What is BMI?
Body Mass Index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m².
How is BMI calculated?
BMI is calculated using the formula: BMI = weight(kg) / (height(m))². For those using imperial units, the formula is: BMI = (weight(lbs) * 703) / (height(in))².
Healthy BMI Range
A BMI of 18.5 to 24.9 is considered healthy for most adults. A BMI below 18.5 indicates underweight, 25-29.9 indicates overweight, and 30 or above indicates obesity.
Limitations of BMI
While BMI is a useful tool for identifying potential weight problems in adults, it has limitations. It doesn't account for factors like muscle mass, bone density, or body fat distribution. Athletes may have a high BMI due to muscle mass rather than body fat.
What to do with your BMI result
If your BMI falls outside the healthy range, consider consulting a healthcare professional for personalized advice. Remember that BMI is just one indicator of health and should be considered alongside other factors.
