Understanding Your Body Mass Index

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight, and obesity in adults. It is defined as weight in kilograms divided by the square of height in meters (kg/mΒ²).

⚠️ Limitations: BMI does not directly measure body fat. It may overestimate fat in athletes with high muscle mass or underestimate fat in older adults. Always consult a healthcare provider for a complete health assessment.
