Medicine 3.0: The Outlive Protocol Made Accessible

Readers of Peter Attia's Outlive: The Science and Art of Longevity tend to walk away with the same two reactions. First: This is exactly how medicine should work. Second: How do I actually do this?

The book's core thesis hits hard because it is true. The healthcare system most of us depend on, what Attia calls Medicine 2.0, was built to treat disease after it shows up. For the four biggest killers (cardiovascular disease, cancer, neurodegeneration and metabolic dysfunction), that approach arrives late. By the time you have symptoms, you have often missed the window for the most effective interventions by a decade or more.

Attia calls the alternative Medicine 3.0: proactive, data-driven, personalized. The goal is not just adding years to your life. It is adding life to your years: staying strong, independent and mentally sharp deep into your 70s, 80s and beyond.

The catch? Attia's own practice is not open to most people, and most physicians still practice Medicine 2.0 because the reimbursement system pays them to.

We built Rebel Health Alliance to close that gap. I have spent my career watching patients fall through the cracks of reactive medicine, and I am done pretending the system works.

What Medicine 3.0 Actually Demands

If you have read Outlive, you know the framework breaks down into specific clinical pillars. Here is what each one requires, and what your current doctor almost certainly is not doing.

1. Advanced Biomarker Testing (Not Standard Labs)

Your annual physical probably runs 15 to 20 markers. Basic metabolic panel, lipid panel, CBC. The reference ranges are calibrated to detect disease, not to catch the trajectory toward it.

A real Medicine 3.0 lab panel looks nothing like that:

• ApoB, the particle count behind atherosclerosis. The European Atherosclerosis Society's 2020 consensus statement (Borén and colleagues, European Heart Journal) concluded that LDL particles cause atherosclerotic cardiovascular disease and that ApoB is a more accurate measure of that risk than LDL-C alone. Most primary care doctors still do not order it.
• Lp(a), a genetically determined cardiovascular risk factor most doctors never check. You cannot act on what you do not measure.
• Fasting insulin, arguably the earliest signal of metabolic dysfunction. When Crofts and colleagues re-examined Joseph Kraft's decades of glucose tolerance tests (Diabetes Research and Clinical Practice, 2016), just over half of people with normal glucose tolerance had hyperinsulinemia anyway. Longevity physicians aim for under 6 to 8 uIU/mL; most lab reference ranges call anything under 25 "normal." That is the difference between detecting disease and detecting the drift toward it.
• hs-CRP, systemic inflammation, a root driver across nearly every chronic disease category.
• Homocysteine, a cardiovascular and neurological risk marker.
• Full thyroid panel: TSH, free T3, free T4, reverse T3, thyroid antibodies. Not just TSH.
• Complete hormone panel: testosterone, free testosterone, estradiol, DHEA-S, SHBG, cortisol.
• Omega-3 index. Harris and von Schacky (Preventive Medicine, 2004) proposed the red blood cell omega-3 index as a risk factor for coronary death, with 8% or higher associated with the greatest protection and 4% or lower with the least.
• HbA1c, fasting glucose and fasting insulin together, the metabolic trifecta that shows how your body handles energy.
• Vitamin D, B12, folate, ferritin, magnesium RBC

At Rebel Health Alliance, members start with an initial panel of about 30 tests, drawn from more than 3,000 available diagnostic tests, and the physician tailors the workup from there. Not because more is automatically better, but because these specific markers, tracked over time, give us the resolution to intervene years before disease shows up. Here is how our process works.

2. Cardiovascular Prevention Beyond a Statin Script

I will be honest: I spent years writing statin prescriptions based on LDL-C and hoping for the best. That is what training taught me. It took me longer than I would like to admit to recognize how incomplete that approach was.

Attia spends multiple chapters of Outlive arguing that cardiovascular prevention requires far more, and the evidence has caught up. Real risk assessment starts with ApoB-driven lipid management: targeting particle count, not just cholesterol concentration. It means Lp(a) screening, which the European Atherosclerosis Society consensus (Nordestgaard and colleagues, European Heart Journal, 2010) recommends measuring at least once in people at intermediate or high cardiovascular risk. Coronary artery calcium scoring gives you direct plaque imaging. And you cannot ignore the metabolic context: insulin resistance drives cardiovascular risk regardless of your cholesterol numbers, something Reaven laid out in his 1988 Banting Lecture in Diabetes, and the field is only now fully internalizing.

None of this is exotic. It is all evidence-based. It just does not fit in a seven-minute office visit.

3. Metabolic Health: The Root System

Here is what keeps me up at night as a physician. Metabolic dysfunction is not one disease. It is the root system feeding cardiovascular disease, many cancers and neurodegeneration at the same time.

I remember the patient who changed my thinking on this: a 52-year-old man, lean, active, "perfect" cholesterol. His fasting insulin was 22. Nobody had ever checked it. Three years later he had a cardiac event. That story plays out constantly, and it does not have to.

Reaven's foundational work on insulin resistance syndrome showed the link between insulin resistance, hypertension and lipid abnormalities decades ago, and found insulin resistance in roughly a quarter of non-obese people with normal glucose tolerance.

The markers that matter are the ones most people have never seen on a lab report. Fasting insulin. HOMA-IR, the calculated insulin resistance score. The triglyceride-to-HDL ratio, a cheap proxy for metabolic health that any doctor could order but few bother to. HbA1c tracked as a trend over time, not a single snapshot.

At Rebel, every member's nutrition, training and supplementation protocol is built on their metabolic data. Generic guidelines do not cut it when the goal is optimization.

4. Exercise: The Drug Nobody Prescribes

Attia is blunt about this, and he is right: exercise is the most powerful longevity tool we have. No drug comes close.

The data is striking. Mandsager and colleagues (JAMA Network Open, 2018) followed more than 122,000 patients who had undergone treadmill testing at the Cleveland Clinic. Those in the lowest fitness group had about five times the all-cause mortality of those with elite fitness, and being below average rather than above average carried a 41% higher risk. The mortality penalty for low fitness was comparable to or greater than that for coronary artery disease, smoking or diabetes.

Then there is muscle and what happens when you lose it. Sarcopenia, the progressive loss of muscle with age, drives frailty, falls and metabolic decline. It is the thing that eventually takes away your ability to live on your own terms. Frankly, that scares most of my patients more than dying does. Shailendra and colleagues (American Journal of Preventive Medicine, 2022) pooled ten cohort studies and found that any amount of resistance training was associated with 15% lower all-cause mortality, with the largest benefit, about 27%, at roughly 60 minutes per week. García-Hermoso and colleagues (Archives of Physical Medicine and Rehabilitation, 2018) found higher grip strength associated with 31% lower all-cause mortality across nearly two million people.

Zone 2 cardio supports the aerobic side. San-Millán and Brooks (Sports Medicine, 2018) showed that the ability to burn fat at moderate intensity, and to keep blood lactate low while doing it, separates professional athletes from moderately active adults and from people with metabolic syndrome, a direct window into mitochondrial function. Stability and mobility training round it out.

Knowing all this is one thing. Having a strength coach who shares a thread with your physician and dietitian and builds a periodized program off your labs is another. That is the Outlive framework in practice. That is what Rebel Peak members get.

5. Nutritional Biochemistry (Not Another Diet)

I have watched patients sabotage excellent training programs with poor nutrition for twenty years. One man trained six days a week, looked great in the gym, and his metabolic panels told a completely different story. Medicine 3.0 does not hand you a meal plan and wish you luck. It uses your labs and your metabolic response to determine what your body actually needs.

Protein targets based on lean body mass and training demands: Phillips and colleagues (Applied Physiology, Nutrition, and Metabolism, 2016) put the range for optimal health in adults at 1.2 to 1.6 grams per kilogram per day, well above the RDA most people anchor to. Carbohydrate tolerance guided by insulin and glucose data, not ideology. Micronutrient targets based on actual blood levels. Supplementation driven by tested deficiencies, not by whatever had the best ad last week.

Our registered dietitians work directly with our physicians. Your nutrition plan is a clinical intervention, not a PDF you will forget about by Thursday.

6. Physician-Supervised Hormone Optimization

This section is personal for me. I watched my own father's energy, mood and cognitive sharpness decline through his 50s. His doctor told him it was "normal aging." It was not, or at least it did not have to be.

Testosterone, estrogen, DHEA and thyroid hormones all decline with age, and that decline drives much of what we experience as "getting old." Attia discusses this in Outlive, and any honest longevity physician will tell you it matters. Araujo and colleagues (Journal of Clinical Endocrinology and Metabolism, 2011) reviewed 21 studies of endogenous testosterone and mortality in men and found the studies with lower testosterone levels and older subjects tended to report higher relative risks of death, which tracks with what I see clinically.

"Normal for your age" is the phrase that drives me crazy. The question we should be asking: what hormonal environment gives this specific person the best shot at maximum healthspan?

At Rebel, hormone optimization is supervised by physicians, verified by follow-up labs, and adjusted based on data. Every protocol is personalized and monitored, because that is what responsible medicine looks like.

The Accessibility Problem

Here is the part of the Medicine 3.0 story nobody in the longevity space wants to talk about: the people who built the framework priced most people out of it.

The science is not locked behind a paywall. The lab tests are commercially available. The evidence is published in peer-reviewed journals anyone can read. But the delivery model has been reserved for people who can write very large checks to a practice that may not even be taking new patients.

The bottleneck was never knowledge. It was the delivery model. By building a 100% virtual, team-based practice without office leases, bloated admin staff or third-party billing overhead, we deliver physician-led Medicine 3.0 at a price most professionals can actually pay.

Memberships are per person. Rebel Peak, the full coordinated team (physician, registered dietitian, certified strength coach, with physical therapy and genetic counseling folded in when your protocol calls for them), is $697 a month or $6,970 a year. Rebel Health, the physician-only membership with the same 10-tier longevity protocol and care coordination, is $399 a month or $3,999 a year. A spouse gets 15% off their own membership. There is no setup fee. Lab panels are billed separately at wholesale cash-pay rates, about $450 for the initial panel. See what the approach looks like in practice.

What the First Year Actually Looks Like

The first 90 days: baseline. A 60 to 90 minute initial visit with your physician. The initial lab panel at Quest, plus DNA and DunedinPACE pace-of-aging testing when appropriate. Your physician builds your Tier 1 Foundation plan from the results (insulin resistance, cardiovascular risk, metabolism) and owns your one-year, three-year and ten-year plan. On Rebel Peak, your strength coach and dietitian start programming off the same bloodwork in the first weeks. Care coordinators book the labs and appointments.

The rest of year one: optimization. Your physician adjusts based on how you are actually responding, not how the textbook says you should. Follow-up labs on the schedule your physician sets, so decisions are made on trajectories, not snapshots. Medication or supplement changes when the data calls for them. Continuous coaching. And the whole time, your physician is on demand: message anytime, replies usually same day, timely virtual visits. This is continuous care, not periodic check-ins.

That is the Outlive framework as an operating system, not a book on your nightstand.

The Outlive Protocol, Operationalized

Peter Attia gave millions of readers a framework. Outlive explained what proactive medicine looks like and why it matters. That was a genuine contribution.

But reading about it and doing it are different things entirely.

Rebel Health Alliance is where the Outlive framework actually gets executed. A physician-led team that runs the Medicine 3.0 model against your data and your goals, at a price that reflects what healthcare should cost when you strip out the bureaucracy.

If you have read the book and you are ready to stop highlighting passages and start living them, book a 20-minute call.

Frequently asked questions

What is the difference between Medicine 2.0 and Medicine 3.0?
Medicine 2.0 is reactive: it waits for disease to appear, then treats it. Medicine 3.0 is proactive: it uses advanced diagnostics, biomarker tracking and personalized interventions to prevent disease and extend healthspan years before symptoms would appear. Peter Attia popularized the term in Outlive (2023).

Do I need to have read Outlive to benefit from this approach?
No. The book is excellent context, but your physician at Rebel implements the framework whether or not you have read it. The protocols are based on published evidence, not on one author's book.

How does Rebel differ from ordering my own labs through a testing service?
Direct-to-consumer lab services make testing accessible. Where they stop is where we start: interpreting those labs in context, building a clinical protocol around them, and adjusting that protocol over time with a physician who knows your history. Testing without a treatment protocol is data without direction.

Is Rebel Health Alliance available nationwide?
Yes. Care is 100% virtual in all 50 states, with blood draws at a Quest location near you.

Can I keep my existing primary care doctor?
Yes. Many members keep their PCP for acute care and sick visits while using Rebel for proactive longevity medicine. The two are complementary, and we are happy to coordinate with your existing doctor.
