body mass index calculator with age and gender

In adults, body mass index considers weight and height only. The BMI calculation is different when it comes to children and teenagers. It’s not just weight and height, and the healthiest weight range equally depends on gender, age, ethnicity, body fat distribution, and body frame. The optimum weight for men and women is not solely dependent on BMI calculations. Therefore, most health experts recommend a BMI at or above 18.5 as ideal. In addition, BMI can categorise you as overweight or obesity, even when you’re in better shape. On the other hand, if you’re athletic, it is likely to have a BMI score greater than 25 due to greater muscle mass. There are, indeed, healthy individuals with BMI values in the 25 to 29 range. It makes you more prone to multiple health problems like heart disease, blood pressure, diabetes, and stroke.įor most people, the ideal BMI range is between 18.5 and 24.9. If your BMI is 30 or more than 30, it shows that you’re in the obese range.To put it simply, the higher spectrum of the range indicates nearing obesity. A BMI between 25 and 29.9 is the overweight range.

A BMI value between 18.5 to 24.9 indicates that you’re in the healthy weight range.

People within this BMI range must put on weight to avoid further health complications. It indicates a high risk of malnutrition.

If your BMI is under 18.5, you’re considered underweight.

So, the imperial formula for BMI calculation is:įor example, if your weight is 150 pounds and your height in inches is 65, then according to the formula, your BMI will be 24.96. The resulting value should then be multiplied by 703 and round to one decimal place. First, the weight in pounds should be divided by height in inches squared. In addition to the metric formula, you can also find BMI using the imperial unit formula. Or the mathematical equation terms are as follows īMI = weight (kg)/square of the height (m2)įor example, if your weight is 75kg and your height in metres is 1.75, then according to the formula, your BMI will be 24.5. As per the formula, you get BMI by dividing your weight in kilograms by the square of your height in metres. However, BMI can get manually calculated with the help of a mathematical formula. BMI calculators are available online, which give you instant results after entering your age, weight, height, and sometimes, gender. The body mass index is a simple and inexpensive calculation method using your height and weight. As a result, men and women can have the same BMI readings but different fat percentages. Thus, muscular people can be of healthy weight even though their BMI range falls in the obese category.Īnother problem is that it doesn’t take into account gender differences. For example, the high BMI reading of weight trainers and athletes show as overweight or obese, even when they’re not. Since muscle tissue is more dense than fat, the density and distribution do not reflect in BMI calculation.

Also, it does not consider body fat percentage, muscle mass, or body fat distribution, which produces an inaccurate BMI reading.īMI measure cannot distinguish between fat and muscle. Demography plays a role in determining optimum body weight. It considered data involving Europeans to determine the range. The first problem is that BMI as a measure is not representative of all demographics. Therefore, you cannot consider it a diagnostic tool for body fat percentage.ĭespite being used since the 1840s, the concept of Body Mass Index has some drawbacks. However, BMI fails to tell if your overall weight is water, muscle, or fat. The higher your BMI, the more overweight you are. In simple terms, your BMI range estimates your total body fat based on overall weight and height. It is more of an indicator to determine if the weight is healthy and compatible for a particular height. What is BMI?īody Mass Index or BMI is a body size measurement concerning your weight and height. There are multiple alternatives to BMI for providing reliable information on how much body fat you are carrying. BMI is widely used today in healthcare settings to flag potential weight-related health issues or track the chances of obesity. It takes into account your height and weight to show whether you’re underweight, average weight, overweight, or obese. The body mass index (BMI) is a convenient guide for evaluating a healthy weight range.
