I’m here to empower you with the knowledge to cut through the noise.
I translate complex science into straightforward, actionable insights so that active women (like you!) understand how to build strength and longevity of both body AND mind.
WELCOME...

Hi, I’m Dr. Stacy Sims and I’m here to help active women and the people who work with them (coaches, physical therapists, parents, doctors, PhDs, allied health practitioners, teachers, and more) take back control of their lives, their bodies, and their health through better understanding backed by science.
I wrote my book, ROAR, and then created my signature course WOMEN ARE NOT SMALL MEN® because I saw the appalling lack of research done specifically on women in regards to exercise, nutrition, and medicine. This has expanded into a suite of courses (WANSM, Menopause 2.0, Next Gen), Microlearning, Articles, and books with more information and training to come.
“My vision is a world of healthy women who understand and know how to work with their bodies, cut through the taboo of periods and menopause, and create positivity around being a woman in sport.”

You have what it takes
You don’t have to be an athlete to benefit from what I have to share. You have what it takes to be an active woman who will challenge yourself in training and take action towards a stronger future.
I’m passionate about getting this information into the hands of as many active women as possible and my courses fund this advocacy work.
Why trust me?
In order to remain impartial and factual, I’ve built my business to be independent of outside influence. My work is funded entirely by sales of my courses and products.
There are no external pressures or agendas, just real, science-backed information that empowers you to take back control of your health & body through deep understanding of your physiology as a woman.
I conduct independent studies, collaborate with other like-minded scientists, and collate some research from reputable sources, which are documented on Google Scholar.

Experience
I’m a forward-thinking international exercise physiologist and nutrition scientist with an MSc and PhD. My aim is to revolutionize exercise nutrition and performance for women.
I have directed research programs at Stanford, AUT University, and the University of Waikato, focusing on female athlete health and performance and pushing the dogma to improve research on all women.
With the unique opportunities Silicon Valley has to offer, during my tenure at Stanford, I had the opportunity to translate earlier research into consumer products and a science-based layperson's book (ROAR) written to explain sex differences in training and nutrition across the lifespan. Both the consumer products and the book challenged the existing dogma for women in exercise, nutrition, and health. This paradigm shift is the focus of my famous "Women Are Not Small Men” TEDx talk.
My contributions to the international research environment and the sports nutrition industry have established a new niche in sports nutrition and solidified my reputation as the expert in sex differences in training, nutrition, and health.
I’ve published over 100 peer-reviewed papers and several books and am a regularly featured speaker at professional and academic conferences.
I currently hold a Senior Research Associate position with SPRINZ-AUT University, an adjunct position with the Stanford Lifestyle Medicine Group, supervise PhD students, write academic papers, and am on the advisory board of several cutting-edge companies.
Here, on www.drstacysims.com, I create and deliver online learning material focused on women training with their physiology across the lifespan.
