A diet provides 2,000 kcal of which 20% of the energy is from fats and 15% from protein. How many grams of carbohydrates are contained in the diet?

To determine the amount of carbohydrates in the diet, we first need to calculate the contributions of fats and protein to the total caloric intake, and then use that information to find out how many calories are from carbohydrates.

1. Calculate calories from fats: Since 20% of the energy is from fats, we take 20% of 2,000 kcal.

• Calories from fats = 0.20 × 2,000 = 400 kcal.

2. Calculate calories from protein: With 15% of energy coming from protein, we calculate that as well.

• Calories from protein = 0.15 × 2,000 = 300 kcal.

3. Calculate total calories from fats and protein:

• Total calories from fats and protein = 400 kcal + 300 kcal = 700 kcal.

4. Calculate calories remaining for carbohydrates: To find the calories that come from carbohydrates, we subtract the total calories from fats and protein from the total caloric intake.

• Calories from carbohydrates = Total calories - Total calories from fats and protein = 2,000 kcal - 700 kcal = 1,300 kcal.

5. Convert calories from carbohydrates to grams
