What Is a Calorie?
A calorie is a unit of energy. Your body needs energy to perform every activity including breathing, walking, talking, thinking, and even sleeping. Every food you eat gives your body energy. Some foods provide more calories while some foods provide fewer calories. When you eat more calories than your body needs, your body stores the extra calories as fat. When you eat fewer calories than your body needs, your body starts using stored fat as energy.
This is the basic concept behind weight loss and weight gain. That is why understanding your daily calorie needs is the first step toward building a healthy lifestyle.
