BMI measures whether a person is at risk of overweight disease. But is BMI a reliable tool? Read about how WW look at the matter.
What is BMI and what does it measure?
BMI is an abbreviation of Body Mass Index, and is a measure of weight-related health risk.
It is a tool that takes into account your weight in relation to your height in order to estimate the percentage of body fat. A high fat percentage is clearly associated with increased risk of certain diseases such as cardiovascular disease, hypertension, type 2 diabetes, respiratory problems and some cancers.
WW and Body Mass Index
Body Mass Index is a good tool for determining weight-related health risks. It is available to everyone because it only requires a simple mathematical calculation. The result is also easy to understand and interpret. It's considered to be amoungst the primary methods of measuring body fat, because other ways are often expensive and or difficult to access.
BMI is not always accurate
Of course there are times when BMI is not the best method. It does not take into account gender or age, nor to the amount of bone, muscles and organs in the body. Therefore, it is also not a crucial measure for certain groups, such as athletes and bodybuilders. For these people, it is more fair to use other methods that take into account the actual dimensions of the body. Many of these are quite demanding and you need to measure repeatedly to get a fair score.
