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.

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.
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 most highly concentrated source of energy in the body is Adenosine triphosphate (ATP), which is produced in the mitochondria. ATP is the primary energy currency for cellular processes and is used for muscle contraction, nerve signaling, and biochemical reactions. It provides a quick burst of energy for immediate use by cells.
Carbohydrates provide the most energy in wholemeal bread. When consumed, carbohydrates are broken down into glucose which is the body's main source of energy.
