Ep. 509 We’ve Been Ignoring This Vital Sign – The Most Powerful Tool to Track Hormonal Health with Dr. Mariza Snyder

Today, I am thrilled to reconnect with a friend and colleague, Dr. Mariza Snyder, to discuss her new book, The Perimenopause Revolution.  In our conversation, we explore some of the most pressing challenges around aging, including shame in a youth-obsessed culture, the lack of research on women’s health, and the physical toll of the aging process. We explain why the menstrual cycle should be considered a fifth vital sign, and what happens when metabolic health begins to decline in midlife, highlighting the value of apps and technology in empowering women to track their cycles. Dr. Mariza clarifies why biometrics, VO₂ Max, DEXA scans, and grip strength matter. She also shares her core pillars of metabolic health and the non-negotiables she believes make the most difference for women navigating the perimenopause-to-menopause transition. I truly enjoyed Dr. Mariza’s book, and I know it will be a powerful resource for women who want to take charge of their metabolic health during perimenopause and beyond. IN THIS EPISODE, YOU WILL LEARN: How hormonal shifts in midlife can alter energy, mood, and metabolism in unexpected ways Changes that ripple through sleep, stress, and cognition during perimenopause Why, in perimenopause, old diet and exercise strategies often stop working the way they used to  How cultural messages around aging fuel shame and confusion for women How DEXA scans reveal much more about your body composition than weighing yourself does What lab work can reveal about hidden risks  Why you should consider doing bone and muscle scans early in life The benefits of daily strength training for maintaining vitality and independence How regular movement stabilizes energy and glucose levels Why food choices become a critical foundation during midlife transitions Bio:  Dr. Mariza Snyder is a powerhouse advocate for midlife women, leveraging 17+ years as a practitioner, author, and speaker to spark a massive movement for women in perimenopause and beyond.
