Fat contains the most kilocalories per gram, providing approximately 9 kilocalories per gram. This makes it the most energy-dense macronutrient compared to carbohydrates and proteins, which both offer about 4 kilocalories per gram. Because of its high energy content, fat plays a crucial role in energy storage in the body.
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.

In food, there are three macronutrients that provide energy. They are fat, carbohydrates, and protein. Fat is the nutrient that provides the greatest amount of energy at nine calories per gram. Protein and carbohydrates provide only four 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.
There are approximately 4 kilocalories (kcal) in a gram of carbohydrates. This value is standard for most carbohydrates, including sugars and starches. However, fiber, a type of carbohydrate, is not fully digested and may provide fewer calories.
The most calorie-dense substance is pure fat, which contains 9 calories per gram.
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.
Carbohydrates and fats are the two most commonly used molecules for energy in the body. Carbs burn at 3.75 kilocalories/gram and fats are roughly twice as energetic
Fat has the most calories per an ounce. There are 9 calories per a gram, so an ounce of fat has 255.06 calories.
Carbohydrate's I think.
