Longevity Optimization with Kayla Barnes-Lentz

Women don’t fail January — January fails women. Nearly 80% of New Year health goals are abandoned within weeks, not because of discipline, but because most plans ignore female biology. That’s why I created the 30-Day Female Longevity Challenge — a physiology-first way to prepare calmly and build health that actually lasts.

For years, functional medicine has focused on lab results and supplement protocols. Dr. Deanna Minich knows there's a deeper layer most practitioners miss. As a nutrition scientist who worked under Dr. Jeffrey Bland and educated for the Institute for Functional Medicine, she's witnessed how artificial light at night disrupts women's hormones more than almost any other factor, yet it's completely ignored.In this episode, Dr. Minich reveals why 85% of people are Omega-3 deficient despite supplementing, how eating a rainbow of 30+ plant species weekly rebuilds your microbiome diversity, and why your skin's "photo-metabolome" produces healing compounds from sunlight that Vitamin D pills can never provide. She explains the Goldilocks principle of sun exposure, why most women only get 11-15 grams of fiber daily when they need triple that, and how stress functions as a toxin that triggers leaky gut and impairs detoxification. Dr. Minich also shares why women's heightened sensitivity isn't a weakness but a powerful gift for intuition and healing.If you're tired of functional medicine that stops at labs and supplements, this conversation offers a comprehensive framework integrating circadian optimization, creative expression, gut diversity, and the spiritual aspects of women's health that determine true longevity.Guest’s socials + websiteInstagram: https://www.instagram.com/deannaminich/Website: https://deannaminich.com/Kayla's social + website:Instagram: https://www.instagram.com/kaylabarnes/TikTok: https://www.tiktok.com/@femalelongevityTwitter: https://x.com/femalelongevityWebsite: https://www.kaylabarnes.com/Follow Her Female Protocol: https://www.protocol.kaylabarnes.com/Become a Member of Kayla's Female Longevity Membership: https://kayla-barnes-lentz.circle.so/checkout/become-a-member

Everyday “healthy” choices might be silently rewiring your immune system—from canned soup and tap water to perfume, makeup, and even your couch—while autoimmune diseases quietly explode, especially in women. In this gripping conversation, Dr. Aly Cohen reveals how under-regulated chemicals, hidden toxins, and epigenetic changes may be driving the autoimmune epidemic, but also how strategic swaps, smarter water, food, air, and a 4-A framework can actually change the destiny of your health. If you’ve ever wondered whether you can truly detox, reverse flares, and protect future generations, this episode turns overwhelming science into a suspenseful, empowering roadmap.Join the most comprehensive female-specific community for health and longevity optimization.
