Healthy Weight Range Chart - Can BMI Be Trusted?

By Sam Jones


I am posting this article in response to a FAQ from my website. Many people are asking how they know if by being overweight they are putting their health at risk and what is being overweight? This got me looking into BMI, body Mass Index and the healthy weight chart.

When using the healthy weight chart as a means to determine if we are overweight we need to remember that this is a very broad and simplistic method.

The healthy weight chart or height weight chart can give a result that leaves some people confused.

Let me explain. These two tools are used as a basis for the calculation of the well known BMI measurement system for measuring Body Mass Index.

In recent times many people have questioned the accuracy of such a system that is based on such generalised personal information as height and weight and is constructed using comparative data that dates back 40 years.

The fact is that due to many changes in lifestyle and the modern diet this age old method may well be due for retirement. In some cases it has produced some very misleading results.

The height weight chart is used to give an approximation of whether you are within a healthy weight range.

The healthy weight range system is a collection of data from many thousands of people worldwide and is designed using an average of many different people's data.

For the vast majority of the population the height weight chart gives a realistic picture of where you are within the range of healthy weight.

So is the height weight chart a reliable indicator of healthy weight?

Be aware that these simple tools can produce some misleading results for some people:

Our subject who was over 6 feet in height was given a false assessment when using the methods discussed above. His physician has said he is at risk of fatty liver disease because of his accumulation of abdominal fat.

When fat is accumulated in the middle abdominal area it can increase the probability of fatty liver disease.

If you are quite a tall person and you have a large tummy, it is advisable you choose a healthy lifestyle in terms of dietary intake and exercise in order to significantly reduce abdominal fat.

To sum up: Due to known inaccuracies of the measurement systems for height to weight ratio, more doctors have now updated their advice to patients to be aware that carrying weight around the middle part of your body can put you at increased risk of diseases.
