Many calories come from sugar, but that is not necessarily the most concentrated source. Things like proteins and dairy also have a lot of calories.
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 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.
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.
Fats (lipids) offer the most concentrated energy source (i.e the most kilojoules of energy per gram, compared with other nutrients).

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.
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 (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.
