cal·o·rie (kl-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

any of several units of heat defined as the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius (1°C) at a specified temperature. The calorie used in chemistry and biochemistry is equal to 4.184 joules. Symbol cal.

In referring to the energy content of foods it is customary to use the 'large calorie', which is equal to 1 kilocalorie (kcal), 1000 cal. Every bodily process—the building up of cells, motion of the muscles, the maintenance of body temperature—requires energy, and the body derives this energy from the food it consumes. Digestive processes reduce food to usable fuel, which the body burns in the complex chemical reactions that sustain life.

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.
