What is BMR?
Your Basal Metabolic Rate (BMR) is the amount of energy your body expends while at rest in a neutrally temperate environment. In this state, your energy will be used only to maintain your vital organs, which include the heart, lungs, kidneys, the nervous system, intestines, liver, lungs, sex organs, muscles and skin.
