What body composition metrics appear on page 2 of the Styku Summary Scan Report?

Overview

Page 2 of the Styku Summary Report displays the client's 3D scan alongside body composition metrics and circumference measurements. This article explains what each body composition metric means and why it matters for health.

Body Composition Metrics

Body Fat Percentage

The proportion of total body weight made up of fat tissue.

Calculated from fat mass — the total weight of fat tissue in the body.
Fat mass provides energy reserves, cushioning and insulation for vital organs, and helps regulate body temperature.
Health risk: Excess fat, especially in the abdominal region, is associated with increased risk of type 2 diabetes, heart disease, certain cancers, and reduced mobility and physical function.

Lean Mass Percentage

The proportion of total body weight made up of non-fat tissue, including muscle, bone, organs, and water.

Calculated from lean mass — the total weight of all non-fat tissue.
Supports healthy metabolism, physical activity, and protection against chronic disease.

Bone Mass Percentage

The proportion of bone mass located in the Android region (abdominal and thoracic areas) relative to total body weight.

There are no defined "good" or "bad" ranges for bone mass.
Monitor this value over time to ensure it is not decreasing.
Adequate bone mass reduces the risk of fractures, osteoporosis, and other bone-related conditions, and supports mobility as a person ages.

Android Mass

The amount of fat tissue stored in the upper body — specifically the abdominal and thoracic (chest) region.

Also referred to as abdominal or central obesity.
Considered a significant health risk due to its association with cardiometabolic diseases including type 2 diabetes and heart disease.
There are no defined "good" or "bad" ranges; lower values are better.

Gynoid Mass

The amount of fat tissue stored in the lower body — specifically the hips, thighs, and buttocks.

Considered a lower health risk than android mass.
Some cardiometabolic risk factors are still associated with excess fat in this region.

Visceral Fat

Fat that surrounds the internal organs inside the abdominal cavity.

Excess visceral fat secretes hormones and inflammatory molecules that negatively affect metabolism and cardiovascular health.
Associated with increased risk of type 2 diabetes, heart disease, and certain cancers.

Subcutaneous Fat

Fat that sits just beneath the skin.

Styku measures subcutaneous fat specifically in the android (stomach) region.
Like visceral fat, excess subcutaneous fat carries metabolic and cardiovascular health risks.
Clients with a larger waist circumference are likely to have higher visceral and subcutaneous fat values.
If both values increase over time, it indicates that fat in the abdominal area is increasing.

Notes

Bone mass has no "good" range — the key is tracking whether it stays stable or decreases over time.
Android and gynoid mass have no defined healthy ranges; trends over time and relative values are what matter clinically.
Visceral and subcutaneous fat values should be interpreted alongside waist circumference measurements for context.

If this resolves your issue, no further action is needed.

If the problem persists, contact support and include: the client's scan date, report page in question, and a screenshot of the metric displaying unexpected values.
