In a protein supplement that contains 154 total kcalories, 11 grams of protein, and 17 grams of carbohydrate, how many kcalories come from protein and what percentage of this product's total kcalories are from the protein? remember to explain why this is important information.

As the calorific value of protein is about 4 kcal per gram. So, if any food supplement has 11 grams of protein, it signifies that it comprises 44 kcal of calorific value, that is, 11*4 kcal. In the given case, food supplement has 154 kcal as the total nutrition value, then the percentage of calorific value of protein from the total calorific value is:  

44 * 100 / 154 = 28.57 %.  

And this is as important information as protein is an essential constituent of the diet and the body requires an adequate amount of protein for the formation of muscles and other essential activities.
