BMI Categories

The World Health Organization defines BMI categories as follows:

• Underweight: BMI less than 18.5
• Normal weight: BMI 18.5 to 24.9
• Overweight: BMI 25 to 29.9
• Obese: BMI 30 or greater

Why BMI Matters for Your Health

BMI is an important health indicator because:

• It helps assess your risk for weight-related health conditions
• Higher BMI is associated with increased risk of heart disease, diabetes, and certain cancers
• Low BMI may indicate malnutrition or other health issues
• It provides a starting point for discussions with your healthcare provider

Limitations of BMI

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

• It doesn't directly measure body fat
• It may overestimate body fat in muscular individuals
• It may underestimate body fat in older people who have lost muscle mass
• It doesn't account for differences in body composition between ethnic groups

For a complete health assessment, consult with your doctor who can consider additional factors like waist circumference, diet, physical activity, and family history.

Next Steps After Calculating Your BMI

Based on your BMI results:

• If you're in the underweight range, consider consulting a nutritionist
• If you're in the normal range, maintain your healthy habits
• If you're overweight or obese, small lifestyle changes can make a big difference

Remember that BMI is just one indicator of health. A balanced diet, regular exercise, and good sleep habits are all important components of overall wellness.
