Can I Touch a Calorie?:

Here's another confusing issue. Calories. Some think calories are something you remove or add to the diet. It's as if a calorie is an entity all in and of itself. This is false.
A calorie is a unit of measure. It's used to designate the body's energy requirements. The word calorie relates to the "combustion" or, to produce energy. By definition, a calorie is: The amount of heat required to raise a temperature of 1 gram of water 1 degree Celsius.
