For over fifty years, Americans have been told that cutting fat was the key to better health. Yet after decades of low-fat guidelines, rates of obesity, diabetes, and metabolic dysfunction have skyrocketed - now affecting more than 88% of the population.

In this episode of The Metabolic Link, Victoria Field sits down with Dr. Nina Teicholz, science journalist and author of The Big Fat Surprise, whose decade-long investigation into nutrition science uncovered how flawed evidence and policy decisions shaped the way we eat. Her peer-reviewed research reveals a troubling gap between the science and the guidelines meant to protect public health.

Answered in this episode:

• How did you transition from investigative journalism into becoming one of the leading voices challenging nutrition policy?
• What specifically makes the original science behind the low-fat diet hypothesis so weak?
• How did Ancel Keys' controversial research become official U.S. nutrition policy?
• What were the metabolic consequences when Americans replaced dietary fat with carbohydrates?
• How did seed oils come to dominate the American food supply, and what are the metabolic implications?
• What do randomized controlled trials reveal about low-carb versus low-fat diets for metabolic health?
• How has industry funding influenced the direction of nutrition research and policy?

This conversation provides a rigorous examination of how weak associational data became entrenched policy, the metabolic consequences of replacing saturated fats with refined carbohydrates and seed oils, and what the path forward looks like for evidence-based nutrition science.

When veterinarian Dr. Loren Nations lost his wife to aggressive cancer despite the best conventional treatments, he didn't just grieve—he revolutionized his entire approach to medicine. In this deeply personal conversation, Dr. Nations reveals how tragedy led him to discover that our pets are experiencing metabolic disease at rates even higher than humans, with 61% of cats and 59% of dogs now obese.

Dr. Loren Nations is a board-certified veterinarian with over 30 years of experience. He's the founder of Veterinary Healthcare Associates, Ascend Vets, and Neoterric, pioneering the integration of ketogenic nutrition, hyperbaric oxygen therapy, and metabolic medicine into veterinary care.

Questions Answered in This Episode:

• What metabolic-based therapies are you using alongside standard care, and which have proven most effective?
• Can dogs and cats safely eat ketogenic diets without developing pancreatitis?
• How do you approach gut healing in pets, and what specific strategies or supplements do you use beyond nutrition?
• What happens when you treat pet cancer with metabolic therapies instead of just conventional oncology?
• What can veterinary medicine teach us about human metabolic health?

This conversation bridges two worlds we rarely see connected—showing how the metabolic principles transforming human health apply equally to our animal companions, and how healing our pets might just teach us to heal ourselves.

What if the food you eat could change the way you breathe at night? In this episode, recorded live at The Metabolic Health Summit, Dr. Jonathan Jun reveals how metabolism and sleep-disordered breathing are deeply connected, and why shifting from carbs to fat might improve more than just your waistline.

Dr. Jonathan Jun, a leading researcher on obesity hypoventilation syndrome (OHS) and obstructive sleep apnea (OSA), walks us through the groundbreaking KETOHS trial, where a ketogenic diet was tested for its effects on carbon dioxide retention, sleep apnea severity, and metabolic health. The findings suggest ketosis may do more than promote weight loss - it could directly enhance respiratory efficiency and sleep quality in patients with OHS and OSA.

From a long-forgotten 1976 fasting study to modern clinical data, this lecture reframes the connection between diet, breathing, and metabolism, revealing how nutritional ketosis might transform respiratory and metabolic medicine.

Questions Answered in This Episode:

• Why does fuel choice (carbs vs. fat) matter for breathing in people with sleep-disordered breathing?
• What exactly happens in obesity hypoventilation syndrome (OHS), and why is it more dangerous than OSA alone?
• Why did a 1976 starvation ketosis study inspire modern trials on ketogenic diets for OSA/OHS?
• How was the KETOHS trial designed to isolate the effects of ketosis itself (not just weight loss)?
• Can a ketogenic diet improve sleep apnea severity even without CPAP therapy?
• Is the improvement in CO₂ clearance explained only by weight loss, or something else?
• What metabolic changes accompany ketogenic therapy in this context?

This episode will change the way you see the link between diet and breathing, and may open new doors for treating some of the toughest sleep and metabolic disorders.

Could treating food like a drug be the breakthrough we've needed in food addiction treatment?

In this episode of The Metabolic Link, Dr. Dominic D’Agostino sits down with Dr. Tro Kalayjian - physician, researcher, and former obesity patient - to explore whether food addiction should be classified as a true addiction, and how his TOWARD model is helping patients overcome binge eating and food-related compulsions.

Dr. Tro shares findings from his recent peer-reviewed paper, TOWARD: a Metabolic Health Intervention That Improves Food Addiction and Binge Eating Symptoms. The study evaluated outcomes from the TOWARD intervention, a telemedicine-based model that combines metabolic nutrition, real-time biofeedback, and coaching. Nearly half of participants reduced food addiction symptoms, and over 80% saw improvements in binge eating - often independent of weight loss.

This conversation explores the science of dopamine signaling, the failure of calorie-restriction models, the blurred line between food addiction and eating disorders, and how this approach could reshape treatment through scalable, real-world solutions.

Questions Answered in This Episode:

• How should we define food addiction compared to binge eating disorder?
• Should ultra-processed food addiction be officially recognized in the DSM?
• Why is food addiction harder to treat than drug or alcohol addiction?
• What were the key outcomes of the TOWARD study on food addiction and binge eating?
• Can lifestyle interventions compete with bariatric surgery or GLP-1 drugs?
• How can employers scale food addiction treatment for high-risk populations?

Muscle isn’t just about strength or performance — it’s metabolic armor. In this episode of The Metabolic Link, Dr. Andy Galpin sits down with hosts Victoria Field and Dr. Dominic D’Agostino to show how muscle, cardio fitness, and bone density work together to protect against decline and extend healthspan. From women’s training and recovery practices to kids in the weight room, Dr. Galpin translates decades of research into practical strategies anyone can use.

Big questions Dr. Galpin helps answer:

• How does muscle mass protect against metabolic decline and early mortality?
• What’s the safest, most effective on-ramp to rebuild bone density and explosiveness after 40?
• When is fasted training useful for women, and when is it counterproductive?
• How early can kids start resistance training — and what should it look like?
• Which recovery practices are underrated (free) versus overrated (pricey)?

Dr. Andy Galpin is a tenured full professor and human performance scientist with a PhD in Human Bioenergetics and an MS in Human Movement Sciences. He previously ran the Center for Sport Performance and the Biochemistry & Molecular Exercise Physiology Lab at Cal State Fullerton, and now serves as Executive Director of the Human Performance Center at Parker University.

Plastic surgery meets metabolic medicine.

Dr. Cameron Chesnut isn't just changing faces - he's changing the entire surgical process. In this episode, Dr. Dominic D'Agostino talks with the facial plastic surgeon who’s using ketones, hyperbaric oxygen, red light, and regenerative protocols to optimize brain health, accelerate recovery, and eliminate opioids entirely.

Trusted by high performers around the world, Dr. Chesnut is known for delivering natural, rejuvenated, and seemingly untouched results through minimally invasive procedures. His practice integrates regenerative medicine, metabolic science, and next-level recovery techniques — all grounded in a personal performance protocol as refined as his surgical outcomes.

In this episode, he and Dr. Dominic D’Agostino unpack the future of surgical care: ketones for cognitive protection, hyperbaric oxygen for faster healing, red light and PEMF for recovery, and the anesthesia protocols he uses to avoid post-op brain fog — and eliminate opioids altogether.

This isn’t cosmetic — it’s clinical strategy. And it could change the face of plastic surgery as we know it.

Did you know that over 7 million Americans live with Alzheimer’s—and that number is expected to nearly double by 2050? Despite decades of research and billions spent, most treatments only offer minimal slowing of symptoms.

But what if we’ve been approaching this disease all wrong?

In this powerful episode of The Metabolic Link, host Victoria Field sits down with renowned neurologist, researcher, and bestselling author Dr. Dale Bredesen. He shares how Alzheimer’s isn’t caused by one thing—and why he says a single-pill solution is a fundamentally flawed approach. Dr. Bredesen discusses his 30+ years of research into cognitive decline, the systems-based ReCODE Protocol that’s showing incredible success in reversing symptoms, and why early detection is everything.

From brain biomarkers to root causes like inflammation, toxins, and metabolic dysfunction, this is a masterclass on how we can take action—long before symptoms take hold.

Can metabolic therapy play a transformative role in the treatment of serious mental illness?

In this episode of The Metabolic Link, host Victoria Field speaks with Dr. Erin Bellamy - a Chartered Psychologist, Metabolic Psychiatry Practitioner, and CEO of IKRT - about the clinical application of ketogenic metabolic therapy (KMT) for psychiatric disorders. With over a decade of experience and a PhD focused on ketogenic diets for depression, Dr. Bellamy offers deep insight into the mechanisms driving psychiatric disease - including brain hypometabolism, mitochondrial dysfunction, neuroinflammation, and insulin resistance - and how KMT targets these shared biological pathways.

This conversation explores real-world implementation of ketogenic therapy in patients with diagnoses such as PTSD, ADHD, binge eating disorder, and schizoaffective disorder. Dr. Bellamy also shares her recently published case study demonstrating transdiagnostic remission using KMT, along with the clinical protocols, macronutrient ratios, and outcomes she’s seeing in her group and one-on-one programs.

Whether you’re a psychiatrist, psychologist, or healthcare professional interested in emerging metabolic therapies for mental health, this episode offers valuable clinical and translational insights into a rapidly evolving field.
