ORIGIN OF CALORIES
Many people try to forget about calories, others are obsessed with counting them, but where did the unit come from and why is food measured in calories?
Originally, a calorie is a measure of the amount of energy required to heat 1 kilogram of water 1 degree Celsius. It was first used in engineering and physics, but eventually found its niche in nutrition, where it is used to measure the amount of energy food contains.
German physician Julius Mayer is credited for beginning a dialogue about food as an energy source. Before Mayer's time, people thought energy was God-given; they made no concrete connections between the food they ate and the energy on which their bodies ran.
A popular early nutrition text published in 1918 by Lulu Hunt Peters outlined 100-calorie portions of many foodstuffs and preached counting calories as a way to regulate weight.
