1. A food item contains 40 g of carbohydrates, 35 g of protein, and 24 g of fat. Using standard Atwater factors (carbohydrates = 4 kcal/g, protein = 4 kcal/g, fat = 9 kcal/g), what is the total caloric content of this food item?

Answer: B

Total calories = (carbs x 4) + (protein x 4) + (fat x 9) = (40x4) + (35x4) + (24x9) = 160 + 140 + 216 = 516 kcal.

2. A food item contains 75 g of carbohydrates, 20 g of protein, and 24 g of fat. Using standard Atwater factors (carbohydrates = 4 kcal/g, protein = 4 kcal/g, fat = 9 kcal/g), what is the total caloric content of this food item?

Answer: C

Total calories = (carbs x 4) + (protein x 4) + (fat x 9) = (75x4) + (20x4) + (24x9) = 300 + 80 + 216 = 596 kcal.

3. A food item contains 15 g of carbohydrates, 30 g of protein, and 14 g of fat. Using standard Atwater factors (carbohydrates = 4 kcal/g, protein = 4 kcal/g, fat = 9 kcal/g), what is the total caloric content of this food item?

  1. A316
  2. B296
  3. C306
  4. D286
Show answer

Answer: C

Total calories = (carbs x 4) + (protein x 4) + (fat x 9) = (15x4) + (30x4) + (14x9) = 60 + 120 + 126 = 306 kcal.

4. A food item contains 45 g of carbohydrates, 10 g of protein, and 24 g of fat. Using standard Atwater factors (carbohydrates = 4 kcal/g, protein = 4 kcal/g, fat = 9 kcal/g), what is the total caloric content of this food item?

  1. A396
  2. B456
  3. C436
  4. D441
Show answer

Answer: C

Total calories = (carbs x 4) + (protein x 4) + (fat x 9) = (45x4) + (10x4) + (24x9) = 180 + 40 + 216 = 436 kcal.

5. A food item contains 75 g of carbohydrates, 40 g of protein, and 2 g of fat. Using standard Atwater factors (carbohydrates = 4 kcal/g, protein = 4 kcal/g, fat = 9 kcal/g), what is the total caloric content of this food item?

  1. A498
  2. B488
  3. C478
  4. D468
Show answer

Answer: C

Total calories = (carbs x 4) + (protein x 4) + (fat x 9) = (75x4) + (40x4) + (2x9) = 300 + 160 + 18 = 478 kcal.
