The body cannot use water as a source of energy, although it is essential to life. Water contains no calories because the human body cannot metabolize it further to get energy (calories) out of it. This is unlike, say sugar or carbohydrates, that the body digest, metabolizes and gets energy out of. Water is essential for other processes in the body, but it is not converted in any way to make energy.Calorie- The amount of heat energy needed to raise the temperature of one gram of water one degree C.Carbohydrate - An essential nutrient that is the body's main source of energy.

The body primarily metabolizes alcohol for energy, but excessive consumption can lead to nutrient deficiencies and health issues. Therefore, while alcohol contributes calories, it is not a beneficial source of nutrition.
