Certified Dietary Manager (CDM) Practice Exam

To calculate the percentage of calories that come from fat in this diet, first, we need to know that 1 gram of fat provides 9 calories. So, if the diet provides 36 grams of fat, we can calculate the total calories from fat by multiplying the grams of fat by 9: 36 grams of fat * 9 calories/gram = 324 calories from fat Next, we divide the total calories from fat by the total calories provided by the diet and then multiply by 100 to get the percentage: (324 calories from fat / 1800 total calories) * 100 ≈ 18% Therefore, the correct answer is C: 18% of the total calories come from fat in this diet.
