Understanding Your BMI & Body Composition

Body Mass Index (BMI) is a standardized calculation used to estimate body fat based on your height and weight. While it does not measure body fat directly, our online BMI calculator serves as a vital screening tool to help you identify weight categories that may lead to health issues. Tracking your BMI is the first step toward managing your fitness goals and overall well-being.

The BMI Formula

BMI is calculated using the following metric formula:

$$BMI = \frac(weight(kg))(height(m) ^ 2)$$

WHO Standard BMI Categories

  • Underweight: BMI less than 18.5 — May indicate a need for a more calorie-dense diet.
  • Normal Weight: BMI 18.5 – 24.9 — Associated with the lowest risk of serious health conditions.
  • Overweight: BMI 25.0 – 29.9 — You may be at an increased risk of heart disease or hypertension.
  • Obese: BMI 30.0 or greater — Higher risk of Type 2 diabetes and other chronic illnesses.
  • Regular Monitoring: Use this tool to track your weight loss progress or muscle-building journey effectively.
