Which nutrients provide 4 kcal per gram?

Explanation:
Energy provided per gram depends on how the nutrient is metabolized for energy. Carbohydrates and protein each yield about 4 kilocalories per gram, while fat provides 9 kcal/g and alcohol about 7 kcal/g. Vitamins don’t supply usable calories. So, carbohydrates and protein are the nutrients that provide 4 kcal per gram.
