The primary nutrient that stores energy is fat, which provides a concentrated source of energy for the body. Carbohydrates, particularly in the form of glycogen, also serve as a readily accessible energy source. Additionally, proteins can be used for energy, but their main role is in building and repairing tissues. Overall, fats are the most efficient form of energy storage in the body.
The major nutrient that provides a concentrated source of energy is fat. Fats yield about 9 calories per gram, making them the most energy-dense macronutrient compared to carbohydrates and proteins, which provide about 4 calories per gram each. This high energy content makes fats an essential component of the diet, particularly for long-lasting energy reserves and the absorption of fat-soluble vitamins.
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.

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.
Carbohydrates supply glucose as the main source of energy for the body.
