Frequently Asked Questions
BMI (Body Mass Index) is a measure of body fat based on height and weight. It helps assess if you are underweight, normal weight, overweight, or obese.
BMI is calculated as: BMI = weight (kg) / (height (m))². For example, if you weigh 70 kg and are 1.75 m tall, your BMI = 70 / (1.75)² = 22.86.
A healthy BMI range is typically 18.5 to 24.9. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is obese.
BMI is a general indicator but may not be accurate for athletes with high muscle mass, pregnant women, or elderly people. Consult a healthcare professional for personalized assessment.
