Insight | Does fasting cost you muscle? Fung, Lyon, Norton and Huberman weigh in
Jason Fung sets out to bust the muscle-loss and starvation-mode myths, while Gabrielle Lyon, Layne Norton and Andrew Huberman's fasting episodes discuss fasting alongside protein timing, protein synthesis and the needs of muscle. The answer matters for anyone who wants the benefits of fasting without giving up strength.

Michael Eisenberg covers prostate and urinary health and prostate cancer in two conversations, Rena Malik discusses prostate health with the urologist's view of the pelvis, Kyle Gillett includes the prostate in male hormone care, and Brigham Buhler takes on the fear that testosterone causes prostate cancer. Men get several perspectives in one place, including where testosterone fits.
Insight | Red and near-infrared light: what its advocates say it does
Roger Seheult links infrared light to mitochondria and melatonin, Andrew Huberman's light and skin episodes cover red and near-infrared light for skin and other tissues, Rowan Jacobsen discusses red light alongside sun and mood, and Gary Brecka builds light into his morning routine. Laying out what each claims, and the evidence they point to, helps readers judge a popular wellness tool.
Insight | Seed oils on trial: Norton, St-Onge and Brecka weigh in
Layne Norton takes up seed oils in his conversations with Andrew Huberman, Marie-Pierre St-Onge discusses them alongside the problem of industry-funded research, and Gary Brecka groups them with everyday toxins. Setting the positions side by side shows what evidence each one leans on.
Insight | Your brain talks to your immune system: breathing, heat and memory
Andrew Huberman's immune episodes describe how the nervous and immune systems signal each other, with tools from sauna to cyclic hyperventilation and its E. coli study, Max Krummel describes memories that can recall immune states, and Huberman's pain episodes cover Wim Hof breathing, the stress response and inflammation. It suggests that part of immune defense can be steered through the nervous system.
Insight | The fat you can't pinch: why visceral fat worries so many experts
Rhonda Patrick, Stacy Sims, William Li, Shawn Stevenson, Mary Claire Haver and Robert Lustig each separate the deep fat around the organs from the fat under the skin, and several explain how to spot it, from the idea of being skinny fat to the three fat depots, and how to bring it down. Knowing which fat is which changes what a reader tracks and explains why the scale alone can mislead.
Insight | Code is written for people: Knuth, Guido and the Hitchhiker's Guide on readability
Donald Knuth explains in two conversations why he writes programs as literature through literate programming, Guido van Rossum describes programs as recipes written for two audiences and digs into code readability, and The Hitchhiker's Guide to Python devotes its core chapters to writing and reading great code. Treating the human reader as the main audience changes how programmers name, structure and explain their work, and makes code easier to maintain.
Insight | Why AI runs on Python: NumPy's creator, Anaconda's CEO and Mojo's designer explain
Travis Oliphant tells how NumPy united a split community and became the foundation of array and tensor computing in Python, Peter Wang explains what made him fall in love with Python and why the scientific Python stack emerged as it did, and Chris Lattner builds Mojo as a superset of Python because of Python's strengths. Their accounts explain how a language designed for readability ended up as the working language of science and AI, and what its builders are doing about its speed.
Insight | Written for people first: readability, indentation and great Python code
Guido van Rossum describes programs as recipes written for two audiences and explains why readability matters, Chris Lattner weighs Python's strengths and the indentation debate while building Mojo on top of it, and The Hitchhiker's Guide to Python gives whole sections to writing and reading great code. Together they show why the people who build and teach Python treat code as something humans must read, not only something a machine must run.
Insight | Do it first thing: why habit builders give the morning to what matters
Mel Robbins makes doing a new habit in the morning one of her five systems for making it stick and builds her Million Dollar Morning around moving and making progress before checking the phone, Robin Sharma's The 5AM Club argues that owning your first hour can transform your whole life, and John Grisham tells how one page a day at 5 a.m. turned a small-town lawyer into a bestselling novelist.

Insight | Melatonin as the body's calendar: light, seasons and mood
Andrew Huberman's light episodes describe melatonin as the body's seasonal calendar, his episode on time perception calls circannual entrainment a calendar written in melatonin, his office-hours answers link seasons, melatonin, serotonin and mood, and Samer Hattar takes up night waking, melatonin and seasons with him. Seeing melatonin as a signal of the time of year, not just a sleep switch, helps explain why mood shifts with the seasons.
Insight | Cancer risk you can change: screening, metabolism, alcohol and immune defenses
Jason Fung describes cancer as a seed that needs the right soil, Peter Attia and Chris Thompson argue for earlier and better screening, and immunologists explain why tumors slip past the body's defenses.

Insight | Never too late: what starting to train after 50 delivers
Vonda Wright rejects the idea that decline is inevitable, Layne Norton and Pavel Tsatsouline explain how to lift safely later in life, and performers in their seventies describe getting stronger than they were at 50. Their accounts answer the common worry that the window for building strength has already closed.
Insight | Turning Back the Clock: Age Reversal, Escape Velocity and What Is Actually Proven
David Sinclair reports that a cellular reprogramming therapy has entered its first human trial, Ray Kurzweil forecasts more than a year of added life expectancy per year by the end of the decade, and Nick Bostrom and Michael Levin add what ending aging would demand and another biological route to it. The sources contain no outside critic of these claims, so this piece sorts each one by its evidence: shown in animals, shown in human cells, under test in people, or still a prediction.
Insight | Your mouth is a health organ: oral bacteria, fluoride and whole-body disease
Dentist Staci Whitman and Huberman's oral health episode treat the mouth as a living ecosystem that teeth repair within, and warn that harsh mouthwash and constant snacking damage it, while James Nestor ties shrinking jaws to breathing problems. Looking after the mouth turns out to protect far more than teeth.
Insight | Erectile dysfunction as an early warning: blood flow, not hormones
Urologists Michael Eisenberg and Rena Malik say most erectile problems come from blood vessels and the pelvic floor and often appear before heart disease does, and Kelly Starrett and Kyle Gillett add the movement and lifestyle side. Men who treat it as a health signal get a chance to fix the cause early.
Insight | Growth hormone: the youth hormone that may not lengthen life
Clinics offer growth hormone and drugs that release it to restore youthful muscle and skin, and Kyle Gillett and Craig Koniver describe using them, yet David Sinclair notes that lower growth signaling goes with longer life and Huberman lists the risks of injecting it. The contrast shows why feeling younger and living longer are not always the same goal.
