No, it measures the ammount of heat output that would heat a millilitre of water 1 degree Celsius. So if you were to burn 1000 calories of energy, it would heat one millilitre 1000 degrees Celsius or it would heat 1 litre 1 degree Celsius.
The calorie is used for heat, 1 calorie heats 1 gram of water by 1 degC. The Joule is used for mechanical energy, but there is a fixed relation, 1 calorie = 4.2 Joules

A calorie
Calorie: a unit of heat energy commonly used in nutrition to measure the energy content in food. BTU (British Thermal Unit): a unit of heat energy often used in the United States to measure energy required for heating and cooling. Joule: a unit of heat energy in the International System of Units, used to measure heat and mechanical work.
A calorie is a measure of energy. It doesn't make sense to ask how much energy you need to lose energy.
A calorie, by definition, is the amount of energy it takes to raise 1 gram of water 1 degree celsius. It is a measure of heat energy. To people, calories are found in foods and drinks, which give us energy. Each calorie is like a measure of potential energy we can then use. Living and exercising thus "burns" calories as we use up the energy we have consumed.
The large calorie, kilogram calorie, dietary calorie or food calorie approximates the energy needed to increase the temperature of 1 kilogram of water by 1 °C.
A calorie is a unit of measure for the potenetial energy stored inside of a molecule, or a measure of the amount of energy it takes to raise one gram of water 1 degree celsius.
The calorie (usually expressed in kilocalories)
the measure of energy the body is able to produce from food
