BMI (Body Mass Index) is a measurement of the body’s overall weight. It is a useful tool for determining whether or not someone is overweight or obese. BMI uses your height and weight to measure the appropriate body weight for each person. It is a reliable indicator to identify the risk of diseases associated with excess body fat. Some of the diseases linked with a high BMI include respiratory issues, gallstones, type 2 diabetes, high blood pressure, and heart disease.
BMI is a simple and inexpensive approach to determine your estimated level of body fat. You may use a number to determine if you’re at a healthy weight for your height and gender. The greater the number, the more body fat a person has in general. BMI is frequently used to determine whether your weight puts you at risk for health issues, including cancer, diabetes, and heart disease.

Limitations
The BMI provides a decent estimate of total body fat for most people, but it does not work for everyone. Bodybuilders and other muscular persons, for example, may have a high BMI due to their muscle mass, even if they are not overweight. In persons who have decreased muscular mass, such as some seniors, the BMI can underestimate body fat. Children and teenagers have the same BMI formula, but the number is interpreted differently depending on their age and gender.
How Is BMI Calculated?
The BMI is calculated by multiplying a person’s weight (using kilograms) with their height (using meters squared). This calculation will be done for you by our BMI calculator. The outcome will indicate the weight-group category you belong to.
- Underweight is defined as a BMI of less than 18.5 kg/m2.
- Normal weight is defined as a BMI of 18.5 to 24.9.
- Overweight is defined as a BMI of 25 to 29.9.
- Obesity is defined as a BMI of 30 or greater.
Interpretation of Results
BMI of 18.5 or less
You may need to gain weight if your BMI is less than 18.5 because you are underweight. It is suggested that you seek guidance from your doctor or a dietician.
A BMI of 18.5–24.9
You’re at a healthy weight for your height if your BMI is 18.5-24.9. You can reduce your chance of significant health problems by keeping a healthy weight.
A BMI of 25–29.9
You are mildly overweight if your BMI is between 25 and 29.9. For health reasons, you may be advised to lose weight. It is suggested that you seek guidance from your doctor or a dietician.

You are severely overweight if your BMI is greater than 30. If you do not lose weight, your health may be jeopardized. It is suggested that you seek guidance from your doctor or a dietician.
