Question

Key: Carbohydrates contain 4 kcalories per gram, protein contains 4 kcalories per gram, and fat contains 9 kcalories per gram. To calculate the percent of kcalories from protein, carbohydrate or fat, (1) determine the total kcalories in the food (calculate the kcals of protein, carbohydrate and fat and add them together) and (2) divide the kcalories in the individual component (protein, carbohydrate or fat) by the total kcalories in the food.

Calculate the grams of protein, carbohydrate and fat in a meal that is 600 calories and is 15% protein, 60% carbohydrate and 25% fat. Show your work.

Thank you for the help, I will rate.

Explanation / Answer

0.15 * 4 + 0.60 * 4 + 9 * 0.25 = 5.25 kcal

5.25 kcal *x = 600 cal

x = 114.285714286/1000

hence

carbohydrate = 114.285714286/1000* 0.6 = 68.57142/1000

protein = 114.285714286/1000* 0.15 = 17.142857/1000

fat = 114.285714286/1000 * 0.25 = 28.5714285/1000
