Reclaim strength, vitality, and focus in a plastic, ultra-processed world
I’m Gert Louw. I don’t do lukewarm. We live in an age where men are softer, sicker, and more distracted than ever—and the data backs it.
Large-scale analyses show a decades-long, age-independent decline in men’s testosterone, even in “healthy” populations. The latest 2025 synthesis covering over a million men reports a progressive drop in total testosterone (and LH), suggesting a system-level reset of the male hormonal axis.
It gets worse. Microplastics have been found in every human testicle sampled in a 2024 study—polyethylene and PVC showing up where no plastic belongs. The same year, NEJM reported micro- and nanoplastics embedded in carotid artery plaque, with a ~4.5× higher risk of heart attack, stroke, or death over the next ~3 years when plastics were present. This is the first human data linking vascular plastic load to events.
Nutrition? A 2024 BMJ umbrella review ties ultra-processed food exposure to higher risks across cardiometabolic disease, mental health disorders, and all-cause mortality. Translation: the more your food was built in a factory, the more it erodes you.
And if you’re burning the midnight oil: just one week of sleeping ~5 hours/night slashes daytime testosterone by 10–15% in young men—roughly the hit from a decade of aging. Sleep is not “optional.” It’s anabolic.
So yes—the headwinds are real. But so is the way out.
The non-negotiables
1) Chase fitness that predicts survival.
Cardiorespiratory fitness (VO₂max) is dose-dependently tied to longevity—no observed upper limit of benefit in a landmark JAMA cohort. Get fitter, live longer. Period.
2) Get strong and stay strong.
Muscle-strengthening work cuts premature death risk. The sweet spot from multiple cohort meta-analyses: ~30–60 minutes/week of resistance training shows the biggest mortality reduction (J- or U-shaped curve—more isn’t always better). Combine it with aerobic work for even larger benefits.
3) Eat like your life depends on it—because it does.
Aim for ~1.6–2.2 g protein/kg/day (if you’re training), and hit per-meal leucine thresholds: ~0.4 g protein/kg/meal(older lifters may need the high end). This distribution maximizes muscle protein synthesis; going above ~1.6 g/kg/day doesn’t add more hypertrophy for most.
4) Wage war on plastic exposure and fake food.
Cook real food. Don’t heat food in plastic. Use glass/steel for storage. Filter water. Every reduction counts while we learn more about mechanisms.
The Man-Maker Protocol (8 weeks to reset your trajectory)
Weekly structure (repeat x8):
- 3 strength days (45–60 min):
- Day A: Squat + Pull-ups (or assisted) + Loaded Carries
- Day B: Hip Hinge (trap bar DL) + Row + Split Squat
- Day C: Press (incline or overhead) + Chin-ups/Lat Pulldown + Hip Thrust
- Work sets: 3–5 per lift, RIR 1–2 (leave 1–2 reps in tank).
- 2 Zone-2 days (40–60 min): conversational pace cycling, incline walk, or row.
- 1 Sprint/Power day (15–25 min): 6–10 × 10–20s uphill sprints or bike sprints; full recovery.
- 1 Long walk / Mobility day (60–90 min): nasal breathing, sunlight.
Why this mix?
You get the mortality protection of aerobic capacity plus the metabolic armor of muscle, with minimal joint tax. It matches the evidence: cardio fitness for lifespan, strength for healthspan.
Eating to build the man
Targets:
- Protein: 1.6–2.2 g/kg/day, ~0.4 g/kg per meal, include ≥2–3 g leucine from high-quality sources (whey, eggs, dairy, lean meats, or well-designed plant blends).
- Carbs: time most around training; 2–4 g/kg depending on volume and leanness goals.
- Fats: fill the remainder with mostly mono- and saturated from whole foods; limit seed-oil-heavy UPFs.
- Food rules: single-ingredient foods 80–90% of intake; UPFs are weekend guests, not roommates.
Example for 90 kg lifter (cut/recomp):
- Breakfast (post-training): 36 g whey isolate + Greek yogurt + blueberries + oats.
- Lunch: beef sirloin, potatoes, veg, olive oil.
- Snack: cottage cheese + fruit.
- Dinner: salmon, rice, salad.
- Pre-bed (optional): casein or skyr.
Sleep like an athlete (because you are one)
- 7.5–9 hours in a dark, cool cave.
- Anchor wake time. Caffeine cutoff 8 hours before bed; devices off 60–90 min prior.
- Track morning erections, mood, training drive—cheap proxies for endocrine health.
Remember: a week of short sleep can dent T by 10–15%.
Plastic & pollutant minimizers (simple wins)
- No plastic + heat. Don’t microwave or dishwash plastics; hot fat + plastic = bad combo.
- Glass/steel for storage and water bottles.
- Loose-leaf or paper filter tea/coffee; avoid plastic mesh where possible.
- Vent & vacuum: dust harbors plastic fibers; HEPA vacuum weekly.
These are pragmatic steps while science unpacks causality; human vascular data are already alarming.
Bloodwork & checkpoints (every 8–12 weeks)
- TT, FT, SHBG, LH, lipids/apolipoproteins, fasting insulin/A1c, hs-CRP, CMP, CBC, vitamin D.
- Track: waist (navel), pull-up max reps, 2 km row time, resting HR/HRV, and bodyweight photos under same lighting.
- If TT or FT sag while training/sleep/nutrition are dialed, escalate with a clinician.
Final word
Strength is not vanity; it’s stewardship. Build VO₂max. Build muscle. Eat real food. Sleep like it’s your job. Reduce plastic exposure. Get your labs. Repeat for decades.
I’ll see you in the gym—and on the mountain.
