The food quotient (FQ) is calculated from a review of the patient's dietary intake.
Parameters:
(1) number of grams of protein ingested
(2) number of grams of fat ingested
(3) number of grams of carbohydrate ingested
(4) number of grams of alcohol ingested

energy from protein in kcal =
= 4 * (number of grams)
energy from fat in kcal =
= 9 * (number of grams)
energy from carbohydrate in kcal =
= 3.75 * (number of grams)
energy from alcohol in kcal =
= 7 * (number of grams)
total energy =
= SUM(energy from each of the 4 sources)
percent of energy from protein =
= (energy from protein) / (total energy) * 100%
percent of energy from fat =
= (energy from fat) / (total energy)* 100%
percent of energy from carbohydrate =
= (energy from carbohydrate) / (total energy)* 100%
percent of energy from alcohol =
= (energy from alcohol) / (total energy)* 100%
