So… Really… What are Calories
Scientific Definition
Calorie - the quantity of heat needed to raise the temperature of 1kg (kilogram) of water from 0 to 1⁰C.
Are You Confused?
So was I after reading the scientific definition of the calorie…
How does that definition relate to my body when I eat food?
History of Calorie
Well… It all began with Wilbur Olin Atwater. He made ground breaking research in human nutrition.
So what does Olin have to do with the Calorie?
The United States began using the Calorie only after Atwater’s use of it in his work in 1887. The most interesting part is that the only reason Atwater adopted the term “Calorie” is because it was the ONLY energy unit in the English dictionary.
Current Units of Energy
Joule
calorie (the “c” is lower case and is used pertaining to chemistry and physics)
kilocalorie
What is even more interesting is that the Calorie seen on the American nutrition facts label is actually measured in kilocalories even though the label plainly states Calorie (1 kilocalorie = 1,000 Calories).
Nutritional Definition of the Calorie
The chemical energy stored in foods. Basically the Calorie represents the energy used by the cells of your body to allow it to function. When this energy is used heat is released thus the connection to our initial definition of the Calorie.
3 sources of Calories

Empty Calories are calories but this type of calorie has no nutritional value.
