# How to calculate body mass index?

Body mass index is also known as height and weight index among people. The data obtained by dividing the weight in kilograms by the height gives you this number. By calculating your body mass index, you can facilitate your weight control, and if you realize that you need professional support, you can apply to experts. For a healthy life, you should note the changes in your BMI value at intervals and control your weight change.

## What is Body Mass Index?

The body mass index ranges used to calculate the weight status and whether the bodyweight is normal for height are standard. Worldwide, this table gives an idea about whether the person is overweight, normal weight or obese. However, this information alone is not sufficient to make a diagnosis. The ratio obtained does not constitute a definitive judgment as it does not provide any information about the fat-muscle balance and ignores other determinants such as ethnicity and age. It is still used to evaluate the population average weight to get an idea of ​​whether you are overweight or not. The number value in BMI can be found in the table, and data about the general weight status of the person can be obtained.

## Body Mass Index Calculator

The higher the value obtained due to the body mass index calculation, the higher the fat ratio can be estimated. Based on the BMI value, the health status of people, the risk of heart attack, the risk of developing diseases such as diabetes and cancer can be estimated. The calculation is the person’s weight in KG divided by the square of their height in meters. The obtained figure is compared with the body mass index table, and the weight category is determined.

The body mass index formula can be summarized as BMI = KG/mm. In exceptional cases, this calculation is not decisive when people gain muscle by doing very intense sports. Muscular people may have a high BMI because of their muscle mass, even if they are not very fat. Another exceptional group is the elderly. Since the body mass index does not include detailed parameters according to age, older people may be too fat due to low muscle mass, even if seen in the normal category. For this, they should be observed by experts and their fat and muscle mass should be determined.

The same formula is used for children and teenagers, but the result is not interpreted as adults. If the calculation is made for people between the ages of 2 and 18, the result does not promise a direct interpretation. Although two children have the same BMI value, one may be prone to obesity, and the other may be of normal weight due to their body structure. In these age groups, a dietitian or a pediatrician should make the evaluation.

Normal values ​​of the index vary with age.

• 19-24 Years: 19-24 BMI
• Ages 25-34: 20-25 BMI
• Ages 35-44: 21-26 BMI
• Ages 45-54: 22-27 BMI
• 55-64 Years: 23-28 BMI
• Age 65 and over: 24-29 BMI

## Meaning of Body Mass Index Value

The meanings of the values ​​obtained in BMI are as follows:

• 0-18.4: People are weak. Weight is considered insufficient for height. Weight gain is expected within the framework of the program to be prepared with the dietitian.
• 18.5-24.9: Normal value. People are at an ideal weight. It is recommended to have a regular, balanced and healthy diet and to include exercise in the routine of life.
• 25-29.9: Overweight value. People’s weight is higher than their height. In the company of a dietitian, studies should be carried out for people to lose weight, and plenty of sports should be recommended.
• 30-34.9: These people, who are considered obese, are in the range of obesity values. The weight of the people is at a level that may pose a risk. Weight loss is recommended.
• 35-44.9: Second-degree obese people are at risk of heart disease. People need to lose weight. In this regard, they must create a program together with the dietitian.
• 45+: People who are overweight are third-degree obese. These people, who have a very high risk of disease, should undergo health screening under the control of a doctor and dietitian and lose weight.
