Based on the work of Atwater, it became common practice to calculate energy content of foods using 4 kcal/g for carbohydrates and proteins and 9 kcal/g for lipids. [2] The system was later improved by Annabel Merrill and Bernice Watt of the USDA, who derived a system whereby specific calorie conversion factors for different foods were proposed. [3]
The distribution of macros will vary based on your personal goals and macro ratio — a bodybuilder or weightlifter might want to increase the amount of protein on their plate.
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.

The Holliday-Segar formula is a formula to help approximate water and caloric loss (and therefore the water requirements) using a patient's body weight. [1] Primarily aimed at pediatric patients, the Holliday-Segar formula is the most commonly used estimate of daily caloric requirements. [ 2 ]
Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g).
Carbohydrates and proteins provide 17 kJ approximately (4 kcal) of energy per gram, while fats provide 37 kJ (9 kcal) per gram. [8] However, the net energy derived from the macronutrients depends on such factors as absorption and digestive effort, which vary substantially from instance to instance.
Acceptable Macronutrient Distribution Ranges (AMDR), are a range of intake specified as a percentage of total energy intake. Used for sources of energy, such as fats ...
