Our bodies require energy to perform its day to day functions. In the body we call this measure of energy calories. Calories measure the amount of energy a food or beverage has based on the amount of fat, carbohydrates, protein and alcohol it has. Every person needs to consume calories throughout the day to survive and function, however the amount of calories needed varies from person to person depending on height, weight, genetics and level of activity. Some foods do provide us with empty calories, or foods that provide no nutritional value, like sodas and alcohol. It is best to eat these types of foods in moderation to prevent weight gain. In order for someone to gain weight they must be consuming more calories than they are burning off during the day and the opposite for weight loss. If you are interested in finding out your correct calorie intake it is best to seek advice from a medical professional such as a registered dietitian.
