Skin issues like acne, eczema, and rosacea are deeply connected to internal imbalances, especially those originating in the gut. It is important to explore diet—particularly sugar, refined carbs, and dairy—because it can drive inflammation, insulin resistance, and hormonal disruption, all of which contribute to poor skin health. Topical treatments and antibiotics may provide short-term relief, but they often disrupt the skin and gut microbiome, worsening conditions over time. A Functional Medicine approach focuses on restoring gut balance, identifying food sensitivities, and supporting detoxification pathways with nutrient-dense foods, supplements, and lifestyle practices. Addressing the root causes not only improves skin but also promotes systemic healing and resilience.

In this episode, I speak with three of our doctors at The UltraWellness Center—Dr. Elizabeth Boham, Dr. Cindy Geyer, and Dr. Todd LePine—about why, when it comes to skin care, we need to look inside the body first.

Dr. Elizabeth Boham is Board Certified in Family Medicine from Albany Medical School, and she is an Institute for Functional Medicine Certified Practitioner and the Medical Director of The UltraWellness Center. Dr. Boham lectures on a variety of topics, including Women’s Health and Breast Cancer Prevention, insulin resistance, heart health, weight control and allergies. She is on the faculty for the Institute for Functional Medicine.

Dr. Cindy Geyer received her bachelor of science and her doctor of medicine degrees, with honors, from the Ohio State University. She completed residency in internal medicine at Strong Memorial Hospital in Rochester, N.Y. and is triple board certified in internal medicine, integrative medicine and lifestyle medicine.

Dr. Todd LePine graduated from Dartmouth Medical School and is Board Certified in Internal Medicine, specializing in Integrative Functional Medicine. He is an Institute for Functional Medicine Certified Practitioner. Prior to joining The UltraWellness Center, he worked as a physician at Canyon Ranch in Lenox, MA, for 10 years. Dr. LePine’s focus at The UltraWellness Center is to help his patients achieve optimal health and vitality by restoring the natural balance to both the mind and the body. His areas of interest include optimal aging, bio-detoxification, functional gastrointestinal health, systemic inflammation, autoimmune disorders, and the neurobiology of mood and cognitive disorders. Dr. LePine enjoys skiing, kayaking, hiking, camping, and golfing in the beautiful Berkshires, and is a fitness enthusiast.

Dr. Joel Warsh was trained in conventional pediatrics—but he quickly realized that vaccine conversations often overlook what matters most to you and your child’s unique health needs.

Lasting change begins with a shift in both mindset and behavior. Many people remain stuck in self-defeating patterns because of unconscious narratives, emotional triggers, and a disconnection from their body’s inner wisdom. Change isn’t just about willpower or information—it’s about learning to rewire the brain through small, intentional actions that generate powerful emotional feedback loops. Identity transformation happens not through repetition, but through experiences that create a sense of success. In a world flooded with conflicting advice and manipulative marketing, reclaiming agency requires tuning into your own signals, building self-trust, and recognizing that behavior change is a design challenge—not a character flaw. Empowerment comes from realizing that the ability to change is built into who we are as humans.

In this episode, I speak with Tom Bilyeu, Dr. Rangan Chatterjee, and Dr. BJ Fogg about cracking the nut of behavior change.

Tom Bilyeu is a filmmaker and serial entrepreneur best known as the co-founder of Quest Nutrition, a billion-dollar company built to combat metabolic disease through value-driven innovation. After nearly a decade of chasing financial success and feeling unfulfilled, he realized the importance of loving the struggle itself. This insight led him and his partners to shift focus from profit to purpose. Quest quickly became the second fastest-growing company in North America, according to Inc. Magazine. After achieving significant personal wealth, Tom turned to the other global crisis he saw—disempowering mindsets. To address this, he co-founded Impact Theory, a media studio with his wife, Lisa Bilyeu. Their mission is to scale mindset transformation by producing empowering content that shifts the cultural subconscious. Just as Disney built the most magical place on Earth, the Bilyeus aim to build the most empowering one.

Dr. Rangan Chatterjee is regarded as one of the most influential doctors in the UK. A practicing GP for the last two decades, Dr. Chatterjee wants to inspire people to transform their health by making small, sustainable changes to their lifestyles. Host of the #1 Apple podcast, Feel Better, Live More, and presenter of BBC 1’s Doctor in the House, Dr. Chatterjee is the author of 5 Sunday Times bestselling books and his TED Talk, “How to Make Diseases Disappear,” has now been viewed over 4.8 million times. His newest book is Happy Mind, Happy Life: The New Science of Mental Well-Being.

Dr. BJ Fogg is a behavior scientist, author, and founder of the Behavior Design Lab at Stanford University, where he has researched human behavior since 1998. He developed the groundbreaking “Behavior Design” system, which explains how behavior works and how to design it effectively. Over the past decade, his lab has focused on practical applications—from helping people navigate coronavirus-related challenges to training climate change professionals in behavior change strategies. BJ is also the creator of the “Tiny Habits” method, a simple, science-backed approach to habit formation that has helped over 40,000 people make lasting life changes. His work empowers individuals and organizations to design behavior that benefits both people and the planet. He shares his insights in the New York Times best-selling book, Tiny Habits: The Small Changes That Change Everything.

Up to 80% of people may be living with insufficient levels of vitamin D, magnesium, and omega-3 fatty acids—three essential nutrients involved in critical functions like immune defense, cardiovascular health, mood regulation, and brain function. Modern lifestyles—marked by nutrient-poor diets, low sun exposure, chronic stress, and overuse of medications—disrupt the body’s ability to absorb and maintain these key nutrients. Deficiencies often go undiagnosed due to outdated testing, yet they’re strongly linked to conditions like depression, fatigue, diabetes, and heart disease.

In this episode, I talk about, along with Andrew Huberman, how modern lifestyles and diets lead to widespread nutrient deficiencies and chronic disease—and how targeted nutrition and lifestyle changes can restore optimal health.

Dr. Andrew Huberman is a neuroscientist and tenured Professor in the Department of Neurobiology at the Stanford University School of Medicine. He has made numerous important contributions to the fields of brain development, brain function, and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviors, skills, and cognitive functioning. Dr. Huberman is a McKnight Foundation and Pew Foundation Fellow and was awarded the Cogan Award in 2017, which is given to the scientist making the largest discoveries in the study of vision. His lab’s most recent work focuses on the influence of vision and respiration on human performance and brain states such as fear and courage. Work from the Huberman Laboratory at Stanford University School of Medicine has been published in top journals including Nature, Science, and Cell and has been featured in TIME, BBC, Scientific American, Discover, and other top media outlets.

Who in the world would try to lower their cholesterol by eating an entire sleeve of Oreos every day for a month? Meet Nick Norwitz, PhD, an Oxford graduate and Harvard medical student who did just that—in an effort to test a hypothesis about cholesterol and metabolic health.

There has been a fundamental shift in understanding metabolic health and chronic disease, particularly Type 2 diabetes, challenging long-standing dietary dogma by emphasizing that insulin resistance is largely driven by overconsumption of refined carbohydrates, not dietary fat or red meat. While highlighting the success of carbohydrate restriction and ketogenic approaches, nutrition is being seen as a powerful tool for reversing diabetes—often more effective and sustainable than conventional medication. The implications are far-reaching, not only for individual health outcomes, but also for reshaping public health strategies in addressing today’s chronic disease epidemic.

In this episode, I speak with Gary Taubes, Sami Inkinen, and Dr. Greeshma Shetty about an approach to treating Type 2 Diabetes that works. I also discuss how red meat is not to blame, but we should be looking at high sugar and starch diets.

Gary Taubes is an award-winning science and health journalist, and co-founder and director of the Nutrition Science Initiative (NuSI). He is the author of The Case Against Sugar, Why We Get Fat, Good Calories, Bad Calories, and, most recently, The Case for Keto. Gary is a former staff writer for Discover and correspondent for Science. He has written three cover articles on nutrition and health for The New York Times Magazine, and his writing has also appeared in The Atlantic, Esquire, and numerous "best of" anthologies, including The Best of the Best American Science Writing (2010). He has received three Science in Society Journalism Awards from the National Association of Science Writers, and is also the recipient of a Robert Wood Johnson Foundation Investigator Award in Health Policy Research. He lives in Oakland, CA.

Sami Inkinen is the CEO and Co-Founder of Virta Health, a pioneer in reversing diseases like obesity and type 2 diabetes through a nutrition-first approach. Sami's personal connection to diabetes and passion to advance global health was the motivation behind Virta and its innovative care model. Previously, Inkinen was the co-founder of the leading online real estate marketplace Trulia, serving as its COO and president and board member until its IPO and eventual sale to Zillow Group.

Dr. Greeshma Shetty, board certified in Internal Medicine and Endocrinology, currently serves as a Lead Clinician in the Virta Medical Group and the Director of Quality and Safety at Virta Health. Prior to joining Virta, she was clinical physician educator at Harvard Medical School, where she directed the combined Joslin - Beth Israel Deaconess Endocrine Fellowship program and Co-Directed the Asian American Diabetes Initiative.

Many people struggle with mysterious symptoms like fatigue, brain fog, food sensitivities, and skin issues—only to be misdiagnosed or dismissed altogether. This conversation highlights how histamine intolerance and mast cell activation syndrome can be the hidden drivers behind a wide range of chronic conditions, and why they're often overlooked in conventional medicine. From the role of gut health, food triggers, and environmental toxins to deeper root causes like Lyme disease or mold exposure, it’s clear that personalized, Functional Medicine is key to uncovering real answers. Understanding the immune system’s role in histamine reactions—and how even “healthy” foods can be inflammatory for some—is a critical step toward healing.

In this episode, I talk with Dr. Todd LePine, Dr. Elizabeth Boham, and Dr. Mark Pimentel about what histamine intolerance is, how it can be related to gut health, and why it’s important to address it.

Dr. Todd LePine graduated from Dartmouth Medical School and is Board Certified in Internal Medicine, specializing in Integrative Functional Medicine. He is an Institute for Functional Medicine Certified Practitioner. Prior to joining The UltraWellness Center, he worked as a physician at Canyon Ranch in Lenox, MA, for 10 years.
