The calories consumed from foods and beverages must be balanced with the calories used in normal body functions and physical activity. An imbalance can lead to weight gain or weight loss.
Calculating Caloric Intake
The caloric intake can be calculated by adding up the calories in all the foods and drinks that a person consumes in a day. This can be done using food labels, food composition tables, or online calorie counters.
Factors Affecting Caloric Intake
Several factors can affect a person's caloric intake, including age, sex, weight, height, metabolic rate, and level of physical activity.
