What is Body Mass Index?

On This Page (Contents)

The primary purpose of measuring Body Mass Index (BMI) is to determine an individual's ideal weight from a health perspective and to assess potential health risks. For people consulting a dietitian, this measurement is considered the first step in the weight management process. By evaluating the body mass index, a personalized nutrition and lifestyle program is prepared for the individual on the path to healthy weight loss. This approach helps the individual achieve both physical and mental health goals while also promoting informed steps in nutrition and weight control. This measurement assists in the following aspects:

  • Detection of Obesity and Overweight Conditions: Body mass index helps determine whether an individual's body weight is within a healthy range for their height. High BMI values may indicate being overweight or obese. 
  • Assessment of Health Risks: Individuals who are overweight and obese have a higher risk of developing various health problems, such as heart disease, type 2 diabetes, hypertension, certain types of cancer, and musculoskeletal issues. Body mass index allows for the early identification of such health risks. 
  • Treatment and Following: Body mass index provides a starting point for creating weight management and treatment plans for individuals. It also aids in evaluating an individual's progress during weight loss or gain monitoring. 
  • Public Health Research: In epidemiological studies, BMI is commonly used to assess the general health status of a population and obesity trends.

Despite the benefits of body mass index, it is important to understand that this measurement is not an absolute indicator of health for everyone. BMI does not take into account individual factors such as body fat percentage, muscle mass, bone density, gender, and ethnicity. Therefore, it is recommended that BMI results be used in conjunction with other measurements and clinical assessments when evaluating an individual's overall health status.

Calculate Your Body Mass Index

Body Mass Index (BMI), is a numerical value calculated by dividing a person's weight in kilograms by the square of their height in meters. BMI is a method used to evaluate the distribution of body weight relative to height in adult men and women. This index serves as an indicator to determine whether an individual is overweight, of normal weight, underweight, or obese. However, BMI values should not be considered an absolute criterion for everyone since they do not take into account individual differences in factors such as gender, age, muscle mass, and body fat distribution.         

BMI = kg/m2

 Body Mass Index (BMI) is simply calculated by dividing your weight in kilograms by the square of your height in meters. Here is a step-by-step easy explanation:

  • Calculate Your Height in Meters: First, if you know your height in centimeters (cm), you need to convert it to meters (m). To do this, divide your height by 100. For example, if you are 170 cm tall, dividing by 100 gives you 1.70 meters. 
  • Square Your Height: Next, multiply your height in meters by itself. So, if you are 1.70 meters tall, 1.70 x 1.70 = 2.89. 
  • Divide Your Weight by the Square of Your Height: Finally, divide your weight by the square of your height. Let's say you weigh 70 kilograms. In this case, divide 70 by 2.89. 70 / 2.89 = a BMI value of approximately 24.22.

How Do You Interpret Body Mass Index?

Body Mass Index (BMI) results are an indicator that shows whether a person's weight is healthy for their height. BMI values are generally used to determine whether an individual is underweight, of normal weight, overweight, or obese. Here are the BMI values and corresponding categories as defined by the World Health Organization (WHO):

Category BMI Range
Very underweight Below 16.0
Underweight 16.0 - 16.9
Mildly Underweight 17.0 - 18.4
Normal Weight 18.5 - 24.9
Overweight 25.0 - 29.9
Obese 30.0 - 34.9
Morbidly Obese 35.0 - 39.9
Extremely Obese 40.0 and above

These values are a general guideline for assessing an individual's body weight in terms of health. However, Body Mass Index (BMI) alone may not be sufficient for a comprehensive assessment of a health condition. Other factors such as body fat distribution and muscle mass, as well as the individual's overall health status, should also be considered.

For example, individuals with a high amount of muscle mass might show a high BMI, but this does not necessarily mean they have excess body fat. Similarly, older adults might have a BMI within the normal range but still have a high percentage of body fat. Therefore, it is important for BMI results to be evaluated by a health professional, alongside an individual's overall health status and other physical measurements.

What Should an Ideal Body Mass Index Be?

The Ideal Body Mass Index (BMI) generally indicates that an individual has an ideal and healthy body weight without carrying health risks. The World Health Organization (WHO) considers a BMI range of 18.5 to 24.9 as ideal for adults. This range shows that the individual is neither underweight nor overweight and has a balanced body weight without significant health risks.   

Recommendations for Maintaining a Healthy Body Mass Index

When the Normal Body Mass Index (BMI) range is between 18.5 and 24.9, it generally indicates a balanced body weight from a health perspective. Being in the normal BMI range suggests that many health risks are low, but you may need recommendations to maintain a healthy lifestyle and stay within this range. Here are some suggestions for maintaining a normal body mass index range:

  • Balanced Nutrition: Adopt a balanced diet that includes nutrient-rich foods such as fruits, vegetables, whole grains, lean protein sources, and healthy fats. Avoid processed foods, excessive sugar, and saturated fats. 
  • Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous aerobic activity per week if you do not have a specific health problem. Also, engage in muscle-strengthening exercises at least two days a week. 
  • Healthy Snacking: Opt for healthy alternatives like fruits, yogurt, or whole-grain products instead of high-calorie and low-nutrient snacks. 
  • Adequate Water Intake: Try to drink at least 8-10 glasses of water a day. Water is vital for your bodily functions and can help maintain a healthy body weight. 
  • Sleep Routine: Adequate and quality sleep is an important part of maintaining a healthy body weight. Aim for 7-9 hours of quality sleep per day. 
  • Stress Management: Stress can affect your eating behaviors and body weight. Try stress management techniques like meditation, deep breathing exercises, or yoga. 
  • Health Check-ups: Regular health check-ups and doctor visits can help you maintain a healthy body weight and diagnose potential health problems early. 

The items listed above will not only help maintain your body mass index but also be highly beneficial for your overall health status. If you wish to learn more about height measurement, you can follow our blog section.
