Women Are Not Small Men! Why Fitness Advice Is Failing Half the Population | Dr. Stacy Sims

Author: Dr. Mark Hyman May 13, 2026 Duration: 1:23:04
Most health and fitness advice for women is based on research done in men. That’s something we need to rethink. On this episode of The Dr. Hyman Show, I sit down with Dr. Stacy Sims, an exercise physiologist and leading researcher in women’s health. Her work has focused on how female physiology actually changes over time—and how training and nutrition need to change with it. Watch the full conversation on YouTube, or listen wherever you get your podcasts. We explore: • Why eating less and doing more cardio can make fat loss harder • What actually changes in your metabolism in your 30s and 40s • How to train for strength—and why it matters for long-term health • Why most workouts aren’t building muscle (and what to do instead) • How to eat and time protein to support recovery, energy, and better sleep A lot of the advice women have been given doesn’t account for how the body actually changes. Adjusting how you train and eat can make a meaningful difference in your energy, strength, and long-term health.
