Fatigue, brain fog, joint pain, blood pressure that won’t budge, these aren’t isolated symptoms. They’re your cells signaling that something’s off.

In this episode of Extend, I sit down with Dr. Bill Rawls, a board-certified OB/GYN who now focuses entirely on cellular health. We explore why most chronic illness isn’t about your diagnosis, it’s about what’s happening inside your cells.

We share the five things every cell needs to function, and what happens when they don’t get them. We also dig into stealth infections like Lyme and Epstein-Barr, and how they stay dormant for years until your body breaks down.

Most importantly, we talk solutions: why herbs work when antibiotics don’t, how to support your immune system without overstimulating it, and what real healing looks like.

Dr. Bill Rawls is a board-certified physician and author of The Cellular Wellness Solution. His personal health crisis with chronic Lyme led him to develop Restore180, a protocol that’s helped thousands recover from chronic illness by restoring cellular function.

Your doctor says your health problems are genetic, so you're destined for the same fate. But what if that's completely wrong?

In this episode of Extend, I'm joined by Professor Tim Spector, one of the world's leading microbiome researchers, to reveal the truth: your gut bacteria have more control over your health than your genes do.

We explore Tim's 30-year twin study that turned modern medicine upside down, the devastating effects of antibiotics on your internal ecosystem, and why ultra-processed foods are as dangerous as cigarettes. We also dive into why 95% of Americans are dangerously fiber-deficient, and how fermented foods can reduce inflammation like natural steroids.

Professor Tim Spector is a genetic epidemiologist at King's College London, co-founder of Zoe, and author of multiple bestselling books on the microbiome. His research on 16,000 twins has revolutionized our understanding of how gut health trumps genetics in determining health outcomes.

In this episode of Extend, I’m joined by Dr. Robin Berzin, founder of Parsley Health, and we dig into how functional medicine uncovers the why behind your symptoms and why conventional care keeps missing it.

We talk about the most overlooked root causes of chronic illness, the truth about blood sugar and hormones, and why fertility issues are often metabolic in disguise. You’ll also learn how functional medicine works in real life, how to find the right provider, and why Dr. Berzin created her “brains, bones, and booty” framework for aging well—especially for women.

What if the root cause of burnout, inflammation, and hormone dysfunction isn’t just physical—but energetic?

In this episode of Extend, I sit down with Dr. Pedram Shojai—Taoist monk, doctor of Oriental medicine, and author of The Urban Monk—to explore how ancient wisdom meets modern health. We unpack why true healing requires addressing your qi (life force), how emotional stagnation leads to physical disease, and why regulating your energy is just as important as optimizing your bloodwork.

From the microbiome to meditation, Dr. Pedram shares how restoring energetic flow can radically shift your metabolism, mood, and even your fertility. And we go deep on what most functional medicine still misses about the connection between spiritual vitality and long-term health.

Dr. Pedram Shojai is a former Taoist monk, acclaimed filmmaker, and best-selling author who’s helped millions reconnect with their body, breath, and purpose. His work bridges ancient healing systems with today’s most pressing health challenges.
