Calculate your BMI

What’s a BMI calculator?

BMI stands for ‘body mass index’, and is a number generated by dividing your body weight by your height. A BMI calculator allows you to quickly figure out this number, giving you a general indication of whether your weight falls within a healthy range or not.

It is purely a guide as it gives quite a range of ideal weights.

How Accurate is BMI / Body Mass Index?

It’s certainly a handy tool if you think your weight is beginning to veer into the unhealthy category. However, BMI doesn’t take into account an individual’s levels of fat versus muscle, a key factor to be considered. So, while a BMI calculator gives a good indicator for obesity, it’s important to bear in mind that everyone’s body is different.

At our clinics we have a more accurate way of measuring your total body compositions. Our special Tanita scales measure both your body fat percentage and muscle percentage and also calculate your metabolic age and visceral fat.

BMI Classification Categories

BMI (kg/m2)Classification
Less than 18.5Underweight
18.5 - 24.9Normal - Healthy
25 - 29.9Overweight
30 - 34.9Obese
35 - 39.9Extremely obese
40+Morbid obese

Waist Circumference

Your waist circumference is also an accurate indicator of whether or not you are at risk of cardiovascular disease or type 2 diabetes. Carrying excess body fat around your middle is more of a health risk than if that weight is on your hips and thighs. Waist circumference is a better estimate of visceral fat, the dangerous internal fat that coats the organs.

For men, a waist circumference of 37 inches / 94 cm or more indicates an increased risk of chronic disease and a measurement of 40 inches / 102 cm centimetres or more indicates a higher increased risk of chronic disease.

For women, a waist circumference of 31 inches / 80 centimetres or more indicates an increased risk of chronic disease and a measurement of 34 inches / 88 centimetres or more indicates a higher increased risk of chronic disease.
