Milk contains calories which give you energy. Water doesn't contain calories.
Protein, fat, and carbohydrates provide energy for the body. Carbohydrates provide bodily energy the quickest. Fats/Lipids are stored as body fat for later/emergency usage. Proteins usually are used to create bones, tissue, and muscle - they don't really provide energy.
Water does not supply calories to the/our body.............
Water, vitamins, and minerals do not supply any kilocalories of energy to the body. However, they are vital in the processes that release energy from carbohydrates, proteins, and fats.
Calories, on a molecular level, are broken up into only a few main groups (carbohydrates / sugars, proteins, and lipids / fats). When these molecules are broken down in your body, your liver converts them into a form where they can be used for energy for your body.
There are four basic food categories that give the body calories (energy); fat, carbohydrate, protein, and alcohol. Fat gives 9 calories per gram. Carbohydrates and proteins give 4 calories per gram. Alcohol gives 7 calories per gram.
The Nutrient That Doesn't supply calories to the human body is the water.......
Foods high in fat have the most energy per gram (i.e. 9 calories/gram vs. 4 calories/gram for carbohydrates or proteins). This is why it is easy to get fat if you eat fatty food and are not performing work involving lots of physical labor to burn those calories.
Carbohydrates, fats and proteins yield the energy the body needs to fuel its various activities. Vitamins, minerals and water do NOT yield energy, but perform other tasks such as maintenance and repair.
