Stahl Medical | Body Composition Analysis

Your Weight Isn't the Whole Story.
Your Body Composition Is.

The number on a scale tells you almost nothing meaningful about your health. Two people can weigh exactly the same and have completely different metabolic profiles, disease risks, and physical function - depending on how much of their body is muscle, fat, and visceral tissue.

SECA Technology

At Stahl Medical, we use hospital-grade SECA body composition technology to go far beyond weight and BMI, giving you a precise, clinically validated picture of what's actually happening inside your body. It's one of the most important health assessments you're not getting anywhere else.

Data That Drives Real Decisions

A body composition scan at Stahl Medical isn't a standalone number, it's a clinical data point that informs your entire care plan. Results are reviewed directly with our medical team and integrated into your weight management program, hormone optimization protocol, longevity plan, or athletic performance assessment. We track changes over time so you can see exactly how your body is responding to treatment, training, or lifestyle changes. This is the difference between managing your health and actually understanding it.

Body Composition Analysis

What Is Body Composition Analysis?

Body composition analysis measures what your body is actually made of, breaking down your total mass into fat, muscle, water, and visceral fat. This is done using a method called Bioelectrical Impedance Analysis (BIA), which sends a safe, imperceptible low-level electrical current through the body.

Because fat and muscle conduct electricity differently, the SECA device can precisely calculate the distribution of each tissue type throughout your entire body in under 30 seconds. The result is a clinically validated breakdown of your health that BMI and standard scales are completely unable to provide.

The SECA system has been shown to achieve 97% accuracy for muscle mass measurement and 98% accuracy for fat mass validated against whole-body MRI, the gold standard in body composition research.

Catch what BMI misses: identify hidden health risks like excess visceral fat that weight alone will never reveal

Track what's actually changing: measure real shifts in muscle and fat as your treatment plan progresses, not just pounds

What We Measure
And Why It Matters

Each metric we capture tells us something specific and actionable about your metabolic health, disease risk, and physical performance.

Fat & Muscle Distribution

Two people can weigh the same and have completely different health profiles. We measure both body fat and muscle mass together to reveal your true metabolic picture.

Visceral Fat

The dangerous fat surrounding your organs. Invisible to the eye and undetectable by a scale. Directly linked to heart disease, type 2 diabetes, and stroke.

Hydration & Body Water

Your fluid distribution across tissues impacts metabolism, cardiovascular performance, and recovery — a critical marker most health assessments miss entirely.

Frequently Asked Question

Get clear answers about body composition testing, what your results mean, and how this data can support your health, weight loss, and performance goals.

Is body composition analysis the same as a body fat scale at home?

No, it's significantly different. Consumer scales use single-point impedance with no clinical validation. The SECA system uses 8-point bioelectrical impedance analysis, measuring through both arms, both legs, and the torso simultaneously, with accuracy validated against whole-body MRI. The difference in precision and clinical reliability is substantial.

Does the scan hurt or involve radiation?

Neither. The scan is completely non-invasive and painless. The electrical current used is so low it is entirely imperceptible. There is no radiation involved whatsoever.

How long does the scan take?

The scan itself takes approximately 24 seconds. Your results are available immediately and will be reviewed with your provider during the same appointment.

Can I be "normal weight" but still have a dangerous amount of visceral fat?

Yes, and this is one of the most important things body composition analysis reveals. It is possible to have a normal BMI and still carry a high level of visceral fat - a condition sometimes called "skinny fat." This is precisely why weight and BMI alone are insufficient measures of metabolic health.

How does this connect to other services at Stahl Medical?

Body composition analysis is often used as a foundational data point across multiple programs, including weight management, hormone therapy, GLP-1 treatment, and longevity planning. Rather than treating metrics in isolation, our team uses your scan results as part of a comprehensive, integrated picture of your health.
