InBody Body Composition Analyzer

Look Beyond the Number on the Scale

Your weight is only one measurement.

It doesn’t tell you how much of your body is muscle, fat or water—and it doesn’t show how those measurements are changing over time.

The InBody 580 Body Composition Analyzer provides detailed measurements that can help you better understand your body composition and track changes over time.

At Ontario Regenerative Medicine, we use body-composition information as one part of a broader approach to understanding your health.

Know more than your weight. Understand your body composition.

What Is Body Composition?

Body composition describes the different components that contribute to your total body weight.

Rather than looking only at the number on a conventional scale, body-composition analysis provides additional information about areas such as:

• skeletal muscle mass
• body fat mass
• percent body fat
• fat-free mass
• total body water
• segmental lean mass
• visceral fat estimates
• other body-composition measurements

This provides a more detailed picture of what makes up your weight.

Why Look Beyond Weight?

Two people can weigh exactly the same amount but have very different body compositions.

Even your own weight can remain relatively stable while your muscle and fat measurements change.

For example, changes in exercise, nutrition or lifestyle may be accompanied by changes in skeletal muscle or body fat that aren’t obvious from body weight alone.

That’s why tracking body composition can provide useful additional information.

The scale tells you how much you weigh.

Body composition helps show what that weight is made of.

Meet the InBody 580

The InBody 580 Body Composition Analyzer uses bioelectrical impedance analysis, or BIA, to estimate different components of body composition.

During the assessment, the device obtains measurements through contact with hand and foot electrodes.

The test is quick and non-invasive, and results are available immediately for review.

Your results can then be interpreted in the context of your individual health and goals.

What Does the InBody 580 Measure?

Weight

Your total body weight.

Unlike a conventional scale, however, InBody provides additional information about the components contributing to that weight.

Skeletal Muscle Mass

Skeletal Muscle Mass, or SMM, estimates the amount of skeletal muscle in your body.

Tracking SMM over time can be useful when you’re interested in understanding changes in muscle as part of your fitness, nutrition, body-composition or muscle-health goals.

Body Fat Mass

Body Fat Mass estimates the total amount of fat mass contributing to your body weight.

This measurement can be considered alongside skeletal muscle and other body-composition measurements.

Percent Body Fat

Percent Body Fat, or PBF, represents the proportion of your total body weight that is estimated to be body fat.

This provides information that body weight or BMI alone cannot provide.

BMI vs. Body Composition

The Same BMI Can Mean Very Different Things

Body Mass Index, or BMI, is calculated using height and weight.

Because BMI does not directly distinguish between muscle and fat, two people with the same BMI can have different body compositions.

Body-composition analysis adds information by estimating muscle mass, fat mass and other measurements.

BMI may still provide useful information in appropriate contexts, but it doesn’t tell the entire story.

Segmental Lean Analysis

Look at Different Areas of the Body

The InBody 580 provides segmental analysis of the:

• right arm
• left arm
• trunk
• right leg
• left leg

This allows you to see how estimated lean mass is distributed throughout different areas of your body.

It can also help identify differences between body segments that may be useful to consider when discussing fitness, training or muscle-health goals.

Understanding Muscle Balance

One benefit of segmental analysis is the ability to compare measurements between different parts of the body.

For example, there may be differences between the right and left sides or between the upper and lower body.

These measurements don’t diagnose the cause of an imbalance.

Instead, they provide objective information that can be considered alongside your health, activity level, training history and individual goals.

Body Water Analysis

Water is an important component of body composition.

The InBody 580 estimates:

Intracellular Water (ICW)
Water estimated to be located inside cells.

Extracellular Water (ECW)
Water estimated to be located outside cells.

Together, these contribute to Total Body Water (TBW).

The device also reports measurements related to the distribution of body water.

These measurements require appropriate interpretation and can be affected by multiple physiological and testing factors.

Visceral Fat

Understanding Fat Distribution

Body fat isn’t distributed uniformly throughout the body.

Visceral fat refers to fat located within the abdominal cavity around internal organs.

The InBody 580 provides an estimate related to visceral fat as part of its body-composition analysis.

This measurement can be considered alongside your other results and broader health information.

Fat-Free Mass

Fat-Free Mass, or FFM, represents the components of body weight other than fat.

This includes body water, protein, minerals and other lean tissues.

Tracking FFM alongside skeletal muscle and body fat can provide additional context when evaluating changes in body composition over time.

Basal Metabolic Rate

Understanding Your Estimated Energy Requirements

The InBody report includes an estimate of Basal Metabolic Rate, or BMR.

BMR represents the estimated amount of energy required to support basic physiological functions while at rest.

It should not be interpreted as the total number of calories a person should consume each day.

Daily energy requirements also depend on factors such as activity and individual circumstances.

Phase Angle

The InBody 580 provides a measurement called phase angle, which is derived from the resistance and reactance measurements obtained during bioelectrical impedance analysis.

Phase angle can provide additional information within body-composition analysis.

Like other InBody measurements, it should be interpreted in context rather than used on its own to diagnose a medical condition or determine someone’s overall health.

Track Changes Over Time

One Measurement Is a Snapshot. Multiple Measurements Show a Trend.

One of the most useful aspects of body-composition analysis is the ability to compare results over time.

Depending on your goals, repeat assessments may help track changes in measurements such as:

• skeletal muscle mass
• body fat mass
• percent body fat
• body water
• segmental lean mass
• visceral fat estimates

Your weight might change very little while the composition behind that number changes.

That’s why trends can sometimes provide more useful information than a single measurement.

Who Might Be Interested in Body Composition Analysis?

An InBody assessment may be useful for people interested in better understanding their body composition, including those focused on:

Muscle Health

Track skeletal muscle measurements and changes over time.

Fitness & Training

Add objective body-composition measurements to your fitness goals.

Nutrition

Better understand changes in muscle and fat alongside nutrition and lifestyle efforts.

Healthy Aging

Track muscle and body-composition measurements as part of a broader approach to health throughout adulthood.

Weight Management

Look beyond body weight alone by distinguishing between changes in estimated muscle and fat.

Baseline Assessment

Establish body-composition measurements that can be compared with future assessments.

InBody & Muscle Health at ORM

Muscle Matters

Body weight alone doesn’t tell you how much skeletal muscle you have.

The InBody 580 provides measurements of skeletal muscle mass and segmental lean mass that can contribute useful information to ORM’s broader muscle-health assessment.

If maintaining or understanding muscle is one of your priorities, these measurements can provide an objective starting point and a way to track changes over time.

InBody & Healthy Aging

Changes in body composition can occur throughout adulthood.

For people interested in healthy aging, understanding muscle mass, body fat and other body-composition measurements can provide additional information beyond body weight alone.

These measurements don’t define how “healthy” someone is by themselves.

Instead, they can be considered alongside medical history, physical activity, nutrition, laboratory information and other relevant health factors.

Understanding Your InBody Results

Don’t Focus on One Number

It’s tempting to look for a single “good” or “bad” result.

Body composition is more nuanced.

Your results may include several measurements that need to be considered together.

Factors such as hydration, recent exercise and testing conditions can also influence bioelectrical impedance measurements.

The most useful question isn’t simply:

“Is this number good?”

It’s:

“What do these measurements mean in the context of me?”
