The Body Mass Index (BMI)

Body Mass Index (BMI) is a numerical measure that estimates a person’s body fat based on their weight and height. It’s calculated by dividing your weight in kilograms by your height in meters squared. BMI helps categorize weight status into ranges such as underweight, normal weight, overweight, and obesity, which can indicate potential health risks. While it doesn’t directly measure body fat percentage or muscle mass, BMI is a useful, quick screening tool for assessing general health related to body weight. It's best used alongside other health assessments for a complete picture.
