Calculating the Body Mass Index (BMI)
Body mass index calculation (BMI) is one of the easiest ways to learn if you are within the ideal weight or not.
Although as this method is a mathematical calculation, it has certain deficiencies, such as not taking into account the bone structure of the individual, muscle mass, or age.
Even though it is the most practical approach to assess the risk associated with obesity.
The formula for METERS and KILOGRAMS: WEIGHT (kilograms) between HEIGHTS (meters), a result between HEIGHTS (meters) again.
Example: 80kg / 1.75m / 1.75m = 26.12
The formula for POUNDS and INCH: WEIGHT (pounds) multiplied by 703 between HEIGHTS (inches), resulting from HEIGHTS (inches) again.
Example: 270lb * 703 / 68plg / 68plg = 41.0 BMI
Values:
Between the 18.5 Kg/m2: LOW WEIGHT.
Between 18.5 and 24.9 Kg/m2: IDEAL WEIGHT.
Between 25 and 29.9 Kg/m2: OVERWEIGHT.
Between 30 and 39.9 Kg/m2: OBESITY.
- More than 40 Kg/m2: MORBID OBESITY.
The body mass index is not always an accurate way to determine whether or not a person needs to lose weight. Here are a few exceptions:
- Body builders: because muscle weighs more than fat, people who are unusually muscular may have a high body mass index.
- Elderly: in old age, it is often better to have an index between 25
and 27 instead of an index below 25.
If a person, for example, is more than 65 years, a slightly higher body mass index may help protect against osteoporosis.
- Children: although a large number of children are obese, one should not use this index calculation to assess a child.
It is recommended to speak to a doctor about the appropriate weight at their age.
Exercise, regardless of BMI, can help reduce the risk of cardiovascular disease and diabetes, but you should always consult your doctor before starting an exercise program.
