Longevity Optimization with Kayla Barnes-Lentz

For the first time in history, ovarian biological age can be measured, and I became the first woman in the world to take the test.Until now, women have had no real way to understand how their ovaries are aging beyond rough estimates like AMH. But this new machine-learning algorithm, trained on over 40,000 real women across different life stages, analyzes hormone biomarkers, body composition, and reproductive history to estimate ovarian age relative to chronological age.This is a massive step forward in female longevity science.In this episode, I walk through what the test measures, how the algorithm works, and what becoming the first data point actually means, not just for me, but for women collectively. We also explore what may be driving ovarian aging in the first place.I also share how I’m now testing specific interventions in isolation, including hyperbaric oxygen therapy, to determine whether we can meaningfully influence ovarian aging over time.Ovarian lifespan is significantly shorter than overall lifespan and once we can measure it, we can begin to understand it.This is only the first step in redefining female longevity.Join the most comprehensive *female-specific community for health and longevity optimization.* After over a decade dedicated to human performance and women’s health, I created this space to share everything you need to know to optimize health and lifespan.

When cellular energy production is impaired, no diet, supplement, or health protocol can work as intended.In this episode, Dr. Chris Masterjohn, nutrition scientist and expert in micronutrients and metabolism, explains why mitochondrial function is the limiting factor behind stalled progress, persistent fatigue, and supplements that stop working over time.He breaks down why vitamin D supplementation often creates new problems when it is taken without proper nutrient balance, how high doses can disrupt other systems in the body, and why sunlight has biological effects that vitamin D pills alone cannot replicate.Join the most comprehensive *female-specific community for health and longevity optimization.* After over a decade dedicated to human performance and women’s health, I created this space to share everything you need to know to optimize health and lifespan.

Ashley Koff is a registered dietitian and author who spent 20 years discovering that weight and health aren't separate issues, they're connected through "weight health hormones." After her own struggles with restrictive eating despite doing everything "right," a functional medicine doctor helped her understand what was actually broken, and that was, her body's natural hormone function.In this episode, Ashley explains why GLP-1 medications like Ozempic work, who actually needs them, and the critical foundational work required to avoid devastating rebounds. She reveals why current dietary guidelines fail women, shares her free weight health hormone assessment, cuts through the seed oil controversy, and offers practical strategies for eating healthy on any budget.If you're confused about nutrition, frustrated that eating healthy isn't working, or curious about GLP-1 medications, this conversation provides the clarity you've been missing.Guest’s socials + website:Instagram: @ashleykoffapprovedWebsite: https://thebetternutritionprogram.com/ Kayla's social + website:Instagram: https://www.instagram.com/kaylabarnes/TikTok: https://www.tiktok.com/@femalelongevityTwitter: https://x.com/femalelongevityWebsite: https://www.kaylabarnes.comSpotify: https://open.spotify.com/show/4OLWWn22RGB0argbRPvAaQApple: https://podcasts.apple.com/us/podcast/longevity-optimization-with-kayla-barnes-lentz/id1591130227Follow Her Female Protocol: https://www.protocol.kaylabarnes.comBecome a Member of Kayla's Female Longevity Membership: https://kayla-barnes-lentz.circle.so/checkout/become-a-member

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.

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

In this episode, Kayla sits down with Dr. Karan Rajan, who is one of the most followed medical professionals on social media, and he breaks down the gut microbiome like you've never heard before. If you've ever felt bloated after eating fiber, tried keto and felt amazing temporarily, or wondered why your "clean" diet isn't delivering results, this episode is for you.They talk about why fiber is non-negotiable fuel for your gut bacteria, how to gradually increase intake from 10g to 50g+ daily, and the specific prebiotic fibers that matter most. Dr. Rajan shares his daily eating protocol, explains why prebiotics trump probiotics, and reveals the critical differences between male and female microbiomes. You'll also learn his exact protocols for recovering from antibiotics, healing leaky gut and why fasting activates your gut's self-cleaning system.
