I am excited to connect with Dr. Lara Briden today! She is one of my favorite naturopathic doctors and the author of the bestselling books Period Repair Manual and Hormone Repair Manual. She has 25 years of experience in women's health, and she currently has consulting rooms in Christchurch, New Zealand, where she treats women with PCOS, PMS, endometriosis, perimenopause, and many other hormone- and period-related health problems. Dr. Briden is a wealth of information! She brings a fresh perspective and a positive voice to the health and wellness space, and I often recommend her book, Hormone Repair Manual, to my clients and patients.  Today, she and I dive into her background as an evolutionary biologist and discuss how she became passionate about supporting and advocating for women throughout their lives. We talk about perspectives on aging, what the second puberty (perimenopause) is, and the impact of histamine, mass-cell granulation, and estrogen. We discuss fat redistribution in middle age and the loss of insulin sensitivity. We speak about how using alcohol impacts brain health, sleep, the gut microbiome, appetite, cravings, and hinders estrogen metabolism. We also touch on ways to address dysfunctional uterine bleeding in middle age, explain how to advocate for your health, how middle age impacts the nervous system, and the role of inflammatory foods, including dairy.  I hope you enjoy our discussion as much as I did! Stay tuned for more! IN THIS EPISODE YOU WILL LEARN: Dr. Briden discusses her background as an evolutionary biologist and how she changed her career to become an advocate for women’s health. Many women fear the aging process. Dr. Briden and I discuss women’s mindsets and perspectives on aging.  Why is there so little awareness about perimenopause? Dr. Briden defines menopause and discusses the timeframe in which some women experience perimenopause symptoms. How can ongoing hormonal fluctuations during perimenopause, or second puberty, increase the likelihood of women having issues with a histamine response? Dr. Briden talks about fat redistribution in middle age and explains why women need to stay on top of it from a metabolic perspective. How can our modern-day lifestyle make the metabolic shift women experience in menopause even more challenging? Dr. Briden talks about natural treatments and hormone therapies to lighten the flow of the extremely heavy periods that some women experience during perimenopause. Dr. Briden discusses the connection between cow dairy and an inflammatory reaction in some people. Women need to understand what happens in their bodies when they have either a partial or a full hysterectomy. Dr. Briden talks about estrogen and brain health. How does alcohol affect the body? What are the best options with the fewest side effects for hormone therapy for women?

With over 45 years of experience healing adults from narcissistic, dysfunctional, and emotionally immature family systems, Jerry’s work guides people out of lifelong patterns of guilt, shame, and emotional enmeshment so they can finally live as their true selves.

We dive into narcissism, personality disorders, and the spectrum within which Jerry believes narcissism falls. We explore low, middle, and high-anxiety family systems, clarify why self-differentiation is critically important, and how long-term nervous system dysregulation often occurs when we grow up in narcissistic homes. We also cover trauma bonding, the impact of avoidance, the role of boundaries, and cultural myths around honoring our parents, and I answer some rapid-fire questions tailored explicitly to Jerry’s expertise. I have wanted to interview Jerry for the podcast for a long time, and this is one of those truly impactful and deeply personal episodes.
