Body Mass Index BMI
The BMI is more and more frequently being
used to determine whether or not a person is underweight,
normal weight, overweight or obese.
Arriving at the BMI involves
a mathematical formula:
BMI = (Weight in pounds /
height in inches squared) * 706
For example, a person
weighing 220 lbs and having a height of 5'7", would have a BMI
of:
[220 / (67*67)] * 705 =
34.6
Looking at the following
table
|
BMI
|
Category
|
| Less than 19 |
Underweight |
| Between 19 and
25 |
Normal |
| Between 26 and
29 |
Overweight |
| Between 30 and
40 |
Obese |
| Over 40 |
Morbidly Obese |
Shows us that a person having
a BMI of 34.6 would fall into the "Obese" category.
A much simpler way to calculate
BMI is to let our online calculator do the work. Just enter
your details and click "Calculate BMI". The results are rounded
but correspond to the table
categories.
The BMI is a
good indication as to your total body fat. For the majority of
people over 18 years of age, the results would be
valid.
There are some limitations
however in that the BMI can tend to overestimate results in
people with muscular physiques and underestimate results in
more mature age groups or people with less muscle
mass.
It is however a good starting
point to estimating your overall weight condition and can be
the necessary push you might need to start a healthier
lifestyle.
Above all it's important to remember that
starting out is usually the most difficult step. Over the
years I've helped numbers of people on the road to a
healthier and more attractive figure and body style.
Although we tend to concentrate on the physical aspects of
weight loss, the health benefits of achieving a normal
body weight far outweigh the aesthetic elements.
Being human though, we tend to place more
emphasis on the "look" rather then the "health".
Nobody can deny that some of the super
models at fashion shows look stunning under the lights of the
show. Get close to them though and look at their BMI and
the conclusion might well be different. I would be willing to
bet that many of the models we see on the TV or in magazines
are putting themselves at serious health risk through their
eating habits. Being underweight carries health risks which can
be as serious as those from being overweight. Achieving a
normal BMI range will also benefit our physical appearance, but
the health aspect must always come first.
