Body Mass Index (BMI) is a simple calculation using your height and weight to estimate your body fat percentage.
-
How it’s calculated: BMI = Weight (kg) / Height (m)²
- Weight is measured in kilograms (kg)
- Height is measured in meters (m)
-
BMI Categories:
- Underweight: Below 18.5
- Normal weight: 18.5 – 24.9
- Overweight: 25 – 29.9
- Obesity: 30 or higher
Important Considerations:
- BMI is an estimate: It doesn’t directly measure body fat.
- Muscle mass can affect BMI: People with a lot of muscle mass may have a high BMI even with low body fat.
- Other factors matter: Consider waist circumference, body fat percentage, and overall health when assessing your weight.
