Body Mass Index

Body Mass Index is an estimate of fitness and health based on basic body measurements. A Body Mass Index calculator is a method of suggesting what a persons' weight should be for a given height.

The Body Mass Index or BMI calculator should be treated as an indication, however, based on statistical generalities. The standard Body Mass Index calculator does not take account of a persons' gender, age or muscle development, how you will know whether your above average weight is due to your large tummy measurement, or your strong muscle development. Being overweight increases the risk of a wide range of diseases including heart disease and diabetes.

If you are worried about your weight, healthy eating and being physically active is the best way to bring it down and keep it down sensibly. If you calculate Body Mass Index it is one way of determining a target weight you should be aiming for, depending on your height.

Exercise and diet are the key parts of your life you need to control if you are to have good health and reduced weight. If either one is not controlled, it will be difficult to loose weight by diet or exercise alone. Simple changes to your normal diet will produce changes in your body weight. Fruit and vegetables are generally low fat, low calorie foods. So eating fruit and vegetables instead of foods that are high in fat and added sugars may help you achieve, or keep to, a healthy weight. Your Body Mass Index calculation will not change however if you eat fruit and vegetables in addition to your normal diet. You must greatly reduce bad foods.

Changing your diet is only one half of the process of changing your Body Mass Index calculation. You need to increase your exercise level to improve fitness. Exercise does not have to be formal or organised. In your daily life you can make policy decisions such as not using lifts or elevators, and walking more where there are reasonable distances. Walking does take time, but if you see it as part of your fitness lifestyle you won't feel you are 'wasting' the time.

The Body Mass Index calculator is a guide which suggests what weight is considered to be healthy for an individual, depending on their height. This can be used as a general target to aim for when exercising, and means that weight loss can happen in a controlled way. It is possible to loose too much weight too fast, and the Body Mass Index calculator suggests a sensible target range.

You can check whether you are a healthy weight if you calculate Body Mass Index (BMI). You do this by taking your weight (in kilograms) and dividing it by your height (in metres) squared. So, if you weigh 65 kilograms and are 1.73 metres tall, you would have a Body Mass Index BMI of 65/ (1.73 x 1.73) = 21.7.

A Body Mass Index over 25 is considered overweight, and over 30 is obese. Use some common sense when using this information. Muscle weighs more than fat, so if you are converting fat to muscle, especially at the start of a fitness program, you might not see much change in your weight. If your natural body shape is that of a big strong person, you probably find that the Body Mass Index calculator is a bit optimistic for you. Gender and age can also have an effect. In short, use the Body Mass Index calculator as a rough target and not a law or a stringent boundary you must not cross.
