The three main macronutrients\u2014<strong>protein<\/strong>, <strong>fat<\/strong>, and <strong>carbohydrates<\/strong>\u2014each provide energy, but in different amounts per gram:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Protein: <strong>4 kilocalories per gram<\/strong><\/li>\n\n\n\n<li>Carbohydrates: <strong>4 kilocalories per gram<\/strong><\/li>\n\n\n\n<li>Fat: <strong>9 kilocalories per gram<\/strong><\/li>\n<\/ul>\n\n\n\n<p>To find the total calories in a serving, we multiply the grams of each nutrient by its respective caloric value and sum the results. In this case, the food contains 8g of protein (32 kcal), 5g of fat (45 kcal), and 12g of carbohydrates (48 kcal), yielding a total of <strong>125 kcal<\/strong>.<\/p>\n\n\n\n<p>Next, we determine what <strong>percentage of the total calories<\/strong> each nutrient contributes. This is calculated by dividing the calories from each nutrient by the total calories and multiplying by 100. The nutrient with the <strong>highest percentage<\/strong> of total calories is the one that contributes the most energy relative to the others.<\/p>\n\n\n\n<p>From our calculations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Carbohydrates contribute <strong>38.4%<\/strong><\/li>\n\n\n\n<li>Fat contributes <strong>36%<\/strong><\/li>\n\n\n\n<li>Protein contributes <strong>25.6%<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Although fat has the highest energy per gram, in this case, the <strong>greater quantity of carbohydrates<\/strong> in the serving results in carbohydrates contributing the most calories overall. This insight helps consumers make informed dietary choices based on their health goals, such as managing blood sugar, controlling weight, or balancing macronutrients.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Calculate the calories in a serving of food that has 8 grams of protein, 5 grams of fat, and 12 grams of carbohydrate.
