The body mass index calculator or BMI calculator determines whether a person’s health is at risk due to his or her weight. It is a ratio of your weight to your height.
There are many ways to determine if you’re at a healthy weight and BMI (body mass index) calculation is one of the easiest, simplest and most frequently used methods for the same. Determining your BMI is not difficult at all and you can do it easily even within the comfort of your home. In its simplest meanings, BMI compares a person’s weight to their height.
BMI calculator formula
BMI calculator uses a mathematical formula based on a person’s height and weight. BMI equals weight in kilograms divided by height in meters squared (BMI = kg/m2). When using pounds and inches, the formula needs to be altered slightly. Multiply your weight in pounds by 703 you can so calculate your own BMI accordingly. .
For example, if you weigh 120 pounds and are 5 ft. 3 in. (63 in.) tall:
BMI = 120 x 703 = 84,360 = 21.3
63 x 63 = 3,969
This is well within the healthy weight range.

In short, for most adults, the BMI calculator for men is a good way to get an idea of healthy weight ranges. But it is not always the final word in deciding if a person is overweight or obese. There are other things to think about when judging how much someone should’nt weigh. A person with a high BMI should be evaluated by a health care provider, who might use other factors such as skin fold thickness (a measure of body fat), waist size, evaluation of diet and family health problems, and other tests to find out if a person’s weight might pose a health risk. For example, you are at a higher risk if you carry most of your weight around the abdomen. If you are over weight, losing 5 to 10 per cent of your current body weight at a rate of 2 to 4 lbs (1 to 2 kg) per month is a healthy goal.
For someone who weighs 200 lbs (90 kg), 5 to 10 per cent is 10 to 20 lbs (4.5 to 9 kg).
It is important to remember that while BMI calculator for women does not show the difference between excess fat and muscle, it is closely associated with measures of body fat.
Therefore it is good practise to use alternative tools for a clearer health way.
Why do we need an alternative?

The risks of cardiovascular disease and tend to increase on a continuum with increasing BMI, type 2 diabetes but for practical purposes a person with a BMI of over 25 is considered overweight, while someone with a BMI of over 30 is obese. But one size does not fit all. In women, a BMI as low as 21 may be associated with the greatest protection from coronary heart disease death. The BMI for observed risk in different Asian populations varies from 22 to 25 kg / m2. Therefore, dieticians, nutritionists and weight loss experts believe that other methods should also be used to evaluate a person’s overall health risk and the associated grade of obesity.
Alternative to body mass index
There are two main and common alternative to body mass index:
1-Waist-hip ratio (pears”vs.”Apples”)
Health care providers are concerned not only with how much fat a person has, but so where the fat is located on the body. Women typically collect fat in their hips and buttocks, giving them a “pear” shape. Men usually build up fat around their bellies, giving them more of an “apple” shape. Of course some men are pear-shaped and some women become apple-shaped, especially after menopause. If you carry fat mainly around your waist, you are more likely to develop obesity-related health problems. Women with a waist measurement of more than 35 inches or men with a waist measurement of more than 40 inches have a higher health risk because of their fat distribution.
