Unlike Basal Metabolic Rate (BMR) Body Mass Index (BMI) is determined by an individual's height and body weight. It is widely used to determine whether the individual belongs to a healthy weight group. In simpler terms body mass index is the value that represents the weight status of human body in relation of the amount of fat present in it. Similar to Basal Metabolic Rate now it is also possible to easily calculate body mass index using BMI calculator for men and women. Similar to BMR calculator, body mass index calculators are simple tools those can be used for figuring out the amount of excess body fat present in one's body and also have a clear idea of the risks associated with this excess weight.
Body mass index is calculated depending upon the height and weight of an individual man and woman and can be broken down into four categories - underweight (BMI less than 18.5), normal (BMI between 18.5 and 24.9), overweight (BMI between 25 and 29.9) and obese (BMI is 30 or higher). According to researchers and experts these numbers are just fine as a general measurement of obesity for close to 95% of the population. But traditionally obesity has been defined as a certain cut off in the BMI scale and judging a person's obesity depending upon only his height and body weight, which is done by any BMI calculator for men and women is probably inadequate and not sufficiently efficient too. For people who are overweight but still maintain a good health - there body mass index doesn't properly reflect the health risks associated with their excess weight.
BMI and BMR calculator for both men and women are now widely used by doctors and health care professionals as quick screening tools but the BMI calculator for men that is now being widely used also has a number of possible drawbacks users are required to be aware about. One major drawback of both BMI and BMR calculators is the fact that they don't reveal anything regarding body composition like the amount of muscle and fat present in the body. This is a reason that conclusions based upon the results of these calculators might not always be accurate and also misleading in certain situations. People like players or body builders whose weights are pushed up by their muscle tissues have body mass index that is pretty high but they also have only little body fat. Activity level of the concerned individual, body type and location of fat in the body, age and ethnicity are other factors those should also be playing determining role in Basal Metabolic Rate and body mass index calculation but the current calculators those are now being offered online don't involves this factors in their calculations and that is precisely the reason that the results they show are only accurate up to a certain standard and it might not be a very good idea to fully depend upon them.
