A Complete Guide to BMI
Numerical value derived from a person’s weight and height, used to assess whether they are underweight, at a healthy weight, overweight, or obese. It is calculated by dividing weight in kilograms by the square of height in meters (kg/m²). While BMI is a simple screening tool, it does not directly measure body fat or account for muscle mass.
What is BMI?
Body Mass Index (BMI) is a numerical measure that helps determine whether a person’s weight is appropriate for their height. It is calculated by dividing a person’s weight in kilograms by the square of their height in meters (kg/m²). BMI is commonly used to classify individuals into categories such as underweight, normal weight, overweight, or obese, which helps identify potential health risks related to body weight.
How BMI Works?
BMI works as a general screening tool that estimates body fat levels based on height and weight. It provides a quick way to assess whether someone may be underweight or overweight, though it does not directly measure body fat or account for muscle mass, bone density, or fat distribution. Despite these limitations, it is widely used by healthcare professionals to identify possible health issues and guide further evaluations.
How to Maintain a Normal BMI?
Maintaining a normal BMI involves adopting a healthy lifestyle that balances diet and physical activity. Eating a nutritious diet with plenty of fruits, vegetables, whole grains, and lean proteins, while limiting processed foods and sugars, helps manage weight. Regular exercise, such as 30 minutes of moderate activity most days of the week, staying hydrated, getting adequate sleep, and managing stress are also essential for keeping BMI within the normal range (18.5–24.9).
