Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to both men and women. It is used as an indicator of overall health, with higher BMIs associated with increased risk for certain diseases such as heart disease, stroke, type 2 diabetes, and some cancers. Knowing your BMI can help you determine if you are at a healthy weight or need to make changes to improve your long-term health. In this article, we will discuss how to calculate your BMI and what it means for your health.
1. Determine Your Height and Weight
To calculate your BMI, you will need to know your height in meters (m) and weight in kilograms (kg). If you are measuring in feet and inches or pounds, you can use an online BMI calculator to convert the measurements. Also, be aware that the BMI formula does not take into account any special body characteristics, such as a pregnant woman or a bodybuilder with large muscles.
2. Use the BMI Formula
Once you have your measurements, calculate your BMI using the following formula:
BMI = weight (kg) / (height(m) x height (m))
For example, if you weigh 90 kg and are 1.75 m tall, your BMI would be:
BMI = 90 / (1.75 x 1.75) = 29.9

3. Interpret Your BMI Results
Once you have calculated your BMI, it is important to understand what the number means. According to the World Health Organization, a BMI below 18.5 is considered underweight, 18.5-24.9 is a healthy weight, 25-29.9 is overweight, and 30 or greater is obese. If your BMI falls into any of these categories, it can give you an indication of whether you should make lifestyle changes to maintain a healthy weight.
There are some BMI tips for seniors that you can follow to ensure that your BMI is in the healthy range for your age. Those include increasing physical activity, eating a balanced diet, and managing stress.
4. Consult a Doctor
If you are concerned about your BMI, consult your doctor. Your doctor can provide personalized advice and support to ensure that you are taking the necessary steps to maintain a healthy weight and reduce any health risks associated with higher BMIs. It is recommended that adults of all ages get their BMI checked annually as part of routine check-ups. In addition to calculating BMI, your doctor may also perform other diagnostic tests such as blood pressure, cholesterol, and glucose checks.
5. Make Lifestyle Changes

If your BMI is higher than 25, you should make lifestyle changes such as increasing physical activity, improving diet quality, and managing stress. Regular exercise can help to reduce body fat and improve overall health. Eating healthier foods such as fruits, vegetables, whole grains, lean proteins, and healthy fats can also help. Finally, managing stress levels is important as it can affect physical and mental health.
Body Mass Index (BMI) is an important indicator of overall health and can help you determine if your weight puts you at risk for certain diseases. Knowing how to calculate BMI and what it means for your health is essential in order to make lifestyle changes that will improve long-term health.
If you are concerned about your BMI, consult a doctor who can provide personalized advice on managing stress levels, increasing physical activity, eating healthier foods, and other strategies that may be necessary to reduce body fat and maintain a healthy weight. With the right knowledge and support system in place, anyone can take steps towards improving their overall well-being through healthier living habits.
