Your Body Mass Index:
Body Mass Index (BMI) is a method used to estimate the fat percentage in a person’s body. The body mass index is calculated based on the ratio of a person’s height and weight. Based on the result of the body mass index, it can be determined how close or far a person’s current weight is from the ideal weight. To calculate the body mass index, the body weight is divided by the square of the height (kg/m²). The result is interpreted according to the following ranges:
  • Results below 18.5: Below ideal weight
  • Results between 18.5 and 24.9: At ideal weight
  • Results between 25 and 29.9: Above ideal weight
  • Results between 30 and 39.9: Significantly above ideal weight (obese)
  • Results above 40: Significantly above ideal weight (morbidly obese)

How to Interpret Body Mass Index Results?

Body mass index results provide a general idea about a person’s weight status. However, experts consider factors such as body fat percentage, waist circumference measurement, metabolic rate measurement, and detailed body analyses in addition to BMI when calculating ideal weight. Being above or below the ideal weight should be evaluated by a doctor in conjunction with other factors. It is important to consult a doctor for the resolution of health issues and prevention of potential health problems. In men, increased risk is considered when waist circumference exceeds 94 cm, and high risk is considered when it exceeds 102 cm. In women, increased risk is considered when waist circumference exceeds 80 cm, and high risk is considered when it exceeds 88 cm. In addition to body mass index, a detailed body mass index and obesity calculation can be performed by considering factors such as age, gender, body fat percentage, and waist circumference measurement. This calculation helps determine whether the weight, body fat percentage, and waist circumference are within normal values. It should be noted that accumulated fat in the body produces harmful hormones and excessive fat deposition, especially around the waist, can lead to various health problems. In addition to the BMI value, waist circumference measurement provides information about the degree of obesity. In adult men, body fat percentage is generally expected to be between 12-18%, while in women, it should be between 20-28%. If the body fat percentage exceeds 25% in men or 30% in women, it is associated with obesity.
