The Longevity Protocol: A Realistic Daily Routine (2026)

By Trevor Kaak — Updated May 15, 2026

The longevity space in 2026 is a strange place. On one end you have Bryan Johnson, who spends $2M+ a year, takes 100+ pills a day, and films his own colonoscopy. On the other end you have a hundred Instagram coaches selling NMN powder and a "morning peptide stack."

In the middle is a small group of researchers and practitioners — Peter Attia, Rhonda Patrick, Eric Topol, Andrew Steele — who keep saying the same boring thing: exercise, sleep, protein, don't smoke, manage your ApoB, sauna a lot, lift heavy things, walk a lot, screen for cancer early.

The boring people are right. This is the routine that emerges when you take the actual evidence seriously and put aside the supplement-influencer noise.

I run this routine. I've tested most of what I left out. I've spent the money on the stuff I left in. Here's what survived four years of trying.

TL;DR — The Verdict Box

• The high-leverage interventions: Aerobic training (zone 2 + VO2 max work), strength training 3×/week, sleep (8 hours, consistent), protein (1.6–2.2g/kg), sauna 4+×/week, ApoB management, not smoking, social connection.
• The noise: NMN, NR, most "anti-aging" peptides, exotic supplement stacks, hydrogen water, grounding, sun-staring, fasting beyond 14 hours for most people.
• Why most longevity content is wrong: It optimizes for a number on a wearable instead of a 30-year time horizon. It sells supplements with non-human data. It ignores that the boring stuff (sleep, exercise, protein) does 90% of the work.
• The 80/20: If you sleep 8 hours, train 5×/week (mixing strength + cardio), eat enough protein, don't drink heavily, and get your ApoB down — you've captured almost the entire achievable longevity premium. Everything else is tinkering at the margins.
• What this article is and isn't: A practical protocol from someone who tests this stuff carefully. Not medical advice. Talk to a doctor before changing anything — especially if you take medication or have any cardiovascular history.

The Framework: What Are We Optimizing For?

There are three different things people mean when they say "longevity":

Lifespan

Years lived. The number on the gravestone. Important but blunt — dying at 92 in a wheelchair is not the goal.

Healthspan

Years lived in good function. Mobility, cognition, energy, independence. This is what most people actually want when they say "I want to live to 100."

Biomarkers

Surrogate measures we hope predict the above. ApoB, hs-CRP, fasting insulin, HbA1c, VO2 max, grip strength, deep sleep duration. None are the goal — they're indicators of the underlying biology.

My optimization target is healthspan. I want to ski with my grandkids, lift heavy at 75, and hike at 85. The biomarkers I track are the ones with the strongest evidence of being mechanistically linked to that outcome.

A wearable score tells me about today. A blood panel tells me about this quarter. The protocol below is about 30 years from now.

The Peter Attia "Four Horsemen" Framework

Attia's framing — that the four main causes of death after 40 are atherosclerotic disease, cancer, neurodegeneration, and metabolic dysfunction — is the most useful lens I've found for prioritizing this.

Notice the overlap. Exercise shows up in three. Sleep in two. ApoB and glucose control are essentially the same fight in different uniforms. The interventions that defend against multiple Horsemen are the highest-leverage ones.

Exercise is the most polypharmacy-replacing intervention on the list. If you train hard 5×/week, you're already attacking three of the four. Add a quarterly blood panel and a colonoscopy schedule and you've covered the fourth.

The Bryan Johnson Blueprint, Honestly Reviewed

I've watched Bryan Johnson's protocol evolve for three years. Here's the honest take.

What's worth copying

• Consistent early bedtime. Sleep window is non-negotiable for him. Good lesson.
• Strict food timing. Meals compressed into a roughly 8-hour window in the first half of the day. Reasonable for most people, though the rigid extremism isn't necessary.
• Heavy use of testing. Continuous biomarker tracking, regular imaging. The data discipline is genuinely useful.
• Plant-forward but protein-adequate. His stack hits protein targets, just not via meat.
• Resistance training, daily movement. Yep.

What's not worth copying

• The 100+ supplement stack. Most of it has no human longevity data. Some (high-dose rapamycin in particular) has real risk profile. The cost-benefit doesn't make sense for non-billionaires (or for most billionaires, frankly).
• Plasma exchange / blood swaps with his son. Not validated. Not recommended.
• Most of the "anti-aging" peptides. Underregulated, undertested, often imported from gray-market suppliers.
• The aesthetic theater. The skin protocols, the hair stuff, the eyebrow micro-pigmentation — fine if it's fun, irrelevant to lifespan.

The right takeaway

Bryan Johnson is running an N-of-1 experiment in extreme self-quantification. Some of what he's doing will eventually be validated. Some won't. Don't pay the maximalist price for the minimalist benefit. Run the basics first.

Pillar 1: Exercise

The single most important lever. Period.

Zone 2 cardio: 180–300 min/week

Conversational pace, ~70% max HR. Builds mitochondrial density, fat oxidation, lowers resting heart rate, raises HRV, protects the brain. The minimum effective dose is ~180 min/week; the curve keeps bending up to ~300.

I run ~250 min/week, split into 3–4 sessions on bike or rower.

VO2 max intervals: 1–2×/week

Norwegian 4×4 (4 min at 90–95% max HR, 3 min easy, repeat 4×). VO2 max is one of the strongest single biomarkers for all-cause mortality — top quartile vs bottom quartile is associated with 4–5× difference in mortality risk.

If you don't currently push to actual VO2 max work, this is probably your single highest-ROI training change.

Strength training: 3×/week

Compound lifts, full body or upper/lower split. Hypertrophy and strength both matter. After 40, the goal isn't to PR — it's to fight sarcopenia.

Grip strength, leg press, time to stand from the floor — these are the boring metrics that actually predict independence at 80.

Daily walking: 7,000–10,000 steps

Not optimization. Just basic ambulation. Has more independent mortality data than almost any other behavioral metric.

Pillar 2: Nutrition

The three things that matter, in order of impact:

1. Protein adequacy

1.6–2.2 g/kg/day. Particularly important after 40 when anabolic resistance kicks in. Hardest single nutritional rule for most people to hit consistently.

2. Fiber

30–40g/day from whole foods. Single best predictor of microbiome health, satiety, glucose control. Easier to hit than people think if you cook real food.

3. Caloric appropriateness for body composition

Not "be lean." Be the body composition that lets you train hard, sleep well, and not carry excess visceral fat. For most people that's a BMI 22–26 with reasonable muscle mass. Crash diets, aggressive fasts, and underfueling all backfire over decades.

What I deliberately don't worry about

• Macros beyond protein. Carbs and fats can flex. Eat the foods that let you train and recover.
• "Clean eating" purity. Whole-foods focus is fine, but stressing about every gram of seed oil is itself a stressor.
• Most "longevity diets." The Blue Zones data is observational and partially fabricated. The Mediterranean pattern has the best mortality evidence — but the underlying signal is mostly "vegetables, fish, olive oil, not sedentary, not isolated."

What I do

• High protein at every meal (35–50g)
• Vegetables at every meal (3+ cups)
• Whole-food starch when I've trained hard
• Olive oil as primary fat
• Fish 2–3×/week
• Limited alcohol (0–4 drinks/week)
• No deliberate fasting beyond 12-hour overnight

Pillar 3: Sleep

The non-negotiable.

The case for sleep as a longevity intervention is stronger than the case for any supplement on Earth, and almost as strong as the case for exercise. Insufficient sleep is associated with elevated all-cause mortality, increased dementia risk, impaired glucose control, suppressed immune function, and elevated CV risk.

The numbers I aim for

How I track

[Oura Ring 4](/sleep/oura-ring-4-review/) primary, Whoop 5 crosscheck quarterly. See the recovery wearable guide for the full comparison, Oura vs Whoop for the head-to-head, and Ultrahuman Ring Air for the subscription-free alternative.

The single biggest sleep upgrade

The [Eight Sleep Pod 4](/sleep/eight-sleep-pod-4-review/). Active cooling holds the bed at 62–65°F all night. My deep sleep duration jumped from ~1h12m to ~1h31m in the first two months. Expensive ($2,945 + $25/mo subscription) but it earns its place if sleep is your bottleneck.

Pillar 4: Stress + Recovery

Chronic stress is mechanistically tied to inflammation, glucose dysregulation, and cardiovascular disease. The interventions with the best evidence:

Sauna

The Finnish Kuopio data (Laukkanen et al.) on 4–7 sessions/week shows ~40% reduction in all-cause mortality vs 1 session, ~50% reduction in cardiovascular mortality, and reduced dementia incidence. The dose-response is real and the effect size is one of the largest in observational longevity literature.

My setup: Sun Home Solstice infrared, 4–5×/week, 20–30 min at 80°C / 176°F. See the home sauna guide for the buyer's matrix, Sunlighten mPulse for the high-end alternative, and Higher Dose blanket for portable/budget options.

Cold exposure

Smaller and more mixed longevity evidence than sauna, but solid effects on mood, dopamine regulation, brown fat activation, glucose tolerance. The Søberg metabolic data shows ~30% increases in cold-induced thermogenesis in trained-cold subjects.

My setup: Plunge Cold Tub, 3 min at 48°F daily-ish. See the cold plunge guide for the full primer, Ice Barrel and Plunge vs Ice Barrel for mid-tier options, DIY chest freezer for budget, and best cold plunge for cold climates if you live where it matters.

Contrast therapy

Sauna + cold protocol 1–2× a week. Combines both above.

Mindfulness / breath / NSDR

Lower evidence ceiling than the others, but the downside is zero and the consistency benefits compound. 10 minutes daily of any structured practice is enough.

Pillar 5: Supplements (Evidence Tier)

Let me sort this honestly.

Tier S: Take if you breathe

Things with strong evidence and effectively zero risk for healthy adults:

• Creatine monohydrate, 5g/day. Most-studied performance supplement, also has emerging cognition and bone density signals. ~$7/month. Best creatine for women for the female-specific data.
• Omega-3 (EPA+DHA), 2g/day. Strong cardiovascular and inflammation evidence, particularly if your omega-3 index is <8%. ~$25/month.
• Vitamin D3, dosed to blood level. Aim for 30–60 ng/mL. Most people are deficient. ~$3/month.

Tier A: Strong evidence for specific cases

• Magnesium glycinate, 400mg. Sleep, muscle, mostly safe. The form matters (glycinate or citrate, not oxide).
• Fiber supplement if you can't hit 30g+ from food.
• Electrolytes for athletes / sauna users.

Tier B: Plausibly useful, weaker evidence

• Glycine, 3g at night. Some sleep-quality data.
• Taurine, 2–3g. Promising mouse data; weaker human data.
• Curcumin. Anti-inflammatory; absorption is the gotcha.

Tier C: Hyped but I don't take

• NMN / NR. No human longevity data of consequence. My personal 9-month trial at 500mg NMN: no change in NAD+, no subjective effect. See the NAD supplement guide for what to do if you must.
• Resveratrol. The fish-oil-of-2010. Mostly debunked.
• Most peptide stacks. Underregulated, gray market, undertested.
• Hydrogen water. No.
• Most "anti-aging" branded blends. Pay for what you can name and dose.

Full deep-dive in the longevity supplement stack.

Pillar 6: Testing & Monitoring

You can't fix what you don't measure. And the most popular "biohacker" tests (DEXA, VO2 max) are useful but easier than the actually-important ones (ApoB, fasting insulin, hs-CRP).

My quarterly panel (via Function Health)

What I'd test before anything else

If you can only run three biomarkers: ApoB, fasting insulin, hs-CRP. Those three predict more about your cardiovascular and metabolic future than the next 30 markers combined.

Alternatives

• Function Health review — $499/yr for 100+ markers, my primary
• InsideTracker review — sport-targeted, with recommendations
• Best CGM for non-diabetics — 2 weeks/quarter for metabolic flexibility data
• Full overview: the at-home health testing guide

Imaging (not at home, but worth mentioning)

• Coronary calcium score: $100–$300, very high-value if you're over 40
• Full-body MRI (Prenuvo, Ezra): $2,500, false-positive rate is real but cancer-screening benefit can be real too
• DEXA scan: $50–$150, body comp + bone density

The Søberg Cold Dose for Metabolic Health

Susanna Søberg's research (Søberg et al., 2021) is the clearest dose-response data we have on cold exposure for metabolic outcomes.

The protocol:

• 11 minutes per week of cold exposure
• Spread across 2–4 sessions
• Water temperature ~15°C / 59°F (or colder, with shorter duration)

In her cohort, this dose was associated with significantly increased cold-induced thermogenesis, brown fat activity, and improvements in insulin sensitivity. The data is robust but the sample is small — don't oversell it.

My take: 3 min/day at 48°F gets me well past the Søberg dose. If you're cold-curious but minimum-effective-dose oriented, target 11 minutes a week, split into 2–4 sessions. See cold plunge protocols for the full dose-response curves.

The Finnish Sauna Dose for Mortality Reduction

The Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD) followed ~2,300 Finnish men for ~20 years.

Subsequent papers showed similar dose-response curves for cardiovascular mortality, sudden cardiac death, dementia, and Alzheimer's incidence.

Caveats: observational data, Finnish men specifically, sauna culture is embedded in lifestyle. The causal interpretation is plausible but not airtight.

Still — this is the strongest observational mortality signal of any voluntary behavior outside of "don't smoke" and "be active." 4+ sessions a week is the threshold to aim for. Details in the home sauna guide.

The Longevity Supplement Stack (With Cost)

What I actually take, monthly:

What I deliberately don't take: NMN, NR, resveratrol, TMG, anything ending in "-mab" that I imported, anything with "proprietary blend" on the label.

Full breakdown in the longevity supplement stack article.

What I Do vs What I'd Recommend

Worth being explicit here. My routine is fairly maximalist because I write about this stuff, own the gear, and have spent four years optimizing it. It's not the routine I'd recommend most people start with.

The minimum-viable version captures probably 75% of the benefit of the maximalist version for ~10% of the cost.

What I Tried and Abandoned

Honesty matters. Here's what's been on the chopping block.

NMN, 500mg/day for 9 months

Cost: ~$90/month, ~$810 total. Result: No measurable change in NAD+ on Function Health. No subjective change. Verdict: Dropped. The human evidence isn't there yet. See best NAD supplement for the full breakdown.

Resveratrol, 500mg/day for 6 months (back in 2022)

Result: Nothing. Verdict: Dropped. The Sinclair mouse studies didn't replicate in humans.

Intermittent fasting (18:6, 20:4)

Result: Lost weight, lost strength, slept worse. Verdict: Dropped. For active adults trying to preserve muscle, the cortisol cost outweighed the modest metabolic benefit.

Rapamycin (considered, not taken)

Verdict: Not for me right now. The dosing protocols in humans aren't settled, the side-effect profile is real, and the longevity data is still mouse-based. I revisit this every 12 months.

Continuous CGM

Result: Useful for the first month, then the marginal information dropped to near-zero. Verdict: Two weeks a quarter, not continuous. See best CGM for non-diabetics.

Cold therapy in the evening

Result: Wrecked my sleep. Cold's a stimulant. Verdict: Morning only.

Daily HIIT

Result: Spike in HRV variability, worse sleep, joint soreness. Verdict: 1–2× a week max. Most of my cardio is zone 2.

Aggressive blood ketone monitoring

Result: Compelling for the first month, then boring and noisy. Verdict: Dropped. Not predictive of anything I couldn't see in HbA1c.

Hydrogen water tablets

Verdict: Dropped. Placebo at $90/mo.

"Grounding" sheets

Verdict: Dropped. Use them as regular sheets.

Common Mistakes (Chasing Biohacks vs Basics)

Watching the longevity space for four years, the same mistakes show up:

1. Buying the supplement stack before fixing sleep. $500/mo of pills won't compensate for chronic 6-hour nights.
2. Optimizing the latest "longevity hack" while skipping zone 2. VO2 max alone beats 90% of the supplement stack on actual mortality data.
3. Underrating ApoB. This is the single biggest cardiovascular lever for most people. Get it under 70 mg/dL if possible. See Function Health for tracking.
4. Ignoring strength training. Sarcopenia is one of the biggest predictors of disability and mortality after 70. Lift, even if you hate it.
5. Doing fasted cardio "for autophagy." The autophagy data in humans is much weaker than the rodent data. Train fed if you're trying to perform.
6. Wearable-worship. Your Oura score is downstream of your life, not the other way around.
7. Skipping testing. Without bloodwork you're flying blind on the metrics that actually matter.
8. Chronic alcohol. Most underrated longevity input. One drink/day is not "neutral." See your HRV data.
9. Treating longevity as identity. This is gear and habits. Don't make it weird.
10. Going maximalist before mastering the basics. Bryan Johnson skipped a step you can't skip — he was already extremely healthy when he started. Most of his "wins" would have happened on a $30/mo routine.

Nothing in this article is medical advice. Some interventions discussed (cold exposure, heat exposure, supplementation, fasting, intense exercise) carry real risks for some populations. Cardiovascular disease, pregnancy, certain medications, and a range of medical conditions all change the risk-benefit math.

FAQ

What's the single most important longevity intervention?

Exercise. Specifically, a combination of zone 2 cardio (180+ min/week), VO2 max work (1–2×/week), and strength training (3×/week). No supplement, no biohack, no protocol comes close.

What's the biggest mistake people make?

Buying supplements before fixing sleep and exercise. The order of operations is: sleep → exercise → nutrition → testing → recovery interventions (sauna, cold) → supplements. Most people start backward.

Is Bryan Johnson's Blueprint worth copying?

Some of it (consistency, testing discipline, early bedtime). Most of it (100-supplement stack, plasma exchange, rapamycin at his dose) isn't validated in humans and isn't cost-justified.

Peter Attia vs Bryan Johnson — who's more right?

Peter Attia. By a lot. His framework is evidence-grounded, his recommendations are practical, and he's transparent about what's speculative. The "Four Horsemen" framework alone is the most useful organizing principle in this space.

Is NMN worth it?

I don't think so. After 9 months at 500mg/day, my NAD+ didn't change measurably. Human longevity data is non-existent. Pass for now. See best NAD supplement for if-you-must options.

How often should I get bloodwork?

Quarterly is overkill for most people but optimal for tracking interventions. Annually is the practical minimum if you're doing this seriously. See the at-home health testing guide for the panel I'd run.

Is cold therapy actually anti-aging?

Mood, dopamine, brown fat, glucose tolerance — yes. Direct longevity mortality data — weaker. The Søberg work is the strongest evidence for metabolic effects. I include cold for the metabolic + neurological benefits, not because it'll add years.

Is sauna actually anti-aging?

Closest to "yes" in the observational data. The Finnish Kuopio cohort shows 40%+ all-cause mortality reduction at 4+ sessions/week. See the home sauna guide.

What about red light therapy?

Modest evidence for muscle recovery, skin, and possibly mitochondrial function. Not a top-5 longevity intervention but a reasonable add-on once the basics are locked. Red light therapy guide covers the dose-response.

Should I take rapamycin?

I don't currently. The protocols aren't settled, the side-effect profile is real, and the evidence is largely mouse-based. I reconsider this every 12 months. Talk to a physician with actual longevity-medicine experience (not a TikTok one) before considering it.
