Carbohydrates and proteins provide 4 calories per gram, while fats provide 9 calories per gram. Alcohol provides 7 calories per gram.
The amount of energy released when nutrients are burned can vary depending on the type of nutrient. On average, one gram of carbohydrate releases about 4 kilocalories of energy, one gram of protein releases about 4 kilocalories, and one gram of fat releases about 9 kilocalories. This energy is utilized by the body for various functions such as metabolism, physical activity, and maintaining body temperature.
1 gram of fat yields the greatest amount of energy when metabolized, providing 9 calories, compared to 4 calories from 1 gram of carbohydrates or protein.
Fats generally produce the most energy when degraded because they provide more energy per gram compared to carbohydrates and proteins. When fats are broken down through metabolism, they yield more ATP (adenosine triphosphate) which is the energy currency of cells.
One gram of cholesterol contains about 8.8 kilocalories of energy.
Hydrocarbons like gasoline or diesel generally provide the most energy when one gram is burnt, as they have high energy densities. Other fuels like hydrogen gas or methane can also provide a lot of energy per gram when burned.
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.
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.
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.

starch is the nutrient that provides greatest amount of energy. during the process of digestion starch is converted into maltose which is then converted into glucose. breaking down of 1 glucose molecule provides 2780kilo joules of energy.
Fats
Each gram of Carbohydrate contains 4Kcals. Equally, each gram of Protein holds 4Kcal of energy. A gram of fat, however, contains 9Kcal of energy. Each gram of Carbohydrate contains 4Kcals. Equally, each gram of Protein holds 4Kcal of energy. A gram of fat, however, contains 9Kcal of energy.
For each gram of reactant fusion produces more energy than fission.

when they say fat yields this much energy or carbs give that much energy they are talking about calories. and more specifically they are talking about Kilocalories. 1 Kilocalorie is the amount of heat it takes to increase the temperature of 1 kilogram of water 1 degree (i believe fahrenheit) at one atmosphere (basically means sea level ish). heat is the energy. carbohydrates yield 4 calories/gram proteins yield 4 calories/gram fats yield 11 calories/gram alcohol is 9 calories/gram (just threw that one in there) ^^
