What is BMI?
Body Mass Index (BMI) is a simple calculation using your height and weight to estimate body fat. While it doesn't directly measure body fat, it's a useful screening tool to identify potential weight-related health risks.
Formula: BMI = weight (kg) / height (m)²
Limitations
BMI doesn't account for muscle mass, bone density, age, sex, or fat distribution. Athletes may have high BMI due to muscle, not fat.
For a complete health picture, consider tracking additional metrics like body fat percentage, waist circumference, and fitness levels.
