Biohacking

A practical framework for upgrading brain energy and performance through mitochondrial optimization.

Core Premise

High performance starts with cellular energy. The brain consumes up to 20 percent of the body’s total energy. When mitochondria weaken, focus drops, fatigue rises, and decisions suffer. The book treats these issues as fixable hardware problems rather than personal shortcomings.

Key Insights by Section

Head Start
Fatigue, cravings, brain fog, and mood swings are symptoms of low brain energy. Remove brain kryptonite (certain foods, lights, toxins) first. Prioritize high-impact decisions early before daily decision fatigue sets in. Reduce environmental stimuli during deep work blocks.

Mighty Mitochondria
Mitochondria produce ATP, the energy currency of the cell. Efficiency declines with age, but the process is hackable. Support comes from proper nutrition, stable blood sugar, hormone balance, and toxin reduction. Test thyroid and blood sugar if energy consistently crashes.

Become a Neuromaster
Neurons require massive ATP and quality fats for myelin production. Build new neurons through BDNF-supporting habits: strategic exercise, polyphenols, and enriched environments. Gut health directly influences prefrontal cortex myelination.

Inflammation: The Muffin Top in Your Brain
Chronic low-grade inflammation silently degrades cognition years before disease appears. Address it by healing the gut barrier, removing inflammatory triggers, and using polyphenols and cold exposure. Lymphatic drainage during sleep clears brain waste.

Brain Fuel
Run on clean fats and ketones for steady energy. Prioritize grass-fed meats, wild fish, pastured eggs, low-toxin coffee, and colorful produce. Medium-chain triglycerides (like Brain Octane) provide fast fuel without blood sugar spikes.

Brain-Inhibiting Foods
Avoid mold toxins (common in grains, coffee, nuts), trans fats, oxidized vegetable oils, excess sugar, and artificial additives. These directly impair mitochondrial function and increase inflammation.

Avoid Toxins and Improve Detox
Heavy metals, mycotoxins, and environmental chemicals drain mitochondrial energy. Support natural detox pathways with sweating, targeted supplements, and careful avoidance. Test and remediate mold exposure if symptoms persist.

Your Brain on Light, Air, and Cold
Block junk light (especially blue at night) to protect mitochondria and circadian rhythm. Use red-spectrum lighting in evenings. Practice controlled cold exposure and hypoxic breathing for resilience. Optimize indoor air quality.

Sleep Harder, Meditate Faster, Exercise Less
Deep sleep clears metabolic waste via the glymphatic system. Short, intense exercise and meaningful movement build BDNF more effectively than long cardio. Meditation and breathwork calm the nervous system and enhance recovery.

The Two-Week Program
Combine high-fat meals, light hygiene, cold showers, targeted supplements (magnesium, creatine, PQQ), and consistent sleep. Results compound quickly in energy, focus, and mood.

Beyond the Limits
Once basics are dialed in, explore advanced tools like neurofeedback, ozone, or nootropics. The goal is consistent ownership of your biology rather than fighting it.

Final Takeaway
Small, consistent upgrades to mitochondrial function create outsized gains in daily performance. Treat your brain like critical infrastructure: fuel it cleanly, remove drag, and monitor results. Two weeks of focused changes reveal what steady high performance actually feels like.
