A calorie is a unit of measure used to quantify the amount of energy a food or beverage contains. Your body uses these calories, or energy, to perform daily activities and even for sleeping. However, many individuals eat too many calories, especially empty calories, which leads to weight gain. Empty calories are from added sugars and solid fats. These items add extra calories but few nutrients. Therefore, empty calories need to be limited! Common foods that contain high levels of empty calories include cakes, pastries, soda, pizza, cheese, and ice cream.
