How the score works

Nine domains, 120 points, and what each one is actually measuring.

The method in one paragraph

Every marker you enter is scored against an evidence-informed target range and converted to a 0–1 value. Markers are averaged within their domain, domains are weighted by the point values below, and the total is rescaled to 0–100. Only domains you actually provided data for are counted, so leaving something blank never reduces your score — it reduces confidence instead.

Confidence reflects data completeness, not diagnostic certainty. Missing values lower confidence, not your score. Adding results can change your score in either direction.

The nine domains

Body composition
15 pts

How much fat you carry and where — measured by BMI and waist-to-height ratio.

Glucose & insulin
20 pts

How well your body handles sugar, from HbA1c, fasting glucose and insulin.

Liver health
15 pts

Liver enzyme levels and fibrosis risk (ALT, AST, GGT, FIB-4).

Cardiovascular health
20 pts

Inflammation & nutrients
10 pts

Background inflammation and key nutrient stores (hsCRP, ferritin, vitamin D, B12).

Kidney health
10 pts

How well your kidneys filter, from eGFR, creatinine and urine ACR.

Thyroid health
10 pts

Thyroid hormone balance, which sets your baseline metabolic rate.

Exercise & recovery
10 pts

Movement, strength training, sitting, sleep, smoking and alcohol.

Food & nutrition
10 pts

Everyday food habits: protein, vegetables, fruit, legumes and healthy fats.

Marker explanations

ALT / SGPT

Liver enzyme; SGPT is the common Indian term.

AST / SGOT

Liver/muscle enzyme; SGOT is the common Indian term.

ALP

Alkaline phosphatase; interpreted with GGT and clinical context.

FIB-4

Age, AST, ALT and platelets estimate liver fibrosis risk.

eGFR

Estimated kidney filtration; more useful than creatinine alone.

Urine ACR

Detects kidney stress even when eGFR is normal.

Haemoglobin

Oxygen-carrying protein. Low values can reflect anaemia or inflammation.

Non-fasting glucose

Useful context, but meal timing matters.

HbA1c

Average blood glucose over about 2–3 months.

TyG Index

Triglyceride-glucose index; insulin resistance proxy.

Waist

Central fat marker; interpreted by sex and ancestry.

Structured exercise

Planned exercise only, not housework or incidental activity.

Resistance training

Aim for at least two sessions weekly.

Homocysteine

Influenced by B vitamins, kidney, thyroid and genetics.

Protein servings

Habit marker for muscle, satiety and recovery.

Vegetable servings

Proxy for fibre, micronutrients and diet quality.

Whole fruit

Fibre and micronutrients. Fruit juice is not counted.

Legumes

Dal, chickpeas, beans and lentils: fibre, protein, slow carbs.

Healthy fat foods

Nuts, seeds, oily fish, ghee and common cooking oils.

Starting templates

Exercise starting plan

Daily movement: 7,000–8,000 steps/day. Strength: bodyweight exercises at least 2 sessions/week.

Simple meal template

¼ plate protein, ½ plate vegetables, ¼ plate whole grains/high-fibre carbs. Add legumes often; use sensible portions of healthy fats. Water as the main drink.

Common myths

You do not need crash diets or expensive supplements. Small, consistent changes matter.
