Understanding Body Mass Index (BMI)

Body Mass Index, commonly known as BMI, measures body fat based on height and weight. This helps assess whether a person has a healthy body weight, providing numerical values that align with standardized health categories. BMI is commonly used for population-level health assessment.

Why BMI Matters

BMI matters because it helps identify potential health risks early. It can highlight risks related to obesity or malnutrition, making the process quick and accessible. Early awareness allows for timely lifestyle adjustments. Understanding your body's energy needs is another key piece of the puzzle, which you can explore further with a detailed BMR Calculator.

BMI Categories Explained
