Calorie is the transliteration of French Calorie, which is the unit for calculating calories, and it is divided into big card and small card. 1 calorie is equivalent to the heat used to raise 1 liter of water to 1 degree Celsius at 1 standard atmospheric pressure.

The heat needed by the human body comes from food. When eating, the chemical action of human metabolism breaks down food and converts it into energy. Daily activities, from breathing to running a marathon, are driven by burning calories.

Combustion heat is one of the metabolic processes. If the body needs enough oxygen, water and food, cells will work actively to burn calories at the best speed. Therefore, a healthy diet, good digestion, proper minerals and vitamins and regular exercise are indispensable.

If nutrition is insufficient, the efficiency of metabolism will be reduced, which will slow down the work of cells and greatly reduce the speed of burning calories. "Unused" calories will accumulate to form fat and gain weight.
