Beef tallow is making a huge comeback. Seed oils are under fire. And suddenly, everyone seems to have an opinion about what you should be cooking with.

But what does the science actually say?

In this episode, I'm breaking down one of the biggest nutrition debates today: beef tallow vs. lard vs. olive oil. I'll explain how decades of government dietary advice changed the way Americans cook, why animal fats disappeared from our kitchens, and whether they deserve a place back on your plate.

You'll also discover the surprising truth about olive oil that most people get wrong, my thoughts on the butter-in-coffee trend, and the cooking fats I actually recommend after decades as a heart surgeon and nutrition researcher.

If you've ever wondered which fats are helping your health—and which ones are quietly working against it—this episode is for you.

You've got a bottle of extra virgin olive oil sitting in your kitchen right now. I'd bet money on it.

But I'd also bet you're only using it for one thing, cooking. Maybe the occasional salad dressing if you're feeling fancy. What if I told you that's like buying a Swiss Army knife and only ever using it to open envelopes?

In this episode, I'm sharing eight science-backed ways olive oil can transform your health, and none of them involve a salad. We're talking about your brain, your joints, your gut, your skin, your ears, and even your snoring. Yes, really.

This golden liquid has been used medicinally for thousands of years, and modern research is finally catching up to what the ancients already knew. By the end of this episode, you're going to look at that bottle on your counter completely differently.

On this episode, you’ll learn:

• How you can transform your oral health by doing THIS surprising hack (01:44)
• Why snoring can be your body signaling a much deeper issue (03:03)
• The skin secret Cleopatra and Sophia Loren both swore by (04:20)
• The incredible study that resulted in MRI-confirmed brain changes, improved memory, attention span, and executive function (05:34)
• The one mistake most people are making when it comes to their ear health (07:51)
• Which household item outperformed a prescription pain gel (08:45)
• The virtually free morning ritual that can kickstart digestion and support a healthy bowel rhythm (09:59)
• Why what you see on your scalp is really a sign of systemic inflammation (11:06)
• Three things to look for on an olive oil label before you buy (12:21)

Apple cider vinegar is everywhere right now. From celebrity endorsements to social media trends, it's become one of the most talked-about wellness staples. But does it actually live up to the hype?

In this episode, I break down what apple cider vinegar really is, the science behind its potential benefits for weight loss, blood sugar, and hunger, and what can happen when you take it every day for 30 days. I'll also share why it may do much more than support your metabolism—including benefits for your gut and overall health.

Plus, I'll explain how to choose the right apple cider vinegar, what to avoid, and the simple mistakes that could keep you from getting its full benefits.

Every time you pop an antibiotic, you think you're winning the battle, but what if you're quietly losing the war? Sure, antibiotics can be lifesaving. But in our modern times, antibiotics are often prescribed for everything… even when they make no difference at all.

Most people never stop to ask: Do I really need this antibiotic? Or better yet: What studies show this will actually help my condition?

And ultimately, we never stop to ask what happens after the infection clears. The truth is, that the prescription your doctor handed you may have saved you from one problem while creating a much bigger one you won't see coming for months — or even years.

In this episode, I'm pulling back the curtain on what antibiotics are really doing to your gut, why the damage goes far deeper than you've been told, and what you can actually do about it if you've ever taken one, or a hundred.

On this episode, you’ll learn:

• Why you should think twice before filling that next antibiotic prescription (00:06)
• What Stanford researchers say about getting your gut bacteria back after a course of antibiotics (03:47)
• What your gut bacteria have to do with your immune system (03:55)
• Why conditions like eczema, psoriasis, and mystery rashes may actually be your gut waving a red flag (05:15)
• Exactly what to ask your doctor before you accept a broad-spectrum antibiotic prescription (08:00)
• The top tips for rebuilding your gut after antibiotics (it isn't as simple as taking a probiotic!) (12:10)
• All about the shocking amount of antibiotics found in meat (14:53)
• The real reason your pet may be suffering from itchy skin (17:53)

NAD is everywhere right now: supplements, injections, podcast topics, longevity clinics. And I'll be honest, when something gets this trendy, I get skeptical. But NAD is different. This is actually something I've been watching closely for nearly 25 years, and the science has finally caught up.

Here's what most people don't realize: the exhaustion, the brain fog, the slower recovery you've been chalking up to "just getting older"? That's often your NAD levels in freefall, and it's happening earlier than you think.

On this episode, I'm breaking down what NAD actually does inside your cells, why most supplements on the market are quietly failing you, and what I looked for when I finally designed my own formula — Gundry MD Elevate NAD+. I spent years waiting to make one until I could develop an NAD supplement that delivered you real results.

On this episode, you’ll learn:

• What the "second baseman" is, and why it is the most important player in your cellular health (3:09)
• All about the French Paradox and its connection to NAD research (4:32)
• What fasting and strength training have in common that no one talks about (6:15)
• The dirty secret about most NMN supplements on the market (7:35)
• 3 reasons your NAD gets depleted (and what a well-designed formula like Gundry MD Elevate NAD+ actually does about it) (15:25)
• The checklist I use to evaluate any NAD supplement (17:41)
• What age should you actually start thinking about NAD support (12:21)
• What real NAD support looks like in practice (hear my personal story) (10:57)

You can't scroll through your feed for five seconds without seeing someone talking about Ozempic, Wegovy, or the newest GLP-1 drug.

But here's what nobody is telling you: your body was already designed to make its own version of this appetite-suppressing hormone.

However, most of us have stopped feeding the good bacteria responsible for producing it.

In this episode, I'm breaking down the gut-centric theory of hunger, a fascinating concept that completely changed the way I think about appetite, cravings, and weight management.

Plus, I'll share what happened when I personally experimented with a specific category of food for my upcoming book and experienced something I can only describe as... injecting GLP-1. Without the injection.

On this episode, you’ll learn:

• The science behind what GLP-1 actually is (1:40)
• The real reason you feel like you can’t stop eating (and what you can do to stop it) (4:33)
• All about the jaw-dropping Chinese study where volunteers minimized their hunger (9:03)
• Exactly which foods crank up your body's natural GLP-1 production (11:29)
• The one food category I added to my own diet that had me leaving half my meal on the plate (13:43)

I trained at one of the world's most prestigious medical institutions and spent years following conventional medical wisdom. But after watching the same advice fail patient after patient, I started questioning everything.

In this episode, I reveal why I believe some of medicine's most accepted ideas — from cholesterol to calories-in, calories-out — are deeply flawed. We'll explore the gut microbiome revolution, the outdated thinking still shaping healthcare today, and the discoveries that completely changed the way I approach weight loss, heart disease, inflammation, and chronic illness.

Did you know which Medicare plan is right for you? Well, I've seen it firsthand when patients don't know their options, and it's devastating...

That's why I brought Ari Parker on the show. He's a Stanford-trained attorney, co-founder of Chapter, and one of the few people in this country who is genuinely fighting for Medicare recipients — not selling them something.

What we talk about in this episode could save you thousands of dollars, protect your access to the doctors you trust, and give you something most people on Medicare don't have: real options.

On this episode, you’ll learn:

• Why signing up for Medicare even two years late can cost you a lifetime penalty (03:00)
• How Medicare Advantage plans use free dental, vision, and hearing benefits as bait 14:09)
• The two types of Medicare most people don't realize they have to choose between, and why the option that's never advertised on TV may actually be the better fit for you (06:48)
• What the "Three Ps" are — and how they can match you to a plan that actually fits your life, not a salesperson's quota (16:58)
• Exactly what happens when your insurance company denies a test your doctor ordered — and how to advocate for yourself (28:43)
• Top tips you should know about your Medicare plan before important windows close (19:40)
• The real reason Diet Coke makes you overeat (I was once a Diet Coke addict!) (33:55)

This episode was sponsored by Chapter, but Dr. Gundry's experiences and opinions are his own.
