Calorie

A unit of energy contained in food and drink. The daily recommended intake of calories for the average woman is 2000 and 2,500 for a man, but this depends on age, size, lifestyle and physical activity. The best way to maintain a healthy weight is to balance the amount of calories you consume with the amount you burn, which often means not eating high calorie foods on a daily basis, such as processed meats, fried foods and desserts.
