It can take up to 20 hours of little physical output (e.g., walking) to "burn off" 17,000 kJ (4,000 kcal) [17] more than a body would otherwise consume. For reference, each kilogram of body fat is roughly equivalent to 32,300 kilojoules of food energy (i.e., 3,500 kilocalories per pound or 7,700 kilocalories per kilogram). [18]
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.
According to the FAO, the average minimum daily energy requirement is approximately 8,400 kilojoules (2,000 kcal) per adult and 4,200 kilojoules (1,000 kcal) a child. [3] This data is presented in kilojoules, as most countries today use the SI unit kilojoules as their primary measurement for food energy intake, [ 4 ] with the exception of the ...

The calorie is a unit of energy that originated from the caloric theory of heat. [1] [2] The large calorie, food calorie, dietary calorie, or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius (or one kelvin).
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]
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.
A template (that is US-centric) for recording the nutritional value of foods. SI units must be inserted manually with a {{nbsp}} between the unit and the value. (g = grams, μg = micrograms, IU = international units). Percentage daily value (%DV) are roughly. estimated using US recommendations for adults from the USDA.
