The name calorie is used for two units of energy. The small calorie or gram calorie (symbol: cal) is the approximate amount of energy needed to raise the temperature of one gram of water by one degree Celsius. The large calorie, kilogram calorie, dietary calorie, nutritionist's calorie or food calorie (symbol: Cal, equiv: kcal) is the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius. The large calorie is thus equal to 1000 small calories or one kilocalorie (symbol: kcal). In the International System of Units, the joule. One small calorie is around 4.2 joules (one large calorie or kilocalorie is therefore approx. 4.2 kilojoules). Factors used to convert calories to joules are numerically equivalent to expressions of specific heat capacity of water in joules per gram or per kilogram. The conversion factor depends on the definition adopted.
Quote: "For a more balanced approach to a 1 pound per week weight loss, increase your activity. Decrease calorie intake by 250 calories per day and exercising to expend (use up) the other 250 calories. This approach prevents a decrease in your metabolic rate and promotes increased lean muscle mass."
