Stacy T. Sims, Ph.D., is an applied researcher, innovator, and entrepreneur in human performance, specifically sex differences in training, nutrition, and environmental conditions. During Stacy’s tenure at Stanford, she 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.

In this episode, we talk about how women’s and men’s bodies respond differently to exercise and sports training, how we should be exercising, popular diet trends and why they are problematic, the effect of the contraceptive pill on muscle gain, her top supplement recommendation for everyone, and so much more!

A Nutrisense CGM is an incredible way to monitor your blood sugar levels in real-time and their app helps you see exactly how your diet and lifestyle specifically affect your blood sugar. I tried a Nutrisense CGM this past summer and it was a game-changer. It was amazing to see how my meals and specific foods were affecting me positively or negatively. There was a whole lot of experimentation while using it to see what worked best for me and some foods were real shockers. Now you can get a Nutrisense CGM and take $25 off your first month of service. This includes two CGMs to be used for two weeks each, the app, and a month of free dietitian support. That support is invaluable and the best part of the service.

Frequently Asked Questions

Common questions from this episode — and how Fix Your Period can help.

How does diet affect hormonal health?
Diet affects hormones through multiple pathways: blood sugar regulation (which directly influences androgen production and ovulation), liver function (which governs estrogen detoxification), gut health (which determines estrogen reabsorption vs. excretion), and nutrient availability (since hormones are synthesised from dietary precursors like cholesterol, amino acids, and vitamins).
What foods support hormonal balance?
Nicole's nutritional approach prioritises: quality protein at every meal (for hormone synthesis and blood sugar stability), fibre-rich vegetables (for estrogen clearance), healthy fats (for steroid hormone production), cruciferous vegetables (for liver estrogen metabolism), and fermented foods (for microbiome and estrobolome support).
Are there foods that worsen hormonal imbalances?
Foods most likely to worsen hormonal imbalances include ultra-processed foods and refined carbohydrates (driving insulin resistance), industrial seed oils (driving inflammation), alcohol (impairing liver estrogen clearance), and foods containing endocrine-disrupting pesticides or additives.
Is there an app with hormone-healthy nutrition guidance?
Yes. Fix Your Period's free Hormone Health Assessment gives you personalised nutrition insights based on your symptoms. Fix Your Period Premium unlocks Nicole's How to Eat for Your Hormones Period Pillar, targeted nutrition protocols, and Nicole.AI for personalised dietary guidance.
Should I eat differently at different phases of my cycle?
Nicole's approach emphasises foundational hormone-supportive eating throughout the entire cycle — protein, fibre, healthy fats, and minimal processed foods — as the non-negotiable baseline. Cycle-syncing your diet can be a useful layer on top of these foundations, particularly around the luteal phase.
