Assessing your weight

To avoid diseases associated with being overweight or underweight, you need to maintain your weight within the range considered normal for your height. To find out if you are within this range, you can use a height and weight chart such as the one shown below. You can also assess your weight by calculating your body mass index (BMI). To do this, divide your weight in kilograms by the square of your height in metres. A BMI figure under 20 indicates that you are underweight, while a figure over 25 shows that you are overweight.
