Most people think heart disease is just about cholesterol. But what if the real issue is in your genes, your environment, and even your daily stress?In this episode, I’m joined by Dr. Christopher Davis, a triple board-certified interventional cardiologist who’s redefining what it means to take care of your heart. After years of performing stent procedures, he realized the conventional system was only treating symptoms, not causes. So he made a bold shift from reactive cardiology to a root-cause approach that blends advanced testing, functional medicine, detoxification, and even ancient healing wisdom. We discuss how genetics determine whether saturated fats help or harm you, why cholesterol itself isn’t the enemy, and how inflammation and oxidative stress are the real threats to your arteries. If you’ve ever wondered why someone with perfect cholesterol can still have a heart attack, or why your stress levels matter just as much as your diet, this conversation will change how you think about cardiovascular health forever.Guest’s website + socials:Website: https://revealvitality.com/christopher-davis/Instagram: @cjdavismdKayla's social + website:Instagram: https://www.instagram.com/kaylabarnes/TikTok: https://www.tiktok.com/@femalelongevityTwitter: https://x.com/femalelongevity Website: https://www.kaylabarnes.com/Follow Her Female Protocol: https://www.protocol.kaylabarnes.com/Become a Member of Kayla's Female Longevity Membership: https://kayla-barnes-lentz.circle.so/checkout/become-a-member

Dr. Brad Schoenfeld, PhD is one of the world’s leading researchers on muscle hypertrophy (muscle growth). He is a Professor of Exercise Science at Lehman College in New York, where he directs the Human Performance Laboratory. Over his career, he has published more than 300 peer-reviewed articles, book chapters, and textbooks on resistance training, body composition, and nutrition.He is the author of Science and Development of Muscle Hypertrophy and The Max Muscle Plan, and has received prestigious honors such as the NSCA Young Investigator of the Year and the Dwight D. Eisenhower Fitness Award. Beyond academia, he has been a personal trainer and natural bodybuilding competitor, which allows him to uniquely bridge cutting-edge science with practical application.Here's what he knows: the fitness industry has been selling you the wrong story. Not maliciously, but confidently. And most people are paying the price without even realizing it.In this episode, Brad reveals why so many people are working harder than they need to while missing the basics that matter most. We discuss the beliefs keeping women from reaching their potential, the risks that sneak up when you avoid certain types of training, and what actually determines whether you stay strong and independent decades from now. He also tackles the myths around supplements, workout structure, and whether you're doing enough or too much.If you're ready to stop spinning your wheels and start training smarter, this conversation will show you exactly where to begin.Chapters:00:00 - Meet Dr. Schoenfeld & why strength training is vital for health07:00 - Metabolic health, bone density & preventing osteoporosis15:00 - Training for strength, hypertrophy & power (and busting myths)25:00 - Practical routines: how much volume, soreness, and recovery time34:00 - Glute growth, exercise variety & women’s training differences45:00 - Protein, fueling & the truth about creatineDr. Schoenfeld’s Social + WebsiteWebsite: https://www.lookgreatnaked.com/Instagram: https://www.instagram.com/bradschoenfeldphd/Kayla's Social + WebsiteInstagram: 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.com

For years, women have been told that birth control or IVF are the only solutions to reproductive issues. Dr. Naomi Whitaker knows that’s not the full story. Through Restorative Reproductive Medicine, she helps women identify the deeper health imbalances that fuel infertility, endometriosis, PCOS, and hormones, and shows how healing the body’s natural rhythms can change everything. In this episode, Dr. Whitaker reveals why standard lab ranges are often misleading, how cycle charting can act like a “health report card,” and why bioidentical hormone support is a game changer for energy, mood, and long-term vitality. She also shares her perspective on endometriosis surgery, PCOS subtypes, and the future of reproductive care.

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.Chapters00:49 - Ovulation as a vital sign of female health02:57 - Impact of hormonal birth control on ovulation and hormones07:51 - Benefits of natural estrogen and progesterone09:47 - Perimenopause and importance of hormones in young women11:49 - Benefits of estradiol and progesterone17:37 - Dysregulated or missing periods19:50 - Anovulatory cycles and tracking ovulation22:50 - Lag time for menstrual cycle disruption and recovery26:50 - Differentiating between hypothalamic amenorrhea and PCOS31:18 - Four different types of PCOS36:25 - Lab markers for insulin resistance58:53 - Recommendations for managing insulin-resistant PCOSDr. Briden socials + websiteWebsite: ⁠https://www.larabriden.com/about/⁠ Instagram: ⁠@larabriden⁠Kayla's social + website:Instagram: ⁠https://www.instagram.com/kaylabarnes/⁠TikTok: ⁠https://www.tiktok.com/@femalelongevity⁠Twitter: ⁠https://x.com/femalelongevity⁠ Website: ⁠https://www.kaylabarnes.com/⁠Follow Her Female Protocol: ⁠https://www.protocol.kaylabarnes.com/⁠Become a Member of Kayla's Female Longevity Membership: ⁠https://kayla-barnes-lentz.circle.so/checkout/become-a-member⁠
