This has implications for weight loss strategies. This means that the more weight you lose, the less energy (calories) your body needs to maintain homeostasis. This is why the Katch-McArdle Formula includes body fat percentage but does away with gender (since the body fat percentage variable is a more accurate indicator of muscle mass than gender).įrom the BMR calculator, you can see that losing weight also decreases your BMR. However, we know that the person with more muscle mass will need to consume more calories to maintain homeostasis since more muscle requires more energy. The two people will have the same BMR calculation. Muscle mass influences BMR, although it is not necessarily captured in the equations.įor example, comparing two people who have the same height, age, weight, and gender but one person who has more muscle mass.

The only variables in the equations that one can change are body weight and body fat percentage.


The following equations are all validated ways of calculating BMR.
