We talk a lot about hormones, blood sugar, and gut health on this show, but there's a layer underneath all of it that rarely gets its own spotlight: what's actually happening inside your cells. That's exactly where this conversation with Dr. Will Cole goes, and it completely shifted how I think about aging, energy, and chronic disease.
Dr. Cole is a functional medicine practitioner and the New York Times bestselling author of Intuitive Fasting, Ketotarian, The Inflammation Spectrum, and Gut Feelings. His newest book, Heal Your Cells, co-authored with Dr. Josh Axe, digs into what happens when our cells start aging faster than they should, and what we can actually do about it.
What Does It Mean for Cells to "Age Too Fast"?
The core idea behind Heal Your Cells is that a lot of what we chalk up to normal aging, or even to specific diagnoses, actually traces back to cellular dysfunction. Our cells are supposed to repair, regenerate, and communicate efficiently. When that process breaks down, the downstream effects show up as fatigue, brain fog, slower recovery, and eventually, chronic disease.
We talked about why this matters so much right now: cellular aging isn't just a concern for later in life. It's increasingly showing up earlier, which raises the question of why younger generations may be aging faster at the cellular level than previous ones did.
What We Covered: Mitochondria, Stem Cells, and More
This conversation covered a lot of ground, and I wanted to break down the key concepts we discussed:
- Mitochondria: Often called the powerhouse of the cell, and central to how much usable energy your body actually has available.
- Stem cells: Their role in regeneration and repair, and how that capacity changes as we age.
- Peptides: A growing area of interest in longevity work, and where the evidence is strongest.
- GLP-1: How this pathway fits into the broader conversation about metabolism and cellular health, beyond just weight loss.
- Methylation: The process your body uses to regulate gene expression, detoxification, and repair at a cellular level.
- Gut health: How the health of your gut microbiome influences inflammation and, in turn, cellular aging throughout the body.
- Circadian rhythm: Why the timing of your sleep, light exposure, and eating may matter just as much as the choices themselves.
If you've ever felt like you're doing "all the right things," eating well, moving your body, managing stress, and still not feeling your best, this episode offers a different lens to look through. Instead of chasing symptoms one at a time, Dr. Cole's framework asks a more foundational question: what does your body need to actually heal at the cellular level?
This is one of those conversations that connects so many dots between the topics we cover individually on this show, blood sugar, gut health, sleep, stress, and hormones, and shows how they all ultimately come back to the health of your cells.
