I would imagine protein.
Carbohydrates supply glucose as the main source of energy for the body.
Water does not supply calories to the/our body.............
The Nutrient That Doesn't supply calories to the human body is the water.......
Carbohydrates are the primary nutrient that supplies the main energy source for the body in the form of sugars. They are broken down into glucose, which is utilized by the body's cells for energy. Carbohydrates can be found in foods such as fruits, vegetables, grains, and legumes, playing a crucial role in fueling various bodily functions and activities.
the metabolism extracts energy from food
The three nutrients that provide energy are carbohydrates, proteins, and fats. Carbohydrates are the body's primary energy source, while fats provide a concentrated energy reserve. Proteins can also supply energy but are primarily used for growth, repair, and maintenance of tissues. Each nutrient plays a distinct role in metabolism and overall health.
Carbohydrates do not function as a builder of body tissue. While they are a source of energy for the body, carbohydrates are primarily used for fuel rather than for building and repairing tissues. Proteins are the main nutrient class responsible for building body tissues.
Alcohol does not provide essential minerals or protein, and while it does supply calories, these are often referred to as "empty calories" because they lack nutritional value. 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.
carbohydrates
Protien
Carbohydrates are the nutrient that is the easiest to be broken down and absorbed for energy use in the body. Carbohydrates are quickly converted into glucose, which is then used by the body for energy.
sugar that is available in your blood stream gets used up first, then glycogen thru glycolysis breaks down, to supply the energy. After all sugar has been used, fat will be the next to be burnt by your body
