Frequently Asked Questions

What is BMI?

BMI (Body Mass Index) is a measure that uses your height and weight to work out if your weight is healthy. It's calculated by dividing your weight in kilograms by your height in meters squared.

Why is BMI important?

BMI is a useful screening tool that can indicate whether you're underweight, at a healthy weight, overweight, or obese. It helps assess your risk for various health conditions related to weight.

How accurate is BMI?

While BMI is a useful general indicator, it doesn't distinguish between muscle and fat mass. Athletes or very muscular people may have a high BMI but low body fat. It's best used alongside other health assessments.
