What is BMI?

  • Body mass index (BMI) is a measure of body fat based on weight (weight) and height, to determine whether a healthy body weight is a healthy body weight for exercise.
  • Body mass index (BMI) is one of the criteria for determining the amount of excess weight because weight and height are used to determine whether a weight is healthy.
  • It should be noted that this test is often associated with total adiposity. It is an indicator of the amount of total body fat, and its height often indicates an increase in the percentage of total body fat.
  • It is noteworthy that the extent to which BMI values ​​are implicit is a measure of the effect of excess adiposity on the risk of disease and death, and therefore its height indicates a higher risk of developing obesity.
  • Health conditions associated with being overweight or obese: early death, heart disease, high blood pressure, degenerative arthritis, diabetes and some types of cancer.
  • It is noteworthy that the extent to which BMI values ​​are implicit is a measure of the effect of excess adiposity on the risk of disease and death, and therefore its height indicates a higher risk of developing obesity.
  • Health conditions associated with being overweight or obese: early death, heart disease, high blood pressure, degenerative arthritis, diabetes and some types of cancer.
  • BMI is also recommended for use in children and adolescents because it is measured in adults and the results are then compared to percentages.
  • Measuring BMI is one of the methods used by most health care providers.
  • Although it is a simple and inexpensive diagnostic method, it is not approved for testing because it requires additional testing by specialists to assess health risks. These tests include body fat percentage, fitness training, nutritional history and family health history.

How to Calculate BMI?

The formula for Body mass index (BMI) is body weight in kilograms divided by height in meters squared.

BMI Calculation

The BMI can be calculated by dividing the body weight in kilograms by the square of its height in meters (kg/m2) and the equation in metric units is as follows:

BMI = weight (in kilograms) ÷ (height (meters)) ²

For example, if a person’s weight is equal to 70 kilograms, and his height is equal to 1.75 meters, then his body mass index is calculated as follows:

BMI = 70 kg (1.75 m) ² = 22.9 kg / m²

BMI Results

The result of the BMI calculation indicates the ratio of weight to height; This code determines whether a person is underweight, or is healthy or overweight, or an overweight person is at high risk.

Ranges Of BMI

If your BMI is:

Below 18.5 – You are underweight.
Between 18.5 and 24.9 – in a healthy weight range.
25 to 29.9 – in the high load range.
Between 30 and 39.9 – you are in the obese category.
Body mass index is used to express weight separately for both sexes from age 20 onwards.

Note that BMI is not an accurate indicator of body fat levels, it may be the same for two different individuals, but one has a higher percentage of fat and the other has a higher percentage of muscle.

Furthermore, women have a higher percentage of body fat than men at the same body mass index, and the same applies to black men who have a lower percentage of fat than whites, while Asians Has a high percentage of fat. White.

People with higher muscle mass tend to have an obesity index, which is not associated with an increased risk of health problems.

Other methods used to determine body size include: waist-shoulder ratio and body composition. It calculates body fat and muscle mass.

These methods focus more on measuring the percentage of body fat and their distribution, so their use in conjunction with body mass index may contribute to improving the accuracy of estimating weight-related health risks.
