Body Mass Index (BMI) Calculator
You’ve probably heard of body mass index (BMI), but what does it really mean, and how is it connected to diabetes?
The Basics of BMI
Each body has its own unique size and shape. Body Mass Index (BMI) is a straightforward measurement that uses a person’s height and weight to determine a category. It’s calculated with the formula **BMI = kg/m²**, where *kg* represents weight in kilograms and *m²* is height in metres squared.
BMI isn’t a direct measure of body fat or overall health. People with the same BMI can have very different body compositions and fat distribution. It’s important to remember that BMI is just one of several tools healthcare professionals use to help assess the risk of potential health issues. Research shows that having a BMI outside the “normal” range, either higher or lower, can be linked to a greater likelihood of developing certain chronic conditions.
A person’s individual risk, combined with other assessments, helps guide health recommendations. Measuring waist circumference is also valuable, as carrying excess fat around the waist is strongly connected to increased health risks. In short, BMI on its own does not define how healthy you are.

Who is BMI for?
The BMI calculator applies to most adults 18-65 years old. It is less accurate for:
-
Muscle builders
-
Long-distance athletes
-
Pregnant individuals
-
Elderly populations
-
Young children
-
People with a physical disability
-
People of certain ethnicities
Why?
BMI doesn’t distinguish between muscle and fat. Individuals with higher muscle mass like athletes may have an elevated BMI without facing increased health risks. Conversely, those with lower muscle mass, such as growing children or older adults experiencing muscle loss, might have a lower BMI. Because body composition shifts during pregnancy and breastfeeding, BMI is not a suitable measure in these stages.
Diabetes and BMI
A BMI that is higher than the “normal” range is associated with a greater risk of developing type 2 diabetes and other long-term health issues, including heart disease, high blood pressure, and certain types of cancer. For individuals already living with diabetes, some treatments, such as insulin can make weight management more difficult, which may lead to a higher BMI.
When considered alongside other health measures, BMI can be a useful tool for identifying people who may benefit from obesity management. Consult your healthcare provider to determine the best approach for your individual needs.
Health risk classification according to body mass index
Classification | BMI category (kg/m2) | Risk of developing health problems |
|---|---|---|
Underweight | < 18.5 | Increased |
Normal Weight | 18.5 - 24.9 | Least |
Overweight | 25.0 - 29.9 | Increased |
Obese class I | 30.0 - 34.9 | High |
Obese class II | 35.0 - 39.9 | Very high |
Obese class III | >= 40.0 | Extremely high |
