Advanced Longevity Plan (Biohacker)
GPT-5's response to the 'Advanced Longevity Plan (Biohacker)' challenge.
?Prompt
Develop a comprehensive, cutting-edge 3-month longevity plan for a biohacker aiming to optimize longevity, physical and cognitive performance. Incorporate advanced strategies like specific supplement stacks (with dosages and cycling), detailed dietary protocols (e.g., ketogenic variations, fasting regimens), advanced wearable tracking, personalized exercise routines (including strength, HIIT, and recovery), stress resilience techniques (e.g., HRV training, neurofeedback concepts), among other things. The plan should be highly detailed and actionable.
Response
Important note: The following is an intensive, experimental plan intended for healthy adults with physician oversight. It is not medical advice. Discuss all supplements, fasting, heat/cold exposure, and any prescription considerations with your clinician, especially if you have cardiovascular, metabolic, thyroid, psychiatric, or kidney/liver conditions, are on medication, or have a history of eating disorders. Stop or scale back if you experience red flags (dizziness, chest pain, fainting, persistent fatigue, sleep disruption).
Objective
- Maximize healthspan, physical and cognitive performance over 12 weeks, while building sustainable habits and measurable improvements in:
- VO2max, strength, muscle mass, body fat, glycemic control, HRV, sleep quality, inflammation (hs-CRP), and subjective wellbeing.
- Approach: phased training, cyclical ketogenic nutrition with strategic refeeds, targeted supplementation with cycling, hormetic stress (heat/cold) with recovery, HRV/neurofeedback-based stress regulation, and dense biomonitoring.
Week 0 (Setup and Baseline)
- Baseline testing
- Labs (fasting): apoB, lipid panel + Lp(a), CMP, CBC, hs-CRP, fasting glucose/insulin (HOMA-IR), HbA1c, uric acid, TSH+free T3/T4, ferritin/iron/TIBC, B12, folate, 25(OH)D, IGF-1, morning cortisol, testosterone/estradiol/SHBG (or DHEA-S), creatinine/eGFR, ALT/AST, urine albumin/creatinine. Optional: omega-3 index.
- Body comp and fitness: DEXA, resting BP, resting HR, grip strength, 1RM estimates (or 5RM) for squat/press/deadlift, VO2max estimate (Cooper test or wearables), 5-minute HRV baseline (supine, same time daily x5 days), sit-to-stand test, 1-minute push-ups, 1-minute sit-ups, 10-m gait speed.
- Cognitive baseline: simple reaction time (e.g., HumanBenchmark), N-back accuracy, Stroop task, Psychomotor Vigilance Task (PVT) app.
- Gut: note GI symptoms; consider 3-day food symptom log.
- Gear and apps
- Wearables: Oura or Whoop (sleep/HRV), Apple Watch or Garmin (workouts/VO2), optional CGM for 4 weeks (Levels/Nutrisense), blood pressure monitor (AM/PM), blood glucose/ketone meter (Keto Mojo), breath ketone (optional Biosense).
- Software: Cronometer (macro/micro tracking), TrainingPeaks or TrainerRoad (programming), HRV4Training or Elite HRV (morning HRV), HeartMath or Breathwrk (biofeedback), MUSE S or FocusCalm (consumer neurofeedback), Notion/Google Sheet for dashboard.
- Environment: bedroom 17–19 C; blackout curtains; 10,000 lux lamp for mornings; blue-light filters; HEPA air purifier; water filter.
- Targets and rules
- Body composition: protein 1.6–2.2 g/kg/day; body fat reduction if needed 0.3–0.7%/week.
- Activity floor: 8,000–12,000 steps/day; 3–5x/week sauna or hot bath; 2–4x/week cold exposure (timing away from strength days).
- HRV-based autoregulation: if 3-day rolling HRV drops >15% from personal baseline and RHR +5–7 bpm, reduce intensity/volume 30–50% for 48–72 hours.
- Post-meal glucose: aim <140 mg/dL peak, back to baseline within 3 hours; adjust carbs and order of eating accordingly.
Nutrition: cyclical ketogenic with strategic refeeds
- Default (Mon–Fri): low-carb ketogenic
- Protein: 1.8–2.2 g/kg/day (prioritize lean, collagen-rich cuts + fish).
- Net carbs: 20–50 g/day from non-starchy veg and berries.
- Fat: to satiety (mostly mono/polyunsaturated, olive oil, avocado, nuts; include omega-3 fish).
- Fiber: 30–50 g/day from non-starchy veg, chia/flax, psyllium if needed.
- Electrolytes: sodium 4–6 g/day total (food + electrolytes), potassium 3–4.7 g/day, magnesium 300–400 mg/day from food/supp.
- Refeeds (Sat, optional Wed): 1–2 days/week higher carb to support thyroid, hormones, performance
- Carbs: 2–3 g/kg/day from low-processed sources (potatoes, rice, oats, fruit), start meal with protein/veg, limit fat those days.
- Place refeeds around heaviest strength/HIIT days.
- Meal timing
- Most days: 16:8 time-restricted eating. Feed window noon–8 pm. Protein-forward first meal.
- One 24-hour fast each week (e.g., dinner-to-dinner), skipped during deload weeks or if under-recovered.
- Optional (with medical oversight): One 36-hour fast in Week 8 OR a 4–5 day fasting-mimicking diet (FMD) substitute; choose one, not both.
- Supplements to support keto transition: adequate sodium, magnesium; consider MCT oil 5–10 mL to ease early weeks.
Core supplement stack and cycling Note: Verify interactions (e.g., SSRIs, thyroid meds, anticoagulants, antihypertensives). Start one new item every 3–4 days to assess tolerance.
Daily foundation (generally continuous for 12 weeks)

- CO2 tolerance: weekly BOLT test.
- Neurofeedback (consumer EEG): 10–20 min/day, 4–5 days/week. Alpha-up (Weeks 1–4), SMR/beta focus (Weeks 5–8), alternate in Weeks 9–12; stop 3–4 hours before bed.
- NSDR/Yoga Nidra: 10–20 min afternoons.
- Psychology: 3-minute gratitude nightly; daily 10-minute social connection.
Daily rhythm & sleep
- Morning outdoor light; dim evening light. Cool bedroom 17–19 C. Caffeine cutoff 8–10 hours before bed. 7.5–9 hours/night. Simple wind-down routine.
Nutrition tactics

- Hydration: 30–35 mL/kg/day; electrolytes as needed.
- Alcohol: ideally zero; ≤1 drink/week if any; avoid within 3 hours of bedtime.
Weekly outline (example)
- Mon: Upper + Z2 30–40; keto.
- Tue: Lower + mobility; sauna; keto.
- Wed: VO2 4×4 + plyos; refeed; HRV/coherence work.
- Thu: Upper (hypertrophy) + Z2; keto.
- Fri: Lower (heavy); sauna; keto or start 24h fast.
- Sat: Cold AM; Z2/ruck 60; refeed dinner.
- Sun: Recovery (yoga, mobility, NSDR); prep; alpha-up neurofeedback; keto.
Guardrails
- HRV down >15% or RHR up ≥7 bpm: swap to Z2, cut volume 30–40% for 48–72 h.
- Poor sleep: pull intensity; shift HIIT earlier.
- CGM spikes: adjust carbs, add post-meal walks.
- Weight/mood dips: raise calories/refeeds.
Targets after 12 weeks
- VO2max +5–15%; strength +5–15%; body fat −3–6% (if needed) with lean mass preserved; HRV trend +5–20%; RHR −3–7 bpm; hs-CRP toward <1 mg/L; fasting insulin <7 μIU/mL.
Contingencies
- Suspected thyroid slowdown: increase refeeds to 2×/week, carbs around training, check labs.
- Sleep issues on keto: add 20–40 g slow carbs at dinner; Mg + glycine; move HIIT earlier.
- Vegan/vegetarian: prioritize complete proteins; supplement creatine, B12, algal DHA/EPA; consider taurine.
- Joint issues: swap running HIIT for bike/row; collagen + vitamin C 60 min pre-session.
