Calorie Calculation Exercises
1. A serving of two cookies has 150 kcal and 12 grams of fat. What percentage of total calories is fat? 1) Divide fat calories by the total kilocalories 2) Fat = 9kcal/g 3) 12g x 9kcal/g = 108kcal/g 4) 108kcal / 150kcal = .72 5) .72 x 100 = 72% total calories from fat
2. How many grams of protein are in a 2400kcal diet with 15% of total kcal from protein? 1) Grams / total kcal = total percentage of kcal from protein 2) Protein = 4kcal/g 3) x / 2400kcal = .15(15% of total kcal from protein decimal format) 4) 2400kcal x .15 = 360 5) 360 / 4kcal/g = 90gm of protein
3. A 1500 kcal diet is 65% carbohydrate. How many kcal come from CHO? How many grams of CHO? …show more content…
1) 1500kcal = 65% carbohydrate 2) Carbohydrate = 4kcal/g 3) Formula for kcal 4) Kcal / 1500kcal = 65% of carbohydrates 5) x / 1500kcal = .65(65% of carbohydrates in decimal format) 6) .65 x 1500kcal = 975kcal come from CHO 7) Formula for grams 8) Grams of carbohydrates x 4kcal/g = 975kcal from CHO 9) 975kcal / 4kcal/g = 243.75gm of …show more content…
1485kcal for carbohydrates A 2700 kcal diet contains 55% carbohydrate, 20% protein, and 25% fat. How many kcal and grams are provided for each nutrient? 1) 2700kcal = 55% carbohydrate, 20% protein, 25% fat 2) Carb = 4kcal, Protein = 4kcal, Fat = 9kcal 3) Kcal formula for carbohydrate 4) x = kcal x / 2700kcal = .55(55% carbohydrate into decimal format) 5) x = .55 x 2700kcal = 1485kcal of carbohydrate 6) Grams formula for carbohydrate 7) x = grams x multiplied by 4kcal = 1485kcal 8) x = 1485kcal / 4kcal = 371.25grams of carbohydrates 9) Kcal formula for protein 10) x = kcal x / 2700kcal = .20(20% protein into decimal format) 11) x = .20 x 2700kcal = 540kcal of protein 12) Grams formula for protein 13) x = grams x multiplied by 4kcal = 540kcal 14) x = 540kcal / 4kcal = 135grams of protein 15) Kcal formula for fat 16) x = kcal x / 2700kcal = .25(25% fat into decimal format) 17) x = .25 x 2700kcal = 675kcal of fat 18) Grams formula for fat 19) x = grams x multiplied by 9kcal = 675kcal 20) x = 675kcal / 9kcal = 75grams of
