    Episode 399: Urolithin A, Mitochondrial Health, and Nutrition for Pro Athletes — Dr. Emily Werner

    10/08/2026 | 1h 9 mins.
    Emily Werner, PhD, RD, CSSD, IFNCP is Team Dietitian for the Philadelphia 76ers (NBA) and Philadelphia Flyers (NHL), and Nutrition Affairs Sport Lead at Timeline.

    Dr. Emily joins Dr. Mike to unpack postbiotics, urolithin A, and why mitochondrial health matters for pro athletes and everyday people alike, digging into the real research behind Timeline's Mitopure and why chasing $200K gadgets rarely beats getting the fundamentals right.

    Expect to learn what a postbiotic actually is and how urolithin A differs from other supplements, why old-school and new-school sports dietitians disagree on peptides and supplement fads, how chronic undereating quietly undermines performance in women's sports, what the current human performance research on urolithin A actually shows, how Mitopure is dosed and why urolithin A can't be reliably food-sourced, and why product quality and manufacturing integrity matter more than marketing claims, and much more.

    Getting Back to Nutrition Basics: Gut Health, Micronutrients & Training with Zach Moore

    04/08/2026 | 1h 16 mins.
    Zach Moore is a nutrition and exercise coach based in southern Indiana, coaching clients online and in person.

    Zach cuts through the noise of complicated programming and diet protocols to get back to what actually works — minimalist strength training, honest macro-setting, and paying attention to gut health and micronutrient status before chasing anything fancier.

    Expect to learn how to build serious strength with far less training volume than you think, why chasing perfect programming conditions is often a waste of energy, how Zach sets carbohydrate and macro targets for real-world clients, when (and when not) to bother with micronutrient or gut testing, and why micronutrients matter even on restrictive or elimination diets, and much more.

    How elite bodybuilders think about problem-solving, business and nutrition with Coach Cliff Wilson

    27/07/2026 | 1h 15 mins.
    Cliff Wilson is a physique coach with over 16 years of experience working with bodybuilders and physique athletes of every level, including 24 world champions and the current natural bodybuilding world champion.

    Getting better doesn’t make hard things feel easier—it makes you capable of doing more. Cliff Wilson explains the mental skills behind elite physiques, why context beats internet absolutes, and how great coaches turn research, experience, and failure into better decisions.

    Expect to learn why impulse control makes up 20–50% of physique coaching, why you have to learn to dribble before you try to dunk, why practitioners and social media commentators are not the same thing, why getting fitter never makes a true max effort feel easier, how context (not absolutes) explains wildly different carb intakes between world-class physique athletes, why most advanced bodybuilders eventually land back on a bro split, and what separates “collectors” of credentials from coaches who can actually integrate and apply what they know—and much more.

    Are Your Peptides Illegal? — Rick Collins — #396

    22/07/2026 | 1h 8 mins.
    Rick Collins, Esq., NSCA-CSCS, is a lawyer who defends the nutrition and fitness community, a partner at Collins Gann McCloskey & Barry PLLC, and General Counsel to the International Society of Sports Nutrition.

    Peptides are everywhere right now, but most of what's sold online as BPC-157 or TB-500 is illegal — and the FDA is about to decide what happens next. Rick breaks down the science, the legal gray market, and why the military's new testosterone screening policy matters too.

    Expect to learn what actually counts as a "peptide," how GLP-1 drugs normalized injectable medications and fueled the gray market, what the FDA's own scientists concluded about BPC-157 and TB-500, why Rick's caseload has shifted from steroids to 80-90% peptide cases, what a possible "experimental peptide" middle-ground category could look like, and what really happens when the FDA raids a peptide seller, and much more.

    What Coaching Air Force Pilots Taught Me About Real Performance — Sam Brown — #395

    20/07/2026 | 1h 14 mins.
    Samuel Brown, M.Ed., CSCS is a Cognitive Performance Specialist for the U.S. Air Force and a strength and conditioning professional who has worked everywhere from collegiate athletics to elite tactical units.

    Sam spends his days training Air Force pilots and aircrew who run on nicotine, caffeine, and alcohol — and almost never turn off their nervous system. In this episode he reveals why the toughest operators need recovery just as much as intensity, and what years of coaching in Altus, Oklahoma taught him about real performance under extreme cognitive load.

    Expect to learn what Air Force pilots are actually like to train, why the nicotine-caffeine-alcohol "trifecta" dominates military performance culture, how the physical act of flying itself takes a hidden toll through vibration and posture, why sympathetic nervous system domination cements poor posture and movement patterns, how Sam sneaks down-regulation into hard training sessions disguised as recovery work, and why resting heart rate might be a better performance metric than any wearable, and much more.
