Carbohydrates contain 4 calories per gram, and 100% of the total weight break down to glucose
Fat contains 9 calories per gram, and only 10% of the total breaks down into glucose.
Protein contains 4 calories per gram, and 58% of protein breaks down into glucose for energy.

b) How many grams of each food group are in this diet?

c) Use the % breakdowns given to calculate the total available grams of glucose from each category.
