Understanding BMI
BMI (Body Mass Index) is a simple calculation that uses your height and weight to estimate body fat.
BMI Categories:
- Underweight: Below 18.5
- Normal weight: 18.5 - 24.9
- Overweight: 25.0 - 29.9
- Obese: 30.0 and above
Note: BMI is a screening tool and doesn't account for muscle mass, bone density, or body composition. Always consult healthcare professionals for personalized advice.
What is BMI and Why Does It Matter?
Body Mass Index (BMI) is a widely used screening tool that helps assess whether your weight is healthy for your height. It's calculated by dividing your weight in kilograms by the square of your height in meters.
While BMI is a useful general indicator of health, it has limitations. It doesn't distinguish between fat and muscle mass, so athletes with high muscle mass may have a high BMI despite being healthy. Similarly, older adults may have a normal BMI but still have excess body fat.
BMI is most useful as part of a comprehensive health assessment that includes other factors like waist circumference, body composition, and overall health markers. It's particularly valuable for identifying potential health risks and guiding weight management strategies.
