Katch-McArdle Equation
The Katch-McArdle Equation is a formula used to estimate how many calories your body needs daily to maintain your current weight. It considers your lean body mass—the weight of your muscles, bones, and organs excluding fat—making it more precise for individuals with different body compositions. By calculating your lean mass and multiplying it by specific activity factors, the equation helps determine your Basal Metabolic Rate (BMR), which is the calories burned at rest, plus additional calories based on your activity level. This insight aids in planning nutrition and fitness strategies effectively.
