Episode: Why does the EPA action level for lead differ from the ideal target of zero? Can certain filtration systems introduce unintended issues, like microbial growth, if not properly maintained? How can environmental factors like rainfall impact private well water quality? What's the difference between a "first draw" sample and a "representative" sample, and why does it matter? Is the health risk from showering in contaminated water meaningful compared to drinking it? Why do some water tests cost $600 to $800 while others cost a fraction of that? Understanding your drinking water starts with recognizing the difference between what’s legally permitted and what may be considered optimal from a health perspective. This conversation explores that gap, and what individuals can do to better assess their own water quality.

Rethinking Cognitive Decline: Stimulus, Exercise, and the Aging Brain | Dr. Tommy Wood, MD, PhD | The Metabolic Link Ep. 90
Register for a live Q&A with Dr. Tommy Wood on Wednesday, March 25th. Decreased glucose uptake in the brain is often considered a hallmark of Alzheimer's disease. But Dr. Tommy Wood asks whether part of that metabolic signature may reflect how little cognitive demand we place on the brain. He sits down with Dr. Dominic D'Agostino for a nuanced conversation on metabolic health and cognitive function.. Dr. Wood is a neuroscientist, neonatal brain injury researcher, and author of The Stimulated Mind. This episode follows the metabolic thread through every stage of brain health. Pre-diabetes and type 2 diabetes as predictors of cognitive decline. Neurovascular coupling as the reason heart disease risk factors double as brain disease risk factors. Lactate crossing the blood-brain barrier to drive BDNF production where it actually matters. Creatine as a brain energy distributor that most people still only associate with muscle. Dr. Wood lays out his Three S Model — Stimulus, Supply, Support — and makes the case that cognitive demand drives glucose uptake into the brain the same way muscular contraction drives it into skeletal muscle. Questions Answered in This Episode: Does the brain respond to energy demand the same way skeletal muscle does? What role does creatine play in brain energy distribution, and what do the clinical trials show? Can heavy resistance training produce the same brain-relevant lactate response as HIIT? How should exercise be dosed after a concussion or traumatic brain injury? Is cognitive decline in your 50s, 60s, and 70s actually inevitable, or is that a statistical artifact? Why are pre-diabetes and metabolic syndrome among the strongest predictors of dementia? The mechanistic throughline here is demand-driven metabolism. Dr. Wood makes the case that the same principles governing glucose uptake in skeletal muscle apply to the brain — and the conversation gets into what that means for how we interpret FDG-PET data, design lifestyle interventions, and think about neurodegeneration itself.

Journal Club: Five Papers Pushing the Boundaries of Metabolic Therapy | The Metabolic Link Ep. 89
Get free access to our new Ketogenic Metabolic Therapy ebook here. Could changing your metabolism reduce alcohol cravings, ease psychiatric symptoms, and even make cancer immunotherapy more effective? The science is pointing to yes, and the mechanisms are fascinating. In this Journal Club episode, co-hosts Victoria Field, Dr. Dominic D'Agostino, and Dr. Angela Poff break down five peer-reviewed papers from their newly released Ketogenic Metabolic Therapy ebook (Volume 4). From a French preclinical study showing ketogenic diet enhances PD-L1 immunotherapy response in kidney cancer, to an NIH/UPenn trial using machine-learning-derived fMRI signatures to measure reduced alcohol cravings during ketosis, to Stanford's pilot trial demonstrating notable metabolic and psychiatric improvements in schizophrenia and bipolar disorder, this episode covers the cutting edge of metabolic therapy research. Questions Answered in This Episode: Why does the brain crave alcohol in people with alcohol use disorder, and how might ketones help? How might a ketogenic diet affect a tumor’s response to immunotherapy? Can insulin resistance in the brain contribute to psychiatric symptom severity? How does the ketogenic diet compare to the Mediterranean diet for autoimmune inflammation? Does timing of ketogenic diet initiation matter for chronic pain relief? Is it realistic for people with serious mental illness to adhere to a ketogenic diet? Whether you're a clinician, researcher, or someone looking to understand the latest science, this episode reveals just how far-reaching ketogenic metabolic therapy has become, spanning oncology, psychiatry, addiction, autoimmune disease, chronic pain, and much more!
