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).

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 (<250-300 ng/dL) linked to metabolic syndrome, obesity, increased mortality.

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 (<2-9 months) neutral/possible risk, long-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.

Summary of Key Points, Decisions, and Next Steps

Dr. Brent Laartz

Key Points and Decisions:

Entrainment involves the use of auditory or visual stimulation to influence brain wave patterns associated with different states of wakefulness, concentration, relaxation, and sleep.

Gamma waves (40 Hz) are associated with concentration and wakefulness, while theta and delta waves are associated with relaxation and sleep.

Multiple studies have shown that 40 Hz gamma wave entrainment, using either light sources or binaural beats, can have positive effects on Alzheimer's disease and cognition.

Theta wave entrainment, using either isochronic tones or binaural beats, can improve sleep quality and post-sleep state, as demonstrated in a study on young elite soccer players.

Next Steps:

Continue exploring the research on the effects of different brain wave entrainment techniques on sleep, cognition, and overall well-being.

Potentially incorporate these entrainment methods into personal practice or recommend them to patients, while emphasizing the importance of consulting with healthcare professionals before making any significant changes.

Expand the discussion on Sunday Science to cover a wider range of evidence-based approaches to improving health, diet, exercise, and longevity.
