Why Women Are Twice as Likely to Get Alzheimer's and What To Do About It | Sandy Gleysteen

Sandy Gleysteen, award-winning journalist turned Alzheimer’s advocate and Chief Communications Officer at the Women’s Alzheimer’s Movement (WAM), joins us to unpack why women bear a disproportionate share of Alzheimer’s risk and what can actually be done about it. The conversation covers the critical role of estrogen as a neuroprotector, the window of opportunity around perimenopause and HRT, and the surprising finding that up to 50% of Alzheimer’s cases may be preventable through lifestyle. WHAT WE EXPLORE * Why two-thirds of Alzheimer’s cases are women, and the estrogen connection * Perimenopause as a critical window for brain protection and HRT timing * Up to 50% of Alzheimer’s cases may be preventable with lifestyle changes * Exercise and nutrition as first-line defenses against cognitive decline * How poor sleep allows amyloid plaques to build up in the brain * Why loneliness is as damaging to brain health as smoking two packs a day * The APOE4 gene test: should you get tested, and what to do with results * Creatine for women: brain and body benefits that outpace the research on men * Statins, cholesterol, and a critical open question no one is answering yet * Practical caregiving strategies when someone you love has dementia ABOUT DR SANDY GLEYSTEEN: Sandy Gleysteen spent decades as an Emmy Award-winning television producer at NBC and CBS, partnering with Maria Shriver on some of the most significant women’s journalism of a generation. After witnessing multiple family members navigate memory loss, she earned a Master’s in Gerontology from USC at age 67 and pivoted her career entirely to brain health advocacy. She now serves as Chief Communications Officer at the Women’s Alzheimer’s Movement, co-founded by Maria Shriver, and plays a central role in expanding WAM’s research grant program and the Women’s Alzheimer’s Prevention Center at Cleveland Clinic.

Body Composition, Muscle & Hormones: The Gap Between Research and What Actually Works | Proof of Practice

Dr. Stacy Sims, Dr. Gabrielle Lyon, Dr. Abbie Smith-Ryan, Gabby Reece, and Amber Taylor dive into one of the most urgent conversations in women’s health: how to make sense of body composition data, build muscle that actually matters, and navigate the exploding landscape of hormone replacement therapy. They challenge the idea that you need expensive testing or hours in the gym to make meaningful progress, revealing that simple bodyweight circuits, walking, and two resistance sessions a week produced real results in perimenopausal women.The conversation gets candid about HRT delivery methods, including a clear consensus against pellets, and a practical breakdown of what hormone bloodwork every woman should get at baseline. This is the episode you will want to send to every woman in your life who is tired of one-size-fits-all advice. WHAT WE EXPLORE * What a DEXA scan actually measures (and what it misses about your muscle) * Visceral fat vs. body fat: why the distinction matters for metabolic health * Body composition tracking tools for women who cannot access a DEXA * How perimenopausal women lost body fat with just walking and bodyweight training * Strength training for beginners: why you do not need a gym or heavy weights * 15-minute workouts that actually move the needle for busy women * How to navigate conflicting health research without losing your mind * Menopause hormone therapy: patches, pellets, injections, and what the experts actually use * The exact hormone panel every woman should get before starting HRT * Why taking personal ownership of your health is the ultimate non-negotiable Timestamps: * 00:00 Why Women’s Health Research Has Failed (And What’s Changing) * 01:10 What DEXA Scans Actually Measure — And What They Miss * 04:10 Why Skeletal Muscle Is Your Most Important Metabolic Organ * 07:30 DEXA vs. Scales vs. Waist-Hip Ratio: What to Use and When * 09:00 Why You Should Trust How You Feel Over Your Data * 12:45 You Don’t Need a Gym or Heavy Weights to Build Muscle * 15:00 The 15-Minute Home Circuit Busy Women Can Actually Stick To * 18:30 Why Health Advice Is So Conflicting — And How to Filter It * 23:30 How to Read Research Without Getting Misled or Overwhelmed * 32:00 HRT Delivery Methods Explained: Patches, Pellets, Injections, and Creams * 41:30 The Exact Blood Panel Every Woman Should Get Before Starting HRT * 47:00 How to Build a Health Plan That Works for Your Real Life – ABOUT THE PROOF OF PRACTICE The Proof of Practice: Where Science Meets Practice Hosted by five of the most respected names in women’s health: Dr. Abbie Smith-Ryan, Amber Taylor, Gabby Reece, Dr. Gabrielle Lyon, and Dr. Stacy Sims, this show exists because women have been studied less, treated as afterthoughts, and given advice built for men.

Stanford Doctor: Why Active Women & Female Athletes Are Damaging Their Bone Health

Bone health for female athletes is one of the most under-discussed topics in women's health, and what you don't know right now could follow you all the way into perimenopause. Dr. Emily Kraus, Sports Medicine Physician and Director of the FASTR (Female Athlete Science and Translational Research) program at Stanford University, joins us to dig into one of the most overlooked areas of women's health: bone density, bone stress injuries, and the hidden epidemic of Relative Energy Deficiency in Sport (RED-S). Dr. Kraus breaks down exactly why female athletes are at disproportionately high risk for bone stress injuries and how under-fueling, even when unintentional, can trigger hormonal suppression, menstrual cycle dysfunction, and long-term skeletal consequences. The conversation spans everything from iron deficiency and foot strike hemolysis to the surprising relationship between estrogen, strength training, and bone building across the lifespan. If you think bone health is only a concern after menopause, this episode will completely reframe how you think about your body at every age. What we explore: - What RED-S is and why it affects far more women than anyone is diagnosing - Why female athletes are at higher risk for stress fractures than male athletes - The silent signs of under-fueling that appear long before you lose your period - Fasted training and young female athletes: why skipping breakfast is not neutral - Iron deficiency in active women: how to test it, which form to take, and why runners are especially vulnerable - Jumping vs. running for bone health, and how to ease into plyometrics safely - How perimenopause accelerates bone loss and what you can actually do about it - Why hormonal contraception can mask RED-S and complicate the clinical picture - Estrogen and bone health: the case for transdermal estrogen in certain athletes - Strength training for bone density: why muscle quality matters just as much as bone density scores - Wearables and the future of early detection for overtrained, under-fueled athletes - Why sleep is a non-negotiable part of bone recovery for athletes at every age About Dr. Emily Kraus: Dr. Emily Kraus is a sports medicine physician and researcher at Stanford University, where she directs the FASTER Program: Female Athlete Science and Translational Research. Her work is focused on closing the gender gap in sport science by producing rigorous research and translating it into real-world clinical tools. She splits her time between treating athletes and leading research on bone health, energy availability, and the female hormone system across the athletic lifespan. She's one of the clearest, most practically minded voices working at the intersection of performance and women's health.
