BONUS: Is Obesity Really Genetic? Debunking the Myths with Dr. Ken Berry

Today, we have another episode in a series of conversations with experts and highly vetted companies. In this episode, we feature CocoaVia, a brand of cocoa flavanol supplements made from a proprietary cocoa extract that aims to support cognition and heart health. I am delighted to welcome Dr. Amy Shah, who trained at Cornell, Harvard, and Columbia. Dr. Shah is a well-known expert on metabolic health and intermittent fasting. With a background in internal medicine, allergies, and immunology, she has helped many patients transform their health with cutting-edge nutritional and medical science.  In our conversation, we explore cocoa flavanols, explaining what they are, their benefits, and how they work mechanistically. We discuss how perimenopause and menopause can lead to endothelial dysfunction due to low sex hormones, and the effects of lifestyle factors like circadian rhythm alignment. Dr. Shah shares foods she finds particularly helpful for middle-aged women and reviews the research on cocoa flavanols. We also cover the impact of cocoa flavanols on health span, longevity, and brain health, including improvements in memory, word recall, and spatial reasoning, and Dr. Shah offers guidance on supporting the maturation and health of teens and young adults. Today’s conversation with Dr. Shah is practical and evidence-based. I also share how cocoa flavanols have helped my younger son’s focus and attention, and how my husband and I use these products in our daily lives. IN THIS EPISODE, YOU WILL LEARN: How cocoa flavanols support heart health, brain health, and longevity Why nitric oxide production matters for vascular flexibility, especially in perimenopause How circadian rhythm optimization improves energy, mood, and metabolic health Why introducing fiber and probiotic foods slowly may be necessary for gut adaptation How cocoa flavanols and other bioactives can enhance health span and lifespan The importance of selecting the right supplement quality and dose to prevent ineffectiveness or excess How cocoa flavanols can improve cognition, memory, and brain function over 8–12 weeks Why natural drinks (coffee, cocoa flavanols) are far better than energy drinks or caffeine for teens How combining core lifestyle habits with targeted bioactive compounds supports long-term health and longevity Connect with Cynthia Thurlow   Follow on X Instagram LinkedIn Check out Cynthia’s website Submit your questions to support@cynthiathurlow.com Connect with Dr. Amy Shah On her website CocoaVia

As a nurse practitioner, I feel a deep responsibility to my listeners and community to ensure that every guest I bring on shares accurate, evidence-based information. A few months ago, I decided to remove two podcasts from earlier this year to make way for an expert who could speak specifically and authoritatively on breast cancer health. So, I am honored to welcome Dr. Robin Roth today, better known as The Boobie Docs, on her popular breast health social media platform, where she shares information about breast cancer in a fun and educational way.  Dr. Roth is an associate professor of radiology, specializing in breast and abdominal imaging. She is also the host of The Girlfriend's Guide to Breast Cancer podcast, created to support those navigating a breast cancer diagnosis or caring for a loved one. In our discussion today, we dive into misinformation about breast health and breast imaging. We explore the importance of acknowledging disinformation on social media, risk factors for early breast cancer screening, significant and modifiable risk factors, and the effects of dense breast tissue. We examine breast imaging, exploring ultrasound and mammography, the differences between 2D and 3D mammograms (the gold standard), and when to use MRIs. We clarify why thermography and QT imaging are not the gold standard, and why we need to request different types of imaging modalities. We discuss the importance of screenings, challenges, including diagnoses like DCIS, personalized approaches to breast cancer screening, breast cancer staging, and issues with imaging after mastectomies and with implant placement. Dr. Roth also explains how 80% of breast biopsies end up being benign, how to manage anxiety and callbacks for mammograms, how to understand lab reports in plain language terms, and the benefits of supportive resources like cancerbesties.com. With her expertise and approachable style, Dr. Roth reminds us that proper information can make all the difference when it comes to breast health. You will not want to miss this conversation, especially during Breast Cancer Awareness Month. IN THIS EPISODE, YOU WILL LEARN: How online platforms fuel confusion around breast health and imaging Disinformation may influence breast cancer screening decisions Modifiable factors that can reduce or increase your risk of breast cancer Why dense breast tissue matters for imaging accuracy Ultrasounds, 2D and 3D mammograms, and MRIs  Thermography and QT imaging are not gold standards Why every individual DCIS diagnosis needs a personalized approach Breast cancer staging and how it guides treatment 80% of biopsies are benign, but still essential How to manage anxiety around callbacks and make sense of lab reports Connect with Cynthia Thurlow   Follow on X Instagram LinkedIn Check out Cynthia’s website Submit your questions to support@cynthiathurlow.com Connect with Dr. Robyn Roth On her website Social Media: @the boobie docs Preorder a copy of Everyone Has Boobies
