Dr. Gabrielle Lyon, Dr. Stacy Sims, Dr. Abbie Smith-Ryan, Gabby Reece, and Amber Taylor build a practical, protein-forward nutrition framework rooted in the idea that muscle is the organ of longevity. They challenge outdated protein guidelines, break down protein quality, and cover the real-world barriers women face in actually hitting their targets, from fasted training and meal timing to snacking habits, carb strategy, and the underrated role of culture and liquid calories in derailing progress. WHAT WE EXPLORE * Muscle as the medical anchor: heart disease, PCOS, fertility, and sexual function * The sarcopenia epidemic and the role of GLP-1s, sedentary behavior, and low-protein diets * Muscle quality vs. muscle mass: why intramuscular fat may matter than body fat percentage * “Skinny fat” risk: why lean women can still have critically low muscle * Compound movement basics: frequency, load, and whole-body training structure * Protein targets: the 100g minimum, 1.6g/kg baseline, and meal timing * Why the 30/30/30 protein model may be leaving women under-fueled * Blood flow restriction: building muscle and staying active through injury * New perimenopause research: meaningful muscle gain in just 6 weeks * Strength training for cognition, mood, and resilience in midlife Timestamps * 00:00 Why Nutrition Is the Most Contested Topic in Women’s Health * 01:37 How to Adjust Your Eating by Season and Life Stage * 03:04 Muscle Is the Organ of Longevity: Why Protein Comes First * 04:20 Why the Official Protein Guidelines Are Wrong for Women * 05:20 Amino Acid Scores: Why Protein Quality Matters * 08:00 Combining Animal and Plant Protein Without the Guilt * 11:15 Soy, Protein Powders, and When Whole Food Wins * 13:49 Why Tracking Macros Keeps You From Eating Right * 17:28 Should Women Train Fasted? The Real Research Answer * 23:13 Why Your First Meal Is Your Most Important Protein Meal * 26:36 Snacking Habits That Quietly Undermine Your Progress * 33:32 How Many Carbs Women Actually Need (And When to Eat Them) * 40:25 Pre-Sleep Nutrition: Night Wakings, Hypoglycemia, and Active Women * 42:47 Liquid Calories, Food Guilt, and the Hidden Gaps in Your Diet * 44:57 There’s No One Right Diet: Building a Framework That Works for You – ABOUT THE PROOF OF PRACTICE The Proof of Practice: Where Science Meets Practice Women have been understudied, undertreated, and given advice built for men. This show exists to change that. 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 — every episode brings evidence-based, experience-backed conversations on strength, metabolism, hormones, longevity, and performance. No trends. No shortcuts. Just the proof that practice works.

A three-time NSCA award winner — including Outstanding Sports Scientist of the Year (2022) — she translates cutting-edge lab science into practical strategies that actually work for women across every life stage. 📷 Instagram: https://www.instagram.com/asmithryan/ 🌐 http://asmithryan.com Amber Taylor Amber Taylor is a New Zealand–based digital health and product leader who builds evidence‑based fitness platforms designed to better support women’s physiology, safety, and long‑term wellbeing. Drawing on two decades in technology and digital roles at Amazon, Nike, and Les Mills, she uses AI, behavioral insights, and omnichannel delivery to create inclusive training experiences that help women move consistently, recover smarter, and integrate exercise into real life. Dr. Gabrielle Lyon, DO Board-certified in family medicine and fellowship-trained in nutritional science and geriatrics, Dr. Gabrielle Lyon is the founder of muscle-centric medicine — a framework that positions skeletal muscle as the cornerstone of metabolic health, longevity, and disease prevention. She is the author of the bestselling book Forever Strong and one of the most sought-after voices in functional medicine and women’s performance. 📷 Instagram: https://www.instagram.com/drgabriellelyon/ 🌐 http://drgabriellelyon.com Dr. Stacy Sims, PhD Exercise physiologist and nutrition scientist Dr. Stacy Sims has spent her career closing the research gap on women in sport — making the case that women are not small men and should not be trained or fueled as such. She is the author of ROAR and Next Level, a two-time TEDx speaker, and the go-to expert on how hormones, training, and nutrition interact across the female lifespan, from athletic peak to perimenopause and beyond. 📷 Instagram: https://www.instagram.com/drstacysims/ 🌐 http://drstacysims.com JOIN THE PROOF OF PRACTICE COMMUNITY The conversation doesn’t stop when the episode does. 📷 Follow us for evidence-based clips and content that makes you feel less alone in what you’re going through. 👉 https://www.instagram.com/proofofpractice_/ 💌 Some things deserve more space than an episode allows.
