    The Inflammation Code w/ Dr. Shivani Gupta

    In this episode, Detective Ev sat down with Dr. Shivani Gupta, a leading voice in holistic health and chronic disease prevention, whose work bridges 5,000 years of Ayurvedic wisdom with modern functional medicine. Dr. Shivani’s journey into wellness began with her own battle with chronic illness—an experience that led her to Ayurveda and ultimately transformed her life. Inspired to help others heal, she went on to earn a Master’s in Ayurvedic Sciences and a Ph.D. focused on Turmeric, studying under renowned Ayurvedic experts in both India and the United States. At the heart of her work is The Inflammation Solution Program, a practical, integrative approach designed to help people—especially women—address chronic issues such as joint pain, weight gain, autoimmune symptoms, fatigue, and hormone imbalance. By blending traditional Ayurvedic principles with evidence-based functional medicine, Dr. Shivani empowers individuals to understand their bodies and restore balance from the inside out. We also dive into her new Hay House debut book, The Inflammation Code, where she reveals how hidden inflammation drives brain fog, metabolic dysfunction, accelerated aging, and more.     Want to watch this episode on YouTube? Click here. Subscribe if you'd like to catch all new episodes live and participate with our guests directly.   Want to learn more about becoming an FDN? Go to fdntraining.com/resources to get our best free workshops and mini-courses!

    Mold Illness is Why My Health Fell Apart w/ Katie Poterala

    What happens when your body begins to fail—and no one can tell you why? In this powerful episode of The Health Detective Podcast, Katie shares her deeply personal health journey through sudden illness, mold exposure, and the long road back to healing. What started as an unexplainable health collapse quickly became a life-altering wake-up call—one that forced her to become her own #1 advocate. At the time, Katie was juggling a brand-new baby and running a busy retail jewelry store she had just opened in downtown Greenville, South Carolina. Despite the obvious stressors, the severity and speed of her illness didn’t make sense. Traditional medicine offered endless testing, referrals, medications, and even repeat surgeries—but no real answers, no roadmap, and no explanation for why her body was responding the way it was. Refusing to accept a life of unanswered questions, Katie dove headfirst into functional medicine, investing countless hours, resources, and education to uncover the root cause of her symptoms. Along the way, she discovered that there is always a reason the body responds the way it does—and that healing is possible when you find the right method and the right help.     Want to watch this episode on YouTube? Click here. Subscribe if you'd like to catch all new episodes live and participate with our guests directly.   Want to learn more about becoming an FDN? Go to fdntraining.com/resources to get our best free workshops and mini-courses!

    The Truth About Melasma: A Metabolic Condition in Disguise w/ Ariana Juarez

    Is melasma really a skin problem—or is it your body asking for help? In this episode of The Health Detective Podcast, Detective Ev sat down with Ariana Juarez, Functional Diagnostic Nutrition Practitioner (FDN-P) and founder of Alura Wellness, to uncover the truth behind chronic hyperpigmentation and melasma. If you’ve tried creams, lasers, peels, or prescriptions—only to see dark patches return—this conversation explains why those approaches so often fail. Ariana breaks down melasma as a metabolic skin condition, not a cosmetic flaw. Rather than being something to “cover up” or burn away, melasma is a visible signal of deeper internal imbalance involving hormones, blood sugar regulation, inflammation, detox pathways, and nutrient status. When those drivers aren’t addressed, surface-level treatments can’t create lasting change. The good news? Melasma is reversible when you understand what your skin is communicating and address the root cause.  Ariana shares how her functional approach helps clients reverse melasma, slow accelerated aging, and restore skin health by supporting the body as a whole—not fighting it.     Want to watch this episode on YouTube? Click here. Subscribe if you'd like to catch all new episodes live and participate with our guests directly.   Want to learn more about becoming an FDN? Go to fdntraining.com/resources to get our best free workshops and mini-courses!

    Why Meds Aren’t the Answer—And What Is w/ Alisa Berteau

    In this episode, Detective Ev sits down with Alisa, a Doctor of Pharmacy with over 25 years of experience who made the courageous leap from conventional medicine into the world of functional health. After years of dispensing medications to manage symptoms, Alisa began to question the system—and her role in it. What she discovered changed everything. Alisa opens up about her personal and professional journey, including the stress, burnout, and gut health crisis that led to an emergency room visit in 2023. That wake-up call forced her to prioritize her own health and ultimately guided her toward becoming a Functional Diagnostic Nutrition® (FDN) Practitioner. Today, she’s on a mission to help others understand how deeply lifestyle choices impact the body—and how true healing happens when we address root causes, not just diagnoses. This conversation explores the powerful shift from a pharmaceutical mindset to a functional, lifestyle-based approach, emphasizing how everything in the body is connected. Alisa breaks down why focusing on DRESS (Diet, Rest, Exercise, Stress Reduction, and Supplementation) is foundational for long-term health and why having real data about how your body is functioning can be truly life-changing.     Want to watch this episode on YouTube? Click here. Subscribe if you'd like to catch all new episodes live and participate with our guests directly.   Want to learn more about becoming an FDN? Go to fdntraining.com/resources to get our best free workshops and mini-courses!
