What is the kcal/g value for carbohydrates?

The kcal/g value for carbohydrates is 4.0. This figure is derived from the standard caloric values that are assigned to macronutrients in the context of human nutrition. Carbohydrates provide a significant source of energy for the body, and this value reflects the amount of energy released during the metabolism of carbohydrates.

When carbohydrates are digested and metabolized, they are broken down into glucose, which can then be utilized by the body's cells for energy. In contrast to fats, which have a higher energy content at 9.0 kcal/g, carbohydrates are essential for various metabolic processes but provide lower caloric energy per gram. This lower caloric density is one reason why carbohydrates are often consumed in larger quantities in a balanced diet, particularly from sources such as fruits, vegetables, grains, and legumes.

Understanding these values is important for diet planning, nutritional assessments, and understanding the energy balance within the body. The misinterpretation of carb caloric values can lead to improper dietary choices.
