DR. GUNDRY PODCAST: GUT HEALTH, WEIGHT LOSS, AND NUTRITION

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" dose you've been warned about is a myth that's kept millions of people needlessly deficient
Why this one hormone might be the closest thing we have to a longevity switch.

Plus, learn the exact number I push my own patients' levels to, and why your doctor's idea of "normal" is probably way too low.

Think sardines are just an old-fashioned pantry staple? Think again.
In this episode, I'm breaking down why these tiny fish may be one of the most powerful foods you can add to your diet. Packed with omega-3s, high-quality protein, minerals, and nutrients that support everything from your brain to your heart and gut, sardines deliver remarkable health benefits in one small package.
I'll explain what makes sardines different from larger fish, why they're one of the safest seafood choices, how to choose the best canned varieties, and the biggest mistakes people make when buying them. Plus, I'll share my favorite ways to enjoy sardines—even if you've never been a fan.
If you're looking for a simple, affordable food that can have an outsized impact on your health and longevity, you won't want to miss this episode.

Have you asked ChatGPT or Claude a health question before?
AI is already changing how patients research symptoms, read labs, and make health decisions — and that could be one of the most empowering shifts in medicine, or a potential disaster. My guest today knows exactly where that line is.
Dr. Vivienne Ming is a theoretical neuroscientist who's spent 30years building AI to expand human potential, founding more than a dozen companies along the way. She has built one of the first AI systems ever designed to help manage a disease, and she shares it all in her new book, Robot-Proof: When Machines Have All the Answers, Build Better People.
On this episode, we get into where AI genuinely helps your health, where it quietly diminishes your own power of intellect and reason, and why the smartest "mind" in any room isn't a genius or a supercomputer.
On this episode, you’ll learn:
Why doctors and AI make "complementary" errors—and how combining them beats either one alone (01:31)
How outsourcing your thinking to AI over a lifetime could raise your risk of THESE health issues (06:54)
A fascinating experiment that reveals how you can build richer, denser brain connections through this (10:03)
Why your brain does a nightly cleanup during sleep (13:25)
The "nemesis prompt" trick for using AI to challenge you instead of letting it do the thinking for you (15:24)
What the "Jiffy Lube colonoscopy" problem is, and which doctors suffer from it the most (18:13)
The hidden bias problem in medical AI—and why it may perform worse for underrepresented populations (27:42)
The real reason AI hallucinations can never be fully eliminated, and what that means for how much you should trust it (30:00)
A simple technique for using AI to build real understanding of any health condition (40:15)
Practical guardrails for deciding how much to trust an AI answer before you bring it to your doctor (45:02)

Why doesn't counting calories work for weight loss?
Can you lose weight with exercise alone?
Is weight gain really about willpower and discipline?
What role do gut bacteria play in weight loss?
Why do most diets fail in the long run?
How does gut health affect your metabolism and cravings?
