    Dr. Laura Briden - This Is The Biggest Health Crisis Of Our Time

    Today I’m joined by Dr. Lara Briden, a naturopathic doctor, best-selling author, and internationally recognized expert in women’s hormones for a wide-ranging conversation on cycle health and why ovulation is a vital sign of wellbeing. We talked about how monthly ovulation creates hormones that support bones, metabolism, and brain function, and what happens when that rhythm is disrupted by stress, restrictive eating, or birth control. Dr. Briden explains why natural estradiol and progesterone are so protective, how they differ from synthetic hormones, and what that means for both younger women and women approaching perimenopause. She also shares her perspective on missing periods, hypothalamic amenorrhea, and the four functional types of PCOS, along with the growing role of insulin resistance in hormone imbalance. We talk about how to track ovulation, what lab markers to look for, and why restoring cycles is one of the most powerful steps for long-term health.

    Brigid Titgemeier, a functional medicine dietitian and founder of Being Brigid Nutrition, has seen countless women walk into her clinic exhausted, bloated, and frustrated despite eating all the right foods.

    Dr. Matt Kaeberlein, PhD - Why We Age + Interventions to Slow Aging

    What if aging wasn’t just something that happens to us, but something science could actually slow down? That’s the question at the heart of today’s conversation with Dr. Matt Kaeberlein, who’s a leading scientist and longevity researcher at the University of Washington. Dr. Kaeberlein has spent decades decoding the biology of aging, from cellular mechanisms to practical strategies that could extend not just how long we live, but how well we live. In this episode, we talked about surprising connections between aging and brain health, and looked into the research around lithium and Alzheimer’s to see what the latest science is telling us about extending healthspan.

    Exploring Metabolic Health with Nick Norwitz, MD, PhD

    In this conversation, I sit down with Nick to unpack the deeper science behind GLP-1s and metabolic health. We explore how compounds like Tirzepatide and GLP-1 agonists go beyond weight loss, influencing everything from cardiovascular elasticity and neuroinflammation to mood, cognition, and gut-brain signaling. We also discuss lesser-known drivers of real change, like adiponectin, MPO, and the surprising effects of statins on inflammation.But the conversation doesn’t stop with human health. We dive into the behavioral power of the microbiome, how dogs might reduce childhood allergies, and whether AI can actually translate what your pet is thinking. If you’re curious about fat loss, brain health, and the future of metabolic science, this episode offers a perspective you won’t find anywhere else.*Chapters:*0:00 – Meet Dr. Nick: From Patient to Pioneer06:50 – The Problem with "Evidence-Based Medicine"10:15 – Why Nick Left the Medical System13:10 – Can YouTube Have a Bigger Impact Than Hospitals?16:30 – What Is Metabolic Health & Why Does It Matter?19:00 – Mental Health, Depression & Metabolism24:15 – Brain Hacks That Actually Work40:00 – Improving Metabolic Flexibility Naturally46:00 – Gut-Brain Connection & Fiber Myths*Nick's Socials + Website*IG: https://www.linkedin.com/in/nicknorwitz/Youtube channel: https://www.youtube.com/channel/UCLTZUJSEulehPtF_ytFiU_AWebsite: https://www.nicknorwitz.com*Kayla's Socials + Website*Instagram: https://www.instagram.com/kaylabarnes/TikTok: https://www.tiktok.com/@femalelongevityTwitter: https://x.com/femalelongevityWebsite: https://www.kaylabarnes.comFollow Her Female Protocol: https://www.protocol.kaylabarnes.comBecome a Member of Kayla's Female Longevity Membership: https://kayla-barnes-lentz.circle.so/checkout/become-a-member
