What is a healthy body weight?
A healthy weight is the appropriate body weight for you. It is different for everyone and depends on your:
- muscle mass
- biological and genetic factors, including ethnic background.
Body mass index
Body mass index (BMI) is an internationally recognised standard to classify the body weight of adults. You can use your BMI to give you a rough indication of whether your are in a healthy weight range based on your height and weight.
The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared.
A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.
Although BMI is not a perfect measure, it is the most useful and valid for adults. BMI is not an appropriate measure for children, pregnant women and body builders. You should discuss your BMI with your doctor.
