The best part of Longevity Fest in Las Vegas is never just the lectures. It’s the conversations with colleagues whose work has shaped how I practice medicine and their books are the ones I recommend to my patients again and again.

If you are a woman who wants to understand her own body, start here:

📚 Younger You by Dr. Kara Fitzgerald
Dr. Kara’s research showed that biological age can be reduced through food and lifestyle. This is epigenetics made practical.
📚 Women, Food and Hormones by Dr. Sara Szal Gottfried
Dr. Sara understands that women are not small men. If nutrition advice has never quite worked for you, your hormones are probably the reason.
📚 Menopause: 50 Things You Need to Know by Dr. Felice Gersh
Dr. Gersh is one of the strongest voices in women’s hormonal health. This is the book I wish every woman read before perimenopause, not after.
📚 The Peptide Handbook by Jim LaValle
A clear guide to one of the most exciting areas in longevity medicine, and a good starting point if you keep hearing about peptides and want the facts.
📚 You Can Fix Your Brain by Dr. Tom O’Bryan
Brain fog, poor sleep and memory lapses are not “just stress”. Dr. Tom explains what is really driving them and what you can do in one hour a week.

Save this post for your next bookshop visit.

I will be back at Longevity Fest this December, in the same rooms with these brilliant minds. What would you like me to ask them? Leave your question in the comments and I will bring the answers home with me. 👇

“This is a key concept when you want to be healthier.” – Dr. Tom O’Bryan 👀

Could the health of your gut be connected to your heart?

In this clip, Dr. O’Bryan explains why, in his view, the gut may be a starting point for chronic inflammation.

Chronic inflammation is linked to many of today’s leading causes of death, including heart disease and type 2 diabetes. Researchers are still uncovering how much of the story begins in the gut.

It’s one of the many perspectives explored in our new original docuseries, HEARTproof. ❤️

🎬 Watch HEARTproof FREE – link in bio.

Featuring Dr. Tom O’Bryan, one of 36 leading experts in cardiovascular and metabolic health exploring what the latest science and clinical experience can teach us about cardiovascular risk, prevention and healthy longevity.

Your gut bacteria aren’t just helping you digest food. They’re constantly communicating with the rest of your body…your brain in particular!

It’s the microbiota from your gut that turns on the assembly lines to make the neurotransmitters for how you think. Are you anxious? Are you calm? Are you excited by life? Are you depressed? All of those emotions are affected by the health of our gut bacteria!

In this clip, Dr. Tom O’Bryan explains how compounds produced by the gut microbiome enter the bloodstream and act as messengers throughout the body, influencing gene expression and the production of neurotransmitters involved in how we think and feel.

The health and diversity of our microbiome have effects that reach far beyond our gut.

🎧 Listen to Episode 327 of Dr. Lo Radio, “Inflammation, Infertility & the Hidden Drivers of Chronic Disease,” with @thedrtomobryan wherever you listen to your podcasts.

This fascinating conversation dives into the microbiome, environmental toxins, chronic illness, fertility, testing, healthy aging, and why looking “upstream” may help uncover what’s driving your health issues. #guthealth #naturopathicmedicine #inflammation

Lifelong learner. Always. ❤️

What an incredible day at the A4M Microbiome Keynote Symposium here in Nashville.

Today’s presentations reinforced something I’ve believed and taught for years:

We cannot look at hormones in isolation.

The gut, brain, immune system, nervous system, mitochondria and endocrine system are in constant communication - and understanding those connections can completely change the way we think about health.

We explored everything from endotoxins and cardiometabolic dysfunction to the gut-thyroid axis, sympathetic and mitochondrial dysfunction, and the fascinating relationship between gut and immune signals, hormonal changes, cognition and the midlife female brain.

I especially loved the discussion surrounding the microbiome and women’s hormonal health - including PCOS, perimenopause and menopause.

And the timing couldn’t be better. ✨

I’m bringing some of these clinical pearls into our next Wellness Wednesday: Hormones & Harmony, where we’ll talk about why hormone balance is about so much more than estrogen, progesterone or testosterone - and why the health of the gut, brain, stress response and whole body matters.

One of the highlights of the day was also this wonderfully serendipitous moment with friend Dr. Tom O’Bryan, a true trailblazer in gluten sensitivity, autoimmunity and functional medicine education. I have tremendous respect for his work and even more appreciation for the exceptional human being behind it.

After more than 25 years in medicine, I still get genuinely excited about learning. There is always another connection to uncover, another question to ask and another piece of information that may help us better understand the person in front of us.

I can’t wait to share more at Hormones in Harmony.

Every year, some of the most influential voices in health gather in one room, and this weekend it happens for the very last time.

The Mindshare Summit is where the doctors, bestselling authors, and podcast hosts you trust come together to learn how to reach you. Books get born there. Podcasts find their guests. Ideas that change how women are cared for often start over a lunch table in San Diego.

For 15 years it's been one of the most respected gatherings in our world, and I'm so honored to be part of its final chapter on the Business of Menopause panel, talking about what you've been asking for and what better care really looks like.

Last weekend at the Vitality Experience in Dallas, I got to spend two days in a room full of you, and I'm carrying every one of those conversations with me to San Diego.

To my dear friends in these photos. @jj.virgin, thank you for founding this community and for standing beside me in Dallas. @dave.asprey, @izabellawentzpharmd, @tonyyounmd, @shawnmodel, @thedrtomobryan and @deannaminich, I can't wait to hug you one last time at Mindshare.

If you've been waiting for a sign to finally start putting yourself first, this is it. Comment MINDSHARE and I'll send your next first step straight to your DMs.

Bacteria from your gut is leaking into your blood right now. Here’s how it happens.

@drjoshaxe, @thedrtomobryan and @drmarkhyman break it down in Transcendence.

Comment FILM and I’ll send you the entire series, free.

There’s a barrier between your intestines and your bloodstream. Your gut lining. It’s one cell thick.

When it’s inflamed, larger holes open up. Undigested food particles, toxins and bacteria pass straight into the blood. Your immune system sees something foreign and attacks. Exactly as it should.

The problem is when that response doesn’t stand down.

Research on gluten and intestinal permeability found something most people have never been told. When humans eat wheat — not just people with celiac — the gut lining becomes more permeable.

Here’s why that usually doesn’t matter. Your gut lining rebuilds itself every three to seven days. Like a snake shedding skin. It tears, it heals. Tears, heals. Day after week after month after year.

Until one day you don’t heal anymore.

Once that immune response is running, it starts hitting your own tissue. The joints, and it looks like rheumatoid arthritis. The thyroid, Hashimoto’s. The colon, Crohn’s. The muscles, fibromyalgia.

Then Mark adds the part I keep thinking about.

Fifty years ago researchers stored blood samples from 10,000 people and tested them for celiac. They compared those to 10,000 people today.

A 400% increase.

Same genes. Four times the disease. It isn’t a fad. Something changed in the food, not in us.

None of this is a reason to stop what your doctor has you on. It’s a reason to ask a different question.

So tell me — has anyone ever looked at your gut? 👇

Josh, Tom and Mark are three of 35 people I sat down with for Transcendence, alongside @drlibby, @brucelipton and @thefoodbabe. A series about healing, transformation, and reclaiming sovereignty over your body, your mind and your life.

Arthritis, Hashimoto’s and celiac are all autoimmune diseases. They get treated as three separate conditions by three separate specialists. There’s growing evidence they share a starting point — and it’s not where anyone’s looking.

@thedrtomobryan and @drjoshaxe break it down in Transcendence.

Comment FILM and I’ll send you the entire series, free.

Hippocrates said it 2,400 years ago: all disease begins in the gut. We’re only now catching up to what he meant.

Your gut lining is one cell thick. That’s the entire barrier between what you ate and your bloodstream. It rebuilds itself every few days, which is remarkable — as long as nothing keeps damaging it faster than it can repair.

When that lining is compromised, things cross the barrier that were never meant to. Undigested food particles. Bacteria. Straight into the blood.

Your immune system does exactly what it’s supposed to do. It sees something foreign in the bloodstream and attacks.

The problem is what it attacks next.

Once that immune response is switched on and stays on, it starts hitting your own tissue. The joints, and it looks like rheumatoid arthritis. The thyroid, and it looks like Hashimoto’s. The gut itself, and it looks like celiac.

Three diagnoses. Three specialists. One immune system responding to one breach.

That’s why Dr Axe says you can clean up the diet and still not heal. If the barrier is still open, the immune response never stands down.

To be clear: none of this is a reason to stop what your doctor has you on. It’s a reason to ask a different question.

So tell me — if you’re dealing with one of these, has anyone ever looked at your gut? 👇

Wait, what? Eating more fruits & veggies linked to worse pregnancy outcomes?

@thedrtomobryan references a @harvardmed study points to pesticides, not produce itself.

Mind blown.

She was 38 years old chronologically, but biologically, her results showed 75.5 ⌛️🔥

She thought she was eating clean 🥗
Doing everything right📋

But underneath the surface, her body was overwhelmed by inflammation, oxidative stress and poor recovery.❤️‍🩹

This Saturday at 10 a.m., I’m joining @thedrtomobryan to break down a real life complete case report and show how precision testing can reveal what symptoms alone cannot.

If you’re a Practitioner or simply curious about your own health, comment INTERESTED below and I’ll send you the details.
