Detailed explanation of body mass index (BMI), including definition, formula, BMI table, and advice for achieving and maintaining a healthy BMI.
What is BMI (Body Mass Index)?
The term "BMI" refers to the Body Mass Index, which is a formula used to calculate an individual's percentage of body fat based on their height and weight. Finding out whether someone is underweight, normal weight, overweight, or obese can be done quickly and easily with this method. The body mass index (BMI) is commonly used as a screening tool for obesity-related health issues.
How is BMI Calculated?
BMI is calculated by dividing a person's weight in kilograms by their height in meters squared (BMI = kg/m^2). For example, if someone weighs 70 kilograms and is 1.75 meters tall, their BMI would be 22.9 (70 ÷ 1.75^2).

BMI can be interpreted using a table that takes into account a person's age and sex, as well as their BMI score. Here is a sample BMI table:
- BMI < 18.5 = Underweight
- BMI 18.5 - 24.9 = Normal Weight
- BMI 25 - 29.9 = Overweight
- BMI 30 - 34.9 = Obese (Class I)
- BMI 35 - 39.9 = Obese (Class II)
- BMI > 40 = Obese (Class III)
Body mass index (BMI) is not a foolproof indicator of health because it ignores other characteristics such as muscle mass, bone density, and body composition. Consequently, if you want an honest evaluation of your health, you should go to a doctor.
General Health Tips to Improve and Maintain BMI Score
Maintaining a healthy BMI is important for overall health and wellness. Here are some general tips to improve and maintain a healthy BMI score:
- Exercise regularly: Physical activity helps burn calories and maintain a healthy weight. Aim for at least 150 minutes of moderate-intensity exercise per week.
- Eat a healthy diet: A balanced diet that includes plenty of fruits, vegetables, whole grains, and lean protein can help you maintain a healthy weight.
- Monitor portion sizes: Overeating can contribute to weight gain. Use smaller plates, measure out portions, and avoid eating in front of the TV or computer.
- Get enough sleep: Lack of sleep can disrupt hormones that regulate appetite and metabolism, which can contribute to weight gain.
- Manage stress: Chronic stress can lead to overeating and weight gain. Find healthy ways to manage stress, such as meditation, yoga, or talking with a therapist.
By following these tips, you can improve and maintain a healthy BMI score and reduce your risk of weight-related health problems.
