Katch-McArdle formula

The Katch-McArdle formula estimates your daily calorie needs based on your body composition, specifically your lean muscle mass. It starts with your Basal Metabolic Rate (BMR), which is the calories your body burns at rest, calculated using your weight, body fat percentage, and other factors. This formula provides a more personalized estimate because it accounts for how much muscle you have, which burns more calories than fat. It's useful for creating tailored diet and workout plans, especially for those with higher muscle mass or specific fitness goals.
