BMI stands for Body Mass Index. It's a measure used to assess an individual's body weight relative to their height. It's calculated by dividing a person's weight in kilograms by their height in meters squared. The formula is:
BMI = weight (kg) / (height (m) * height (m))
BMI is commonly used as a screening tool to categorize individuals into different weight categories:
- Underweight: BMI less than 18.5
- Normal weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25 and 29.9
- Obesity: BMI 30 or higher
However, it's important to note that BMI is a simple and inexpensive method to estimate body fat, but it doesn't directly measure body fat percentage. As a result, it may not be accurate for everyone, especially individuals with a high muscle mass or certain health conditions. Therefore, it's often used in conjunction with other assessments to get a more comprehensive picture of an individual's health status.
