Assessing Your Body… What is BMI?

What is BMITo better understand the problem of obesity, we need to first understand the clinical application of this term, including how obesity is determined.

What does “obese” actually mean?  The word “obese” means being so overweight it is detrimental to one’s health.   In clinical terms, obesity is determined by calculating the Body Mass Index (BMI) of an individual, based on his height and weight.  This can be done in either American Imperial units or, more traditionally, in metric units based upon mass (weight) in kilograms divided by height in meters squared.  A simple method for Americans to use is provided below:

In the United States using Imperial units:

BMI = mass (lb) x 703 ÷ height (inches)2.

BMI does not actually measure the percentage of body fat but it is an excellent resource for gauging the approximation of body fat an individual has, especially if that person has a more sedentary lifestyle.  To be considered obese, a person must have a BMI of at least 30.  “Seriously obese” refers to someone who has a BMI between 35 and 39 while “morbidly obese” is someone who has a BMI over 40.  None of these terms are used lightly.  Being referred to as obese should serve as a wake-up call to discuss with a medical professional a plan to lose weight.  On average, obesity reduces life expectancy by 6-7 years, “severe obesity” by ten years.  Approximately 12 million children are obese as well as 74.1 million adults.

To determine our level of “fitness” or “fatness”, we should all calculate our BMI.  Anyone with a BMI over 25 is overweight and should consider a weight loss program.  The higher the number is over 25, the more necessary it is to lose weight before we become another grim statistic.
