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.
Carbohydrates, proteins, and fats are the three primary categories into which food molecules fall. Carbohydrates provide energy, proteins are needed for growth and repair, and fats are important for energy storage and hormone production.
Carbohydrates
vitamins
There are three main nutrients that provide energy which are carbohydrates, proteins and fats. They are also called macronutrients and are needed for metabolism, growth and other body functions.
We get most of our food energy from carbohydrates. Carbohydrates are the body's preferred source of energy and are broken down into glucose to fuel our cells. Proteins are essential for growth and repair of tissues, but they are not as efficient as carbohydrates in providing energy for the body.
The body first uses carbohydrates for energy, then it uses fats, and finally it uses proteins as a source of energy. Proteins are typically used as an energy source only when carbohydrates and fats are unavailable.
proteins, fats, carbohydrates, and water
The collective name for fats, proteins, and carbohydrates is obesity.
The three sources are carbohydrates, proteins and lipids. There are more like vitamins, minerals, and water.
The three main types of molecules in food that provide us with energy are carbohydrates, proteins, and fats. Carbohydrates are the body's preferred source of energy, while proteins and fats play important roles in energy production and storage.
The primary function of carbohydrates is providing energy for the body. Fats and proteins also provide energy, but carbohydrates are the main source.
