    Dr. Dawn Mussallem, DO: Cancer Prevention, Early Detection, Exercise, Metabolic Health and Breast Cancer Screening
    Apr 30 2026
    In this episode, I’m joined by Dr. Dawn Mussallem, DO, an integrative oncologist, lifestyle medicine specialist, cancer survivor, heart transplant recipient, and the newly appointed Chief Medical Officer of Fountain Life.We talk about why cancer rates are rising, what we actually know about prevention, and why early detection matters so much when it comes to long-term outcomes. We also discuss the role of exercise, sleep, fiber, metabolic health, toxins, alcohol, gut health, screening tools, mammograms, full-body MRI, liquid biopsies, and why the basics still matter more than most people want to admit.Dr. Dawn also shares her extraordinary personal story: She is a stage 4 cancer survivor who went through chemotherapy and a bone marrow transplant at 26, developed cardiac toxicity from treatment 18 years later, received a heart transplant, and became the first person in the world to run a marathon within a year of receiving a new heart.

  • GLP-1 Crisis for Women, Gut Health, Bone Loss with Dr. Sara Szal, MD

    GLP-1 Crisis for Women, Gut Health, Bone Loss with Dr. Sara Szal, MD
    Apr 16 2026
    We're back with Dr. Szal! Today we are discussing a variety of topics: Gut health, peptides, hormone health , GLP-1's, bone health and so much more!In this conversation, Dr. Sara G dives into the gut-brain connection and explains how disrupting the microbiome can directly affect mood, anxiety, and overall mental resilience. She breaks down why even a single course of antibiotics can shift the balance of your gut in ways most people never consider, and what that means for how you feel day to day.This is where the gut-brain connection becomes practical, not theoretical. Instead of treating symptoms in isolation, understanding how the microbiome regulates neurotransmitters and inflammation changes the way these issues are approached.Rebuilding that system requires more than random probiotics or diet changes. The Weed, Seed, Feed framework focuses on restoring gut balance in the right order, removing what doesn’t belong, reintroducing beneficial bacteria, and supporting their growth long-term.This episode is sponsored by Zen Basil. Their certified edible basil seeds are designed for human nutrition, deliver 15g of fiber per serving, and are batch-tested for glyphosate and over 400 pesticides.
