Body Mass Index (BMI) is a widely used measure that assesses whether your weight is appropriate for your height. BMI guides you in setting weight-loss or weight-gain goals and helps you learn your healthy weight range. Defined by World Health Organization (WHO) standards, BMI is the most commonly used method for classifying weight status in adults.
Body Mass Index (BMI) is calculated by dividing your weight in kilograms by the square of your height in metres. BMI indicates whether you are underweight, normal weight, overweight, or obese. For adults, weight status is classified using the reference ranges set by the World Health Organization.
Body Mass Index (BMI) is calculated using your height and weight. The formula is very simple and anyone can apply it easily.
In this example the BMI is 24.22, which falls into the "Normal Weight" category. You can easily find your own BMI with our calculator above.
The table below shows the BMI classification set by the World Health Organization (WHO):
Once you know your BMI, you can follow the recommendations below to reach a healthy weight range and stay there:
Follow a balanced diet with vegetables, fruit, whole grains, protein, and healthy fats. Avoid excessive calorie intake.
Get at least 150 minutes of moderate physical activity a week. Activities such as walking, running, cycling, or swimming help with weight control.
Drink at least 2-2.5 litres of water a day. Water supports your metabolism and reduces unnecessary snack cravings.
Pay attention to portion sizes at meals. Using smaller plates and eating slowly increases the feeling of fullness.
Seven to eight hours of quality sleep a day protects hormone balance and supports weight control. Lack of sleep can raise hunger hormones.
Getting professional support from a dietitian while losing or gaining weight helps you reach your goals faster with a personalized program.
BMI is a general assessment tool for adults, but it may not give fully accurate results for everyone. It can be misleading for athletes with high muscle mass, pregnant women, and older adults in particular. In these cases, it should be evaluated together with body fat percentage, waist circumference, and other measurements.
No, BMI cannot distinguish between muscle mass and fat tissue. BMI only measures the relationship between weight and height. That is why athletes with high muscle mass can come out as overweight or obese by BMI even though their body fat percentage is low. Body composition analysis is needed to learn your muscle and fat ratios.
BMI calculation in children and adolescents differs from adults. For children, BMI is assessed using percentile curves by age and gender. The child's BMI is compared with the percentile values of children of the same age and gender. We recommend consulting a child health specialist or dietitian for BMI assessment in children.
BMI alone is not enough for a healthy assessment. Alongside BMI, factors such as waist circumference, body fat percentage, blood pressure, blood sugar, and cholesterol should also be evaluated. Waist circumference gives important information about visceral fat in particular. We recommend consulting a specialist for a comprehensive health assessment.
