691. How Microplastics Are Getting in Your Brain & Your Sperm w/ David Roberts

The Life Stylist

Show Notes

We’ve been ingesting microplastics, and no one is talking about it.

That result is what first got David Roberts, co-founder and managing partner of Mara Labs, interested in microplastics.

Most broccoli supplements don't contain what their labels claim. One doctor even teared up in front of him at a conference when they realized what they'd been recommending for years. The GLP-1 side effect story is even uglier than the headlines suggest, with nearly 4,000 lawsuits and up to 40% of lost weight coming from muscle.

Where do microplastics accumulate? Why is your dryer lint a warning sign? What do fenugreek and beta-glucan do in the gut? And what’s the two-step pathway that mobilizes plastic out of your cells and into your stool?

If you've ever wondered whether the supplements you're taking are actually reaching your cells, this one will change how you shop.

In this Lonesome Conversation, Kyle and I explore a hunger most of us don’t know we have — the deep deficit of physical touch in Western culture, where contact gets siloed off into family or romance with nothing in between. He explains how we’re biologically wired for touch as co-regulation, how we convince ourselves we’ve “outgrown” the need, and why you can’t feel the lack until something finally fills it. A reframe of loneliness as, in part, a body starved of the care it was designed to receive. About Kyle Kyle Coursey is the creator of THE RESET, a one-of-a-kind experience. He works with high-performing and high-functioning individuals, founders, and executives who have done the work but still feel something is off. His work focuses on identifying and resolving the underlying distortions in the human system, across nervous system, physiology, psychology, and relational patterns, so clients can return to clarity, performance, and internal stability. Through his immersive RESET sessions, he compresses years of work into a single, focused experience designed to restore coherence and unlock what’s been inaccessible through conventional approaches. Lonesome Conversations Limited Series Lonesome Conversations is a special series from The Life Stylist, built around my new book, A Horse Named Lonesome (out November 17, 2026). Loneliness is something almost everyone goes through, and almost nobody talks about honestly. So I sat down with psychologists, philosophers, trauma therapists, teachers, and friends to find the truth about loneliness, and how we heal from it. Each episode is its own conversation, but together they walk the same ground the book maps out. (Pre-order your copy at ahorsenamedlonesome.com) You'll find new episodes alongside our regular show over the coming months.

Thirty minutes after the biggest relief of his life, Dylan Gemelli found out his apartment was being ransacked, with half a kilo of cocaine in the safe.

Oct 18, 2026

I join my brother Kyle Kingsbury for a raw conversation about the life experiences behind my new book, A Horse Named Lonesome. We trace my journey from childhood abuse and addiction to recovery and spiritual awakening, exploring how shame, trauma, and the illusion of separation can keep us disconnected from ourselves and others. We also get into forgiveness, ego death, 5-MeO-DMT, and the hard-earned lessons that ultimately inspired me to share this book with the world.

In this Lonesome Conversation, Dr. Lipton and I explore his striking claim that loneliness runs against a law of biology—that no organism, from an ant to a bee to a human, survives outside its community. He walks through why we've been programmed to feel separate by religion, politics, nationality, and sex, and who actually benefits when we're isolated and disempowered. A bracing reframe of the loneliness epidemic as a spiritual and biological crisis rather than a personal failing. About Dr. Lipton
