Advanced Longevity Plan (Biohacker)
GPT-5-nano'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
Below is a dense, action-ready 12-week plan designed for a biohacker aiming to optimize longevity, physical and cognitive performance. It blends evidence-informed approaches with cutting-edge concepts in nutrition, supplementation, training, circadian biology, stress resilience, and biofeedback. This is intended as a framework you can customize with your clinician, equipment, and personal response. Do not start any new supplement or aggressive fasting/ketogenic protocol if you have medical conditions, are pregnant, or take prescription medications without medical supervision.
Core principles
- Personalize from wearables & labs; progressive overload with recovery; use CKD/TKD as needed; sleep and circadian first; stress regulation via HRV
What to track
- Sleep duration/efficiency; HRV RMSSD trend; RHR; glycemic responses (CGM if available); training load; mood/focus
Phase 0 (prep)
- Fix schedule; establish baselines; confirm macro starting point; list supplements and begin with one change at a time
Phase 1 (Weeks 1–4) — Foundation
- Diet: low-carb baseline (20–50 g net) with TRF 14:10 → 16:8; protein 1.6–2.2 g/kg/day; electrolytes
- Training: strength 3x/wk; Zone 2 2–3x/wk; HIIT 1x/wk; mobility daily
- Supplements: creatine 5 g; omega‑3 (EPA/DHA 1–2 g/d combined); vitamin D3 1–4k IU (+K2); magnesium 200–400 mg; glycine 3 g; optional taurine 1–2 g
- Cognitive stack (optional/cycled): rhodiola 200–400 mg AM; lion’s mane 500–1000 mg BID; bacopa 300 mg; citicoline 250–500 mg
- Sleep: cool, dark room; caffeine cutoff 8–10 h before bed; NSDR 10–20 min on hard days
Phase 2 (Weeks 5–8) — Build
- Switch to CKD or TKD for performance: refeed 100–250 g carbs 1–2 days/wk (CKD) or 20–40 g pre‑workout (TKD)
- Training: 3‑week build periodization; add 2nd weekly HIIT (4×4 + 30/30s);
- Consider: Urolithin A 500 mg; NR/NMN 250–500 mg (cycle); curcumin 500–1000 mg; berberine 500 mg pre‑carb meals on refeed days
- Recovery: sauna 2–4x/wk 15–30 min; cold 2–4x/wk 2–5 min; avoid cold 6–8 h post strength if hypertrophy goal
- Week 8 deload: 36‑h fast OR FMD if experienced/cleared; sleep ≥8 h
Phase 3 (Weeks 9–12) — Peak & consolidate
- Maintain strength intensity, trim volume; VO2 focus (2x/wk); Zone 2 1–2x/wk
- Keep CKD/TKD as suits performance; protein steady; adjust refeeds to recovery
- Test Week 12: 5RM estimates, VO2 test or 12‑min run, grip strength, sleep/HRV trends, CGM if used
Guardrails
- HRV down >15% or RHR up ≥7 bpm for 2–3 days → cut volume 30–40% and swap to Zone 2 for 48–72 h
- Sleep <6.5 h/efficiency <85% → pull intensity; earlier training; improve light hygiene
- CGM spikes >140 mg/dL or >30 mg/dL delta → adjust carbs/timing; add post‑meal walks
- Weight/mood dips → add calories on refeed days, ensure protein, manage stress and sleep
Targets by Week 12
- VO2max +5–15%; strength +5–15%; fat −3–6% (if needed) with lean mass preserved; HRV trend up; RHR down; hs‑CRP lower; fasting insulin <7 μIU/mL
Implementation
- Introduce changes gradually; journal sleep/HRV/mood/training; iterate at weeks 4, 8, 12; clinician oversight for any Rx steps.
