What does daily calorie consumption mean?

Daily calorie consumption generally refers to how many calories in one day your body needs to carry out normal bodily functions. Your body uses calories whether you are active or not. Depending on your height and weight determines how many calories your body needs each day. People who are overweight need more calories to maintain their lives than people who are not overweight. Same holds true for people who are very active physically (needing more calories to burn), than those who are sedentary (not needing as many calories). If you are looking at this from a losing weight standpoint, daily calorie consumption can also mean how many calories are needed to sustain life and at the same time allow someone to lose weight safely. You can find out how much you need each day calorie wise through having a Basic Metabolic Rate (BMR) test done. From there, you can determine how many calories can be reduced safely to lose weight, usually 1-2 lbs. per week.
