"How many calories your body needs per day?"

Your calorie requirements vary according to height, total body weight, ratio of fat to muscle, age, gender, genes, health and physical exercise. In general, your calorie needs can be reasonably accurately assessed base on two calorie components : Basal Metabolic Rate (BMR) and Physical Exercise.

Your Basal Metabolic Rate is the minimum number of calories needed to power your body while resting. i.e. energy needed by your body to maintain normal functions, like heart beat, respiration and normal body temperature. It accounts for about 60-70% of your calories requirements.
The second major calorie component is physical exercise or activity. The more exercise you take, the more calories you burn.
