biohacking

December 23, 2025 (5d ago)

biohacking is about aligning with biology, not forcing extremes

it is mostly about removing friction, not adding hacks

consistency beats novelty every time

core principles

  • fix sleep, light, food, movement, stress before supplements
  • measure only what you can act on
  • avoid injections, experimental drugs, or extreme interventions
  • favor habits with long human safety records
  • stop anything that worsens sleep, anxiety, or recovery

sleep (highest roi)

  • sleep is the foundation everything stacks on
  • fixed wake-up time > fixed bedtime
  • morning sunlight within 30–60 minutes of waking
  • no bright or overhead light 2–3 hours before bed
  • cool, dark, quiet bedroom
  • caffeine cutoff 8–10 hours before sleep
  • alcohol framed as a sleep disruptor, not relaxation

circadian rhythm

  • light is the primary biological clock
  • outdoor daylight beats light boxes when possible
  • dim evenings support melatonin release
  • late-night screens = artificial jet lag
  • consistent meal timing reinforces circadian alignment

nutrition

  • fewer rules, more signal
  • whole foods over supplements
  • protein sufficiency for muscle, satiety, glucose stability
  • fiber for gut and metabolic health
  • minimize ultra-processed foods rather than chasing superfoods
  • time-restricted eating used cautiously, not dogmatically
  • hydration guided by thirst + urine color

glucose awareness (without obsession)

  • glucose spikes are context-dependent, not moral failures
  • walking after meals improves glucose handling
  • pairing carbs with protein/fat blunts spikes
  • avoid anxiety-driven continuous tracking

exercise (the real backbone)

movement baseline

  • daily movement is non-negotiable
  • steps and light activity matter even if you train
  • long sitting blocks blunt metabolic health

resistance training / lifting

  • primary goal: preserve and build muscle mass
  • muscle = metabolic health, insulin sensitivity, longevity
  • 2–4 sessions per week is sufficient
  • compound movements prioritized (squat, hinge, push, pull, carry)
  • progressive overload > novelty
  • form and consistency beat ego lifting

cardio

  • cardio is for heart, mitochondria, and brain
  • not all cardio is the same
zone 2 cardio
  • low to moderate intensity, conversational pace
  • improves mitochondrial density and fat oxidation
  • 2–4 hours per week total
  • examples: brisk walking, cycling, easy jogging, rowing
high-intensity cardio
  • short, hard efforts raise cardiovascular ceiling
  • improves vo2 max
  • 1–2 sessions per week max
  • excessive hiit = stress accumulation

vo2 max

  • one of the strongest predictors of lifespan and healthspan
  • reflects heart, lung, blood, and muscle integration
  • improves via intervals, hills, mixed endurance + strength
  • progress stalls without sleep and recovery

recovery

  • adaptation happens during rest, not training
  • sleep, calories, and protein enable gains
  • soreness is not a success metric

stress & nervous system

  • chronic stress treated as a root cause
  • slow nasal breathing > complex breath protocols
  • regular time without digital input
  • social safety and trust affect biology

cold & heat exposure

  • cold exposure as mild hormetic stress, not fat-loss magic
  • short cold showers over extreme ice rituals
  • sauna for relaxation, cardiovascular support, sleep quality
  • recovery prioritized over suffering

fat loss (honest framing)

  • fat loss requires a sustained energy deficit
  • exercise supports fat loss, diet adherence matters more
  • muscle preservation is the priority while cutting

extended fasting (strategic use only)

  • extended fasting can reduce fat mass and improve insulin sensitivity
  • higher risk, higher reward tool
  • not required for most people

who it may suit

  • metabolically unhealthy individuals
  • people with significant fat to lose
  • those with prior fasting experience

who should avoid

  • underweight individuals
  • eating disorder history
  • high training volume athletes
  • poor sleep or high stress baselines

protocol basics

  • typically 36–72 hours, not weeks
  • water intake is mandatory
  • activity volume reduced significantly
  • heavy lifting paused

supplements & electrolytes during extended fasting

  • sodium: prevents dizziness and low blood pressure
  • potassium: supports nerve and muscle function
  • magnesium: reduces cramps, supports sleep and stress
  • electrolytes must be sugar-free

optional

  • black coffee or plain tea (cautiously)
  • bone broth (technically breaks fast but improves safety)

rules

  • do not stack extended fasting with intense training
  • fasting days: walking or light zone 2 only
  • fed days: lift heavy, train hard

supplements (minimalist, focused list)

core vitamins

  • vitamin d: immune, mood, bone health
  • vitamin b12: nerve function, energy metabolism
  • folate (b9): cell division, neurological health
  • vitamin c: antioxidant, collagen synthesis
  • vitamin a (food preferred): vision, immune health
  • vitamin e: antioxidant support
  • vitamin k2: calcium regulation, bone and vascular health

minerals

  • magnesium (glycinate or threonate): sleep, stress, muscle relaxation
  • zinc: immune and hormone function
  • iron: oxygen transport (supplement only if deficient)
  • iodine: thyroid support
  • selenium: thyroid enzymes, antioxidant systems
  • potassium: electrolyte balance (prefer food sources)

fatty acids

  • omega-3s (epa/dha): cardiovascular, brain, inflammation balance

protein & amino acids

  • adequate dietary protein first
  • protein powders for convenience only
  • creatine monohydrate: strength, cognition, aging support
  • glycine: sleep quality, connective tissue support

gut support

  • fiber from food first
  • probiotics short-term, strain-specific
  • prebiotics to support existing microbiome

rules

  • food first, supplements last
  • test when possible, guess less
  • avoid stacking dozens of compounds

mental performance

  • attention is a finite resource
  • single-tasking beats productivity hacks
  • deep work protected by environment design
  • digital minimalism as cognitive hygiene

environment

  • reduce constant noise and notification load
  • clean air and ventilation matter more than gadgets
  • daylight exposure at workspaces
  • ergonomic basics over expensive setups

tracking & wearables

  • tools for pattern recognition, not self-surveillance
  • trends > daily fluctuations
  • sleep regularity > sleep scores
  • stop tracking if it increases anxiety

what fades

  • extreme fasting as a lifestyle
  • biohacking as identity or flex
  • optimization without trade-off awareness
  • novelty chasing

what wins

  • boring routines done daily
  • recovery as performance
  • muscle + heart + mitochondria as priorities
  • sustainability over intensity

bottom line

the best biohack is not adding more

it is removing friction, noise, and self-inflicted stress

lift weights, protect sleep, move daily, recover hard

consistency beats sophistication every time
