large calorie the calorie now used only in metabolic studies; also used to express the fuel or energy value of food. It is equivalent to the kilocalorie. Symbol C.
small calorie calorie, when the term large calorie had broader meaning.
cal·o·rie (k l  -r )n. 1. A unit of energy-producing potential supplied by food and released upon oxidation by the body, equal to the amount of energy required to raise the temperature of 1 kilogram of water by 1°C at one atmosphere pressure. Also called nutritionist's calorie. 2. The unit of heat equal to the amount of heat required to raise the temperature of 1 kilogram of water by 1°C at 1 atmosphere pressure. Also called kilocalorie, kilogram calorie, large calorie. 3. Any of several approximately equal units of heat, each measured as the quantity of heat required to raise the temperature of 1 gram of water by 1°C from a standard initial temperature at 1 atmosphere pressure. Also called gram calorie, small calorie. 4. The unit of heat equal to 1/100 the quantity of heat required to raise the temperature of 1 gram of water from 0 to 100°C at 1 atmosphere pressure. Also called mean calorie. |
Calorie
A unit of heat measurement used in nutrition to measure the energy value of foods. A calorie is the amount of heat energy needed to raise the temperature of 1 kilogram of water 1°C.

In referring to the energy content of foods it is customary to use the “large calorie,” which is equal to 1 kilocalorie (kcal). Every bodily process, including the building up of cells, motion of the muscles, and the maintenance of body temperature, requires energy, which the body derives from the food it consumes. Digestive processes reduce food to usable “fuel,” which the body “burns” in the complex chemical reactions that sustain life. The amount of energy required for these chemical processes varies. Factors such as weight, age, activity, and metabolic rate determine a person's daily calorie requirement. Nutrition experts have computed daily calorie requirements in terms of age and other factors. These tabulations serve only as guides; they cannot, of course, embrace all individual variations.
From its daily intake of energy foods, the body uses only the amount it needs for energy purposes. The remainder is stored as fat. If the average adult consumes more calories than the daily requirement, he or she will gain weight. However, if consumption is less than recommended daily requirements, the body will supplement its energy sources by drawing upon stores of fat and the person will lose weight.

calorie,
n the amount of heat required to raise 1 g of water 1° C at atmospheric pressure, also called gram calorie or small calorie. A great calorie, or kilocalorie, consists of 1000 small calories. The kilocalorie is the unit used to denote the heat expenditure of an organism and the fuel or energy value of food.

Q. Is it true that when you eat celery you burn more calories than you consume?
A. There is a common belief that celery is so difficult for humans to digest, that it has negative calories because human digestion burns more calories than can be extracted. In an episode of Food Detectives they proved that celery does not have "negative calories", but states that the amount of calories burned digesting it burns the calories taken in, and one would lose weight if one only consumed celery.
