Body Mass Index, or BMI, is a way to estimate body fat based on your height and weight 🏋️. It's a simple calculation that gives you a number to help categorize whether you are underweight, normal weight, overweight, or obese. Think of it as a quick snapshot of your weight status. Unlike more detailed body composition measurements, BMI is easy to calculate and widely used. However, it doesn't account for muscle mass, so it's not perfect for everyone. It's like using a rough map to get an idea of where you are.
