Q. If a meal contains 50 grams of carbohydrates, 20 grams of protein, and 10 grams of fat, what is the total caloric value of the meal? (Carbohydrates = 4 cal/g, Protein = 4 cal/g, Fat = 9 cal/g) (2023)
Q. If a person consumes 300 grams of carbohydrates in a day, what percentage of their total caloric intake (assuming 1 gram of carbohydrate = 4 calories) does this represent if their total intake is 2400 calories? (2020)
Q. If a person consumes 3000 calories a day and wants to ensure that 25% of their intake is from proteins, how many grams of protein should they consume (1 gram of protein = 4 calories)?
A.
150 grams
B.
200 grams
C.
250 grams
D.
300 grams
