Common Mistakes
Be honest with yourself. If you exaggerate your activity level or body fat you’re going to end up with a calorie level that’s not very accurate. So why cheat yourself.
The Formula
This calorie calculator uses the Katch-McArdle Formula. We feel this is the most accurate formula to use when calculating ones energy needs because it takes into account a persons body composition when calculating calorie needs. Because muscle burns more calories at rest than fat, a person with a higher % of muscle mass will typically need more calories than someone who weighs the same but has more fat mass.
