How many calories are in one gram of carbohydrate?

One gram of carbohydrate provides 4 calories, which is a fundamental concept in nutrition. Carbohydrates are a primary source of energy for the body, and understanding the calorie content associated with macronutrients is essential for both cooking and dietary planning. This knowledge helps in creating balanced meals and managing energy intake effectively.

Carbohydrates are classified as one of the three main macronutrients, alongside proteins and fats, each contributing a different number of calories per gram. Proteins, like carbohydrates, provide 4 calories per gram, whereas fats supply 9 calories per gram, making the energy from carbohydrates more comparable to that of proteins than fats. Recognizing these differences aids in nutritional calculations and meal preparations, ensuring that chefs and culinary professionals can tailor diets to meet specific energy needs.
