The Science of Sex-Specific Nutrition and Biohacking with Stacy Sims

Optimal nutrition is different from person to person, and even more so from sex to sex. Men and women have many physiological differences that can truly change how to approach health and fitness.

Are cold plunges good for men and women? What about saunas?

Dr. Stacy Sims – a forward-thinking international exercise physiologist and nutrition scientist – is the guest of today’s episode, and we explore the physiological differences between male and female bodies and reveal how you can optimize your nutrition and training based on your unique needs.

We dive deep into specific vitamins and minerals, the difference in heat retention and how that affects health, and we discuss whether some biohacking methods – like cold plunges and saunas – are more optimal for one sex.

Stacy Sims has 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. Her contributions to the international research environment and the sports nutrition industry have established a new niche in sports nutrition; and established her reputation as the expert in sex differences in training, nutrition, and health.

People who are serious about their health are a different breed of people. We try weird stuff. We don’t blindly trust what “they” tell us. People usually think we’re a little crazy.
