    en.wikipedia.org/wiki/Calorie

    In other scientific contexts, the term "calorie" and the symbol "cal" almost always refers to the small unit; the "large" unit being generally called "kilocalorie" with symbol "kcal". It is mostly used to express the amount of energy released in a chemical reaction or phase change, typically per mole of substance, as in kilocalories per mole. [32]

  3. KCAL - Wikipedia

    en.wikipedia.org/wiki/KCAL

    kcal, kilocalorie (1,000 calories), a unit of energy (sometimes referred to as 1 Calorie, with a capital C, as opposed to a small c). Topics referred to by the same term This disambiguation page lists articles associated with the title KCAL .

  4. Empty calories - Wikipedia

    en.wikipedia.org/wiki/Empty_calories

    Granulated sugar provides energy in the form of calories, but has no other nutritional value. In human nutrition, empty calories are those calories found in foods and beverages (including alcohol) [1] composed primarily or solely of calorie-rich macronutrients such as sugars and fats, but little or no micronutrients, fibre, or protein.

  5. Nutrition - Wikipedia

    en.wikipedia.org/wiki/Nutrition

    All macronutrients except water are required by the body for energy, however, this is not their sole physiological function. The energy provided by macronutrients in food is measured in kilocalories, usually called Calories, where 1 Calorie is the amount of energy required to raise 1 kilogram of water by 1 degree Celsius. [27]

  6. List of macronutrients - Wikipedia

    en.wikipedia.org/wiki/List_of_macronutrients

    Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [2] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.

  7. Dietary energy supply - Wikipedia

    en.wikipedia.org/wiki/Dietary_energy_supply

    The dietary energy supply is the food available for human consumption, usually expressed in kilocalories or kilojoules per person per day. It gives an overestimate of the total amount of food consumed as it reflects both food consumed and food wasted. [1]

  8. Very-low-calorie diet - Wikipedia

    en.wikipedia.org/wiki/Very-low-calorie_diet

    VLCDs are defined as a diet of 800 kilocalories (3,300 kJ) per day or less. [8] [9] Modern medically supervised VLCDs use total meal replacements, with regulated formulations in Europe and Canada which contain the recommended daily requirements for vitamins, minerals, trace elements, fatty acids, protein and electrolyte balance.

  9. Specific heat capacity - Wikipedia

    en.wikipedia.org/wiki/Specific_heat_capacity

    The grand calorie (kilocalorie, kilogram-calorie, food calorie, kcal, Cal) is 1000 small calories, 4184 J exactly. It was defined so that the specific heat capacity of water would be 1 Cal/(°C⋅kg).
