The science behind LP Score

The LP Score is a 0-100 composite that estimates how fast or slow you are aging based on modifiable lifestyle factors. It is not an epigenetic clock — it is a behavioral proxy for biological age, grounded in published longevity research and personalized over time.

The seven pillars

Longevity Pulse aggregates the modifiable factors with the largest documented effect on all-cause mortality. The current pillar set is:

• Nutrition — diet quality, plant-load, processed-food load, weekly variety, fermented foods.
• Movement — weekly minutes of moderate and vigorous activity, strength training, sedentary hours, VO₂max where measured.
• Sleep — duration, consistency, deep-sleep proportion, REM proportion.
• Body Composition — weight, waist, body-fat percentage, lean mass, derived ratios (BMI, WHtR, FFMI).
• Mind — mindfulness frequency, stress events, social connection.
• Recovery — heart-rate variability trend, resting heart rate, perceived recovery, rest days.
• Biomarkers — fasting glucose, cholesterol panel, hs-CRP, vitamin D, hormones, captured manually or via lab-report OCR.

How the score is computed

1. Pillar sub-score (0-100) — each pillar computes a sub-score by comparing your metrics against longevity-optimal ranges drawn from the published research below.
2. Weighted composite (0-100) — the sub-scores are combined with research-informed weights into your headline LP Score.
3. Biological age estimate — the LP Score is mapped to a years-offset against your chronological age. An LP Score of 80 at chronological age 40, for example, corresponds to a lower estimated biological age. The mapping is calibrated against published VO₂max-age curves and all-cause-mortality data.
4. Aging rate — the change in biological age per unit of chronological time. A rate below 1.0 means you are aging slower than time itself.

Pillar weights and the algorithm version are stamped on every score (algVersion). Historical scores never change retroactively when the formula evolves — past scores stay frozen under their original version and new scores use the updated formula going forward.

Research grounding

The LP Score is grounded in peer-reviewed work including:

• Movement: Ekelund U et al. (2019). Dose-response associations between accelerometry measured physical activity and sedentary time and all cause mortality. BMJ 366:l4570.
• Nutrition: Sofi F et al. (2014). Mediterranean diet and health status: an updated meta-analysis. Public Health Nutr 17(12):2769-82.
• Sleep: Cappuccio FP et al. (2010). Sleep duration and all-cause mortality: a systematic review and meta-analysis. Sleep 33(5):585-92.
• Recovery / HRV: Thayer JF et al. (2012). A meta-analysis of heart rate variability and neuroimaging studies. Neurosci Biobehav Rev 36(2):747-56.
• Mind: Black DS, Slavich GM (2016). Mindfulness meditation and the immune system. Ann N Y Acad Sci 1373(1):13-24.
• Biomarkers: Levine ME et al. (2018). An epigenetic biomarker of aging for lifespan and healthspan. Aging 10(4):573-91 (PhenoAge).

Limitations

• The LP Score depends on the honesty and completeness of the data you provide. Garbage in, garbage out.
• It is not a diagnostic tool. See our medical disclaimer.
• It does not replace clinical biological-age tests or routine medical check-ups.
• Day-one scores are directional. The aging-rate trend becomes meaningful after roughly three months of consistent input.
