This week in the studio, I'm joined by Dr. Nick Barringer—Army Ranger, performance nutrition expert, and one of the sharpest minds in military and metabolic health. Together, we cut through the noise around today's most controversial nutrition topics. If you’ve ever felt whiplash trying to make sense of conflicting headlines, this episode is your science-based compass.

What’s really going on with artificial sweeteners like sucralose and aspartame? Are seed oils toxic—or just misunderstood? And what’s the actual science behind popular supplements like creatine, testosterone boosters and fat burners?

Dr. Barringer brings two decades of elite military and research experience to help us separate hype from evidence—while sharing real-world tools that help people perform, think, and feel better.

We cover:

• Whether sucralose and other artificial sweeteners damage DNA or gut health
• What to actually worry about with food dyes
• Seed oils, inflammation, and what most people get wrong about them
• Protein and carb dosing for people over 40 (and how to think about fiber and fat)
• Why creatine is still the most underrated supplement for muscle and brain function
• Tactical hydration tips (and how sweat composition varies with diet)
• Hidden risks in testosterone boosters and “fat burners”
• Practical takeaways for elite performance, healthy aging, and being stronger at any age

Who is Dr. Nick Barringer?

Nick Barringer, PhD, is a Nutritional Physiologist with deep experience in both applied and academic settings. He directed the U.S. Military-Baylor Graduate Program in Nutrition, taught at West Point, and was the first active-duty dietitian to graduate U.S. Army Ranger School and serve with the 75th Ranger Regiment. He holds a PhD in kinesiology from Texas A&M, and his research on tactical nutrition has been featured in outlets like Science Daily and Men’s Journal.

In this episode, I’m joined by Shaun Noorian—engineer, entrepreneur, and CEO of Empower Pharmacy, the largest compounding pharmacy in the world. With compounded GLP-1s making headlines and lawsuits from Big Pharma intensifying, Shaun joins me to pull back the curtain on the regulatory, financial, and ethical storm brewing behind the scenes.

Are compounded GLP-1s legal? Safe? Who controls drug pricing in the U.S., and why are Americans paying 10x more than Europeans for the same medication? And most importantly—what does all this mean for access, affordability, and patient care?

This episode is a wake-up call. If you care about transparency in medicine, patient rights, or access to life-saving medications, don’t miss this one.

We cover:

• Why compounded GLP-1s are under attack—and what the FDA’s recent moves really means
• How Big Pharma sets drug prices—and why Americans pay up to 10x more than other countries
• The legal battle over semaglutide, regulatory capture, and the influence of pharmaceutical lobbying
• How compounding pharmacies offer personalized care and expand access to life-saving medications
• What’s next for patients, clinicians, and the future of affordable medicine in the U.S.

Who is Shaun Noorian?

In this episode, I’m joined by Dr. Melanie Cree—physician-scientist, pediatric endocrinologist, and one of the leading researchers redefining how we understand and treat Polycystic Ovary Syndrome (PCOS). PCOS affects millions of women, yet it's still underdiagnosed, misunderstood, and often mistreated. Dr. Cree cuts through the confusion, offering a deeply scientific yet compassionate look at what’s really driving this complex condition—from insulin resistance and mitochondrial dysfunction to skeletal muscle quality and fertility trajectories across a woman’s lifespan.

We cover:

• Why PCOS isn’t a single disease—and what two phenotypes may explain the full picture
• How muscle, liver, and fat interact in PCOS
• The misunderstood role of testosterone, insulin, and SHBG in diagnosis
• What muscle biopsies reveal about teenage girls with PCOS
• Intramuscular fat, mitochondrial impairment, and the true cost of sedentary muscle
• How early lifestyle and exercise interventions could change the future of PCOS care
• What GLP-1 agonists and amino acid supplements might offer for treatment

Whether you’re a clinician, patient, or advocate for women’s health, this episode will give you a whole new lens on PCOS—and why skeletal muscle may be the most overlooked (and powerful) organ in the conversation.

Who is Dr. Melanie Cree?

Dr. Melanie Cree is a board-certified pediatric endocrinologist and Associate Professor at the University of Colorado and Children’s Hospital Colorado, where she directs a leading multidisciplinary PCOS clinic. Her research bridges metabolic medicine and muscle physiology, with clinical trials exploring semaglutide, amino acid therapy, liver metabolism, and insulin resistance in adolescents.

Jeff Krasno’s personal health transformation—reversing diabetes, shedding 60 pounds, and reclaiming his health at age 50—is a masterclass in what he calls “good stress.” In this episode, we dive into the simple but powerful idea that discomfort might just be the medicine we all need. Jeff, the founder of Commune and host of the Commune podcast, shares how fasting, cold exposure, resistance training, and attention to modern habits helped him regain his energy, build muscle, and thrive.

Together, we discuss how metabolic dysfunction has become the norm, how adaptive stress responses can be harnessed to reverse chronic illness, and why building muscle is not only the antidote to obesity but also a critical factor in longevity. If you’re interested in reclaiming your vitality and learning how to work with—not against—your biology, this episode will speak to you.

We cover:

• Jeff’s story of personal health transformation at midlife
• What “good stress” is and how to harness it to improve health
• Why chronic ease leads to chronic disease
• Cold therapy, fasting, and training as adaptive stressors
• The importance of resistance training for blood sugar control
• How metabolic dysfunction hides in plain sight
• Practical tips to increase non-exercise activity thermogenesis (NEAT)
• Building muscle as the path to longevity and disease prevention

Nelson Vergel’s story is one of resilience, perseverance, and an unrelenting drive to defy the odds. In the mid-1980s, he was handed what many would have considered a death sentence—an HIV diagnosis at a time when there were no effective treatments, no clear answers, and little hope. Today, he is a beacon of knowledge and empowerment for those seeking to take control of their health, whether they are dealing with wasting conditions, hormone deficiencies, or simply aiming for peak performance. Nelson has spent decades researching and advocating for hormone health, muscle preservation, and medical autonomy, particularly for those facing wasting conditions like HIV and cancer. His work has helped shape the conversation around androgen therapies, the role of anabolic agents in aging, and the intersection of GLP-1 medications with muscle loss.

We cover:

Dr. James Hill—a expert on obesity, metabolism, and long-term weight management—joins me this week to unpack the biggest challenges in sustainable fat loss. Dr. Hill has spent decades researching weight control and the factors that determine whether people can keep weight off long-term. We discuss the science behind energy balance, metabolic flexibility, and why long-term weight loss is about more than just diet and exercise. He shares insights from his groundbreaking work with the National Weight Control Registry, the role of GLP-1 medications, and why physical activity is the key to preventing weight regain.

We cover:

• The critical differences between weight loss and weight maintenance
• Why physical activity is perhaps more important for keeping weight off than losing it
• The National Weight Control Registry: lessons from long-term weight loss success stories
• How metabolism, muscle mass, and energy expenditure affect weight regain
• The role of protein and resistance training in preserving lean mass
• The impact of GLP-1 medications on weight loss and why most people regain weight after stopping them
• The psychology of weight maintenance: mindset, self-monitoring, and behavior change

If you’ve ever struggled to keep weight off, or you’re interested in the latest research on metabolic health and sustainable weight management, this episode is a must-listen.

Misinformation in nutrition is rampant. From demonizing red meat to hyping plant-based diets, conflicting advice has left many people confused about what’s truly evidence-based. In this episode, I am joined by Dr. Bradley Johnston, an expert in evidence-based nutrition and public health policies, to separate fact from fiction. With nearly 200 peer-reviewed publications, Dr. Johnston has challenged conventional wisdom—including recommendations from major organizations like the World Health Organization. He shares how evidence-based practices should guide our dietary choices, the importance of systematic reviews and meta-analyses, and how cognitive biases influence the research we trust.

Key Points:

• How evidence-based guidelines are formed—and why they sometimes change
• The three pillars of evidence-based practice and why patient values matter
• Why most nutrition studies aren’t as strong as we think—and how to critically evaluate them
• What the best available research actually says about dietary patterns for longevity
• The role of AI in research and whether it’s a help or hindrance to scientific rigor

If you’ve ever questioned dietary guidelines, nutrition headlines, or conflicting health advice, this episode is a must-listen. Get ready to rethink everything you thought you knew about nutrition.

Who is Dr. Bradley Johnston?

Dr. Bradley Johnston is an Associate Professor at Texas A&M University, specializing in evidence-based nutrition, and the methodology of patient-reported outcomes, randomized clinical trials, systematic reviews, and clinical and public health practice guidelines.

With a PhD in experimental medicine from the University of Alberta and post-doctoral training in evidence-based practice, epidemiology and biostatistics from Oxford and McMaster University, his research focuses on advancing human health research methodology to improve clinical and dietary practice recommendations and public health policies. He co-leads EvidenceBasedNutrition.org and NutriRECS, develops nutrition education resources (e.g. Nutrition Users’ Guides), and currently serves as Co-Chair of the Canadian Pediatric Obesity Management Guidelines, ensuring clinical and public health guidelines are backed and transparently supported by the best available evidence, including end user values and preferences, absolute estimates of effect and the certainty of evidence for estimates of effect. His overall aim is to empower patients, clients and members of the public to make fully-informed health care decisions based on the central tenets of evidence-based practice and policy.
