How It Works

BMI (Body Mass Index) is calculated by dividing your weight in kilograms by your height in meters squared. It's a simple screening tool to categorize your weight status and potential health risks.

Understanding Your Results

Underweight (BMI < 18.5)

May indicate malnutrition or health issues. Consult a healthcare provider.

Normal weight (BMI 18.5-24.9)

Indicates a healthy weight for your height.

Overweight (BMI 25-29.9)

May increase risk of health conditions. Consider lifestyle changes.

Obese (BMI ≥ 30)

Significantly increases health risks. Seek medical advice.

Limitations of BMI

While BMI is a useful screening tool, it has limitations:

  • Doesn't distinguish between muscle and fat
  • May not be accurate for athletes or elderly individuals
  • Doesn't account for bone density or body composition
  • Should be used alongside other health assessments

Frequently Asked Questions

Is BMI accurate?

BMI is a useful screening tool but not a diagnostic measure. It doesn't account for muscle mass, bone density, or body composition. Use it as one indicator alongside other health metrics.

How often should I check my BMI?

If you're monitoring weight changes, checking monthly or quarterly is sufficient. BMI is best used to track trends over time rather than daily fluctuations.

What should I do if my BMI is outside the normal range?

Consult with a healthcare provider who can assess your overall health, body composition, and provide personalized recommendations based on your individual circumstances.
