    Why This Surgeon Says Healthcare Starts Too Late | Darshan Shah, MD

    He started medical school at 15. Graduated as a doctor at 21. Did over 10,000 surgeries. Then walked away from the operating room to build something he thinks can actually fix healthcare. Jon Bier sits down with Dr. Darshan Shah, board-certified surgeon, founder of Next Health, and one of the most grounded longevity voices in a space that desperately needs grounding. Next Health is now 20 locations and growing, built on a simple premise: don't wait until you're sick to think about your health. Come in when you're healthy and keep it that way. This conversation covers the full arc. The kid who was severely bullied in a New Jersey high school where he was one of two brown kids. The surgeon in his early 20s getting side-eyed in operating rooms. The moment he realized the sick-care system was unfixable and decided to build a parallel one instead. And the new book, Your New Health OS, that makes the case for using AI and personal data to completely rethink how you manage your own health. Dr. Shah is not jaded. That might be the most impressive thing about him. In this episode: - Why the American healthcare system is unfixable from the inside, and why building a parallel system focused on longevity and health optimization is the only real solution - What it looks like to enter medical school at 15, train at the Mayo Clinic, do over 10,000 surgeries, and then pivot entirely to preventive medicine because the operating room is treating the wrong problem - How AI is about to unburden doctors, empower patients, and fundamentally change what it means to take care of your health, including the first fully AI-enabled autonomous surgery that just happened Find Dr. Shah & Next Health: - Dr. Shah on Instagram: https://www.instagram.com/darshanshahmd/ - Dr. Shah's website: https://www.drshah.com - Next Health: https://www.next-health.com - Next Health on Instagram: https://www.instagram.com/nexthealth/

    How Rorra Built an 8-Figure Water Filter Brand in Its First Year | Brian Keller & Charlie Carlisle

    The water filter category hasn't meaningfully changed in forty years. Every pitcher looked the same. Every one was made of plastic. Nobody could tell you what was actually in your water, or what the filter was actually removing. Jon Bier sits down with Brian Keller and Charlie Carlisle, co-founders of Rorra, the brand reimagining water filtration from the ground up, for a conversation about what happens when personal experience turns into a company. Brian's daughter Aurora developed eczema with no known cause shortly after birth. Charlie faced lead contamination in Denver's water supply. They went looking for a solution, couldn't find one they trusted, and spent three years building it themselves in glass and stainless steel, with NSF-certified filtration and an Andrew Huberman partnership to show for it. Before Rorra, they built Love Your Melon into a brand that donated nearly $10 million to pediatric cancer before getting acquired. They know how to build something real. And they think clean water is the most overlooked pillar in the entire wellness conversation.They're probably right. In this episode: - Why the water filtration category is one of the last places in wellness where nobody has built a brand worth talking about, and what it actually takes to change that - The personal stories behind Rorra: two kids with unexplained eczema, one lead contamination problem in Denver, and a combined realization that the solution didn't exist yet - What three years of engineering, design iteration, and filtration research taught two founders who came from hats, and why starting from scratch as a consumer was actually the advantage Find Brian, Charlie & Rorra: - Brian on Instagram: https://www.instagram.com/briandkeller7/ - Charlie on Instagram: https://www.instagram.com/charliecarlisle_/ - Rorra: https://www.rorra.com - Rorra on Instagram: https://www.instagram.com/rorrawater/ Timestamps: 0:00 – What's actually in your tap water 0:35 – Introducing Brian Keller and Charlie Carile of Aurora 4:57 – The personal water problems that led them to start Aurora 7:57 – Three years of R&D before ever launching 10:17 – Raising their first round with no sales yet 17:00 – Eight figures in revenue in year one 20:56 – Designing appliances to last decades, not a year 26:18 – How they actually use AI (and where they don't) 30:42 – Why every city's water problem is different 37:27 – How forever chemicals accumulate in the body 48:07 – Aurora's vision for a fully integrated water platform

    What You Need to Fix Before Taking Another Supplement l Dr. Wiegers

    Most people in the wellness space are trying to get from 91 to 100. Nobody's talking about how to get from 0 to 90. Jon Bier sits down with Dr. Jeff Wiegers — double board-certified anesthesiologist, interventional pain specialist, and regenerative medicine expert at BioReset Medical, for a conversation about what it actually means to pursue longevity when most of the market is selling you the shortcut. Jon and Jeff met in Cabo over a $25,000 experimental gene therapy shot. This is the follow-up conversation they should have had before that trip and it's better for it. Peptides. Stem cells. Gene therapy. GLP-1s. Growth hormone. These are the things everyone is talking about and almost nobody is contextualizing correctly. Jeff is one of the rare doctors who will slow down, ask the foundational question, and tell you when the answer is actually just: go outside, eat real food, and sleep. The cutting edge is real. But most people haven't fixed the basics yet. In this episode: Why the peptide boom needs a reality check — what unregulated sourcing actually means, why lead has shown up in tested products, and how to think about trust as the most important factor in this space - The difference between chasing a number and fixing the underlying reason the number is off and why most longevity protocols skip the most important question - What reversible gene therapy, Muse cells, and the next generation of regenerative medicine actually look like and why the delivery method revolution might matter more than the therapies themselves Find Dr. Wiegers & BioReset: - Dr. Wiegers on Instagram: https://www.instagram.com/jeffwiegers/ - BioReset Medical: https://www.bioresetmedical.com - BioReset on Instagram: https://www.instagram.com/bioresetmedical/

    How to Build a $100M+ Brand Without Losing Its Soul | Kent Yoshimura & Ryan Chen

    A neuroscience student mixing supplements in his dorm room. A national kendo competitor who became paraplegic at 19 after a snowboarding accident. Best friends. And then, one scuba diving Groupon later — a company.Jon Bier sits down with Kent Yoshimura and Ryan Chen, co-founders of Neuro, for a conversation ten years in the making. Jon was there early. He gave them his first ever angel check. He watched the whole thing — the grinding first seven years on $1.6 million raised while every other DTC brand was burning through $30 million, the Shark Tank appearance that got them zero deals and exploded their sales, the trademark lawsuit that nearly ended everything, the near-billion dollar brand they built without ever compromising the formula. This isn't a success story. It's a story about what success actually looks like when you build it the right way — slowly, stubbornly, and with your friendship completely intact. Jon has been saying it for a decade. This is the episode where everyone else gets to hear why. In this episode: • How Neuro went from clinical trial side income and Craigslist employees to one of TikTok's top-selling brands and why raising less money than everyone else turned out to be the advantage • The Shark Tank story nobody tells: zero deals, a trademark lawsuit, a cold DM to a billionaire, and the moment everything changed • Why Kent and Ryan have never cut a corner on the formula and what it actually means to be a brand-led company in a world that rewards sales-led thinking Find Kent, Ryan & Neuro: • Kent on Instagram: https://www.instagram.com/kentaro/ • Ryan on Instagram: https://www.instagram.com/ryan.ryc/ • Neuro: https://www.getneuro.com • Neuro on Instagram: https://www.instagram.com/neurogum/

    How She Built A Water Brand Disrupting A 1B$ Market | Clara Sieg

    Sponsored By:→ Neuro | Go to ⁠https://getneuro.com⁠ and use code ONEDAY at checkout for 15% OFF your entire order. You're optimizing your supplement stack. You're tracking your macros. You're sleeping eight hours. And you're washing it all down with water that's sitting in plastic that's been baking on a truck in 100 degree heat for three weeks. Jon Bier sits down with Clara Sieg — co-founder of Loonen and former venture investor — for a conversation about the most overlooked input in the entire wellness conversation. Water. The category that built its entire identity on pictures of waterfalls and asked consumers to just trust them. Clara got pregnant, started paying attention, and found out that no natural source in the US she tested was entirely free of contaminants. So she built something that paired spring sourcing with stainless steel processing, physical membrane filtration, and NSF certification — and put it in glass. Every time. This isn't fear mongering. It's just information and most people don't have it.In this episode:• Why 50% of US tap water tests positive for lead and forever chemicals and why the bottled water sitting in plastic on a hot truck might not be solving the problem you think it is• How Clara went from a panic during pregnancy to six months testing water sources across the US, and why every single one had a footnote• What it actually takes to build a cleaner water brand in the most competitive, public-company-dominated beverage category on the shelf and why being naive enough to start was an advantage.

    The Startup Disrupting a $7 Trillion Industry l Jess Haghani

    Sponsored By: → Neuro | Go to ⁠https://getneuro.com⁠ and use code ONEDAY at checkout for 15% OFF your entire order. Every single grocery store aisle has been disrupted by better-for-you brands. Every one — except the aisle where the fastest-growing demographic in America shops for nutrition. Jon Bier sits down with Jess Haghani — founder and CEO of Lucille Health — for a conversation about what happens when you spot a gap so obvious it feels impossible that no one has filled it yet. Jess watched her grandmother, Lucille, come home from heart surgery and get handed the same ultra-processed nutrition shakes that haven't meaningfully changed since the 1970s. Products people hide in their basements. Products they're embarrassed to let their grandkids see. A $6 billion category with zero dignity, zero innovation, and no real competition. So she left KKR, went to Harvard Business School, and built the brand she knew had to exist. This episode is a little different. Jess hasn't built a nine-figure business yet. But Jon believes she will and this conversation is why. In this episode: • Why less than 1% of food and beverage innovation is happening for older adults, despite them being the fastest-growing consumer demographic in the world — and why that gap is finally closing • The real story behind Lucille: how watching her 92-year-old grandmother hide a nutrition shake in her basement became the founding moment of a brand built around dignity • What it looks like to take on Abbott and Nestlé with no money, no formulation experience, and no playbook and why that might actually be the advantage Find Jess & Lucille: • Jess on Instagram: https://www.instagram.com/jesshaghani/ • Lucille Health: https://www.lucillehealth.com • Lucille on Instagram: https://www.instagram.com/lucillehealth/ Timestamps: 0:00 - Intro 1:21 - Jon's personal experience with his dad's hospital nutrition 2:04 - Why do hospitals still serve such poor nutrition products? 7:43 - The corruption of big incumbents like Abbott and Nestle 9:59 - How big is the older adult nutrition market? 11:01 - Why has this category never been disrupted? 11:38 - The shame and stigma around products like Ensure and Boost 15:25 - Jess's background: London, real estate, KKR, HBS 17:02 - The story of Lucille, Jess's 92-year-old grandmother 19:51 - Assembling the team and figuring it out step by step 25:00 - Should founders pay themselves a salary? 31:04 - The broader vision: beyond beverages, full category disruption 37:23 - The 70+ demographic has the highest retention rate 43:18 - Jon's confidence in Lucille Health's future

    He Built a $110 Million Brand in a Market That Didn’t Exist l Michael Brandt

    Sponsored By: → Neuro | Go to ⁠https://getneuro.com⁠ and use code ONEDAY at checkout for 15% OFF your entire order. Description He licensed technology from Oxford, sold it to Navy SEALs and the US Department of Defense, brought the price from $30 a shot to $5, and is now stocking shelves at Chevron and Equinox. This is what it looks like to create a new category from scratch and refuse to stop. Jon Bier sits down with Michael Brandt — Stanford CS grad, 2:35 marathoner, and co-founder and CEO of Ketone-IQ — for one of the most genuinely nerdy, genuinely exciting conversations about building a brand that didn't exist before. Jon helped launch Ketone-IQ early on and didn't invest. He'll tell you that himself. This is the conversation where he probably fully processes that decision. Ketones aren't a trend. They're a nutritional primitive — a new macronutrient. The kind of thing you can't speed-run. And Michael Brandt is the rare founder who built his entire business philosophy around that truth. The category is coming. They just got here first. In this episode: • Why creating a new category is a decade-long bet — and why that's exactly the right bet if you want to build something fundamental instead of fast • How Ketone-IQ went from a $6M DoD contract and $30-a-shot margins to nationwide grocery stores and a near-half-billion-dollar valuation • What Jon and Michael actually talk about when they talk about celebrity deals, brand equity, and why the brands nobody can name are the real cautionary tale Find Michael & Ketone-IQ: • Michael on Instagram: https://www.instagram.com/michaeldbrandt/• Ketone-IQ: https://ketone.com• Ketone-IQ on IG:https://www.instagram.com/ketone/ Timestamps: 0:00 - Building a New Category From Scratch: Why It's Harder (and Bigger) Than Anything Else 1:18 - How Ketone IQ Started: Oxford, the Military, and $30-a-Shot Pro Athletes 4:01 - What Ketones Actually Do and Why Michael Got Obsessed 7:08 - The DoD Relationship: Research, Procurement, and On-Base Retail 8:02 - The Early Positioning Problem: Ketones ≠ the Keto Diet 10:22 - Why Sampling Is Everything for a Product You Actually Feel 13:36 - Jon Bier's Regret: Why He Didn't Invest (And Why the Odds Were Against It) 15:18 - How Marathon Running Gave Michael the Belief to Do the Impossible 21:25 - The First Sign of Real Momentum: People Who Tried It Couldn't Stop 23:17 - "We're Not Selling Ketones — We're Selling a Feeling" 25:03 - Grün, Element, and How to Win Without a Product People Can Feel 29:27 - Trend Proof vs. Trend Dependent: Why Ketones Are a Nutritional Primitive 32:43 - How Jon Bier Spots Winners (And Why Most Brands Fail Because They're Too Early) 35:26 - How to Cannibalize Yourself Before a Competitor Does 39:10 - The Jake Paul and Jeff Wu Connection (and the Antifund Story) 41:43 - What the Rogan Partnership Actually Means for a Brand 45:40 - Why DTC Alone Is Dead and Retail Is the Startup Within the Startup 49:08 - Why the Brands That Won DTC Stopped Innovating 53:26 - How Celebrity Ambassadors Unlock Retail Doors 56:03 - What Retailers Actually Want to Hear (It's Not About the Product) 1:00:07 - Why Big Companies Destroy the Brands They Buy 1:02:50 - Where Ketone IQ Is Now and What the Exit Math Looks Like 1:05:10 - What Michael Would Actually Do With the Money

    Why Health Optimization Is Going Too Far l Simon Hill

    Sponsored By: → Neuro | Go to https://getneuro.com and use code ONEDAY at checkout for 15% OFF your entire order. The wellness internet runs on fear. Simon Hill doesn't. Jon Bier sits down with Simon Hill — physiotherapist, nutritionist, host of The Proof podcast, and one of the most genuinely balanced voices in a space that rewards extremism — for a conversation about what the science actually says versus what gets clicks. Peptides. GLP-1s. Testosterone. Longevity. IGF-1. Seed oils. These are the topics everyone is shouting about right now, and Simon is one of the few people who will actually slow down and read the evidence before forming an opinion. This isn't a conversation about fear. It's a conversation about clarity — and why the most dangerous thing in health right now might be the confidence with which people are saying things they don't actually know. Jon brings the curiosity. Simon brings the receipts. The result is one of the most honest conversations about longevity, biohacking, and what it means to actually take care of yourself that you'll find anywhere. In this episode:  • Why the peptide boom deserves more caution than the wellness world is giving it — and what the IGF-1 and cancer research actually says about forcing the system  • The CT scan technology that can now detect vulnerable plaque before a heart attack happens, and why Simon's dad's heart attack at 41 put him on this path  • What genuine longevity thinking looks like when you strip away the extremism — and why the most important health decisions often come down to individual risk tolerance, not universal rules Find Simon:  • Instagram: https://www.instagram.com/simonhill/  • The Proof Podcast: https://www.theproof.com  • The Proof on Instagram: https://www.instagram.com/theproof/ Timestamps: 0:00 - Intro 0:49 - Why Jon Thinks About His Mom When He Creates Content 2:10 - The Peptide Warning That Started a Debate 4:44 - What the New Yorker Found When They Third Party Tested Peptides 7:45 - Why Whoop Was the Best Investment He Ever Made 11:47 - RFK, Compounding Pharmacies, and Why Regulation Could Help 16:58 - Why Longevity Matters and What He's Missing in the Meantime 23:37 - The Day His Dad Had a Heart Attack at 41 27:00 - How AI Is Revealing the Real Story Inside Your Arteries 41:49 - Why Most Supplements Are Useless Until You Do the Basics 48:42 - The Creatine Gummy Scam Nobody Saw Coming 1:01:29 - He Was on Testosterone When He Tried to Have Kids.
