Fats (lipids) offer the most concentrated energy source (i.e the most kilojoules of energy per gram, compared with other nutrients).
Nuts store energy in the form of fats, proteins, and carbohydrates. The fats in nuts are a concentrated source of energy, providing a high amount of calories per gram. This energy is released when the nutrients in the nuts are metabolized by the body.

Nutrients and energy.
Fats are the most concentrated source of energy for the body, providing about 9 calories per gram, compared to carbohydrates and proteins, which offer approximately 4 calories per gram. This high energy density makes fats an essential nutrient for long-term energy storage and metabolism. Additionally, fats play crucial roles in hormone production, nutrient absorption, and cell structure.
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.
Nutrients are used by the body's cells as a source of energy
Its energy is derived from the nutrients in the food it consumes.
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.
