The amount of energy provided by FATS is:
9 kcal/g
The correct answer is 9 kcal/g.
Physiological fuel values (Atwater factors): fat 9 kcal/g, carbohydrate 4 kcal/g, protein 4 kcal/g, alcohol 7 kcal/g. Fat yields the most energy because its long hydrocarbon chains are highly reduced and release more energy on oxidation.
4 kcal/g is the value for carbohydrate and protein; 3 and 6 kcal/g do not correspond to any macronutrient.
Short trick: Remember "4-4-9-7": carbohydrate 4, protein 4, fat 9, alcohol 7.
