What is the caloric (kcal) yield of nutritional fat?

4 kcal
7 kcal
9 kcal
12 kcal

The correct answer is: 9 kcal

The caloric yield of nutritional fat is 9 kcal per gram. This value is significant because it reflects the energy density of fat compared to other macronutrients. Fats are the most energy-dense macronutrient, providing more than double the calories per gram than carbohydrates and proteins, which each provide approximately 4 kcal per gram. This higher caloric yield contributes to the role of fats in energy storage and metabolism in the body. Understanding this difference in caloric yield is essential for dietary planning and for making informed decisions about macronutrient ratios in nutrition.
