Fat yields the most energy per ounce compared to carbohydrates and proteins. Specifically, fats provide about 9 calories per gram, while carbohydrates and proteins each provide about 4 calories per gram. This higher caloric density makes fats the most energy-rich nutrient, making them an efficient source of fuel for the body.
Fat
The most energy rich nutrient is fat. There are two other nutrients that produce energy for the body and they are protein and carbohydrates.
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.
proteins
Fat has the most calories per an ounce. There are 9 calories per a gram, so an ounce of fat has 255.06 calories.
protein protein

The primary nutrients that yield energy are carbohydrates, proteins, and fats. Carbohydrates provide approximately 4 calories per gram, while proteins also yield about 4 calories per gram. Fats are the most energy-dense, delivering around 9 calories per gram. Alcohol can also provide energy, yielding about 7 calories per gram.
Nutrients that yield greater than 4 kilocalories per gram include fats and alcohol. Fats provide about 9 kilocalories per gram, making them the most energy-dense macronutrient. Alcohol, while not a nutrient, offers around 7 kilocalories per gram. Carbohydrates and proteins, in contrast, yield approximately 4 kilocalories per gram.
It depends on the material. Most metals obey the maximum distortion energy law in which the shear yield is the tensile yield divided by square root of 3, or 0.577 x tensile yield.
Fat. More calories =more heat=more energy.
