Question

Fifi is eating 50g per day of a diet that contains 28% protein.

How many kcal per day does this supply her?

Answer 1

Fifi is consuming 56 kilocalories (kcal) per day from the protein in her diet, as she eats 50g of a diet with 28% protein and protein provides 4 kcal/g.

Step-by-step explanation:

The student has asked how many kilocalories (kcal) per day does Fifi get from a diet of 50g with 28% protein. To answer this question, we need to calculate the total kcal provided by the protein. Since protein has an energy content of about 4 kcal/g, we can multiply the amount of protein by this number. First, we calculate how much protein Fifi is ingesting:

50g of diet * 28% protein = 14g of protein.

Next, we convert the protein to kcal:

14g of protein * 4 kcal/g = 56 kcal.

Therefore, Fifi is consuming 56 kcal per day from her diet solely from the protein content.
