Poop. Did you know that what lands in your toilet every day is the most honest report card your body will ever hand you? In episode 429, I’ll answer all the poop, constipation, and gut health questions you’ve always wanted to ask, and we’re going to do it rapid-fire because you sent in so many. Here’s what most people never realize: a large proportion of your poop is living and dead bacteria, not the food you ate. That means its size, shape, color, and smell are telling you how well you’re fee...

Ready to spice up your life? I’ve got seven spices almost nobody in this country has heard of—even though they’ve been used in kitchens and medicine cabinets around the world for thousands of years. From Grains of Paradise (my daily swap for black pepper) to black seed, sumac, and a smoky cardamom that protects your liver, the research is finally catching up to why these ancient ingredients work. As Hippocrates said, let food be thy medicine — and now we know why. In this episode, you’ll learn...

What IS fatty liver? Why nearly every patient I test has some degree of fatty liver, and how to reverse it — because this may be the most common condition almost nobody knows they have. On this episode, you’ll learn: Why your liver can be in trouble for years with zero symptoms (00:00) How foie gras is really made — and why your liver may be next (03:13) The great-ape “thrifty gene” quietly turning fruit into liver fat (05:50) The 4 numbers that reveal a fatty liver before it’s too late (14...

Creatine has more to do with your brain than your biceps. It helps your cells recycle ATP, the energy your brain burns through faster than almost any tissue you've got. So it isn't really about building bigger muscles at all. It's about energy, focus, and staying sharp at any age. In my latest episode, I break down what creatine actually is, how much to take, and the 3 things I check on every label before I buy, because this is one of the most contamination-prone supplements out there. On this...

Asthma. What if the wheezing, the tight chest, the inhaler you reach for every spring isn’t really a lung problem at all? In this episode, I’ll explain why asthma has skyrocketed since the 1960s and what you can do to fix it. Questions I’ll answer: Is asthma really a lung disease… or an overreactive immune system firing from somewhere else entirely? Could our obsession with “clean”, like sterile homes, sterile hands, sterile food, be the culprit? Why did almost no one have these problems a fe...

In this episode, I break down the real reasons we feel pain in the first place, why the most popular over-the-counter painkillers are quietly making your pain worse the longer you take them, and the smarter, natural tools I reach for with my own patients. From ice versus heat, to Epsom salt baths, to the surprising gut connection behind migraines, I’ll show you how to work with your body’s signals instead of blasting through them. Because when you understand that pain is information, you stop a...

What if a 30-second morning habit could lower your blood pressure — no pill, no diet overhaul? In this episode, I'll reveal an ancient trick modern science just confirmed, and why the “minty fresh” mouthwash in your cabinet may be quietly driving your blood pressure up. Highlights: The nitric oxide connection — the Nobel Prize-winning molecule that dilates your blood vessels, and why it fades with age Why mouthwash backfires — killing “99% of bacteria” wipes out the good bugs that lower your ...

I'll bet you've never heard the word sarcopenia — but I promise you, it's happening to you right now. Starting around age 30, you begin quietly losing muscle mass, and here's the scary part: most of my patients never feel it happening until it's robbed them of the last 20 good years of their life. So today, I want to let you in on something I've learned after seeing patients six days a week for over 25 years: this kind of muscle loss is NOT a normal part of aging. I can prevent it, and so can yo...

Are we focusing on the wrong thing when it comes to protein and healthy aging? In this episode, I break down fascinating new research from my friend Dr. Valter Longo that could change the way you think about protein, muscle, and longevity. The key may not be how many grams of protein you eat, but how much of one specific amino acid, methionine, you're getting. I explain what the study found, why too much or too little methionine may matter, and how mTOR, IGF-1, GLP-1, and gut health fit into t...

We've all been taught that if it's a vegetable, it belongs on your plate. In this episode, I walk you through five of the biggest offenders and what's actually happening in your gut when these foods show up on your plate. Plus, learn the simple prep tricks that can make several of these foods safe again. On this episode, you’ll learn: Why Europeans called the tomato the "poison apple" — and the simple prep trick to make them safe again (01:19) The science behind lectins and how they damage y...

I explain why high-quality formulas can cost more than what you’d find on a drugstore shelf, and walk you through specific ways to lower what you pay—including a subscription option that can save you up to 60% on certain products, plus a free My Account option that gives you more control over your orders and access to member-only pricing. I also share a real example from my own patients about what can happen when you stop taking a formula that’s working—and why staying consistent can matter jus...

Most people think more cardio is better for you. Run more, burn more, live longer, right? Well, my guest today says that's backward. He's suffered from aching knees, a busted hip, and a he has a brand-new book to prove it. Mark Sisson is a New York Times bestselling author and the co-founder of the barefoot shoe company Peluva. He was one of the very first people I read when I left heart surgery to become a nutritionist, and today he's back with his latest book, Born to Walk: The Broken Promis...

Let's be clear: Dr. Gundry has NOTHING against the carnivore diet as an elimination diet. In fact, some of his patients practice it, and it does support their gut health because it removes all lectin-containing compounds in your diet. But there’s much more information you need to know if you plan on practicing this diet. That’s why in this episode he will be discussing the shocking truth about the carnivore diet you need to know.

What if I told you the "healthiest bread on earth" comes from a recipe that was originally supposed to be baked over human feces? It's true, and that recipe is straight out of the Bible. Right now, the internet is obsessed with the so-called Bible diet, also known as the Biblio diet, Promised Land diet, the Daniel diet, or simply biblical eating, but most of what's out there is cherry-picked scripture with zero context. So I decided to do it properly: chapter and verse, calling out what ancie...

Want to know what I actually do every day to stay healthy, energized, and youthful as I get older? In this episode, I’m giving you a look inside my personal daily routine and sharing the simple habits I rely on to support longevity and healthy aging. I’ll walk you through the way I eat, move, and structure my day, along with the small lifestyle choices I make consistently to help keep my body and brain performing at their best. And you don’t need an expensive anti-aging routine or hours at the ...

I've spent 25 years telling patients the same thing: I can show you the path, but you have to walk it. Nobody proves that better than my guest today. Jim Kwik was labeled "the boy with the broken brain" as a kid — migraines, learning disabilities, couldn't keep up in school. Today he's the guy Navy SEALs, Olympic athletes, and Fortune 500 CEOs call when they need to think sharper and perform better. His new book, Limitless Daily: 366 Keys to Train Your Brain, Master Your Mind & Win Every Day, ...

Traveling back in time is impossible. Giving your cells a fresh start is not. In this episode, I dig into stem cells: what wakes them up, why the wall of your gut matters so much, and the two very different ways cells die. One causes inflammation. The other, called autophagy, lets your body rebuild itself from the inside out. I break down how time-restricted eating, polyphenols, and mitochondrial uncoupling work together to build a genuinely new you every three months. Plus, a great question on ...

Everyone's chasing the wellness hack that'll finally crack the code on living longer: cold plunges, biological age tests, or extreme fasts. But my guest today just wrote an entire book making the opposite argument: most of that noise doesn't matter nearly as much as we think, and the real answer to a long, healthy life is a lot simpler than the wellness industry wants you to believe. Dr. Ezekiel "Zeke" Emanuel is a Harvard-trained oncologist, Vice Provost for Global Initiatives at the Universi...

Sugar isn't just a habit; it's one of the most addictive substances in our diet, and most of us don't even realize how much we're consuming. In this episode, I'm breaking down my simple, four-step method for kicking a sugar addiction for good, without feeling deprived. I'll show you exactly where sugar hides on food labels (hint: it's not where you think), teach you the quick math trick that reveals the real sugar content in any packaged food, and explain why "healthier" sugars like honey, agav...

Bad breath could be the earliest warning sign of something happening deep inside your body, and most people are trying to fix it with exactly the wrong tools. It's rarely just a hygiene issue. It can point to low stomach acid letting the wrong bacteria take over your gut, leaky gums mirroring leaky gut, or a dead tooth hiding an infection you'll never feel. On this episode, you'll learn my five tips (plus a bonus) for getting rid of bad breath for good, what your breath is really telling you a...

Want to keep your brain sharp as you age? Start with what’s on your plate. In this episode, I’m sharing 5 amazing foods your brain will love — and why adding them to your diet may help support memory, focus, and long-term brain health. Some of these foods may already be in your kitchen, while others might surprise you. Either way, your brain will thank you.

Big Pharma bet billions on one theory: clear the amyloid, cure Alzheimer's. A new Cochrane review of 20,000+ patients just proved them wrong — these drugs don't work, and they may be putting your brain at risk. So what's really driving this epidemic? My guest today, six-time New York Times bestselling author and board-certified neurologist Dr. David Perlmutter, says the answer lies in a set of cells most people have never even heard of — and he lays it all out in his new book, Brain Defenders....

Water is essential for life—but could drinking more of it actually be working against you? In this episode, I’m tackling one of the biggest hydration myths out there: that everyone needs eight glasses of water a day. I’ll explain why your individual water needs may be very different, how drinking too much water can throw off your electrolyte balance, and why overhydration may even affect how efficiently your heart works. Plus, I’ll share the signs you may be overdoing it, what really counts to...

I once had a patient tell me, "You don't know much about vitamin D, do you?" He had a point, not because I hadn't studied it, but because so much of what we're taught about vitamin D simply hasn't caught up to the research. My patient’s question led me down a path of research that changed how I treat every patient who walks through my door. In this episode, I break down Why vitamin D isn't a vitamin at all but a hormone quietly running the show for your gut and immune system Why the "toxic"...
