Question: 1 / 430

How is the percentage of calories derived from fat calculated?

Grams of fat x 4 kcal/grams / total calories

Grams of fat x 9 kcal/grams / total calories

The percentage of calories derived from fat is calculated by taking the total grams of fat consumed and multiplying it by the caloric value of fat, which is 9 kcal per gram. This value represents the energy produced when fat is metabolized by the body.

After calculating the total calories from fat using this method, you then divide that total by the overall calorie intake to get the percentage of calories that come specifically from fat.

This approach is based on the fact that different macronutrients have distinct caloric values: carbohydrates and protein each provide 4 kcal per gram, while fats provide a higher energy yield of 9 kcal per gram. Understanding this difference is essential for accurately assessing diet compositions and nutritional content.
