Frequently Asked Questions

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 calculation divides an adult's weight in kilograms by their height in metres squared.

Is BMI accurate for everyone?

BMI is a useful measure for most people over 18. However, it is only an estimate and doesn't take into account muscle mass, bone density, or body composition. For athletes or muscular individuals, BMI might not be an accurate indicator of health.
