Melissa Urban — founder of Whole 30 and author of The Whole30 (updated 2024) and The Book of Boundaries — sits down with Michael Easter for one of the most honest conversations on this feed yet. Two sober people (Michael 10+ years, Melissa 24+ years) unpack the parallels between drug addiction and food behavior, why the first time Melissa went to rehab didn't stick, and the single question that rewired every habit in her life: "What would a healthy person with healthy habits do?"

They dig into the science of elimination diets, the 17 years of data behind Whole 30, why Melissa publicly reversed her position on seed oils in 2024, how food becomes the fastest socially acceptable distraction from our feelings, and why you can white-knuckle any elimination program and end up exactly where you started. Plus: integrity over followers, mountains as church, and why "does this feel gross?" is the best business rubric Melissa's ever used.

The 130th Boston Marathon is this Monday. To mark the occasion, Michael sits down with Brady Holmer — a science writer, runner, and 2:24 Boston finisher — to go deep on what the race actually feels like, why super shoes might be saving you 5-8 minutes, how to fuel a marathon without your gut exploding, and whether anyone can qualify for Boston.

Then Dr. Mike Roussell, a PhD nutritionist from Penn State who works with NBA players and busy execs, breaks down the ultraprocessed food debate that's tearing through the nutrition world. Are ultraprocessed foods actually evil? Or are they sometimes the healthiest option? He walks through a mind-blowing ultraprocessed food study, why fiber is the most underrated nutrient, and a practical framework for using UPF without letting it wreck your diet. Plus his surprisingly nuanced take on GLP-1 drugs.

After that, Michael heads to the Two Percent Kitchen with the most ridiculous endurance recipe you've ever seen.

In this episode of Two Percent, Michael sits down with backcountry bow hunter and filmmaker Donnie Vincent to unpack what months in remote wilderness teach you about stress, calm, and competence. Donnie was featured heavily in Michael’s bestselling book, The Comfort Crisis, and now he joins Michael for the first time on mic since the book’s release.

They talk about the ethics and emotional reality of hunting, why sourcing your own food changes your relationship with life, and how modern convenience hijacks the ancient “search” that once made humans thrive. Donnie shares stories from Alaska—about storms, solitude, and the kind of discomfort that forces growth.

The two discuss the importance of building resilience when nothing's certain, staying present in wild places, and how you can get the same benefits of a hunt without ever picking up a bow – all it takes is choosing experiences that are hard and honest.

Walking shaped humans into who we are—and it’s one of the simplest ways to improve health, mood, and longevity right now. In this episode of Two Percent, Michael sits down with evolutionary geneticist Dr. Melissa Ilardo and writer Foster Kamer to explore what endurance science says about how far humans can actually go, why the brain often quits before the body, and how small daily choices compound into massive long-term outcomes.

We cover the real research behind step counts (including why the 10,000 number is a myth), the minimum effective dose that meaningfully improves health, and how to make walking effortless by stacking it into things you already do. Plus: persistence hunting, sleep differences that change performance, and what ultra-endurance reveals about mindset.
