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.

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. We’re changing that.

Every episode brings evidence-based, experience-backed conversations on strength, metabolism, hormones, longevity, and performance: for women, by women who’ve dedicated their careers to getting it right. No trends. No shortcuts. Just the proof that practice works.

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.
