Question & Answer

Q1: What is a body composition analysis?

Body composition referes to the components of our body, and the sum of these subjects is the body weight.  A body composition analysis means to analyze what these components are.  Among many methods of analysis, the one used by the Inbody is the Bioelectrical Impedance Analysis (BIA), and divide the body into 4 components:  Total Body Water, Fat Free Mass, Protein and Minerals.

Q2: Is BIA accurate?

People have been very skeptical about BIA instrument and its results.  However, the Inbody has overcome the limitations that old BIA equipment has faced with its unique technology; multi-frequency, segmental analysis, 8-point tactile electrodes and no use of empirical estimation.

Q3: What can I do with an Inbody? How can I use it in my daily life?

Not only patients who suffer from edema, dialysis, or obesity need the Inbody.  The Inbody also can be used in other medical fields, and other industries such as sports, academic, nutrition, and much more.

Q4: Isn’t BMI enough to diagnose obesity?

The Body Mass Index is one of the well-known methods to diagnose obesity.  It is used to evaluate weight in relation to height.  According to BMI, however, athletes or muscular individuals would always be obese due to their heavy muscle.  Those sarcopenic (lack of muscle) with a great amount of fat would not be identified as being obese.  Therefore, for the true diagnosis of obesity, you need to check percent body fat with the Inbody.

Q5: What is the difference between Inbody and other body composition analyzers? What are major technical advantages of the Inbody compared to conventional BIA devices?

  • Direct segmental measurement including the trunk
  • Direct segmental measurement with the use of 8-point tactile electrodes.
  • Multi-frequency that measures Intracellular and Extracellular water separately.
  • No use of empirical estimations based on the population in the results: evaluation of actual body composition.

Q6: What is the difference between the models, which one is best for me?

It is not necessarily true that our new models supersede older models.  The Inbody series have a variety of functions and provided data.  Not everyone needs to use the most expensive model, Inbody720.  All of the Inbody will accurately measure weight and percent body fat and as it gets more expensive, data get expanded to for example, lean distribution each segment.

Q7: Why use the Inbody Tissues before testing? Do socks and shoes really need to be removed?

  • The Inbody Tissues increase electrical conductivity where the hand and feet electrodes make contact with the skin.  Without the Inbody Tissues, it could be difficult for the electrical currents to penetrate through severe calluses or hard skin on the hands or bottom of the feet.
  • Yes, it is important that the feet are bare and free from any socks, shoes, or stockings that may increase contact resistance of the electrical current penetrating at the contact points.

Q8: What affects measuring?

Changes in body composition reflect body status which may be affected by diseases, nutritional status and medications.  Hydration status also affects body water.  Accessories such as bracelet, necklace and watch may interfere with electrical conductivity.  As long as the conditions are kept the same every time, it will give consistent results.

Q9: Are there any types of people who should not be tested with the Inbody? Can pregnant women be tested? Can people with a pacemaker or any other medical implants be tested?

  • People with implanted defibrillators or pacemakers should not be tested.  Although a very low electrical signal is sent through the body, it may affect their functions.
  • Women at the period of menstruation will not get accurate results due to subtle changes in their body water.
  • Yes, those pregnant can be tested for their nutritional status, water balance and complications.  However, due to the changes in the mother’s body as in changes in water content, some of the results should not be interpreted as accurate.  Moreover, for they need to be precautious during the first three months of pregnancy, they should consult their physician prior to the test.
