The Numbers That Changed: What Actually Moves in Year One of Membership

You want to know what happens when someone commits to a structured health optimization program for 12 months. Not the theory. Not the testimonials. The numbers.

Protocol has tracked biomarker data across our full membership. Here’s what actually moved, how fast it moved, and — just as important — what did not move. Honesty about results builds more trust than cherry-picking wins.

What Moves Fast: Weeks 6-12

ApoB: 27% to 69% Optimal Attainment

ApoB — apolipoprotein B — is the single best blood marker for cardiovascular risk. Each ApoB particle represents one potentially atherogenic lipoprotein circulating in your blood. Lower is better. Protocol’s target: below 100 mg/dL for standard risk, below 70 mg/dL for elevated risk.

At intake, 27% of members had ApoB in the optimal range. During membership, that number rose to 69%. Median ApoB across the membership: 79 mg/dL. And 88% of members are currently below 100 mg/dL.

This moves fast because for Tier A and Tier B members — those with ApoB above target — the intervention often includes medication (typically a statin, sometimes ezetimibe or a PCSK9 inhibitor). Medication is part of the protocol. Prescribing a statin when the evidence supports it isn’t a shortcut — it’s evidence-based medicine applied to the single strongest modifiable risk factor for heart disease.

Lifestyle modifications — dietary changes, exercise, weight management — contribute to ApoB reduction, but the magnitude of change for members starting above 130 mg/dL is almost always medication-driven. That’s not a failure of lifestyle. It’s the pharmacology doing what it was designed to do, alongside the lifestyle changes that address the other risk factors medication doesn’t touch.

hsCRP Reduction

High-sensitivity C-reactive protein — hsCRP — is a marker of systemic inflammation. It responds to both lifestyle changes (sleep improvement, stress reduction, dietary modification, weight loss) and medication (statins have an anti-inflammatory effect independent of their lipid-lowering action).

Members starting with elevated hsCRP (above 2.0 mg/L) typically see measurable reductions within 8-12 weeks of beginning their protocol. The combination of structured lifestyle intervention plus targeted medication, when indicated, produces a faster response than either alone.

Blood Pressure Optimization

Protocol uses 24-hour ambulatory blood pressure monitoring (ABPM) rather than single office readings. ABPM captures your blood pressure during sleep, during work, during exercise, during stress — the full picture that a one-time cuff reading in a doctor’s office cannot provide.

Blood pressure responds to intervention within weeks. Salt reduction, potassium optimization, stress management, improved sleep consistency, and — when indicated — medication. Members with masked hypertension — normal in the office, elevated during the day — are frequently caught by ABPM and treated before end-organ damage accumulates.

What Moves at Medium Speed: 3-6 Months

VO2 Max Improvement

VO2 max — the maximum rate at which your body can use oxygen during exercise — is arguably the single strongest predictor of all-cause mortality. It responds to structured training, but not overnight.

With Protocol’s exercise programming (Protocol 4) — typically 2 sessions per week of zone 2 cardio (60-70% heart rate reserve) plus 2-3 resistance training sessions — measurable VO2 max improvement begins around month 3 and continues through month 12 and beyond.

The rate of improvement depends heavily on starting fitness level. A deconditioned member starting at 25 mL/kg/min can see 15-20% improvement in 6 months. A moderately fit member starting at 38 mL/kg/min might see 5-10%. Both trajectories are clinically meaningful.

Sleep Consistency Improvement

Sleep midpoint standard deviation — the consistency of when you sleep — is Protocol’s lead sleep metric. Improving it takes time because you’re retraining a circadian pattern that may have been erratic for years.

Most members see measurable improvement (a reduction of 15+ minutes in sleep midpoint SD) within 8-12 weeks of consistently anchoring their wake time. Full stabilization — getting sleep midpoint SD below 30 minutes and keeping it there — typically takes 3-6 months.

The intervention is behavioral, not pharmacological: fixed wake time (weekdays and weekends), narrowed weekend drift, strategic light exposure in the morning, limited bright light and screens in the evening. Simple in concept. Not easy in practice. But the consistency of sleep timing improves measurably when someone has a care team monitoring the data and coaching the adjustments.

CGM-Guided Dietary Patterns Become Habit

Protocol’s two-week CGM trial (Protocol 3) identifies each member’s specific glucose response patterns — which foods spike them, which meal combinations moderate spikes, how exercise timing affects glucose, how sleep quality modulates the next day’s responses.

The CGM comes off after the trial. The dietary patterns it revealed — protein anchoring, post-meal walks, specific food swaps — take 3-6 months to solidify into automatic habits rather than conscious interventions. By month 6, most members aren’t thinking about these patterns anymore. They’re just eating and moving differently.

What Takes Longer: 6-12 Months

Body Composition Changes

DEXA-visible changes in lean mass and visceral adipose tissue (VAT) take time. Muscle grows slowly. Fat redistribution happens gradually. Expecting a dramatic DEXA change at 3 months is unrealistic for most members.

At the 6-month scan, members in a structured resistance training program with adequate protein intake typically show a measurable increase in ASMI (Appendicular Skeletal Muscle Mass Index) and a reduction in VAT. By 12 months, these changes are clinically meaningful — often a 1-2 kg increase in lean mass and a reduction in visceral fat, even when total body weight changes minimally.

Protocol doesn’t use weight as a progress metric for this reason. A member who gains 3 pounds of muscle and loses 4 pounds of visceral fat has dramatically improved their health profile. The scale says they lost 1 pound. The DEXA says they transformed their body composition. (More on why body composition beats weight.)

Protein Intake Habits Fully Established

Hitting age-stratified protein targets — 1.6-2.0 g/kg depending on age — requires restructuring meals in ways that take months to become second nature. Most members get to 80% of their target within the first month (once they see how far off their baseline intake actually is). Getting to consistent, daily target attainment across all meals — including the per-meal minimums of 30-40g — is a 6-12 month project.

The Aggregate Picture: Biological Age and Cardiovascular Risk

Biological Age: -3.8 Years Average

Protocol calculates biological age using the Levine PhenoAge algorithm — a validated model based on 9 blood biomarkers (albumin, creatinine, glucose, CRP, lymphocyte percent, mean cell volume, red cell distribution width, alkaline phosphatase, and white blood cell count) that predicts mortality risk independent of chronological age.

Across our members, the average biological age gap is -3.8 years — meaning the average member is biologically 3.8 years younger than their chronological age. 72% of members are biologically younger than their calendar age.

Two caveats worth stating openly. First, Levine PhenoAge is one of several biological age algorithms. It’s validated and published, but different algorithms can produce different numbers for the same person. Second, Protocol’s membership is a self-selected population — people who seek out a health optimization practice are likely already healthier and more health-conscious than the general population. The -3.8 year average reflects both Protocol’s interventions and the baseline health advantage of a motivated, self-selected group.

We report this number because it’s real and it’s ours. We caveat it because intellectual honesty demands it.

Cardiovascular Risk: 95% Maintained or Improved

Using age-adjusted cardiovascular risk scoring — which accounts for the fact that everyone’s risk goes up by 1 year of age between assessments — 95% of members maintained or improved their cardiovascular risk profile. Their risk either stayed flat (despite aging) or decreased.

This is scored without medication changes factored in — meaning we’re measuring the raw biomarker trajectory. When a member starts a statin and their ApoB drops from 140 to 75, that improvement is real. The medication is doing what it should. And the member is measurably safer because of it.

What We Cannot Claim: The A1c Question

A1c — glycated hemoglobin, a 90-day average of blood glucose — is flat across Protocol’s membership data. We cannot claim that membership improves A1c.

The longitudinal evidence is insufficient. Most members enter with normal A1c (below 5.7%), which means there’s limited room for improvement. For the small number of members with elevated A1c at intake, the data set is too small and the follow-up period too short to draw conclusions.

This matters because it would be easy to leave out. Every other number in this article is positive. A1c is neutral. Omitting it would make the results page look cleaner. But if you’re making a decision about whether to join Protocol, you deserve to know what we can demonstrate and what we can’t. A1c improvement is something we can’t demonstrate — yet.

What Honest Results Look Like

Some biomarkers improve because of medication. ApoB is the clearest example. A statin prescription isn’t a bypass of the protocol — it is the protocol working. The evidence for statin therapy in primary prevention for people with elevated ApoB is strong. Prescribing it isn’t a shortcut. Withholding it in the name of “lifestyle only” would mean ignoring evidence.

Some biomarkers improve because of behavior change. Sleep consistency, VO2 max, body composition, dietary patterns. These take longer and require sustained effort.

Some biomarkers respond to both. hsCRP responds to lifestyle and medication. Blood pressure responds to lifestyle and medication. Cardiovascular risk responds to everything.

And some biomarkers don’t move in a meaningful way. A1c, as noted. Certain genetic markers that don’t respond to intervention. Some inflammatory markers driven by conditions outside Protocol’s scope.

The pattern across our membership and 12 months is clear: structured, evidence-based intervention — combining clinical assessment, targeted medication when indicated, coached behavior change, and continuous monitoring — produces measurable improvement in the biomarkers that predict disease, disability, and early death.

Not in every biomarker. Not in every member. Not overnight. But in the metrics that matter most, on the timelines that biology allows.

The Timeline Summarized

Timeframe	What Moves	Primary Driver
