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.
In my article I explain the differences between the different methods of calculating the healthy weight range of an individual using the healthy weight chart.
There are several names for the healthy weight chart, some refer to it as the height weight chart but is essentially the same thing.
These charts work on a very similar way to the more modern BMI scale of calculating your 'healthy weight' based on some mathematics to produce a height to weight ratio.
If you are not familiar with these charts you may well have seen one pinned to your doctor's wall in his surgery, but this method of calculating healthy body mass is not without its critics.
The problem is that some people especially those who are taller than the average person, can be given a false sense of security when using the height weight chart as a measure of healthy weight.
The height weight chart is used to give an approximation of whether you are within a healthy weight range.
Healthy weight range like many other similar systems is designed by taking in information from many sources of population data and averaging it out to produce the system.
Because the height weight chart is predicated on data from so many people it is usually fairly accurate and gives you an idea of where you fit in a wide band range of healthy weight.
Because of the generalised nature of these tools you should always look at other factors besides the height weight chart to be confident in the accuracy of your result.
Caution, there are cases where the results have been incorrect for example:
We found that a taller than average man who was considered to be in the healthy weight range had developed some liver function problems.
When fat is accumulated in the middle abdominal area it can increase the probability of fatty liver disease.
So if you are a tall person who tends to carry weight around the middle of your body you should ask your doctor for advice, and NOT rely on BMI as a measure of your healthy weight.
Conclusion: Instead of relying on a generalised BMI healthy weight system you should pay attention to fat distribution in the abdominal region and also overall body fat percentage as a more accurate and personalised approach to determining healthy weight.
