Hey Mr., good to see you again. Here's the solution for question 2(a)(ii): Step 1: Calculate the energy contribution from each nutrient. The total daily energy need is 2500 Kcal. Energy from carbohydrates: 0.60 × 2500 Kcal = 1500 Kcal Energy from fat: 0.30 × 2500 Kcal = 750 Kcal Energy from protein: 0.10 × 2500 Kcal = 250 Kcal Step 2: Calculate the quantity (in grams) of each nutrient. Standard energy values are approximately 4 Kcal/g for carbohydrates, 9 Kcal/g for fat, and 4 Kcal/g for protein. Quantity of carbohydrates: 1500 Kcal4 Kcal/g = 375 g Quantity of fat: 750 Kcal9 Kcal/g ≈ 83.33 g Quantity of protein: 250 Kcal4 Kcal/g = 62.5 g The quantities of each nutrient needed are: Carbohydrates: 375 g Fat: 83.33 g Protein: 62.5 g Send me the next one 📸
