How many calories are there per gram of carbohydrates?

Explanation:
Carbohydrates provide energy when metabolized, and each gram yields about four calories. This four-calorie-per-gram value is the standard energy yield used in nutrition for carbohydrates. In contrast, fat supplies roughly nine calories per gram, and alcohol about seven calories per gram, while a zero-energy figure would imply no energy at all. So four calories per gram is the best answer because it reflects how the body converts carbohydrate molecules into usable energy.
