Question

Quizplus · Accepted Answer

To calculate the percentage of total kcalories from fat intake, we first need to determine the total kcalories from Jodi's nutritional intake. Since 1 gram of protein and carbohydrates provide 4 kcalories each, Jodi's protein intake accounts for 90 x 4 = 360 kcalories. 
We can determine the remaining kcalories come from fat by subtracting the protein kcalories from the total kcalories: 
2010 - 360 = 1650 kcalories from fat intake. 
Since 1 gram of fat provides 9 kcalories, Jodi's fat intake is 1650/9 = 183 g. 
To determine the percentage of total kcalories from fat intake: 
(183 x 9)/2010 x 100% = 40.6% 
Therefore, the best choice is (C) 40% of total kcalories.
