It would depend how much of the nutrient is consumed.
Fat
Fats contain 9 calories per gram and is a long lasting energy source.
A pure gram of carbohydrates yields approximately 4 calories of energy, while a gram of protein also provides about 4 calories. In contrast, a gram of fat yields significantly more energy, approximately 9 calories. Alcohol, although not a nutrient, contributes about 7 calories per gram.

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.
Yes, alcohol is considered an energy-yielding nutrient. It provides approximately 7 calories per gram, which is more than carbohydrates and proteins (both at 4 calories per gram) but less than fat (9 calories per gram). However, while alcohol can supply energy, it does not provide essential nutrients and can have detrimental effects on health when consumed in excess.
