Understand How Your Caloric Intake Affects Your Metabolism
Calories provide energy for your body, but your metabolism decides how it’s going to use the calories you eat. If you take in more calories than your body require, your body will generally store the extra calories as fat. Therefore, when you consume more calories than you need over a period of time, you gain weight. If you take in fewer calories than your body requires, or burn calories via exercise, your body will call upon the stores of fat to meet its energy requirements. If you do this over a period of time, you will lose weight.
