What does your InBody Result Sheet mean?

The InBody Result Sheet displays your body composition measurements in a clear, easy-to-read way to make understanding your results simple.

Below, you will find a concise breakdown of each section of the Result Sheet. You’ll learn what each measurement means, why it matters, and how it can help you be successful in your health journey.


Chapter 1:

Body Composition Analysis & Body Water

Body Composition Analysis

This section gives you a solid breakdown of your overall body composition, displaying these vital measurements in (lbs):

    • Total Body Water (divided into Intracellular and Extracellular Water)
    • Lean Body Mass
    • Dry Lean Mass
    • Body Fat Mass
    • Weight

Let’s take a closer look at how to interpret this section and use it to determine if you’ve gained muscle or spot fluid imbalances.

Body Composition Analysis & Body Water

Intracellular and Extracellular Water

At the top, you have Intracellular Water (body water inside cells) and Extracellular Water (body water outside cells), which make up Total Body Water.


Both ICW and ECW are valuable in their own right, but monitoring Extracellular Water, in particular, can provide deep insights. If you notice an increase in ECW, but not ICW, this could be due to acute inflammation from overtraining.
Dry Lean Mass

This value is the weight of the protein and mineral content in your body.


Because protein makes up most of your muscle, and Dry Lean Mass excludes body water, if your Dry Lean Mass increases, then this is generally a sign that you have gained muscle mass!

Body Composition Analysis & Body Water

Body Fat Mass

Below Dry Lean Mass is Body Fat Mass. This value reveals how much body fat, both surface level (subcutaneous) and internal (visceral), makes up your weight.

Displayed in the second column from the right, Lean Body Mass (LBM) is the sum of your ICW, ECW, and Dry Lean Mass. LBM is the weight of everything in your body except fat; for this reason, it is also called Fat-Free Mass. Lean Body Mass includes muscle, water, bones, and organs.


Usually, increases in LBM reflect an increase in muscle mass (which you can also see as an increase in Dry Lean Mass) and is considered an improvement in body composition. However, people who do not maintain normal body water ratios may have increased LBM due to swelling caused by strenuous exercise or activity.

Body Composition Analysis & Body Water

ECW/TBW Analysis

ECW/TBW is a measure of compartmental fluid distribution and shows, as a ratio, how much of your total body water is extracellular.

Taking multiple InBody Tests will establish your normal fluid status and help determine any imbalances. As a general guide, check to see that your ECW/TBW is below 0.390.


This graph lets you quickly understand if you have occasional inflammation or swelling in your body resulting from strenuous exercise or activity. You can also use this to give context to LBM. High LBM and a high ECW/TBW ratio usually indicate excess body water—not just muscle.

Chapter 2:

Muscle, Fat, & Obesity Risk

Muscle-Fat Analysis

This section shows how your Weight, Skeletal Muscle Mass, and Body Fat Mass compare to the healthy average range of people of the same height and sex. With Muscle-Fat Analysis, you get a better understanding of where your current body composition is so you can make any changes to get it to where you would like it to be.

Muscle-Fat Analysis is a favorite output for many people because it provides an easy-to-understand overview of body composition and helps narrow the focus of health goals.

Muscle-Fat Analysis has three components:
    This is your Total Body Weight.
    This is the total weight of your Skeletal Muscle Mass (SMM). SMM is muscle that can be grown and developed through exercise. Unlike Lean Body Mass, which includes everything except body fat, you can confidently interpret an increase in SMM as muscle gain.
    This is how much body fat you have (both the surface level and internal fat).

The Muscle-Fat Analysis also tells you whether you have a healthy balance of SMM and Body Fat Mass in respect to your weight.

Muscle, Fat, & Obesity Risk

How to read the numbers at the top

You can compare your measurements to others of the same height and sex with the percentages above the bar graphs. While the healthy range varies by output, the 100% mark indicates the healthy average for people of your height and sex. So if your Weight bar is at 130%, this would mean that your weight is 30% above average.

Similarly, if your Weight bar is at 70%, this would mean that you have 30% less mass than is considered the healthy average for your height.

How to find your body type using the C-I-D Method

Refer to your Muscle-Fat Analysis and connect the endpoints of each bar (Weight to SMM to Body Fat Mass) to form a C, I, or D.

Scroll down below to find out more about your body type!

Muscle, Fat, & Obesity Risk

“C-Shape” Body Type

If the length of the bar for your SMM is shorter than your Weight and Body Fat Mass, you have a C-shaped body type. Depending on where the measures are on the graph, this body shape can be characteristic of a person who is overweight, obese, underweight, or within the healthy range.


If you have a Muscle-Fat Analysis that looks like this, reduce your Body Fat Mass (which would also lower your Weight) and increase your Skeletal Muscle Mass. Ultimately, try to get your Body Fat Mass as close to the recommended range as possible and SMM as close to or above the recommended range.

Muscle, Fat, & Obesity Risk

“I-Shape” Body Type

If the length of the bars for your Weight, Skeletal Muscle Mass, and Body Fat Mass roughly form a straight line, you have an I-shaped body type.
Although people with this body type are often at a healthy weight or body fat percentage, there are still areas they can focus on to maintain or improve overall health.


Typically, if you have an I-shaped body type, you have a proportional muscle-fat balance. You are in a great position to focus on gaining muscle mass or reducing body fat to improve your overall physique.

Muscle, Fat, & Obesity Risk

“D-Shape” Body Type

If your SMM bar is longer than your Weight and Body Fat Mass, you have a D-shape body type. Usually, this is an “athletic” body type that many consider the ideal body composition shape. However, if the Weight and Body Fat Mass bars are above the recommended ranges, you should reduce your fat mass to get into the ideal range.


If you want to improve your strength and physique, you should monitor your SMM and Body Fat Mass bars to ensure that SMM increases without a significant increase in Body Fat Mass.


If your wish to lose body fat and become leaner, you should monitor your Body Fat Mass while making sure you do not lose too much SMM. If SMM losses become too significant, make the necessary adjustments to your strength training routine.

Muscle, Fat, & Obesity Risk

Obesity Analysis

This section displays your body fat percentage, or Percent Body Fat (PBF), and Body Mass Index (BMI), as well as the healthy ranges for these measurements.

Let’s explore how Obesity Analysis can give you a better idea of your current obesity level and your risk of related health conditions.

Body fat percentage is a division of your body fat mass by your total weight and a much better indicator of your risk of obesity than BMI.

Let’s take a closer look at why PBF is a superior metric for assessing your obesity and overall health risks.

Muscle, Fat, & Obesity Risk

Why you should focus on Body Fat Percentage over BMI

BMI is determined by dividing your weight by your height squared. BMI is just a single value that does not differentiate between fat or muscle mass. If you use BMI to track your fitness progress, you will never know if the changes were in fat or muscle.

BMI may also oversimplify health risks. Two people with the same height and weight would have the same BMI and health risks—even if one of them has a healthy amount of fat and high muscle mass.

On the other hand, PBF puts your weight into context by showing how much of it is fat mass. Tracking changes in your body fat percentage lets you focus on actual fat loss, not just weight loss, which can also come from muscle mass.


When assessing your current obesity level and the associated health risks, use Percent Body Fat (a.k.a. Body Fat Percentage) because it reveals how much of your weight is fat. BMI is a poor indicator of obesity risk but is on the Result Sheet for reference purposes

Muscle, Fat, & Obesity Risk

Healthy ranges for BMI and PBF

For BMI, 18.5 –24.99 kg/m2 is the healthy average range according to the World Health Organization. This healthy average range is presented on the Result Sheet, although the InBody device can be programmed to use a different range.

For PBF, the ranges differ for men and women, as women tend to carry more body fat than men due to their reproductive system and genetics. InBody calculates the recommended Body Fat Percentage ranges for men and women based on ACSM and ACE guidelines.

For men, the healthy range is between 10-20%.

For women, the healthy range is between 18-28%.

Body Composition History

This graph displays some of the most vital measurements from your previous tests (up to 8). With Body Composition History, you can easily spot trends and track your progress over time.

At the bottom of the Result Sheet is the Body Composition History graph, which automatically tracks your Weight, Skeletal Muscle Mass, Percent Body Fat, and ECW/TBW measures from recent tests.

The purpose of this graph is to let you monitor positive and negative changes in body composition so you can adjust your diet and exercise plan to get the results you desire.

Let’s examine how to track positive and negative body composition changes by looking at the example above. These results represent an athletic, D-shaped individual whose goal was to gain muscle and lose body fat.

Tracking positive change

The Body Composition History graph makes it easy to spot when positive body composition changes occur. For instance, a gradual increase in Skeletal Muscle Mass and decrease in Body Fat Mass over the past few tests indicates that you’ve made excellent progress towards improving your overall body composition.


By any measure, this indicates that you are on the right track to achieve your goals. You should continue to follow your diet and exercise routine and closely monitor your progress using Body Composition History.

Muscle, Fat, & Obesity Risk

Tracking negative change

The Body Composition History graph also makes it easier to spot negative body composition changes. For example, a drop in body weight may initially appear like a positive change, but regular testing may show that this trend was due to muscle loss, not fat loss.


A graph like this can be a real eye-opener because it shows that negative body composition changes can occur if your weight remains the same or even decreases for the wrong reason.
If your graph looks like this, you need to retain your muscle mass with some combination of nutrition and strength training.

Segmental Lean Analysis: Your Magnifying Glass

Segmental Lean Analysis

When used correctly, this is one of the most valuable sections of your InBody Result Sheet.

Segmental Lean Analysis displays your Lean Body Mass (Fat-Free Mass) in all body segments in pounds and its sufficiency to support your body weight as a percentage.

Interpreting your Segmental Lean Analysis can help you:

  • Spot areas for improvement
  • Assess if your Lean Body Mass is sufficiently developed in all body segments
  • Identify if you have any muscle imbalances

The InBody divides your body into five body segments: your arms, legs, and trunk (torso), or the area between your neck, arms, and legs. The data for each body segment is displayed as two bars.

Segmental Lean Analysis: Your Magnifying Glass


The top value shows how much Lean Body Mass (Fat-Free Mass) you have in pounds for each body segment.

Just like with the Muscle-Fat Analysis, the top bar of the Segmental Lean Analysis compares the pounds of Lean Body Mass against the average expected amount of Lean Body Mass for your height. You should always work to be at 100% or higher.


The bottom value compares your Lean Body Mass against your measured body weight, which helps you determine if you have enough Lean Body Mass to support your body weight, where 100% is sufficient.


Segmental Lean Analysis can help you see which area you need to increase your Lean Body Mass. Achieving a more balanced, healthy body composition may have other positive effects, such as body fat reduction.

Segmental Lean Analysis: Your Magnifying Glass


While any person can theoretically have an underdeveloped body segment, some groups may be at more risk than others. Here are a few populations who may have an elevated risk of having underdeveloped body segments:

1. Sedentary adults

Sedentary adults who do not exercise commonly have below-average Segmental Lean Mass typically in their legs, which may be due to having jobs that require sitting for long periods.

2. “Skinny Fat” individuals (sarcopenic obese)

People who are “skinny fat” have too much body fat and not enough muscle mass for optimal health. This muscle and fat imbalance can result in healthy body weight, often leading the person to believe that they do not need to make any changes.

3. The elderly

It is common for the elderly to have low Lean Body Mass due to their tendency to lose muscle due to decreased activity. Their ability to stay mobile as they age is impacted, putting them at greater risk of falling and breaking bones.

Segmental Lean Analysis: Your Magnifying Glass


Muscle imbalances are relatively common in today’s increasingly sedentary population. People who have jobs where they sit down for most of the day tend to have a developed upper body but an underdeveloped lower body.

Another imbalance the Segmental Lean Analysis can reveal is the imbalance between your right and left arms and/or legs. This type of muscle imbalance can be due to many reasons, including a workout routine that focuses on one side of the body over the other.


If you have an upper and lower muscle imbalance, increase your LBM in your lower legs to reduce your risk of injury. On the other hand, if one side of your body has more developed muscle mass than the other, optimize your strength training to achieve a better balanced LBM distribution.

Customizable Outputs

On the right-hand side of your Result Sheet, you will find a series of additional outputs. The InBody Test administrator can customize these outputs based on your specific goals.


This section makes it very easy for you to set health and fitness goals and help you achieve the recommended body fat percentage for your sex (15% for men, 23% for women).

Depending on your current Muscle-Fat balance, this Result Sheet output will recommend adjusting Body Fat Mass and/or LBM to reach the target PBF.
If you have too much Body Fat Mass, the InBody will advise losing a certain amount of fat mass and maintaining or increasing LBM. The InBody will never recommend losing LBM.


These recommendations are general guidelines for helping you achieve optimal health. However, you may have your own set of goals, so discuss them with your physician, personal trainer, or nutritionist before planning a routine for meeting those goals.

Customizable Outputs


In the example above, the person has 3.3 pounds of body fat in their left arm. For a person of their height and sex, that’s 158.9%, or 58.9% more body fat than the average person of the same height and sex.


You can use this section to track your body composition improvements and changes in body fat over time. While studies have shown that you can’t “spot target” body fat with exercise, you can use this section to get a more detailed account of your progress and stay motivated.

Customizable Outputs


The Basal Metabolic Rate, or BMR, is the calories you need for your basic essential functions. This value allows you to work with your dietician to create a nutritional plan, which is key to reaching your body composition goals.
You may think that your BMR is the calories you should eat in a day, but this is NOT the case. BMR does not take into account any calories needed to perform daily activities, and so your actual caloric need for the day is likely much higher than your BMR.

The graph looks a bit complicated but is actually quite simple to read. The “100” on the left side of the graph represents 100 cm2 of the visceral fat area.
Try to stay at or below this line to maintain a healthy fat balance.


Research has found that visceral fat is affected by cardiovascular exercise. Engage in more cardiovascular exercise to lose visceral fat and improve your health.
