Definition of BMI

BMI is the acronym for Body Mass Index, which is used to determine health and fitness.

Definition

BMI is considered an accurate measure of health and fitness since it factors in body fat, and takes into account one's height and weight.

How to Calculate BMI

BMI calculators are available online and require just one's height and weight. The actual mathematical equation for figuring BMI is:

BMI = (weight in pounds x 703) / (height in inches squared)

Understanding the BMI Table

Compare your BMI to the table below:
• Below 18.5 = underweight
• 18.5-24.9 = normal weight
• 25-29.9 = overweight
• 30 and above = extremely obese
It is important to note that someone can be considered to be overweight, but have little body fat, such as bodybuilders.

Significance

Studies have shown that both low and high BMIs are associated with health complications.

Improving your BMI

Decreasing body fat is the quickest way to improve BMI and improve general health. Improved eating habits and exercise are the quickest ways to decrease BMI.
