The standard bathroom scale does one thing well. It tells you your total weight. What it cannot tell you is whether that weight is muscle, fat, water, or bone. That distinction is where your actual health story lives, and a body composition test is the tool designed to measure it.
At Craft Body Scan, we use InBody bioelectrical impedance analysis to produce that breakdown in about 45 seconds. Whether you are starting a fitness program, tracking a health condition, or establishing a baseline before a major lifestyle change, a body composition test gives you the numbers the scale was never built to show you.
What Is a Body Composition Test?
A body composition test is a health assessment that measures the percentages of fat, muscle, water, and bone in your body. Unlike weight alone, body composition gives you a complete picture of your physical health.
Two people can weigh exactly the same yet have very different health profiles. A 180-pound person carrying 40 percent body fat has a significantly different health risk profile than someone who weighs 180 pounds with 18 percent body fat and dense muscle mass. The number on the scale cannot show you that distinction. Body composition testing can.
I want to be precise about what that means in practice. Body composition testing does not replace your physician’s clinical assessment or bloodwork. What it adds is a precise measurement layer your doctor rarely has access to outside of a hospital setting. It gives you objective data about how your body is actually built, updated every time you retest.
What Does a Body Composition Test Measure?
A standard body composition test measures several interconnected components that together tell the story of your metabolic and physical health.
| Metric | What It Tells You |
|---|---|
| Skeletal Muscle Mass | The amount of muscle attached to your bones; a strong predictor of metabolism and long-term mobility |
| Body Fat Percentage | The fraction of your total weight that is fat tissue, broken into subcutaneous and visceral fat |
| Visceral Fat Level | Fat stored around your internal organs; elevated levels are associated with higher risk for metabolic disease |
| Total Body Water | Intracellular and extracellular fluid; imbalances can signal inflammation or chronic dehydration |
| Basal Metabolic Rate | Calories your body burns at rest; calculated from lean mass so the estimate is more precise than age-based formulas |
| Segmental Lean Analysis | Muscle and fat distribution broken down by body segment (left arm, right arm, trunk, left leg, right leg) |
Each of these metrics adds information that total weight cannot provide. Visceral fat, for example, is a meaningful indicator of metabolic stress even when someone’s overall weight looks normal on a standard scale.
Your InBody report includes reference ranges for each metric. The values below reflect widely used clinical benchmarks so you can read your results in context the moment the report prints.
| Category | Men (body fat %) | Women (body fat %) | Visceral fat score (InBody 1-20 scale) |
|---|---|---|---|
| Essential | 2-5% | 10-13% | 1-9 (Normal) |
| Athletic | 6-13% | 14-20% | 1-9 (Normal) |
| Fitness | 14-17% | 21-24% | 1-9 (Normal) |
| Acceptable | 18-24% | 25-31% | 10-14 (Elevated) |
| Elevated risk | 25%+ | 32%+ | 15-20 (High) |
How Does InBody Body Composition Testing Work at Craft Body Scan?
At Craft Body Scan, body composition testing uses InBody bioelectrical impedance analysis (BIA). The process is fast, non-invasive, and requires no radiation.
The appointment follows a simple sequence.
- You step onto the InBody device and hold the hand grips. The machine sends a safe, low-level electrical current through your body.
- The current travels at different speeds through fat, muscle, water, and bone because each type of tissue has a different electrical resistance.
- The device analyzes resistance data at multiple frequencies across all body segments and calculates your composition in real time.
- Your results print in about 45 seconds, giving you a detailed report you can read and keep.
A staff member walks you through your results so you understand each number before you leave. If you want to track changes over time, scheduling retests every 4 to 8 weeks makes trends clear and motivating.

Benefits of Body Composition Testing
Why body weight alone is not enough
Research from the National Heart, Lung, and Blood Institute shows that visceral fat accumulation significantly raises risk for cardiovascular disease and type 2 diabetes even in individuals with a normal BMI. A body composition test is the only practical way to detect elevated visceral fat without expensive medical imaging.
Patients schedule body composition testing at Craft Body Scan for six key reasons.
- Catch hidden risks early. Normal weight does not rule out high visceral fat, which is consistently linked to elevated metabolic and cardiovascular risk — risks that a scale or BMI cannot reveal.
- Set realistic fitness goals. When you know your current muscle mass and fat percentage, you can set targets grounded in your actual physiology rather than an arbitrary number on the scale.
- Track whether your program is working. Weight can stay flat for weeks while muscle builds and fat drops simultaneously. Retesting reveals the progress the scale hides.
- Personalize your nutrition approach. Your BMR from the test shows how many calories your lean mass actually burns at rest, which makes calorie targets far more accurate than standard online calculators.
- Identify muscle imbalances. The segmental lean analysis shows whether one side of your body carries significantly less muscle than the other, which can help you and your trainer address asymmetries before they turn into injuries.
- Create an objective health baseline. Before starting a new fitness program, medication, or lifestyle change, a body composition test gives you a documented starting point you can compare against future results.
Body Composition Test Methods Compared
Several methods exist for measuring body composition. They vary in cost, accessibility, and the type of data they provide.
| Method | How It Works | Typical Cost | Best For |
|---|---|---|---|
| InBody BIA | Multi-frequency electrical current through body segments | $35 | Routine tracking, fast results, detailed segmental data |
| DEXA Scan | Low-dose X-ray distinguishes fat, lean tissue, and bone | $75–$150 | Bone density plus body composition in a single session |
| Hydrostatic Weighing | Underwater weighing uses water displacement to estimate body density | $50–$100 | Research settings; requires full submersion |
| Bod Pod | Air displacement measures body volume and density | $45–$75 | No water required; less widely available |
| Skinfold Calipers | Manual pinch measurements at multiple body sites | $10–$40 | Budget-conscious; results vary significantly by technician skill |
| Smart Scales | Single-frequency BIA through feet only | $30–$100 one-time | Daily convenience; limited segmental data, less clinical validation |
Each method has tradeoffs. InBody BIA provides detailed segmental data without radiation and at a price point that makes regular retesting practical. If you also want to assess bone density, a DEXA scan measures both metrics in a single appointment.
How Accurate Is a Body Composition Test?
InBody BIA has been validated against reference methods in multiple clinical studies and is widely used in hospital, sports, and research settings. For most users, it delivers reliable and consistent results when test guidelines are followed.
Several factors affect accuracy across all BIA devices.
- Hydration level matters. Testing when dehydrated or immediately after a large meal can shift fluid readings and skew fat and lean mass estimates.
- Exercise timing matters. Heavy training within 12 hours before a test can cause temporary fluid shifts that affect your readings.
- Consistency across tests matters most. The most valuable data comes from retesting under the same conditions each time, which makes trend tracking reliable even if any single reading carries a small margin.
I want to be careful not to make these variables sound like flaws in the technology. The same factors affect DEXA, hydrostatic weighing, and every other body composition method in use today. The practical takeaway is that any body composition method rewards consistency in testing conditions over perfection in any single session.
The goal of body composition testing at Craft Body Scan is not a single perfect number. It is a consistent measurement system you use to track real, documented change over time.
How to Prepare for a Body Composition Test
Following these guidelines before your appointment gives you the most reliable starting measurement and ensures your retests stay comparable.
- Avoid eating or drinking for at least two hours before your test.
- Skip intense exercise in the 12 hours before your appointment.
- Stay well hydrated in the 24 hours leading up to your test, but avoid drinking large amounts immediately before.
- Remove shoes, socks, and heavy jewelry before stepping onto the device.
- Wear lightweight clothing or plan to remove heavier layers; light athletic wear works well.
- Avoid diuretics and alcohol in the 24 hours before your test, as both affect fluid levels.
- If you have a pacemaker or implanted electronic device, let staff know before testing. InBody BIA uses a mild electrical current that is safe for most people but warrants a quick check in these cases.
For retests aimed at tracking progress, test at roughly the same time of day under the same conditions as your baseline. That consistency makes your trend data meaningful.
How Often Should You Get Retested?
The right frequency depends on your goal.
- Active training or significant diet change: every 4 to 6 weeks. Changes in muscle and fat are detectable at this interval, and seeing measurable progress reinforces the habits driving it.
- Steady maintenance phase: every 8 to 12 weeks. Once you have reached your target body composition, quarterly retests confirm you are holding the results you worked for.
- Annual health baseline: once per year if you are not in a structured program. A yearly body composition test functions as an objective health snapshot alongside your other annual screenings.
Many Craft Body Scan clients pair a body composition test with a full body scan package to get a complete picture of internal health alongside their composition data.

Frequently Asked Questions
What is the difference between a body composition test and a BMI calculation?
BMI divides your weight by your height squared to produce a single number that places you in a broad category. It does not distinguish between fat and muscle, and it cannot detect high visceral fat in someone whose BMI looks normal. A body composition test directly measures fat mass, lean mass, water, and tissue distribution, giving you a far more detailed and actionable picture of your health.
Is a body composition test safe?
Yes. InBody bioelectrical impedance analysis uses a very low-level electrical current that is safe for nearly all adults. The current operates far below any threshold that would cause discomfort or harm. Individuals with implanted electronic devices such as pacemakers or cardiac defibrillators should consult their physician before testing as a standard precaution. There is no radiation exposure, no needles, no blood draw, and nothing you need to do beyond following the pre-test guidelines above.
How long does a body composition test take?
The test itself takes about 45 seconds once you are standing on the InBody device. From the time you check in to the time you leave with your printed report and a staff walkthrough of your numbers, most visits at Craft Body Scan take under 15 minutes total. You do not need to change clothes or do anything special on arrival beyond following the standard pre-test recommendations around food, exercise, and hydration.
Can a body composition test tell me if I have a health problem?
A body composition test is a measurement tool, not a diagnostic device. It shows your current levels of fat, muscle, water, and other compartments. That data can highlight areas worth discussing with your physician, but it does not constitute a clinical diagnosis. If your results show elevated visceral fat or a significant lean mass deficit, that information is worth bringing to your doctor. The test measures. Interpretation in a medical context belongs to a clinician.
What is a healthy body fat percentage?
Healthy ranges vary by sex and age. For adult men, body fat in the range of 10 to 20 percent is generally considered healthy. For adult women, 18 to 28 percent is a typical healthy range. Athletes often fall below these numbers while remaining healthy. Your InBody results include reference ranges so you can see exactly where your numbers fall.
Does hydration level affect body composition test results?
Yes. BIA measures how quickly an electrical current moves through your tissues, and water is a primary conductor. Testing while dehydrated or immediately after a large meal can temporarily shift your fluid readings. For the most consistent results, test at the same time of day and in the same hydration state each time you retest.
How is InBody BIA different from a smart scale at home?
Consumer smart scales use a single-frequency current that travels only through the lower body. InBody devices use multiple frequencies across all body segments, producing separate readings for each arm, leg, and the trunk. This segmental analysis is significantly more detailed and has been validated in clinical research in ways that consumer scales have not.
Do I need a doctor’s referral to get a body composition test at Craft Body Scan?
No referral is needed. You can schedule a test directly through our website or walk in to any Craft Body Scan location. Your results are yours to keep and share with your healthcare provider if you choose.
