Body Mass Index (BMI) is a common measurement that is used to help define your body weight. It is a standard measurement that applies to both sexes and is typically used by many medical professionals to determine whether your weight levels are healthy. Once a number has been established, it is compared to the BMI chart. There are several different BMI categories you could fall into. The four main ones include:
If your body weight is healthy, your BMI would fall between 18.5 and 24.9. However, you would be considered underweight if your BMI was 18.5 and below. If your BMI number is over 25, you would fall into the overweight category. Anything above 30 is classified as morbidly obese. If your number is over 30, you could be putting yourself at an increased risk of life-threatening illnesses associated with obesity.
The BMI calculator will not always give a perfect representation of your weight levels. For example, many bodybuilders, sports stars and athletes who have a lot of muscle mass will score high on the BMI scale, despite being healthy. Nonetheless, for the majority of other people, the scale is a suitable standard measurement to check whether you need to get into shape and lose weight.
Calculating your BMI is straightforward. Simply enter your height and weight below
To calculate your BMI, you have to divide your weight in kilograms by how tall you are in metres. Once you have the answer, divide it by the height again to work out your BMI. So for example, if your height came up to 1.7 metres tall and you weighed 71kg, you would have to divide 71 by 2.89 (1.7 x 1.7). The answer 24.56 would be your BMI score and this would mean you'd fit into the 'healthy' body weight category.
If your BMI is above the normal weight, then a few diet changes and an exercise regime may help to reduce it. However, if you are already on a diet and regularly exercising, then you may be suitable for Xenical, which is the only prescription weight loss treatment available in the UK.
