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 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.
Carbohydrates and proteins provide 4 calories per gram, while fats provide 9 calories per gram. Alcohol provides 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) ^^
