BMI

BMI or Body Mass Index is a widely used method used to determine whether a person is of a healthy weight.  It is a calculation designed to assess how overweight (or underweight) a person might be relative to their height.

Weight

Height (m) x Height (m)

 

Adults should aim for a BMI between the 18.5- 24.9 range. The world health organisation WHO has recommended that the following categorise be used

BMI

Grade

<18.5

Underweight

18.5-25

Normal weight

>25-29.9

Overweight (Grade 1 obesity)

>30

Obese (Grade 2 obesity)

>40

Morbidly obese

 

There are groups of people who may not fall into these categories. These may include athletes as their body may be composed of more muscle than a person of the same weight that works in an office.  But BMI is a good point of reference.
