Simple Resting Metabolism Calculator

What is my resting metabolism (or how many calories would I burn each day even if I didn’t move a muscle)?

Your resting metabolism (RMR) (also known as basal metabolism or BRM) is the minimum calories you burn each day for your body to keep everything functioning. The simplest RMR formula, used by this calculator, requires just gender and weight. This formula was developed by Dr. Fred Hatfield of the International Sports Sciences Association and is fairly accurate if your body fat is in the normal range (14-19% for men, 20-25% for women). If your body fat is substantially higher than normal, this formula will overestimate your RMR.
