Body Mass Index (BMI) is an index used to estimate a person’s degree of obesity. It is calculated by dividing body mass (in kilograms) by the square of height (in meters). The equation for calculating BMI is:
BMI = weight(kg) / (height)2 (m2)
BMI is an index widely used by health professionals, such as doctors and dietitians, to assess whether a person is underweight, normal weight, overweight, or obese.
Body Mass Index is very useful as a tool for assessing physical health and the risk of diseases related to very low or increased body weight. High BMI levels may indicate that a person is overweight or obese, which is associated with chronic conditions such as diabetes, hyperlipidemia, hypertension, cardiovascular diseases, and certain types of cancer. On the other hand, low BMI levels may indicate being underweight or inadequate nutrition, which is also linked to health risks such as anemia and a weakened immune system.

The BMI categories are as follows:
- Below 18.5: Underweight
- 18.5 – 24.9: Normal Weight
- 25 – 29.9: Overweight
- 30 – 34.9: Obese (Class I)
- 35 – 39.9: Obese (Class II)
- 40 and above: Obese (Class III)
It is important to note that Body Mass Index does not take into account body fat percentage or fat distribution in the body, which are also important factors for health. For example, people with high levels of muscle mass may have a high BMI because of their muscle mass, not because of body fat.
For this reason, we use an important tool to accurately assess body composition: the body composition analyzer. At my dietetic office, I trust the InBody120 body composition analyzer for a detailed analysis of your body. Through body composition analysis, we can learn information about your body fat and its distribution, your muscle mass, body water, and more. Book your appointment today for an InBody120 body composition analysis and get 30% off! The offer is valid until 17/05!
Therefore, Body Mass Index is a useful tool for the initial assessment of a person’s body weight, but it should be combined with other measurements and evaluations for a complete assessment of physical health.
