Longevity is an engineering problem.

Twenty years of optimizing elite humans, distilled into systems you can run. No hacks, no hype — the mechanics of a body that performs today and lasts decades. Every body is a system. Every system can be optimized.

Latest from the Library: VO2 Max — the single best predictor of how long you'll live · The Sunday Scan — why a weekly photo beats the scale

01 · Nutrition

The Protein Intelligence System

Most people don’t have a diet problem. They have a protein-distribution problem. They eat 60% of their protein at dinner, almost none at breakfast, and then wonder why they can’t hold muscle in a deficit or wake up hungry at 11pm.

The targets

For body recomposition and healthy aging, the working range is roughly 0.8–1 gram of protein per pound of goal body weight per day. Aging bodies are less sensitive to the muscle-building signal from protein — which means the target goes up as you get older, not down. Muscle is the organ of longevity: it’s your glucose sink, your fall insurance, and your metabolic engine.

Distribution beats totals

Split that total across 3–4 feedings of 30–50 grams. The first one matters most: 30+ grams of protein before noon stabilizes appetite, blood sugar, and energy for the entire day. If you consistently miss it, you will consistently overeat at night. That single pattern explains more stalled progress than any supplement ever will.

Protein at breakfast is a decision. Everything after it is momentum.

Make it boring

Elite nutrition is repetitive by design. Pick three protein-forward breakfasts, three lunches, three dinners you actually enjoy, and rotate. Novelty is for restaurants; progress runs on defaults.

02 · Training

Training for the Decades, Not the Mirror

The mirror rewards the next eight weeks. Longevity rewards the next forty years. The good news: the same two inputs drive both — strength and cardiorespiratory fitness. VO2 max and muscle strength are among the strongest predictors of how long and how well you live.

The weekly skeleton

Three to four strength sessions built around the patterns your life depends on: squat, hinge, push, pull, carry. Add two to three hours of easy “zone 2” cardio — conversational pace, nasal breathing — and one short session that pushes near max effort. That’s the whole prescription. Everything else is seasoning.

Tension is the language

Muscles respond to mechanical tension, not to exhaustion. Control the lowering phase, own the stretch position, stop one or two reps before failure most sets. Grip width, tempo, and range of motion are targeting tools — small adjustments redirect the stimulus better than new exercises do.

You don’t stop training because you get old. You get old because you stop training.

Progress you can audit

Log the numbers. Strength going up over months while bodyweight holds or drifts down is recomposition working. If two bad sleep nights stack up, cut volume 30% and keep intensity — showing up smaller beats not showing up.

03 · Recovery

Sleep Is Your Master Recovery Protocol

Every optimization you care about — body composition, decision-making, mood, hormonal health, training output — runs through sleep first. It is the highest-leverage 8 hours of your life, and most people negotiate it away nightly.

The non-negotiables

A consistent wake time, seven days a week, is the anchor — your circadian rhythm calibrates to when you get up, not when you lie down. Morning outdoor light within an hour of waking sets the clock. Caffeine has a quarter-life of ~12 hours: an afternoon double espresso is still a quarter-espresso at midnight. Cut it 8–10 hours before bed.

The bedroom is a system

Cold (65–68°F), dark enough that you can’t see your hand, and boring. The bed is for sleep — the moment it becomes a second office or a scrolling station, your brain stops associating it with shutting down.

Ninety extra minutes of sleep will out-perform any recovery gadget you can buy.

When sleep breaks anyway

Travel, kids, launches — life happens. The protocol after a bad night: same wake time, morning light, train lighter, protein-anchor your meals, and refuse the 9pm rescue-nap that steals tomorrow’s sleep too. One bad night costs little; the spiral costs everything.

04 · Data

Biomarkers: Reading Your Own Dashboard

You wouldn’t run a company without a P&L. Your body publishes one — most people just never read it. A basic annual blood panel, tracked over years, tells you whether your system is trending toward performance or toward disease long before symptoms show up.

The panels that matter first

Metabolic health: fasting glucose, HbA1c, fasting insulin. Cardiovascular: a full lipid panel — and ask about ApoB, the particle count that predicts risk better than LDL alone. Inflammation: hs-CRP. Hormonal and micronutrient basics: thyroid, vitamin D, ferritin. None of these are exotic; all of them are actionable with training, nutrition, and sleep.

Trends beat snapshots

A single reading is weather. Three readings a year apart are climate. Keep your results, chart the direction, and treat every intervention — diet change, training block, stress season — as an experiment whose results show up in the next draw.

Optimal is not the same as “normal range.” Normal is the average of a population that is mostly unwell.

Education, not diagnosis: lab interpretation belongs in partnership with your clinician. What you bring to that conversation — years of your own trend lines — is what turns a 12-minute appointment into a real strategy session.

05 · Body Composition

Body Recomposition Without the Crash

Crash diets work — for eight weeks. Then biology collects: hunger hormones surge, output quietly drops, muscle goes with the fat, and the rebound erases the summer. Recomposition — losing fat while holding or building muscle — is slower and permanent.

The physics, honestly

A moderate deficit of 300–500 calories, protein at 1g per pound of goal weight, and three-plus strength sessions a week. That combination tells your body precisely what to burn (stored fat) and what to keep (muscle). Bigger deficits don’t send a louder message — they send the wrong one.

Judge trends, not days

The scale lies daily and tells the truth weekly. Water, sodium, glycogen, and stress can swing daily weight by several pounds in either direction. Weigh daily if you like, but decide weekly: the 7-day average, waist measurement, progress photos, and strength numbers are the real scoreboard.

Aim to lose 0.5–1% of bodyweight per week. Slower than your ego wants. Faster than any approach you’ll actually keep.

The last five pounds

Plateaus are data, not failure. Two flat weeks means the deficit closed — your smaller body burns less. Nudge activity up (walking is the cheapest lever in the system), tighten weekend tracking, and keep going. The people with the “after” photos are simply the ones who didn’t stop.

06 · The Meta-System

The Consistency Engine

The best protocol you’ll ever run is the one that survives your worst week. Motivation is a spark; systems are the engine. Elite performers don’t rely on wanting to — they build defaults where the right action is the easy action.

Shrink the decision

Same training days, same time, bag packed the night before. Groceries on the same day, same core list. Protein-forward defaults at every meal. Every decision you remove is willpower you bank for the days that actually test you.

The 80% rule

Perfect weeks are rare; good weeks are repeatable. Hitting your training, protein, sleep, and steps at 80% for a year will transform you more than hitting 100% for six weeks and vanishing for six months. Consistency compounds; intensity impresses.

Never miss twice. One missed workout is life. Two is the start of a new identity.

Measure the streak, not the mood

Track the behaviors you control — sessions completed, protein days, sleep hours, weekly scans — and let outcomes follow. A visible streak is the most underrated performance technology in existence: it converts identity (“I’m someone who trains”) into evidence.
