Excess caloric intake, however, is also a factor. Weight is determined by the number of calories consumed and the number used as energy. If more calories are consumed than burned, the result is weight gain. A calorie is an unit of energy-producing potential obtained by food and released upon oxidation by the body, which is the same to the amount of energy necessary to raise the temperature of 1 kilogram of water by 1°C at one atmosphere pressure. Also defined as an unit of measurement for energy. The unit’s name is French and derives from the Latin calor (heat). It is proudly said as Cutting calories needn’t be hard when you have a plan for healthier eating.
Calories are defined in two ways:
- The small calorie or gram calories are the energy required to raise the temperature of 1 gm of water by 1 °C. This is approximately 4.184 J.
- The large calorie or kilogram calorie is the energy needed to increase the temperature of 1 kg of water by 1 °C. This is about 4.184 kJ, and exactly 1000 small calories.
