A daily health score built on validated frameworks from the American Heart Association, the ACSM, and six other leading medical societies. Four pillars. One living number.
Not a fitness app. Not a wellness product.
An evidence-based interpretation of your health.

Category Rejection
The ones that celebrate streaks without interpreting data. The ones that track your sleep but have nothing to say about it. The ones built on habit loops, not evidence. A generation of wellness tools optimized for engagement, not health.
You already know something is missing. The question was never whether to take your health seriously. It was whether any tool deserved your seriousness back.
"Wellness theater is the category we refuse to join."
The Score
The NutraHealth Score is a composite of four weighted pillars, recalculated every day against scoring tables derived from peer-reviewed guidelines. No proprietary formulas. No invented metrics.
Built on validated frameworks from the American College of Sports Medicine, the American Heart Association, the National Sleep Foundation, and the Academy of Nutrition and Dietetics — not invented metrics, not proprietary AI guesses.
Pillar Architecture
Exercise
Your physical activity is scored against ACSM guidelines for aerobic capacity, strength training frequency, and daily metabolic output. Steps matter less than work. VO2 max estimation is factored into baseline cardiorespiratory fitness.

Sleep architecture, not just duration. The score weighs REM proportion, sleep efficiency, and night-to-night consistency against National Sleep Foundation staging criteria. Apple Health sleep data feeds this pillar continuously.

Diet quality over calorie counting. Macro balance, meal timing, micronutrient targets, and adherence to evidence-based dietary patterns from the Academy of Nutrition and Dietetics. The AI generates your specific targets from your lab panel and metabolic profile.

Your bloodwork, read correctly. Lab panels are processed against clinical reference ranges from the American College of Physicians — not algorithm-generated 'optimal' ranges. Upload your exams directly; the AI analyzes and scores each marker.

The cardiac risk score applies a modified version of the ACC/AHA pooled cohort equations, extended with inflammatory markers and autonomic nervous system indicators not captured in standard clinical screening.
Upload any standard lipid panel, metabolic panel, or CBC. The score integrates automatically. No manual entry required.

Stress Score
Chronic cortisol elevation suppresses free testosterone, stalls body composition, and compromises cardiovascular recovery. Your stress score measures the biological axis that shapes the output of every other pillar. It doesn't tell you to breathe. It tells you why you should.
Cohen Perceived Stress Scale, 10-item version. Validated across 12,000+ adults in NIH-funded studies. Scored against clinical cutpoints, not proprietary wellness app bands.
hs-CRP as a primary physiological stress indicator, drawn from your lab panel. Appears in the Cardiac Risk Score as well — see methodology note below.
HRV from Apple Health or Whoop. Autonomic nervous system state is the most direct continuous window into chronic stress burden and parasympathetic recovery capacity.
Derived from lab panel cortisol values and HRV patterns. Chronic cortisol elevation suppresses free testosterone, stalls body composition, and compromises cardiovascular recovery.
Night-to-night instability in deep sleep proportion and waking frequency, drawn from Apple Health. Sleep architecture disruption is both cause and consequence of chronic stress. The model tracks both directions.
hs-CRP appears in both the Cardiac Risk Score and the Stress Score. Cardiovascular disease and chronic stress share the inflammatory axis. We weight the same marker differently in each model: the same biology, two clinical lenses.
Your stress score is the variable we monitor most closely during FatCore Protocol. Elevated cortisol invalidates metabolic recalibration.
Premium intervention
Twelve months of continuous recalibration.
FatCore Protocol is not a diet. It is a precisely calibrated intervention built on your VO2 max, metabolic profile, and lab panel — continuously updated through Apple Health.
Estimated from Apple Health cardio data and validated against your resting and active heart rate profile.
Custom meal plans and macro targets generated from your exams. Updated each protocol cycle.
Evidence-based supplement support matched to your identified deficiencies.
Weekly recomposition targets. Muscle retention as a primary metric — never just weight.
Heart rate, HRV, sleep, and activity data feed the protocol automatically.
By day fourteen you have a resting metabolic rate estimate derived from your lab panel, a VO2 max calibrated against your Apple Watch cardiorespiratory response, and macronutrient targets your dietitian would recognize as clinically grounded. Nothing has been adjusted yet. This phase exists to make the adjustment accurate.
Your macros have been periodized three times, adjusted against your training data and current stress score. On days when elevated cortisol is detected, the AI nutrition model holds your caloric target conservatively: metabolic recalibration does not proceed against a stressed endocrine system. Lab-derived biomarker updates from your panel override the baseline automatically. The protocol adapts. You do not re-enter data.
By day fifty, body composition targets have shifted from active recalibration to recomposition maintenance. FatCore closes; your follow-up year begins. Four quarterly recalibration windows, each triggered by a new lab panel, continue the adjustment cycle. The protocol assumed you would respond imperfectly. The twelve months were built for that.
Continuous data layer
NutraHealth connects to Apple Health to read resting heart rate, sleep architecture, daily movement, and caloric expenditure. Not to aggregate numbers — to build context that improves your score.
Your Apple Watch already knows things about your body that most labs miss. We interpret that stream alongside your clinical data to produce a score your cardiologist would recognize.
