Fat provides the highest caloric value per gram, making it a crucial nutrient for energy supply in the diet. It contains approximately 9 calories per gram, while carbohydrates and proteins each provide about 4 calories per gram. Fiber, though it is important for digestive health, does not provide significant calories, as it is not fully digestible by the human body.

The high caloric density of fats means they are effective for energy storage, allowing the body to store a larger amount of energy in a smaller volume of food. This is particularly beneficial in scenarios where space or availability of food is limited. Understanding the caloric contribution of different macronutrients is essential for making informed dietary choices and managing energy balance.
