Hidden Fat Not Revealed by BMI

Although BMI calculates a simple obesity level, there is also hidden fat levels that is not revealed by a BMI designation.

The examples below show two cases that were revealed by OMRON’s research.

Although both cases are for people of almost the same height and weight, and their BMI designation is normal, the body fat percentage (p. 42) for case B is high.

That is, although case B has normal body weight, the actual fat level is high, revealing the “hidden fat”. This hidden fat indicates high levels of visceral fat (p. 43) 71664040-3C, even though the BMI designation is normal.
