Understanding Body Mass Index
What is BMI?
Body Mass Index (BMI) is a measure that uses your height and weight to work out if your weight is healthy. The BMI calculation divides an adult's weight in kilograms by their height in metres squared. This simple calculation provides a quick assessment of your weight category.
BMI Limitations
While BMI is a useful screening tool, it's not a diagnostic tool. BMI doesn't measure body fat directly, and it may not be accurate for all individuals, such as athletes with high muscle mass, pregnant women, elderly people, or children. It also doesn't account for muscle-to-fat ratio or bone density.
Health Consultation
For a complete health assessment, consult with a healthcare professional who can evaluate your overall health, body composition, lifestyle factors, and other important metrics beyond BMI. They can provide personalized advice for maintaining or achieving a healthy weight.
