BMI stands for Body Mass Index. It is a simple calculation using a person's height and weight. The formula is BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared.
For most adults, an ideal BMI is in the 18.5 to 24.9 range. A BMI below 18.5 is considered underweight, while a BMI of 25.0 to 29.9 is considered overweight.
BMI is a useful screening tool but it has limitations. It does not measure body fat directly and may not be accurate for athletes, pregnant women, or the elderly as it doesn't distinguish between muscle and fat.
It is good practice to check your BMI every few months or whenever you notice significant weight changes. However, focus on overall health indicators rather than just the number.
