The B.rad Podcast

In this episode, I go through my deep and fascinating experience with the Stride health optimization program.

You'll hear me walk through the six detailed reports from my DNA and microbiome testing—starting with the methylation report, where I had impaired efficiency in the folate cycle, methionine cycle, and BH4 cycle, and finally got a normal score in the transsulfuration pathway. I talk about the role of key nutrients like...

In this episode, I take a hard look at the glorification of obsessive training habits in elite sport, using Michael Phelps’ famous claims—like eating 10,000 calories a day and not missing a single day of training for six straight years—as a springboard for discussion.

You’ll learn how research from top performance labs has shown that these types of extreme regimens aren’t just unsustainable, but unnec...

During this episode, I talk to former firefighter and chief breath officer of Jaspr, Wes Greenwood, about the unseen world of air quality and what’s really in the air we breathe—both indoors and out.

You’ll learn how air filters like the Jasper actually catch pollution, what particulate matter is, how cooking (even clean, grass-fed steak) produces airborne compounds, and how most kitchen range hoods are either und...

Please welcome Sasha Graham, the host of the Sports Will Save Us All podcast!

What a great name for a show, and I had a great time being a guest on it—we had a wide ranging conversation and really hit it off as she hit me with some surprise questions, trying to put me on the spot…it was wonderful that I said, you know what—how about I bring you onto the B.rad podcast? We turned the tables and while I didn&rs...

I welcome bestselling author Ben Azadi to the show on the occasion of the release of his new book called Metabolic Freedom: A 30-Day Guide to Restore Your Metabolism, Heal Hormones & Burn Fat.

Of course, we get into all the important talking points about the ketogenic diet, intermittent fasting, how to lose body fat safely and sensibly, but this show is also going to be way more than you bargained for, because we got into a ni...

In this episode, I share my full DEXA scan results, including a visceral fat score of 0.38 pounds, which I’m determined to drop to “0.0 fricking zero” through sprinting—shown in research to preferentially burn visceral fat.

My body fat is 21 pounds (12.5%), and I break down the fat and lean mass distribution throughout my body, including minor asymmetries. I was advised to gain 2–3 pounds of muscle for...

In this episode, I sit down with my go-to expert for all things sports performance and injury recovery—Dr. Jonathan Sanburg, a highly respected physical therapist who’s changing the game when it comes to getting people back to peak performance.

We dive into what’s truly cutting-edge in the industry right now: treating injuries from a fitness and athletic performance lens, instead of the o...

This show was inspired by a very thoughtful question from a college-aged listener named Justin who wanted to know what my current training regimen is like, and if I believe zone two training is really necessary, if VO two max workouts are really necessary, and if I think he should just take up a sprinting regimen (since the sprinters seem to look the best and be the healthiest)?

Thanks, Justin, for teeing me up—I thought his ...

In this episode, I break down the pros and cons of the popular practice of consuming energy bars as a supposedly nutritious snack on the go.

The inspiration for this show was an exciting spicy battle between health experts Dr. Layne Norton and Gary Brecka on Instagram, where they debated the merits of the new David High Protein bar. I talk about the ingredients in these bars, the processing methods, and the overall sketchy nature o...

Welcome to class!

Welcome to another show about the big toe (hopefully you heard the first presentation, What’s the Big Deal About the Big Toe?) because in this episode, we’re taking it further.

You will learn why your big toe is crucial for efficient movement, and how its functionality influences everything from your running stride to balance. I reveal how wearing tight, restrictive shoes can hinder your big toe’s ability to funct...

In this episode, you will learn about the critical role the big toe plays in human movement and athletic performance.

I reveal the truth about how shoes can weaken and restrict your big toe, leading to imbalances and a higher risk of injury, especially as we age. You'll hear how the big toe impacts everything from balance to the activation of your glutes, which are essential for powerful movement.

I’ll also guide you through ...

It’s time for a rebroadcast of a wonderful interview with my old friend, Dr. Casey Means, where she talked about the launch of her book, Good Energy.

It has been a year since we talked on the eve of her book launch, which was just about to go number one and become a New York Times bestseller, and in other news, Dr. Casey has just been appointed to become the Surgeon General of the United States of America. Amazing news, a bit...

In this show, I share more thoughts on my new, recent longevity mantra: perform, recover, perform, recover.

These thoughts were inspired by an interaction I had with my friend Michael Kummer—host of The Primal Shift podcast—who recently wrote a newsletter article about the longevity practices of the increasingly prominent biohacker Bryan Johnson.

While I appreciate a lot of things that Bryan does in service to the ...

I'm pleased to welcome Henry Abbott, the author of a new book called Ballistic: The New Science of Injury Free Athletic Performance!

What an interesting conversation we had, and we went on a wide ranging journey through several topics of interest in modern big time sports. Henry has a longtime sports background–he is an award-winning journalist who led ESPN’s 60 person NBA digital and print team. So he is a longtime NBA...

Shawn is one of the world’s leading health experts as the bestselling author of Sleep Smarter and host of the #1 rated Model Health Show.

The first part of the discussion is about foot functionality. Shawn mentions the emerging research on how minimalist shoes can address the cause of foot dysfunction, “nourishing and rehabilitating our feet.” Then describes the awakening he has experienced using Peluva five-toe ...

In this episode, I’m diving into some fascinating research and sharing my own opinions for a fun, insightful show about longevity and living to 100 years old. It is amazing to think there are 722,000 centenarians alive today, but only 219 people who’ve made it to 110. I think genes affect your potential to live to 110, but most of us should form the empowering belief that we can sail to 100, if we just get out of our ow...

Enjoy this second show with Alex, where we left the mic on after our interview emphasizing his book, The Explorer’s Gene, and started talking about Mark Sisson and my new book, Born To Walk.

We planned to have a “friendly debate” about the book’s premise that running is a bad idea for most people. Alex, as a longtime runner, had a much different basic notion—that running is a rich and meaningful form ...

Please enjoy my B.rad podcast conversation with Alex Hutchinson, the world’s leading science-sport journalist and NYT best-selling author of Endure.

The occasion is the release of his long-awaited next book, titled The Explorer’s Gene, and in this much-anticipated follow-up to Endure, he refutes the myth that, in our fully mapped digital world, the age of exploration is dead. Instead, the itch to discover new thing...
