Calorie Requirement Calculator

An important component of weight maintenance is fully understanding how many calories your body requires everyday to maintain weight. Once you understand this value, you can then take appropriate action to either reduce caloric intake and/or increase caloric expenditure accordingly if your goal is to lose body fat. Basal metabolic rate (BMR) is the amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state (meaning that the digestive system is inactive). The release of energy in this state is sufficient only for the functioning of the vital organs, such as the heart, lungs, brain and the rest of the nervous system, liver, kidneys, sex organs, muscles and skin. BMR decreases with age and with the loss of lean body mass. Increasing your muscle mass will increase your BMR.
