Percentages are often expressed by utilizing the symbol % or sometimes expressed as a decimal. For example, 35% is equal to the 0.35 expression. When the % symbol is utilized, it is representing a fraction from 100; however, when the decimal version is used, it represents a fraction of

1. It is important to remember that when dealing with percentages, it will always be part of a whole and never bigger than the whole. For example, you can never have a % that is greater than 100. Why is that? If you only had one pie, this pie will represent our 100% or a whole. How could it be possible to eat 110% of that pie, when there is only one whole pie? Now let’s move on to calculating the percent of kcal that comes from each macronutrient. To calculate the percentage of energy derived from each nutrient requires the following equation: kcal from individual macronutrient x 100 = % of energy from that macronutrient Total kcal In order to use that equation, we have to first calculate the kcal from each macronutrient. To determine this, you begin with the number of grams for each macronutrient. For example, if we looked at the nutrition facts panel on a 12 ounce can of regular beer, we would find the following information: (note: while alcohol is not a nutrient, it does provide kcal. This means it must be included in our calculations.) Carbs = 13.28 Lipids = 0.0 g Proteins = 1.28 Alcohol = 12 g With these values, you can then calculate the total kcal value for each as shown below. 13.2 g of Carbs x 4 kcal/8 = 52.8 kcal 0.0 g of Lipids x 9 kcal/g = 0 kcal English (US) А A AaBbcode AaBbcode AaBbCcDc AaBb CcDdEt AaBb Aalbed Heading 1 Heading 2 Title Subot Normal No Spacing 0.0 g of Lipids x 9 kcal/g = 0 kcal 1.2 g of Proteins x 4 kcal/g = 4.8 kcal 12 g of Alcohol x 7 kcal/g = 84 kcal Next, add all kcal values from each macronutrient and alcohol together to determine the total kcal. 52.8 kcal from Carbs + 0 kcal from Lipids + 4.8 kcal from Proteins + 84 kcal from Alcohol = 141.6 Total kcal Now that we know how to convert grams into kcal and calculate total kcal, we can now move on to calculating percent of kcal from macronutrients. Continuing with our beer example from above, we are going to use the following equation: kcal from individual macronutrient X 100 % of energy from that macronutrient Total kcal Let’s begin with carbohydrates. We determined earlier that there are 52.8 kcal from carbohydrates and 141.6 total kcal in that 12 oz. can of beer. Plugging these values into the above equation, we get: 52.8 kcal from carbohydrates x 100 = 37.28 % of kcal came from carbohydrates in that beer 141.6 Total kcal (Note: 52.8 kcal + 141.6 kcal – 0.372881356- you must round to the nearest 10,000″ to get 0.3728.

Now we need to repeat the same process for lipids, proteins and alcohol. See below. 0 kcal from lipids x 100 = 0 % of kcal came from lipids 141.6 Total kcal 4.8 kcal from proteins_ x 100 = 3.38 % of kcal came from proteins 141.6 Total kcal 84 kcal from alcohol x 100 = 59.32 % of kcal came from alcohol 141.6 Total kcal Once you have calculated your percent kcal from your macronutrients (including alcohol if present), you always want to double check your math to see if your calculations are correct. Remember that percentages are part of a whole. If you add up all of your percentages, it should equal 100%. Continuing with our beer example: 37.28 % of kcal from carbohydrates 0% of kcal from lipids 3.38 % of kcal from proteins 59.32 % of kcal from alcohol 99.98 % As you can see this does not add up to be exactly 100 %. This is because we rounded to the nearest 10,000th of a decimal for the carbohydrate, lipid and alcohol calculations. As long as you are within 0.1 %, then your math checks out.
