HOW IT WORKS
BMI = weight(kg) / height(m)². Normal range: 18.5-24.9. This is a general indicator and doesn't account for muscle mass or body composition.
UNDERSTANDING YOUR BMI CATEGORY
Underweight (<18.5): May indicate malnutrition or underlying health issues. Consider consulting a healthcare provider.
Normal (18.5-24.9): Considered a healthy weight range for most adults, associated with lower health risks.
Overweight (25-29.9): Increased risk of cardiovascular disease and diabetes. Lifestyle changes may be beneficial.
Obese (30+): Significantly higher health risks. Medical consultation recommended for weight management strategies.
BMI LIMITATIONS & CONSIDERATIONS
Athletes & Bodybuilders: BMI doesn't distinguish between muscle and fat. A muscular person may have a high BMI but low body fat.
Age & Gender: BMI thresholds are the same for adults 20+, but health risks may vary by age and gender.
Ethnicity: Some populations (e.g., Asians) may have health risks at lower BMI levels. WHO recommends adjusted thresholds for Asian populations.
Body Composition: BMI doesn't measure body fat percentage, bone density, or muscle mass. Consider additional measurements like waist circumference.
Pregnancy: BMI is not applicable during pregnancy. Consult your healthcare provider for appropriate weight guidelines.
