How To Lose Weight

BMI Calculator


This article provides in depth information on BMI Calculator.

The BMI calculator is used to measure Body Mass Index which refers to the body weight measurement according to height and weight of an individual. It reveals what the ideal or healthy weight for a person should be and hence is widely used as a barometer of obesity or weight issues amongst people.

How does it Work

Essentially, a BMI calculator automatically computes the BMI once the current weight and height are keyed in to the respective fields. The height can be measured in feet or centimeters while the weight can also be measured pounds or kilograms. Once the results are displayed, it is easy to estimate whether an individual falls into the underweight, normal, overweight or obese category. An underweight person would have a BMI less than 18.5 while a normal individual would have a BMI between 18.5 and 24.9. An overweight personís BMI would lie between 25 and 29.9 while an obese person would have a BMI equal to or above 30. Since the BMI calculation is done based on height and weight, it is relative. For example, a tall person weighing 132 lbs would be considered to be underweight, whereas the same weight on a shorter individual might qualify as being overweight or even bordering obese.

Risk Assessment

Being overweight revolves around three factors which would include the BMI, risk factors related to obesity and waist circumference. While the BMI calculator is always accurate, there could be some instances where body fat present in athletes could be overestimated especially since muscle can easily add up to weight. In the case of older persons, body fat can be underestimated since muscle mass is lost over the years. For persons with a high prevalence of abdominal fat, the risks of heart disease and cardiovascular problems are more. Persons with a BMI over 30, or between 25 and 29.9, need to seriously consider losing weight.

The Advantage

With a BMI calculator, it is easy to determine the healthy weight range required by an individual. Since this formula is standard and applicable across all ethnicities, ages and genders, it is very popular as a resource for measuring healthy weight ranges. Notwithstanding, BMI is the benchmark for assessing weight issues amongst individuals in medical facilities. Hence, it is easy to ascertain the baseline for specific conditions and health issues.

How to Customize BMI Readings

The BMI calculator is best used as a reference and a guide for losing weight. In some instances, the readings may need to be modified to suit certain ethnic groups, children or even athletes. For example, in the Indian, Chinese and Malaysian communities, a person with BMI over 23 would be overweight and a BMI over 27.5 would be considered as being obese. Similarly, for athletes, since there is more muscle mass, the BMI readings would be higher. In the case of children, body fat fluctuates throughout their growing years, and body fat proportions are also different in the case of boys and girls.

It is easy to assess if an individual is overweight, underweight or obese using a BMI calculator. A baseline for ideal weight range and instructional guidance makes it possible to arrive at the best route to losing weight and staying healthy.
