Your Styku scan is done. You’ve seen the 3D model on screen. Now you’re looking at a list of numbers — body fat percentage, lean mass, visceral fat score, waist-to-hip ratio, and measurements from head to toe — and you want to understand what they actually mean for your health and your goals.
This guide explains every major Styku metric, what the reference ranges are, what your results indicate, and what to do next. Your practitioner walks through these during your session — this is the reference you can come back to afterward.
Body fat percentage
Body fat percentage is the proportion of your total body weight that is fat tissue. It’s the most-discussed Styku metric because it tells you something your scale cannot: the composition of your weight, not just the total.
General healthy ranges
- Men: 10–20% is generally considered healthy; athletic range 6–13%; overfat above 25%
- Women: 18–28% is generally considered healthy; athletic range 14–20%; overfat above 32%
These ranges shift with age — a 55-year-old woman at 30% body fat is in a different category than a 30-year-old at the same number. Your practitioner applies age-specific context to your result.
Body fat percentage is a more meaningful health marker than weight alone because two people can weigh exactly the same and have drastically different body compositions — one carrying mostly lean muscle, the other carrying mostly fat. The metabolic and health implications are completely different.
Lean muscle mass
Lean mass is everything that isn’t fat — muscle, bone, organs, water. Styku estimates your total lean mass from the 3D model.
What lean mass tells you that body fat percentage doesn’t: it shows whether you’re losing fat, gaining muscle, or both over time. Someone who stays at the same weight but whose lean mass increases and fat mass decreases has made meaningful progress — but it looks like nothing on a regular scale.
Tracking lean mass over multiple Styku sessions is particularly useful when following a nutrition or training protocol, as it confirms whether body recomposition is actually happening.
Visceral fat score
Visceral fat is the fat stored around your internal organs — in the abdominal cavity, around the liver, intestines, and other organs. It’s metabolically active in ways that subcutaneous fat (under the skin) is not, and is strongly associated with:
- Insulin resistance and type 2 diabetes risk
- Cardiovascular disease risk
- Systemic inflammation
- Hormonal disruption
Styku estimates visceral fat from trunk and waist measurements. The score ranges from 1 to 30+.
Visceral fat score interpretation
- 1–9: Healthy range
- 10–14: Elevated — lifestyle focus warranted
- 15+: High — meaningful metabolic risk, worth discussing with a healthcare provider
Many clients are surprised by their visceral fat score. It doesn’t correlate reliably with how you look, your clothing size, or your total body weight. It’s common to find elevated visceral fat in clients who appear slim — which is exactly why measuring it matters.
Waist-to-hip ratio
Waist-to-hip ratio (WHR) is calculated automatically from your Styku scan measurements. It’s one of the oldest and most reliable predictors of cardiovascular risk — more predictive than BMI in many studies.
Reference ranges
- Men: Below 0.90 is healthy; 0.90–1.00 is elevated risk; above 1.00 is high risk
- Women: Below 0.85 is healthy; 0.85–0.90 is elevated risk; above 0.90 is high risk
Where you carry fat matters as much as how much you carry. People who carry more weight around their waist relative to their hips (apple-shaped distribution) have higher cardiovascular risk than those who carry more weight around their hips (pear-shaped). WHR captures this directly.
Posture analysis
Styku’s 3D model captures your posture alignment from the scan — shoulder tilt, hip tilt, head forward position, and spinal curvature. The posture report shows where asymmetries exist and how pronounced they are.
What posture data reveals that other tests don’t: structural imbalances that drive chronic pain, compensatory movement patterns, and asymmetrical muscle development. Clients with persistent shoulder, neck, or back pain frequently find that Styku identifies the structural issue that’s been contributing to it.
Posture findings are also useful for exercise programming — knowing you carry more weight on one side or have forward head posture helps prioritize which areas to address in strength and mobility work.
Circumference measurements
Styku automatically calculates over 400 circumference measurements from the 3D model — waist, hips, chest, thighs, upper arms, calves, and more. These measurements are precise, consistent, and don’t depend on how tightly a tape measure is held.
The most actionable measurements for most clients:
- Waist circumference — for metabolic risk; ideally below 35″ for women, 40″ for men
- Hip circumference — used with waist for WHR calculation
- Thigh and arm measurements — useful for tracking muscle development over time
How to track progress with Styku
Styku results are most useful as a series, not a single data point. Here’s what tracking over time tells you that a single scan can’t:
- Whether body fat is actually decreasing (vs just weight loss that includes muscle)
- Whether lean mass is increasing from training
- Whether visceral fat is responding to dietary and lifestyle changes
- Whether posture asymmetries are improving with targeted work
For most clients, rescanning every 8–12 weeks is enough time to see meaningful changes. Styku at MyThrivelytics is included in the OligoScan + Styku Combo ($220, Thrive Member rate $180). Repeat Styku sessions are available as part of the combo at the same price.
