Since everyone is built differently, there is no such thing as an ideal weight, but it is possible to get an idea of a healthy weight range for your height by calculating your Body Mass Index(BMI). This can be done by dividing your weight by your (height in metres)2. Once you have calculated this If your score is below 18.5 you can be classified as 'underweight'. If it is between 19-25 your weight is within the 'normal, healthy weight' range. If you score between 25 and 30 you can be classified as overweight and if your score is over 30 you can be classified as obese.
Let's try an example: if you weigh 49kg with a height of 1.55m, then your BMI can be calculated as follows:
49kg
i.e.
49 =
_____
20.40 | 20.40 =
______
2.4025
| within a normal healthy weight range |
It is important to note that the BMI is only a guideline and is not applicable for pregnant women, very tall or short people, very muscular people, children and for people with certain medical conditions.
A strong relationship exists between BMI and risk of disease. People with a BMI of less than 25 have a low-average disease risk while those with a BMI above 40 have a higher risk.
