Clockwork Hormones: How Your Circadian Rhythm Shapes Fertility & Period Health with Jillian Greaves, RD/N
This week on the Nourishing Women Podcast, we’re diving deep into the powerful (yet often overlooked) connection between your circadian rhythm and hormonal health. I’m joined by Jillian Greaves, a functional medicine dietitian and women’s health expert who specializes in root-cause approaches for hormone imbalances, PCOS, fertility, and gut health.
Jillian Greaves is a Functional Dietitian and Women's health specialist, the owner of the private practice Jillian Greaves Functional Nutrition & Wellness, and the creator of the PCOS Root Reversal Program. Jillian provides comprehensive nutrition and lifestyle counseling to women, with a special emphasis on PCOS, fertility, hormone balance, and digestive health. Jillian and her team help women identify and address the root causes of their hormone and digestive symptoms using advanced lab testing, personalized nutrition, and supportive lifestyle therapies as the first line of intervention. It's her mission to empower women to take back control of their health, reclaim their confidence, and to experience life at its fullest potential.
Jillian brings the science with so much clarity and care as we explore:
What your circadian rhythm actually is—and why it's not just about sleep.
How light exposure (hello, morning sun!) and meal timing influence your hormonal cascade.
Why syncing your body with your environment supports ovulation, mood, digestion, and metabolism.
How modern lifestyle habits—think: late-night screens, inconsistent meals, chronic stress—disrupt your hormone signaling.
Actionable tips you can start today to restore rhythm and reclaim your cycle.
Plus, we both share how our own personal experiences with hormonal birth control, period loss, and burnout led us to this work—and why we’re so passionate about helping you skip the years of trial-and-error we went through.
If you're navigating period loss, fertility challenges, or simply want to support your hormones more naturally, this episode is your reminder that foundational changes—like syncing with your body’s natural rhythm—can be game-changing.
