““Calories: Calories are a unit invented by modern science to determine how much energy is contained in food. Modern nutritionists recommend that average adults should consume between 2,000 and 2,500 calories per day. It is misleading, however, to assign a general value of energy intake to everyone, as each of us has a different digestion process and different food needs based on our size and body type, and each of us participates in different forms and levels of physical activity.””
