Body fat percentage
The degree to which a person is overweight is generally described by body mass index (BMI). Overweight is defined as a BMI of 25 or more, thus it includes pre-obesity defined as a BMI between 25 and 30 and obesity as defined by a BMI of 30 or more
[Pre obese and overweight however are often used interchangeably thus giving overweight a common definition of a BMI of between 25 -30. There are however several other common ways to measure the amount of adiposity or fat present in an individual’s body.
Body mass index
The body mass index (BMI) is a measure of a person’s weight taking into account their height. It is given by the formula: BMI equals a person’s weight (mass) in kilograms divided by the square of the person’s height in metres. The units therefore are kg/m2 but BMI measures are typically used and written without units.
BMI provides a significantly more accurate representation of body fat content than simply measuring a person’s weight. It is only mass.
