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.

What if the real reason you’re gaining weight, feeling wired, or struggling to nourish your family isn’t about willpower—but the culture you live in?

On this episode of Extend, I’m joined by Shawn Stevenson—nutritionist, bestselling author, and host of The Model Health Show—to explore how our food environment, not personal discipline, is fueling the chronic disease crisis. If you’re raising kids, trying to eat better, or just feel overwhelmed by ultra-processed foods, this conversation cuts through the noise.

We unpack the science behind shared meals, how family dinner regulates your stress hormones, why many “healthy” foods aren’t, and what it takes to create a home culture that supports real health.

Shawn Stevenson is a bestselling author, nutritionist, and the creator of The Model Health Show, which has ranked as the #1 health podcast in the U.S. He’s the author of Eat Smarter and The Eat Smarter Family Cookbook, blending nutrition science with practical strategies for home-cooked meals that heal.
