Body Composition Analysis

Body weight is the sum of Total Body Water, Protein, Minerals, and Body Fat Mass. Maintain a balanced body composition to stay healthy.


Muscle-Fat Analysis

The Muscle-Fat Analysis uses bar graphs to provide a comparison between Weight, Skeletal Muscle Mass, and Body Fat Mass. The lengths of the bar graphs indicate the relationship between the current weight to the average value for that specific component, based on the examinee’s height. Therefore, an individual with a score of 100% indicates the individual is at the average value, calculated based on the average weight based on their height for that particular segment.

1) Weight
The horizontal bar graph helps to visualize the examinee’s current body weight in relation to the average weight. The numbers next to the bar graphs indicate the numerical values for that examinee’s body weight. Standard weight indicates the average value in accordance with the examinee’s height. The InBody provides the standard weight range, based on the BMI (Body Mass Index) Standard Weight Index.
2) Skeletal Muscle Mass
In comparison to the average weight, 100% Skeletal Muscle Mass indicates the examinee being measured has reached the average weight in Skeletal Muscle Mass. The normal range of SMM is 90-110% of the standard SMM. Change in skeletal muscle, as the result of increased exercise and diet modifications, is the most effective indicator of health improvements.
3) Body Fat Mass
Body Fat Mass represents all of the fat molecules an individual has in their body. 100% Body Fat Mass indicates the examinee being measured is at the average weight in Body Fat Mass, based on the examinee’s height. The average range of Body Fat Mass is established by calculating an examinee’s body fat mass and comparing it to the average total body weight and average Body Fat Mass.

Obesity Analysis

1) BMI
Body Mass Index (BMI) is an index used to determine obesity by using height and weight. The BMI method has been widely relied on in general medicine, dietary, and sports medicine fields as the main means of diagnosing obesity. However, this method is flawed in that it cannot be applied to adults with high levels of LBM, children, those over the age of 65, or pregnant females. Nevertheless, as BMI has been the most commonly used index, research using the BMI method to prevent adult diseases has been conducted frequently. This is why InBody also provides BMI-based information.
2) Percent Body Fat
The standard PBF is 15% for males and 23% for females, which are the respective midpoints of the standard ranges of Body Fat Mass in relation to standard weight: 10-20% of the standard weight for males and 18-28% for females. An individual with a calculated PBF that is greater than the standard range is regarded as having a high level of body fat. When an individual’s PBF is below the standard range, they are regarded as having a low level of body fat. Individuals with low levels of body fat can be separated into two categories. The first has muscle mass that is deemed an appropriate amount for that individual’s body composition. The second type has an inadequate amount of muscle mass in relation to their body composition. These individuals can be considered to be in an unhealthy state due to their imbalance of Body Fat Mass and Fat Free Mass, and these individuals have a higher possibility of contracting clinical diseases. 
*PBF(%) = Fat(kg) / Weight(kg) x100

Segmental Lean Analysis

There are two bar graphs for each body part in the Segmental Lean Analysis graph. The display of the two bar graphs allows for a more effective and informed assessment of the current distribution of the lean mass the examinee has. The two graphs have different meanings, respectively. 

The numbers beside the upper bar graph indicates the lean mass weight of the examinee in the designated segment. If the length of the upper bar graph reaches 100%, it indicates the examinee is at the ideal lean mass for that segment based on his or her ideal weight, derived from the examinee’s height. Therefore, the length of the upper bar graph shows the relative ratio of the ideal lean mass based on his or her ideal weight. Since the upper bar graph is based on the lean mass of the examinee’s ideal weight, the 100% value will not vary unless there is a change in his or her height. 

If the lower bar graph reaches 100%, it indicates the examinee is at the ideal lean mass in relation to his or her current weight. Therefore, the length of the lower bar graph indicates the relative ratio of the ideal lean mass for their current weight, while the number beside the lower bar graph shows that ratio. Since the lower bar graph is only based on the lean mass of the current weight, the 100% value will alter in accordance with weight change. Though it is not possible to check the increase or decrease of the lean mass as with the upper graph, the lower graph will directly reflect changes in the examinee’s weight, thereby allowing you to determine whether or not there is actual lean mass appropriate to his or her weight. Segmental Lean Analysis provides examinees with the ability to observe their upper/lower lean balance, left/right lean balance, and lean body mass distribution, segmentally. This allows for close monitoring of the distribution of lean body mass to help determine if the distribution of lean mass is adequate or if changes need to be made.


ECW Ratio Analysis

Total Body Water is composed of Intracellular Water and Extracellular Water. Extracellular Water (ECW) is the plasma water, interstitial water, transcellular water, and water found in bone, cartilage, and dense connective tissues. Intracellular Water (ICW) is the water found in the cytosol of every cell in the body.

A significant fraction of the human body is composed of body water. In diseased states the body water may be affected and become unbalanced. Body water is regulated by hormones, including the anti-diuretic hormone (ADH), aldosterone and atrial natriuretic peptide. In healthy individuals, intracellular fluid takes up roughly 62% of the body water, extracellular fluid takes up roughly 38% of the body water. Within the extracellular fluid, plasma takes up 1/5 of the extracellular fluid and interstitial fluid takes up 4/5 of the extracellular fluid. The ECW/TBW provided on the InBody770 allows for the monitoring of fluid distribution of the examinee. ECW/TBW can allow for the detection of unusual shifts in fluid distribution or changes in the Intracellular-Extracellular ratio. A healthy individual is expected to have a ratio of ICW to ECW is 3 to 2, which is 0.38 when calculated as ECW/TBW. To be considered within a normal range, an individual’s ECW/TBW ratio is expected to fall within 0.360-0.390.

If your ECW/TBW Ratio is above 0.390, this may indicate the presence of chronic health conditions that may require medical attention/evaluation.


Body Composition History

After an InBody Test is taken on the InBody770, the results will be saved onto the device only if an ID is entered at the beginning of the test. The saved test results allow for monitoring of weight, Skeletal Muscle Mass, Percentage of Body Fat and ECW/TBW. An individual measuring under the same ID will have their body composition results from the last 10 tests displayed on the bottom of the result sheet in a cumulative graph. 

Below the cumulative graph, it also has a data table. The cumulative graph helps for a quick and easy understanding of changes in the examinee’s body composition and current condition. The body composition history allows an individual beginning a variety of health treatment plans such as dietary-exercise modifications to monitor and track their progress. This allows for body composition changes to be monitored over time, taking into account where the individual started, the progress being made, changes in the overall body composition, and the ability to identify if modifications need to be made to the treatment plan based on the body composition history.


InBody Score

This score shows the evaluation of your body composition, which includes muscle, fat, and water in the body. And InBody score is an index used to help the examinee easily understand the state of his/her body composition.

70 or less : Weak Type / Obese Type
70~90: Normal, Healthy Type
90 or more: Strong Type


Visceral Fat Area

Visceral Fat is the fat surrounding your major organs. InBody provides an output of the amount of visceral fat area the examinee has. Because of the location of visceral fat, the amount of visceral fat the examinee has is associated with the risk of developing certain health diseases. An accumulation of visceral fat can contribute to increased risk of Insulin-Resistant Diabetes, Heart Disease, Stroke, and even Dementia. The accumulation of visceral fat has also been associated with technical difficulties in performing surgery, specifically abdominal surgery. It is recommended to maintain a Visceral Fat Level under 10 and a Visceral Fat Area of 100 or under to minimize health risks associated with excess visceral fat. Therefore, it is important to monitor the examinee’s visceral fat levels provided by InBody in order to properly assess that individual’s current chances of developing the mentioned health risks.


Weight Control

Weight Control provides the examinee a gauge that allows them to optimize the InBody Result for their dietary-exercise modification programs, allowing the examinee to make adjustments to the muscle mass-fat mass ratio rather than simply increasing or decreasing his/her weight. It explains to the examinee how to control his/her weight, especially by gaining or losing muscle or fat. 

Here, ‘+’ refers to the mass that must be increased, and ‘-’ refers to the mass which should be decreased. These numbers, a unique index offered only by InBody, indicate how many kilograms of Body Fat Mass should be lost / gained and how many kilograms of FFM(muscle) should be gained through exercise. Many people give up in the middle of the process of treating their obesity because their weight has not changed. In many cases, the reason is that FFM has increased as much as the amount of Body Fat Mass lost. However, as their actual weight has not changed at all, the effectiveness of the weight management program may be difficult to ascertain without the use of InBody technology. The InBody makes it possible for the examinee to see how much Body Fat Mass has been lost and how much FFM has been gained during the weight management program. Therefore, the InBody is a very useful device for identifying obesity, monitoring the weight management process, and facilitating the formation of a trust-based relationship between health professionals and their clients.


Segmental Fat Analysis

Segmental Fat Analysis is a derivative of the segmental lean analysis. This is presented on the results sheet as a segmental breakdown, similar to the segmental lean analysis. This portion of the result sheet provides both the weight value, as well as a percentage value. The segmental fat analysis evaluates whether the amount of fat is adequately distributed throughout the body, based on the examinee’s ideal body weight based on their height. Each bar shows fat mass in comparison to the ideal.


Research Parameters

Intracellular Water, Extracellular Water
Extracellular Water (ECW) is the plasma water, interstitial water, transcellular water, and water found in bone, cartilage and dense connective tissues. Intracellular Water (ICW) is the water found in the cytosol of every cell in the body.
Basal Metabolic Rate
The Basal Metabolic Rate (BMR) indicates the minimum energy required to sustain vital functions while at rest. The InBody uses the Cunningham equation to determine the BMR using a known regression equation based on the amount of FFM an individual has. FFM is known to be closely related to BMR. BMR is usually calculated using indirect Calorimetry, which measures oxygen demand. However, the InBody calculates BMR using Fat Free Mass. Therefore, should the examinee gain FFM during the weight management program, their BMR would also increase, which is a desirable result in any weight management program.
Waist-Hip Ratio
It is the ratio of waist circumference to hip circumference.
Body Cell Mass
This is the total mass of all cellular elements in the body, which constitutes all metabolically active tissues of the body.

Whole Body Phase Angle

Phase Angle is an indicator of cellular integrity and intracellular water. The InBody provides Whole Body Phase Angle and Segmental Phase Angle at 50 kHz. Higher Phase Angle indicates greater cellular integrity and/or fluids inside the cells.



Impedance is the frequency-dependent opposition of a conductor to the flow of an alternating electric current. Impedance is composed of two main properties, resistance and reactance. InBody provides segmental impedance values at varying frequencies to allow for accurate analysis of the human body. Since reactance is the interrupting force of alternating current flow, it increases in proportion to the integrity of cell membrane. Therefore, reactance and phase angle decrease when the number of cells is low or the cell membrane is more permeable or unhealthy.
