+ New Scan

Tracks your weight over time with a 4-week moving average (dashed line). The green zone shows your BMI-healthy weight range. If a target weight is set, a projection line estimates time to reach it.

Body fat % (left axis) and muscle mass (right axis) plotted together. Horizontal annotations show ACE/ACSM fitness tiers adjusted for your sex and age. The ideal trend: fat going down while muscle stays flat or rises.

Visceral fat index mapped to CT-equivalent cm². Color zones: green <80 (healthy), yellow 80–100 (caution), red >100 (visceral obesity). This fat type is the most responsive to HIIT and dietary changes.

Stacked bar showing your 5-component wellness score over time: BMI, Body Fat, Muscle, Metabolic (WHtR), and Recovery (BMR+hydration). Each component is scored out of 20. Look for the total bar height increasing over time.

Advanced Metrics

Detailed body composition analytics

Fat-Free Mass Index tracks your muscularity normalized for height. Horizontal lines mark development tiers (sex-specific). Natural genetic ceiling is approximately FFMI 25 (male) / 22 (female).

Skeletal Muscle Index (AWGS 2019 criteria). Red = sarcopenia risk, Yellow = adequate (just above cutoff), Green = good buffer, Cyan = excellent. The dashed green line shows the age/sex median — staying above it means you have more muscle than the average person your age.

Waist-to-Height Ratio — keep your waist below half your height. A better cardiometabolic risk predictor than BMI alone. Works across all ethnicities and ages.

Basal Metabolic Rate (solid) vs age/sex reference (dashed). Higher muscle mass drives higher BMR. Each kg of muscle adds ~13 kcal/day. A rising BMR line means your metabolism is improving.

Stacked area showing lean mass (cyan) vs fat mass (yellow) over time. The ideal trend: lean mass grows while fat mass shrinks. Total height = body weight.

Segmental Progression

Arm & leg muscle, fat, and symmetry trends over time

Radar comparing your first scan (gray) to your latest (cyan) for each limb's muscle mass. Look for the cyan shape to expand outward, especially in previously weaker areas.

Muscle mass progression for each limb over time. Arms and legs tracked separately. Look for all lines trending upward — faster growth in lagging limbs means improving balance.

Fat percentage per limb over time. Arms and legs tracked separately. Ideally all lines trend downward together. Asymmetric fat loss can indicate measurement positioning differences.

Right/Left muscle ratio over time. A value of 1.0 = perfect symmetry. Deviation >5% suggests imbalance. Unilateral exercises (single-arm rows, lunges) help correct asymmetry.

Body water percentage over time. Higher muscle mass naturally increases hydration %. The green line marks the optimal threshold for your sex. Measure consistently: fasted, well-hydrated, same time.

Bone mass trend. Normally stable in adults. Significant changes may indicate measurement conditions. Resistance training and adequate calcium/vitamin D support bone density.

Load-Capacity Index (Fat Mass / Fat-Free Mass). A value below 0.35 indicates healthy body composition. Values above 0.50 are associated with elevated cardiometabolic risk (meta-analysis 2024: OR 4.24 for metabolic syndrome at LCI ≥0.70).

Health Index Insights

What each index means, thresholds, and how to improve

Body Shape Analytics

Trends from tape measurements

Chest, neck, and arm circumferences over time. Increasing chest and arm measurements with stable/decreasing waist indicates effective recomposition.

Waist and hip circumferences. A decreasing waist with stable hip indicates fat loss from the most metabolically dangerous depot. WHR = waist/hip — keep below 0.90 (M) or 0.80 (F).

Thigh and calf circumferences. Stable or increasing measurements during fat loss indicate preserved or gained lower-body muscle mass.

WHR (Waist-Hip Ratio) and BRI (Body Roundness Index). These anthropometric indices are validated predictors of cardiometabolic risk independent of BMI. Decreasing trends indicate improving body shape.

Navy method (tape-based) vs BIA (bioimpedance) body fat estimates. A difference >5% may indicate measurement inconsistency or hydration effects on BIA. The Navy method uses waist, neck, hip, and height.

Metabolic Analytics

Blood biomarker trends and computed indices

Total cholesterol, HDL (protective), LDL, and triglycerides over time. Ideal: TC <200, HDL >40/50 (M/F), LDL <100, TG <150 mg/dL. Exercise and diet changes typically show results in 8–12 weeks.

HOMA-IR measures insulin resistance (fasting glucose x insulin / 405). Values <1.9 are normal; >2.9 indicates insulin resistance. TG/HDL ratio <2.5 is ideal. Both improve with exercise and reduced refined carbs.

Testosterone and CRP (inflammation marker). The T:C ratio (testosterone/cortisol) signals overtraining when it drops >30%. CRP <1.0 is low risk, 1–3 moderate, >3 high cardiovascular risk.

Snapshot of your latest cardiometabolic health across multiple axes. Each axis is normalized to 100 (best). Larger area = healthier profile. Track expansion over time as your biomarkers improve.

About Health Analytics

Computed indices: WHR, Navy BF%, BRI (Body Roundness), HOMA-IR (insulin resistance), TG/HDL, AIP (atherogenic index), CRI (Castelli risk), T:C ratio (overtraining). All calculated from your raw data — no manual input needed.

VAI (Visceral Adiposity Index) is automatically calculated when blood test data (triglycerides + HDL) is combined with your latest scan.
