Answer j:
Explanation / Answer
a.) 1 gm Fat contains 9 Calories.
So total intake of calories from fat is = 83 x 9
= 747 Calories or 0.747 KCal
b.) 1 gm Protein contains 4 Calories.
So total intake of calories from Protein is = 32 x 4
= 128 Calories or 0.128 KCal
c.) 1 gm Carbohydrate contains 4 Calories.
So total intake of calories from Carbohydrate is = 200 x 4
= 800 Calories or 0.8 KCal
d.) Total KCal intake of Jerold's from meal is = 747 + 128 + 800
= 1675 Calories or 1.675 KCal
e.) Total kcal that came from fat = (0.747/1.675) x 100
= 44.5 %
f.) Total kcal that came from Protein = (0.128/1.675) x 100
= 7.6 %
g.) Total kcal that came from carbohydrate = (0.8/1.675) x 100
= 47.76 %
