How many calories does 1g of ethanol provide?

Ethanol is a type of alcohol that provides a specific amount of energy when consumed. It delivers approximately 7 calories per gram, which distinguishes it from macronutrients such as carbohydrates and proteins, both of which provide 4 calories per gram, and fats, which provide 9 calories per gram. This unique caloric value is important in nutritional contexts, especially when considering dietary sources of energy and the impact of alcohol consumption on overall caloric intake. Understanding this aspect of ethanol can inform decisions regarding dietary patterns and health outcomes, particularly considering that alcohol can contribute significant calories without providing essential nutrients.
