How much more energy does dietary fat provide versus protein or carbs?

Answer

2.25 times the calories.

Dietary fat serves as the most energy-dense macronutrient available to a dog, making it essential for meeting high energy demands. Fat provides substantially more calories per gram compared to either protein or carbohydrates. Quantitatively, fat delivers 2.25 times the caloric content found in an equal measure of protein or carbohydrates. This high energy concentration is vital, but fats also play a crucial secondary role in facilitating the absorption of fat-soluble vitamins, which are necessary for various bodily functions, including immune response and vision.
