The following interpretations are demonstrated on the InBody770 Body Composition Result Sheet
but are applicable to all Result Sheets.

Click an output area to see its interpretation.

Body Composition Analysis

The InBody 770 shows the weight of intracellular water (ICW), extracellular water (ECW), fat free mass and body fat mass.

1) Intracellular Water, Extracellular Water and Total Body Water
The InBody 770 measures total body water (TBW) by using multiple frequencies to separate ICW and ECW. ICW reflects the amount of water within the cellular membrane and ECW is the amount of water in the interstitial fluid and blood. The sum of ECW and ICW is TBW.
2) Body Fat Mass
Subtract fat free mass from total body weight and you get body fat mass. Body fat mass is found under the skin or around organs. When an examinee’s fat mass is higher than the standard range, he/she is diagnosed as being obese. Monitoring the amount of body fat mass an individual has is critical to their health.
3) Fat Free Mass
Total body weight minus body fat mass leaves you with fat free mass. Athletic body types will have higher amounts of fat free mass compared to normal body types
4) Body Weight
The InBody 770 technology separates body weight into total body water, dry lean mass and body fat. Body weight is the total of these three components.

Muscle-Fat Analysis

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 segment, based on the examinee’s height. Therefore, an individual with a score of 100% is the average weight for their height.

1) Weight
The horizontal bar graph shows examinee’s current body weight in relation to the average weight for their height. The numbers next to the bar graphs indicate the examinee’s body weight. Average weight is based on the BMI Standard Weight Index.
2) Skeletal Muscle Mass
An individual with 100% skeletal muscle mass (SMM) has the average amount of muscle for someone their height. The normal range of SMM is 90-110% of the standard SMM.
3) Body Fat Mass
Body fat mass represents all the fat molecules an individual has in their body. A person with 100% body fat mass has the average amount of body fat mass.

Obesity Analysis

1) BMI
Body Mass Index (BMI) is used to determine obesity by using height and weight. BMI has been widely used in general medicine, dietary, and sports medicine fields as a means of diagnosing obesity. However, this method is flawed because it cannot be applied to adults with high levels of LBM, children, those over the age of 65 or pregnant females. Because BMI is commonly used in scientific research, it’s also included on InBody results sheets.
2) Percent Body Fat
The normal range for percent body fat (PBF) for males is 10-20% and 18-28% for females. People with a PBF greater than the range are regarded as obese or overweight. Individuals with a PBF that is below the range have low levels of body fat. Individuals with low levels of body fat can be separated into two categories. The first has muscle mass that is deemed appropriate for the individual’s body composition. The second has an inadequate amount of muscle mass in relation to their body composition, are considered unhealthy and have a higher possibility of contracting clinical diseases.
*PBF = Fat(lb) / Weight(lb) x100

Segmental Lean Analysis

There are two bar graphs for each body part in the Segmental Lean Analysis graph. This creates an effective and informed assessment of lean mass distribution.

The numbers beside the upper bar graph indicate the lean mass of the examinee in the designated segment. If the length of the upper bar graph reaches 100%, the examinee has the ideal lean mass for that segment based on his or her height. If the lower bar graph reaches 100%, the examinee has the ideal lean mass in relation to his or her current weight. Segmental Lean Analysis lets examinees see the distribution of their fat free mass. This helps professionals closely monitor changes and make adjustments as necessary.

ECW/TBW Analysis

Total body water is composed of intracellular water (ICW) and extracellular water (ECW). ECW is the water found in plasma, interstitial fluids, bone, cartilage, and dense connective tissues. ICW is the water found in the cytosol of every cell in the body.

In healthy individuals, intracellular fluid takes up roughly 62% of body water; extracellular fluid takes up the remaining 38% of body water. A healthy person’s ECW/TBW ratio is expected to fall between .360-.390. An ECW/TBW ratio above .390 may indicate the presence of a chronic health condition that may require medical attention or evaluation. ECW/TBW Analysis can detect unusual shifts in fluid distribution or changes in the ECW/ICW ratio.

Body Composition History

After an InBody Test is taken, results are saved onto the device and can be recalled if an ID is entered at the beginning of the test. Saved test results help track and monitor weight, fat free mass, PBF and, body fat mass. 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.

The cumulative graph quickly shows changes in the examinee’s body composition and allows for dietary-exercise modifications.

Visceral Fat Area

Visceral fat is the fat surrounding your organs. InBody devices provide an output for the amount of visceral fat area the examinee has. Higher amounts of visceral fat are associated with the development of diseases like diabetes, stroke and dementia. InBody recommends people maintain a Visceral Fat Level under 10 or a Visceral Fat Area under 100 square centimeters.

Segmental Fat Analysis

Segmental Fat Analysis is a derivative of the Segmental Lean Analysis and is presented in a similar manner. This portion of the result sheet provides the weight of fat in each segment and the percent above or below sufficiency.

Basal Metabolic Rate

The Basal Metabolic Rate (BMR) is the amount of calories a person needs to keep the body functioning while at rest. A person with more fat free mass would have a higher BMR than a person with less fat free mass.

Leg Lean Mass

InBody is able to provide Leg Lean Mass. This is important because Leg lean mass is the largest component of SMM and plays a significant role in disease/risk prevention. Providing a value for leg lean mass allows for a more personalized health care program.


TBW/Fat Free Mass (FFM) compares the density of an individual’s muscle s to the amount of water in their cells. This ratio can provide additional information regarding the health of the examinee.
TBW(l)/FFM(kg) * 100


Reactance is the opposition to a change in current or voltage. In BIA, reactance is used to measure phase angle.

Whole Body Phase Angle

Phase angle is an indicator of cellular integrity and intracellular water. InBody devices provide whole body phase angle and segmental phase angle at 50 kHz. Higher phase angles indicate greater cellular integrity and/or fluids inside the cells.

Results Interpretation QR Code

InBody provides a Results Interpretation QR code in the bottom right corner of the result sheet. This barcode provides the examinee with additional information about their Result Sheet. To access supplemental Result Sheet information simply scans the image with a QR code scanner.
