Fat is the most concentrated form of energy in the body, providing 9 calories per gram compared to 4 calories per gram from carbohydrates and proteins. It is stored in adipose tissue and serves as a high-density source of energy for the body when needed.
Fats (lipids) offer the most concentrated energy source (i.e the most kilojoules of energy per gram, compared with other nutrients).
Energy in all foods comes from calories, which are in starches, fats and proteins. Peanuts contain a high percentage of fat, which is the source of most of their calories, or energy.

The most abundant source of calories in the human body is glycogen, which is stored in the liver and muscles, while the least expensive source of calories is body fat, which is used as a reserve energy source.

Fats (lipids) have the most highly concentrated energy of all organic compounds, providing 9 calories per gram when metabolized. This is more than double the energy content of carbohydrates and proteins, which provide 4 calories per gram when metabolized.
Adenosine triphosphate (ATP) is considered the most concentrated source of stored energy in cells. ATP stores energy in the form of high-energy phosphate bonds that can be readily broken to release energy for cellular processes.
The most highly concentrated source of energy in the human body is stored in the form of triglycerides within adipose tissue (body fat). When broken down, triglycerides release large amounts of energy that can be used by the body for various functions.
