To calculate the percentage of energy from each macronutrient, we first need to know how many kcal each provides per gram: carbohydrates and proteins both provide 4 kcal/g, while fats provide 9 kcal/g. Thus, the energy from carbohydrates is 250g * 4 kcal/g = 1000 kcal, from fat is 66g * 9 kcal/g = 594 kcal, and from protein is 102g * 4 kcal/g = 408 kcal. The percentages are then calculated as follows: carbohydrates = (1000/2000) * 100% = 50%, fat = (594/2000) * 100% = 30%, and protein = (408/2000) * 100% = 20%.
