Calorie consumption refers to the amount or number of calories that an individual consumes through food and beverages over a period of time. Calories are a measure of energy, and the body uses this energy to carry out various functions such as breathing, moving, and maintaining bodily processes. The number of calories required by each person varies depending on factors like age, gender, weight, height, and level of physical activity. Consuming more calories than needed can lead to weight gain, while consuming fewer calories than needed can result in weight loss. Therefore, monitoring and maintaining an appropriate balance of calorie consumption is essential for maintaining a healthy body weight.
