Did You Know Your Bones Affect Your Metabolism?
The Science of Self-Healing
You probably think of your bones as a frame that holds you up. But your skeleton is also sending hormones to your kidneys, pancreas, muscles, fat, and even your brain. In this episode of The Science of Self-Healing, we look at bone as an active, hormone-producing organ. You’ll learn how a bone hormone called FGF23 helps control phosphate and vitamin D, why researchers think osteocalcin may affect blood sugar, and how bone might even play a role in appetite. We’ll also cover why people with diabetes can break bones even when their scans look normal, how undereating and rapid weight loss,...

Is Berberine Really Nature's Ozempic? What the Science Says
The Science of Self-Healing
Berberine is all over social media right now, usually with the nickname "nature's Ozempic." But does this bright yellow plant compound actually live up to the hype? In this episode of The Science of Self-Healing, we look at what the research really says about berberine and your metabolism. You'll learn how it may help lower blood sugar and cholesterol, why so little of it reaches your bloodstream and yet it still seems to work, and how your gut bacteria play a surprising role in its effects. We'll also look at why the Ozempic comparison falls apart, what a 2026 clinical trial found about...

Can Rosemary Really Improve Your Memory?
The Science of Self-Healing
Could the scent of rosemary actually sharpen your memory? Rosemary has been associated with remembrance since antiquity, and centuries later, herbalists were describing it as an herb that could strengthen memory and the senses. Today, modern researchers are uncovering intriguing biological reasons that this enduring connection may be more than symbolic. In this episode of The Science of Self-Healing, Dr. James Odell explores how rosemary and its active compounds may influence memory, attention, alertness, brain energy, inflammation, oxidative stress, and the neurotransmitter acetylcholine....

The Biology of Aging: What Actually Changes and What Can We Control?
The Science of Self-Healing
What if aging isn’t simply a matter of getting older—but a complex biological process that we may have more influence over than we once thought? In this episode of The Science of Self-Healing, Dr. James Odell explores what actually happens inside the body as we age, from changes in our cells, mitochondria, hormones, immune system, microbiome, and epigenetics to the gradual shifts that occur in our muscles, bones, cardiovascular system, and brain. You’ll discover why people can age at remarkably different rates, how everyday factors such as movement, nutrition, sleep, stress, and social...

What Are GLP-1s Really Doing to Your Body?
The Science of Self-Healing
GLP-1 medications are everywhere right now — and so is the noise around them. One side calls them a miracle. The other says they're wrecking your metabolism, your gut, and your muscle. Neither version holds up when you actually read the evidence. In this episode, we look at what these drugs are really doing inside the body. What happens when appetite is switched off for months at a time. Why losing weight and losing strength can happen simultaneously — and what the DXA data from the STEP 1 trial actually showed about lean mass. Why two-thirds of the weight tends to come back after...

Why Stress Puts Weight On — And What Actually Helps
The Science of Self-Healing
You're stressed, you're exhausted, and the weight is climbing anyway. Everyone has an explanation. Almost all of them are wrong. The version you've heard stops at "stress raises cortisol, cortisol adds weight." What's actually happening is stranger and far more useful to know. Chronic stress doesn't just raise cortisol — it scrambles the timing of it. It rewires which part of your brain is making decisions at six o'clock. It changes the hormones that tell you when you're full. And there's an enzyme in belly fat that manufactures its own cortisol supply, right there in the tissue. In this...

Catch It Early: A Practical Guide to Insulin Resistance
The Science of Self-Healing
Your blood sugar can look completely normal on paper while your metabolism is quietly unraveling underneath. Insulin resistance often develops a decade or more before a diabetes diagnosis — and by the time it shows up on standard labs, the damage has already been building for years. In this episode, we break down what's actually happening inside the body as cells stop responding to insulin, why this single shift is linked to heart disease, fatty liver, PCOS, cognitive decline, and more, and the early warning signs most people miss — from afternoon energy crashes to stubborn belly fat to...

Alpha-Gal Syndrome: When a Bug Bite Turns You Allergic to Meat
The Science of Self-Healing
You've eaten burgers, steak, and bacon your whole life without a second thought. Then one tick bite changes everything. Alpha-gal syndrome is unlike any allergy most people have heard of — it doesn't come from a protein, it doesn't show up right away, and it can turn a lifelong meat-eater into someone who can't touch a hamburger without ending up in the ER hours later. In this episode, we break down how a single tick bite rewires the immune system, why symptoms hit three to eight hours after eating (long after most people have stopped suspecting their lunch), and what's actually happening...

Turning Autoimmune Disease Around
The Science of Self-Healing
50 million Americans live with an autoimmune disease. Nearly 80% of them are women. If that's you, you already know the fatigue that doesn't lift, the flares that show up with no warning, the feeling that your own immune system has somehow become the enemy. You've probably been searching for real answers for a while now. This episode asks a different question than the one you've been asked a hundred times. Not "how do we suppress this?" But "why did the body lose its balance in the first place?" In this episode, we get into: Why women are hit so much harder by autoimmune disease than men The...

The Cellular Cost of Ultra-Processed Foods
The Science of Self-Healing
You already know that ultra-processed foods aren't good for you. But do you know what they're actually doing inside your cells? In this episode of The Science of Self-Healing, we take a deep look at one of the most consequential — and overlooked — consequences of the modern diet: mitochondrial dysfunction. Your mitochondria do far more than produce energy. They regulate inflammation, support detoxification, balance hormones, and govern the body's ability to heal itself. And ultra-processed foods are disrupting all of it. From blood sugar instability and oxidative stress to gut microbiome...

Rosemary has been associated with remembrance since antiquity, and centuries later, herbalists were describing it as an herb that could strengthen memory and the senses. Today, modern researchers are uncovering intriguing biological reasons that this enduring connection may be more than symbolic.
In this episode of The Science of Self-Healing, Dr. James Odell explores how rosemary and its active compounds may influence memory, attention, alertness, brain energy, inflammation, oxidative stress, and the neurotransmitter acetylcholine. You’ll discover what researchers have learned from studies using rosemary aroma, rosemary water, and dried rosemary, why the compound 1,8-cineole is particularly intriguing, and how simply smelling rosemary may produce measurable effects in the body and brain.
Dr. Odell also looks at rosemary and the aging brain, practical ways to use this familiar herb, and why supporting memory involves much more than targeting a single pathway.
