Body Mass Index Calculator (Height Weight Index Calculator)

Body mass index, also known as height and weight index; It is a calculation method that shows the estimated fat percentage in the body of people. The height-weight index is based on the person's height-weight ratio. According to the result of the calculation, the closeness and distance of the person's current weight to the ideal weight are calculated.

• Values below 18.5 kg/m²: Below ideal weight
• Values between 18.5 kg/m² and 24.9 kg/m²: At ideal weight
• Values between 25 kg/m² and 29.9 kg/m²: Above ideal weight
• Values between 30 kg/m² and 39.9 kg/m²: Well above ideal weight (obese)
• Values above 40 kg/m²: Well above the ideal weight (morbidly obese)

Meaning of Body Mass Index Results

While calculating the body mass index, factors such as fat ratio, body type, fat and muscle tissue are not included. Due to this situation, while calculating the ideal weight, besides the measurement of body mass index and waist circumference, more detailed information about the person's weight problem is obtained with the measurement of metabolic rate and detailed body analysis. Being under or over the person's required weight; should be evaluated by the physician along with other factors. In order to prevent existing health problems and possible health problems, it is necessary to act together with the physician.

If the waist area exceeds 94 cm in men, it is considered as increased risk, if it exceeds 102 cm, it is considered as high risk. In women, the risk increases when the waist circumference exceeds 80 cm and is considered high risk if it exceeds 88 cm.

Detailed Body Mass Index Calculation

While calculating obesity with a detailed body mass index, it can be learned whether the weight, body fat percentage and waist circumference are within normal values by taking into account the age and gender of the person.

In order to diagnose and treat obesity, first of all, it is necessary to know in which parts of the body the adipose tissue is collected. Adipose tissue accumulates in the body in two ways: apple type and pear type.

In apple type obesity, fat accumulates around the belly button. In pear type obesity, it accumulates in the hips and hips. However, it can be said that the fat collected around the belly is more risky and the risk of developing heart diseases is higher than the hips and hips.

What Is Important Other Than Body Mass Index in Calculating Obesity?

Fat accumulated in the body produces hormones that harm body health. Especially waist fat can cause many health problems. Waist circumference also gives information about obesity, as does body mass index.

In calculating obesity, the ratio of healthy muscle tissue to harmful adipose tissue is also taken into account. The body fat rate of an adult male is 25%; If it is over 30% in women, it is associated with obesity.

Height Weight Index Calculation for Children

Height and weight index in children and adolescents may vary depending on age and gender. The high fat rate seen in children's bodies causes weight-related diseases and serious health problems. On the other hand, the fact that children are underweight can also cause health problems. Children's height and weight tracking is done by pediatricians using percentile curves.

What Should a Normal Body Mass Index be?

A person's height-to-weight ratio of 18.5 to 24.9 is the ideal body mass index range. This range of values indicates that the person is at an ideal and healthy weight. It is recommended that people with this value maintain their current weight and continue to eat a regular, balanced and healthy diet.

What Should Body Mass Index Be According to Age?

Height and weight index varies according to age. The ideal body mass index reference ranges according to the age of the person are as follows;

• If you are between the ages of 19-24, the ideal reference range is 19-24 BMI.
• If you are between the ages of 25-34, the ratio of your weight to the square of your height should be in the range of 20-25 BMI.
• For those aged 35-44, the ideal height-to-weight ratio is 21-26 BMI.
• The body mass index for the 45-54 age range is 22-27 BMI.
• In people aged 55-64, the ratio of your ideal weight to the square of your height should be 23-28 BMI.
• The ideal value for the height-to-weight ratio for 65 years and older is 24-29 BMI.

How to Calculate Body Mass Index?

Body mass index, also known as height and weight index, is calculated by dividing the current body weight by the square of the height (kg/m²).
