The short form of Body Mass Index is BMI. The Body Mass Index, provides clarification of a significant differentiation between being overweight or obese. If you weigh too much, you are obviously overweight. But if you have a very high quantity of body fat, then you are obese. Based on your body mass index, your doctor or other healthcare professional will list your weight as healthy, overweight, or obese.

According to the National Heart, Lung and Blood Institute (NHLBI), BMI sets out body weight relative to height and has correlation with total body fat content in most adults. In almost all cases, this means that the BMI will precisely reflect your weight and body fat proportion relying on your height and weight when sorting you as healthy, overweight, or obese.

The calculation of your approximate body mass index is relatively straightforward, although you’ll probably need a calculator just to save time. To get your BMI, follow the below steps.

**Step 1**: Multiply your weight in pounds by 703.

**Step 2**: Divide that result by your height in inches.

**Step 3**: Divide that result again by your height in inches.

For example, let’s say you weigh 200 pounds and are 6 feet 10 inches tall.

Multiply 200 by 703 to get 1,40,600. Then divide that by 82 (82 inches equals 6 ′ 10 ″) to get 1714.63. Now divide 1714.63 by 70 once more. The result 20.91 is your approximate BMI or Body Mass Index. If you don’t have a calculator handy, you can get the same result using the online BMI calculator tool. Just search BMI calculator is google search engine.

A BMI of 18.5 to 25 is considered healthy, 25 to 30 is classified as overweight, and 30 or more is obese. Therefore, the above example shows the BMI of a healthy personl.

As per NHLBI, the higher a person’s BMI, the greater the risk for health problems. Apart to causing your BMI to shoot up, surplus body fat is a well recognized health risk. Men and women with waist lines in excess of forty and thirty five inches, respectively, are much more at risk for health problems like high blood pressure, high cholesterol and type 2 diabetes.

The above rule has some exceptions. For example, body builders generally have a body mass index above twenty five and sometimes even above thirty. In this case, however, the higher BMI reveals the fact that body builders have added muscle mass without having added fat.

Finally, there’s still only one sure way to lower your BMI if you’re overweight or obese: Eat less and do more exercise. Your body will start burning more calories than you eat and your body mass index will go down over time.
