In this conversation, I sit down with Nick to unpack the deeper science behind GLP-1s and metabolic health. We explore how compounds like Tirzepatide and GLP-1 agonists go beyond weight loss, influencing everything from cardiovascular elasticity and neuroinflammation to mood, cognition, and gut-brain signaling. We also discuss lesser-known drivers of real change, like adiponectin, MPO, and the surprising effects of statins on inflammation.But the conversation doesn’t stop with human health. We dive into the behavioral power of the microbiome, how dogs might reduce childhood allergies, and whether AI can actually translate what your pet is thinking. If you’re curious about fat loss, brain health, and the future of metabolic science, this episode offers a perspective you won’t find anywhere else.*Chapters:*0:00 – Meet Dr. Nick: From Patient to Pioneer06:50 – The Problem with "Evidence-Based Medicine"10:15 – Why Nick Left the Medical System13:10 – Can YouTube Have a Bigger Impact Than Hospitals?16:30 – What Is Metabolic Health & Why Does It Matter?19:00 – Mental Health, Depression & Metabolism24:15 – Brain Hacks That Actually Work40:00 – Improving Metabolic Flexibility Naturally46:00 – Gut-Brain Connection & Fiber Myths*Nick's Socials + Website*IG: https://www.linkedin.com/in/nicknorwitz/Youtube channel: https://www.youtube.com/channel/UCLTZUJSEulehPtF_ytFiU_AWebsite: https://www.nicknorwitz.com*Kayla's Socials + Website*Instagram: https://www.instagram.com/kaylabarnes/TikTok: https://www.tiktok.com/@femalelongevityTwitter: https://x.com/femalelongevityWebsite: https://www.kaylabarnes.comFollow 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

This episode is brought to you by OneSkin, the longevity scientists behind the first topical peptide scientifically proven to reverse skin aging—now bringing their expertise to your scalp.

If you care about aging well, you can’t ignore your hair. The health of your scalp directly impacts the strength, thickness, and lifespan of every strand.

That’s why OneSkin created their new OS-01 HAIR, the first scalp serum powered by a longevity peptide designed to optimize follicle health, balance the scalp, and extend the healthspan of your hair follicles.

In their clinical study, OS-01 HAIR showed significant improvements in hair density, thickness, and overall scalp health—all by targeting follicle aging at the root.

I’ve been using it myself and I’m genuinely impressed. It’s lightweight, fragrance-free, and backed by science—not fluff.

If you're serious about keeping your hair vibrant and resilient as you age, I highly recommend giving OneSkin's OS-01 HAIR a try.
