Week 10: A Doctor's 52 Week Journey to an Unprocessed Life

Week 10: A Doctor's 52 Week Journey to an Unprocessed Life Week 10 Summary: Microbiome Mastery in a Doctor's 52-Week Unprocessed Life Journey Dr. Brent W. Laartz Reflects on Paris trip (high steps, fiber via fruits/salads, minimal supplements). Focuses on **microbiome week**: Gut bacteria's role in health/longevity; impacts from ultra-processed foods, red meat (e.g., colibactin-producing E. coli linked to colon cancer 10-20 years pre-diagnosis); promotes plant-based/Mediterranean/MIND diets. Discusses inflammation/leaky gut from poor microbiota (lipopolysaccharides entering blood); personal diet: 3-4 vegan days/week, minimal red meat/dairy (some cheese), low protein + resistance training for longevity/muscle preservation. Ties microbiome to **five pillars** (diet, movement, sleep, plastics, connection): Fiber/pre/pro/postbiotics produce short-chain fatty acids (SCFAs like butyrate/propionate) for gut health, fitness, sleep; exercise enhances SCFA benefits; alcohol disrupts good bacteria; fermented foods > probiotics. Debunks myths: Fiber not "anti-nutrient"; low-protein diets (e.g., isoleucine-deficient) extend mouse lifespan 20%; avoids gym bro high-protein/carnivore/keto fads. Recaps progress (week 10/52): Berries daily, accountability app tracking, supplements (B12, omega-3, D, calcium), steel/glass kitchenware, olive/avocado oils, no packaged foods goal. **Personal updates**: Cholesterol improved; plans re-test plastics in urine post-water bottle changes; 36-48h fast weekly. Key Points and Decisions **Microbiome Health Drivers**: - Avoid ultra-processed/red meat → reduce colon cancer risk (screening now at 40). - High fiber (psyllium, inulin, raw veggies/fruits/nuts/beans) → SCFAs → healthy colonocytes, no leaky gut, better fitness/sleep. - Fermented foods (hummus, yogurt, sourdough) for persistent bacteria. - Low protein + resistance training preserves muscle in aging. **Diet Decisions**: - 4-5 vegan days/week (aim 6 by year-end); raw veggies/fruits/nuts/beans 3x/week; homemade hummus/beans; 40+ whole foods variety (berries/pineapple only fruits); 100% vegan attempt this week. - No red meat/dairy (cheese exception); beans 3x/week; 2 tbsp psyllium daily; more water. **Other Pillars**: - **Movement**: 20k steps goal (10k min); racket sports 1x/week (tennis for impact/upper body/connection); dog walks; resistance training. - **Sleep**: Rose-Thorn-Bud meditation (reframe negatives), 4-7-8 breathing, blackout room/mask. - **Connection**: Music class (Khan Academy), learn guitar/saxophone, poetry/painting, reconnect old friends (Thursday Throwback), language apps (French/Spanish/Italian). - **Plastics**: Stainless/glass pet bowls; PVA-free laundry tablets; bamboo toothbrush/toothpaste tablets; glass water dispenser. - **Fasting**: 36-48h weekly for autophagy/insulin reduction. Next Steps **Diet**: Hit 40 whole foods; 5 vegan days/week long-term; raw cashews; expand bean variety (black beans/rice). **Movement**: Racket sports (tennis courts field trip week 11); maintain running/resistance; dog walks early AM. **Sleep**: Daily Rose-Thorn-Bud + 4-7-8; better blackout/mask. **Connection/Creativity**: Khan Academy music class; instruments (bass guitar, sax); Friday poetry, Monday meditation video. **Testing/Monitoring**: Re-test cholesterol/apoB/Lp(a); plastics in urine after non-plastic water switch. **Podcast**: Week 11 field trip (tennis demo, high-impact workouts for longevity); book release post-52 weeks. **Accountability**: App tracking (vegan, greens/berries, exercise, fasting, beans/ferments, no sugar/soda/packaged).

Key Points and Decisions **Diet Decisions**: 3-5 vegan days (incl. travel); prioritize antioxidants/local organic (berries, dark chocolate); homemade dressings; poultry/seafood only if non-vegan; no fake vegan products. **Movement**: 6 days/week training (cardio/resistance); vacation exceeds routine; prep to prevent injury; join Paris run clubs (walkers welcome). **Sleep/Travel Hacks**: Blackout rooms, morning sunlight, clock advance, no afternoon caffeine. **Connection**: Local immersion (cafes, small tours/classes, expats); family cultural exposure. **Avoidances**: Plastics/chemicals (glass/stainless, organic products); processed foods/oils; non-stick pans; red meat/dairy excess; Ubers when possible. **Health Wins**: Improved metrics despite family diabetes risk; extended fasting. Next Steps Meet college friend in Paris (possible walk/Uber). Join Paris run clubs (20+ options). Take French class ("French as You Like It"). Continue 3-4 vegan days; eat crepes/dairy-free hot chocolate. Weekly Zoom calls; follow/share on gonopro.com, social media (TikTok, Instagram, Facebook, Threads, Substack, YouTube/Spotify/Apple video podcasts; Brent Williams Larson MD). Sustain pillars for longevity; audience input welcome.

Sunday Science Testosterone 2026_04_19

Sunday Science: Testosterone Therapy – Risks, Benefits & Longevity Debate Summary by Speaker Dr. Brent Laartz Discusses testosterone decline with age (0.4-2.6%/year, 30-50% by 50-60), low T ( Reviews studies: - Low T associated with 1.5-2.3x higher all-cause, CV, cancer mortality (2010 European Heart Journal cohort; 2011 JCEM meta-analysis). - Frailty mediates 35% of low T mortality risk. - Eunuch/castration studies (Korea, Poland, animals): 10-20% longer lifespan, but pre-puberty vs. late-life low T. - TRT studies: Decreased mortality if levels normalized (2012, 2015 European Heart Journal cohorts); short-term (3 years) benefit; non-normalized TRT no benefit. Notes biases in cohorts (healthy user effect); no RCTs yet. Emphasizes N=1 individualized approach considering personal risks (e.g., prostate/heart disease). Key Points and Decisions **Low Endogenous Testosterone**: Strongly linked to higher mortality (all-cause, CV, cancer); associated with frailty, metabolic issues. **Castration/Eunuch Data**: Suggests lifelong low T may extend life, but not directly comparable to adult TRT. **TRT Evidence**: Cohort studies show mortality reduction with normalized levels (esp. long-term), but short-term CV risks possible; no definitive RCTs. **No Firm Decisions**: Informational only; no endorsements for/against TRT; highlights need for RCTs to resolve controversy. Next Steps **Research**: Await randomized controlled trials (RCTs) for definitive TRT mortality data. **Individuals**: Check testosterone/health markers regularly (yearly+); consult physicians for personalized risks/benefits; prioritize resistance training, healthy lifestyle. **Audience**: Seek professional medical advice; follow show on YouTube, Spotify, Apple Podcasts, social media, goonpro.com.

Sunday Science 2026_02_08

Summary of Key Points, Decisions, and Next Steps by Speaker Dr. Brent Laartz Key Points and Decisions: Discussed several recent studies on the association between playing professional sports, particularly American football, and longevity. Highlighted the Copenhagen City Heart Study, which showed that different sports, such as tennis and badminton, can add years to one's life. Reviewed studies on elite athletes, noting that endurance sports and team sports tend to have better longevity outcomes compared to power sports. Discussed a recent study in the British Medical Journal that explored the relationship between the variety of physical activities and mortality, suggesting that a diverse range of sports may be beneficial for longevity. Next Steps: Encourage a variety of physical activities, including both cardiovascular and strength-based exercises, as well as sports that involve balance, cognitive demands, and social engagement. Emphasize the importance of finding the right balance, as too much exercise may not necessarily be better than a moderate amount. Promote the benefits of recreational sports, such as tennis and badminton, in addition to more traditional endurance activities. Explore the potential role of hormesis, where moderate levels of stress (e.g., exercise) can be beneficial, but too much may be detrimental. Encourage further research to better understand the complex relationship between physical activity, sport participation, and longevity.
