Foundations

Longevity vs healthspan: what matters

• Disease avoidance: Lower the risk and delay the onset of the big four: atherosclerotic cardiovascular disease (ASCVD), cancer, metabolic disease, and neurodegenerative disorders.
• Functional capacity: Preserve strength, aerobic fitness, balance, mobility, and cognitive reserve so that everyday tasks remain easy.
• Emotional and social vitality: Maintain purpose, connection, stress tolerance, and healthy sleep—foundations of decision-making and adherence.

1. Novelty chasing: Swapping fundamentals for supplements or unproven tech wastes time and attention.
2. Perfection paralysis: Waiting for an ideal plan delays easy wins you could capture this month.

• Write one sentence that defines your personal “why” for longevity. Keep it visible.
• Choose one outcome that matters most right now (e.g., “climb stairs without breathlessness,” “lower LDL-C by 30%,” “sleep through the night”).
• Commit to a four-week sprint focused on that outcome; measure before and after.

The longevity levers that compound

1. Pick one lever to upgrade first (often sleep or movement).
2. Define the input metric: e.g., “in bed 7.5–8.5 hours, lights out by 23:00.”
3. Pair a cue with a ritual: e.g., place walking shoes by the door; pre-log workouts.
4. Add friction to misaligned choices: e.g., keep ultraprocessed snacks out of the house.

• Two 45–60-minute strength sessions (push, pull, hinge, squat, carry).
• Two 30–45-minute zone-2 sessions plus 6–8 short intervals once.
• 7,000–10,000 steps most days.
• Protein at each meal; pre-sleep snack only if it improves your night.
• Ten-minute wind-down: lights dim, devices out.

Start with a baseline: know your numbers

• Family history of premature ASCVD, colorectal or breast cancer, type 2 diabetes, dementia.
• Current medications, supplements, alcohol pattern, and sleep quality.
• Injuries, surgeries, and movement limitations.
• Red-flag symptoms: chest pain with exertion, unexplained weight loss, blood in stool, new severe headaches—address these with a clinician before training hard.

• Resting heart rate, blood pressure (home average over several days), waist circumference, body weight trend.
• Functional markers: a comfortable 30-minute walk pace, ability to sit to stand without hands, single-leg balance for 10–20 seconds, and grip strength (if you have a dynamometer).

• Lipid panel with apoB (or LDL-C if apoB is unavailable).
• HbA1c and fasting glucose; consider fasting insulin or an oral glucose challenge if indicated.
• Basic metabolic panel, liver enzymes, and TSH if symptoms suggest.
• For specific ages/risks: colon cancer screening, cervical and breast screening per guidelines, and CAC scoring to refine ASCVD risk (when appropriate).

• Step count and sleep duration/regularity are useful; treat all device outputs as estimates, not diagnoses. Trends matter more than single points.

• If blood pressure averages ≥130/80 mmHg, pair diet tweaks (sodium awareness, potassium-rich foods) with movement and stress skills; consult on medication thresholds.
• If apoB is high for your risk category, prioritize diet composition, weight targets, and discuss pharmacotherapy when indicated.
• If sleep is fragmented, fix schedule, light, and caffeine minimums before adding training volume.

• Ordering broad panels with no plan to act.
• Chasing tiny changes that live within normal biological variation.
• Ignoring symptoms while “waiting for labs.”

From biomarkers to outcomes: reading signals

1. Hard outcomes: myocardial infarction, stroke, fracture, cancer incidence, disability.
2. Validated risk scores or imaging: coronary artery calcium (when appropriate), ASCVD risk calculators.
3. Causal or strongly associated biomarkers: apoB, blood pressure.
4. Context-sensitive markers: fasting insulin, CRP, HRV.
5. Behavioral proxies: steps, sleep stages (device-estimated).

• HRV obsession: Useful for load management, but day-to-day swings are not health verdicts. Make changes based on stable trends and symptoms.
• Glucose micromanagement in low-risk people: Post-meal variability exists; focus first on long-term glycemic control, fiber, protein timing, and overall diet quality.
• Unvalidated panels: If a test is not tied to actionable thresholds, do not let it steer your plan.

• apoB high? Emphasize dietary pattern shifts (more viscous fiber, replace saturated fats with unsaturated fats), weight targets, and discuss medication if risk warrants.
• BP elevated? Salt awareness, aerobic volume, stress skills, and consider pharmacotherapy per guidelines.
• VO₂ max low? Add zone-2 minutes and progressive intervals; retest with a standard protocol.
• Bone risk? Strength training with progressive loads, adequate calcium and vitamin D intake, and fall-prevention drills; screening where indicated.

• Rank your top five biomarkers by relevance to your goals.
• Set action thresholds and re-test intervals now, before you see the next result.
• Create a one-page “If X, then Y” response map.

Behavior change that sticks: tiny steps

• Choose an action that takes ≤2 minutes to begin (fill a water bottle; put on shoes; set a 10-minute timer).
• Attach it to a stable cue (after I brush teeth, I lay out gym clothes).
• Close with a quick reward (checkmark, brief breath of pride, playlist).
• After two weeks of 90% compliance, scale duration or difficulty by 10–20%.

• Reduce steps for good choices (pre-cut veg, pre-logged meals, gym bag in car).
• Increase friction for misaligned choices (unplug streaming device on weeknights; keep dessert out of the house).
• Decide once for the week: put workouts and meal anchors on the calendar.

• Minimums: 10-minute walks, 1 set of each main lift, lights out by 23:00.
• Scripts: “When I scroll past bedtime, I plug the phone in the kitchen.”
• Forgiveness window: resume the next meal or next day; do not “compensate” with extremes.

• Use weekly reviews: What worked? What felt hard? What will I change?
• Track 1–3 leading indicators (sleep time, steps, workouts completed) and 1–2 lagging indicators (waist, BP, apoB).
• Celebrate adherence, not only outcomes; outcomes lag.

1. Put two strength sessions on your calendar.
2. Walk 10 minutes after two meals on three days.
3. Set “bed ready” at 22:30 with lights low.
4. Eat protein with breakfast and lunch.
5. Record your bedtime, steps, and sessions.
6. Review on Sunday: keep, cut, or tweak one thing.

Sequencing your plan without overwhelm

• Fix your sleep window and anchor wake time.
• Place two strength sessions and two aerobic sessions on recurring days.
• Add two evening wind-down cues (dim lights, device off). Why first? Sleep boosts adherence, recovery, mood, and appetite control; regular training slots reduce decision fatigue.

• Progress strength with simple linear increments (e.g., add 2.5–5 kg when you hit target reps).
• Accumulate zone-2 minutes; add one short interval session per week once base is steady.
• Keep daily steps high to reinforce NEAT (non-exercise activity thermogenesis).

• Hit protein and fiber minimums; set a calorie target if fat loss or gain is a goal.
• Use meal templates (protein + veg + smart carb + healthy fat) and plan two batch-cook staples.
• Introduce time-restricted consistency, not aggressive fasting; prioritize quality over window.

• Recheck BP, weight trend, waist, and subjective energy monthly; labs at 3–6 months if changing treatment.
• If progress stalls, tweak the lever most responsible (e.g., increase zone-2 volume for CRF; adjust dietary fats and fiber for lipids).

• One lever up, one lever steady: When you increase training intensity, keep nutrition changes simple; when you start a new diet phase, keep training stable.
• Guardrails: Define hard stops (e.g., no workouts past 21:00, no “catch-up” intervals after poor sleep).
• Recovery weeks: Every 4–8 weeks, plan a deload—lighter loads, more sleep, extra walks.

• Add a third strength day to break plateaus.
• Use a CGM for a time-boxed learning period if you are adjusting nutrition with a clinician and have clear questions.
• Explore supplements with proven benefits for your specific risk profile; keep the list short.

• Review last week’s adherence and any red flags (sleep debt, soreness, irritability).
• Plan exactly when and where you will train and shop.
• Pre-decide two “pressure valves” for busy days (10-minute minimal workout; prepared protein in the fridge).
• Write one “not this week” boundary to protect sleep and training.

Design your environment for easy wins

• Put protein and produce at eye level in the fridge; move desserts and ultraprocessed snacks to opaque bins or out of the house.
• Prepare grab-and-go options on Sundays: boiled eggs, roasted chicken, chopped veg, lentil salad, pre-portioned nuts.
• Keep a “assemble, don’t cook” shelf (tinned fish, microwaveable grains, olive oil, frozen veg) for 10-minute dinners that beat takeout.

• Treat your bedroom like an analog zone: dark, quiet, cool (16–19°C), with phone charging outside.
• Use a wind-down cue: when you dim lights at 22:00, switch to paper reading or a short stretch.
• If noise/light is unavoidable, standardize sleep kit: blackout curtains, eye mask, and earplugs.

• Place a kettlebell or dumbbells in a high-traffic area; pair kettle boils with 10–20 reps.
• Use a walking workspace strategy: after calls, do a 5-minute hallway loop; schedule walking one-on-ones.
• Keep shoes by the door and a packed gym bag in your car trunk to shrink the time from intention to action.

• Set app limits during your sleep wind-down; log out of most distracting apps.
• Move entertainment to weekend blocks; put a sticky note on the remote that reads “lights out by 23:00.”

• Recruit a workout partner or small group; social obligations dramatically increase adherence.
• Plan ritual meals—a weekly family dinner or Sunday batch-cook—so nutrition and connection reinforce each other.
• Choose venues that fit your plan (cafés with protein options, restaurants where vegetables are normal, not special).

• Shop your list, not the aisle. Never buy “sometimes” foods by default.
• Workout on calendar = meeting. No rescheduling more than once.
• No screens in bed. If you need a device for reading, use airplane mode.

1. Remove one friction point per room (bedroom, kitchen, living area).
2. Add one cue for movement at home and one at work.
3. Script two social touchpoints that promote healthy defaults (walk with a friend; cook together).

Integrating the week: sleep, stress, movement, food

• Monday: Strength A (push, squat, carry) + early bedtime.
• Tuesday: Zone-2 30–45 minutes + 10-minute breath practice.
• Wednesday: Strength B (pull, hinge, lunge) + evening stretch.
• Thursday: Walk meetings + optional short intervals (6 × 1 minute).
• Friday: Recovery emphasis (steps, mobility) + social dinner with a protein-first plate.
• Saturday: Long walk or hike + batch-cook staples.
• Sunday: Review last week, plan next, lights low by 22:00.

• Sleep anchors: fixed wake time, wind-down cue at the same clock time, and morning light within 60 minutes.
• Meal anchors: protein + plants at breakfast and lunch; evening plate built around veg volume.
• Stress anchors: short, repeatable drills—6 slow breaths before meetings; 5–10 minutes of mindfulness after work; a “closing ritual” to end the day.

• If sleep drops below 6.5–7 hours or you wake unrefreshed for two nights, swap intensity for volume: zone-2 instead of intervals, technique work instead of heavy sets.
• Use RPE (rate of perceived exertion) to self-titrate: aim 6–8/10 on work sets, 3–4/10 for zone-2.
• Preserve steps on off days; low-intensity movement speeds recovery.

• Breakfast: Greek yogurt or tofu + berries + nuts; or eggs + greens + whole grain toast.
• Lunch: protein bowl (beans/chicken/fish) + big salad + olive oil; or leftovers.
• Dinner: sheet-pan veg + salmon/chicken/tempeh + grains or potatoes.
• Snacks: fruit, nuts, cottage cheese; avoid grazing after dinner.

1. Stacking all the difficulty at once (hard intervals + new diet + late work) → plan a hard-easy flow.
2. Weekend whiplash: social events derail sleep and meals. Pre-decide where you will hold the line (sleep window, protein at each meal) and where you will flex (dessert, drink count).

• Put strength and cardio sessions on the calendar with times and locations.
• Inventory fridge and write a short list for two staples and two vegetables.
• Block 10-minute recovery windows on heavy days.
• Note one joy event (friend call, family walk) to sustain momentum.

Risk stratification: red flags to act on

• Chest pain or pressure with exertion, unexplained shortness of breath, or fainting.
• Neurological deficits (sudden weakness, speech trouble, face droop).
• GI bleeding (black or bloody stools), persistent unexplained weight loss, or severe new headaches.
• Signs of infection with high fever and confusion.

• Family history of premature ASCVD (men <55, women <65), hereditary cancers, or early-onset dementia.
• Long-standing hypertension, diabetes, smoking, or autoimmune disease—all change training and nutrition priorities.
• Falls or fractures after minimal trauma—consider bone health workup and strength balance training.

• ASCVD risk calculators to inform lipid management and blood pressure thresholds.
• Coronary artery calcium (CAC) scoring to reclassify intermediate risk (when appropriate).
• Age- and risk-based cancer screening: colon, breast, cervical, and—for heavy smokers—lung.
• Bone density testing in at-risk groups; consider earlier evaluation for those with fractures or high risk medications.

• If you have uncontrolled hypertension, avoid heavy isometrics until BP is treated and stable; emphasize aerobic base and medication adherence.
• With diabetes or reactive hypoglycemia, place carb intake around activity and carry a rapid glucose source during longer sessions.
• For joint pain or osteoarthritis, favor progressive resistance with joint-friendly ranges, daily steps, and cycling or pool work rather than high-impact intervals.

• High apoB or strong family history? Prioritize diet quality, weight targets if indicated, and clinician-guided lipid therapy.
• Elevated BP? Make sodium awareness, aerobic minutes, and stress skills non-negotiable while you and your clinician calibrate medications.
• Low bone density? Emphasize lifting with progressive load, impact where tolerated, fall-proofing, calcium and vitamin D intake, and medical therapy when appropriate.

• Which symptoms or history items above apply to you?
• Are your screenings up to date for age and risk?
• What is the one action you will take this week to reduce risk (book an appointment, check home BP, schedule a colon screening)?

N of 1 experiments: make decisions with data

1. Question: Example—“Does a 30-minute evening walk improve my sleep continuity?”
2. Outcome metric: Choose the simplest reliable measure: wake after sleep onset, nightly wake count, or subjective sleep quality (1–5) captured each morning.
3. Protocol: Alternate A/B weeks (walk vs no walk) or use a simple ABA design (baseline → walk → baseline). Keep everything else stable.
4. Decision rule: Define success before you start (e.g., “average wake time decreases ≥15 minutes for at least 5 of 7 nights”).

• Track inputs (did I walk?), contexts (bedtime, caffeine/alcohol), and the single primary outcome.
• Ignore noisy secondary metrics (daily HRV swings) unless they are part of your decision rule.
• Average results across the test period; look for magnitude, not perfection.

• Nutrition: Compare two breakfast patterns (higher protein vs higher carbohydrate) and assess hunger, energy, and glycemic responses.
• Training: Test whether adding one interval session improves 5K time after four weeks.
• Sleep: Evaluate a cooler bedroom or earlier wind-down.
• Stress: Trial a 10-minute breath protocol vs a short yoga flow for afternoon calm.

• Keep the change small and the period short (2–4 weeks) so you finish.
• Pre-register your rule in your notes.
• If possible, blind supplements (two identical jars prepared by a friend; label revealed after).
• Use “minimal effective dose” thinking—if a small, simple change works, you have a winner.

• Do not self-experiment with prescription medications, unsafe doses, or contraindicated protocols without medical oversight.
• Respect washout periods for interventions with lingering effects.

• Question: Does a 10-minute post-dinner walk improve my fasting glucose and sleep quality?
• Protocol: 7 days baseline, 7 days walking; fixed bedtime and caffeine cut-off.
• Measures: Morning glucose (home meter if appropriate), sleep quality score (1–5).
• Decision: Keep the walk if fasting glucose improves by ≥5 mg/dL or sleep score improves ≥1 point on ≥4 of 7 days.

Sex and age differences: tailor the approach

• Premenopausal: Iron status matters (especially with heavy menses). Strength training builds peak bone mass and protects pelvic and knee health.
• Pregnancy and postpartum: Focus on safe activity (as cleared by clinicians), pelvic floor support, and sleep conservation; nutrition emphasizes protein, fiber, calcium, and choline-rich foods.
• Perimenopause: Expect sleep variability, thermoregulation changes, and shifts in body composition. Double down on progressive resistance (2–3 days/week), protein adequacy (~1.6 g/kg/day as a useful upper target for many), and consistent bedtime. Discuss symptom management, including hormone therapy suitability, with your clinician.
• Postmenopause: Bone health and metabolic risk become central—lift progressively, include impact where tolerated, and ensure calcium and vitamin D intake; update ASCVD risk with current labs.

• 30s–40s: Strength and VO₂ max can slip quietly with sedentary work—program two serious strength days and aerobic base work now.
• 50s–60s+: Watch central adiposity and rising BP; keep heavy lifting but mind joint management and recovery windows. Screen for sleep apnea if snoring plus daytime sleepiness.

• 40s: Preserve VO₂ max and set strength baselines (5RM compound lifts or bodyweight equivalents).
• 50s: Double down on blood pressure and lipids, add balance drills, and keep intervals modest but regular.
• 60s+: Train power (lighter loads, faster intent), practice getting up and down from the floor, and prioritize fall prevention.

• Some medications (beta-blockers, antihistamines, certain antidepressants) influence HR, sleep, or weight—coordinate training plans with your clinician.
• Recovery windows often lengthen with age: bias quality over volume; schedule more easy aerobic minutes and mobility.

• Align your training with screening (colonoscopy, mammography, bone density) so recovery is baked in.
• Ask about vaccine schedules relevant to your travel and age.

• What life stage are you in, and which two risks feel most salient (bone, BP, sleep, weight, strength)?
• Which lever (strength, zone-2, protein, sleep regularity) will you emphasize this month to match that stage?

Sustainability and relapse prevention: systems that stick

• Use a weekly scoreboard with three checkboxes: strength sessions, aerobic minutes, sleep window.
• Track inputs, not only outcomes. Outcomes lag; inputs teach you what to repeat.

• Travel: Pack resistance bands; identify a hotel routine (push, hinge, carry patterns) and a 10-minute fallback workout. Pre-plan two protein-first meals per day.
• Busy season: Switch to maintenance programming—two total-body lifts, short daily walks, strict sleep window.
• Illness or injury: Follow return-to-play rules—start at 50–70% of usual volume, rebuild in 10–20% steps, and bias zone-2 and mobility.

• After missed workouts: “I’m not behind; I’m resuming the plan at the next scheduled session.”
• After overeating: “Next meal is back to template; no compensation fasts or punishment intervals.”
• After poor sleep: “Protect tonight’s wind-down; choose zone-2 over intervals today.”

• Rotate movement cycles every 6–8 weeks (new rep schemes or exercise variations).
• Try a recipe theme week (legumes, sheet pans, grill).
• Set skill goals (single-leg balance for 30 seconds, push-up or pull-up progressions).

• Pair goals with people—walking clubs, lifting groups, cooking nights.
• Revisit your why quarterly; update it when life changes. Meaning and connection protect adherence more than hacks.

1. Re-scan risks: BP, waist, symptoms, and any labs due.
2. Evaluate your rhythm: what felt easy, what felt brittle?
3. Choose one upgrade and one simplification for the next 12 weeks.
4. Plan one joy event that nourishes relationships.
