What is BMI?

BMI, short for Body Mass Index, is a calculation used for adults to give a general indication whether your weight is healthy for your height. Created by the World Health Organization, BMI is calculated by dividing your weight in kilograms by your height in meters squared. This gives you a number, which can then be categorized within the BMI scale.

The BMI calculation cuts to the core of weight problems, and takes into account people of all shapes and sizes, for this reason, it has become a standardised measure of health the world over.

The BMI scale

The following BMI scale will tell you what your BMI says about your weight:

25 or less = Program FIT is best suited to this category.

25 – 30 = Program STEADY is best suited to this category.

30 or more = Program SLIM is best suited to this category.

The accuracy of BMI

When looking at your BMI, it is worth considering if you need to take other factors into account. For example, muscle weighs heavier than fat, so very muscular people, such as body builders, heavyweight boxers and other weight related athletes will likely find their BMI classes them as overweight to obese. If you fall into this category of athleticism, then chances are you have a good understanding of your health and weight, and BMI will be a poor and inaccurate measurement to use. If you are in doubt in this situation, consult a medical professional.

Another factor to take into account is whether you are pregnant. You should not use BMI as a measure if this is the case. In this situation, it is better to get advice from a midwife or doctor if you are concerned about your weight.

BMI is meant to be a general indication and tool for the general adult population. If you are not overly muscly, or pregnant, then BMI can be a good way to get an idea how healthy your weight is.
