What number of calories are in a gram of carbohydrates?

Each gram of carbohydrates provides 4 calories of energy. This is a fundamental principle in nutrition, as carbohydrates are one of the three macronutrients, alongside proteins and fats. The caloric value of 4 calories per gram is consistent across various types of carbohydrates, whether they come from sources like fruits, vegetables, grains, or sugars. This information is essential for calculating daily caloric intake and understanding how different food choices contribute to overall energy consumption.

In the context of weight management, sports nutrition, and dietary planning, knowing the caloric content of carbohydrates helps individuals make informed decisions about their diets. For instance, someone looking to maintain or lose weight might carefully track their carbohydrate intake in conjunction with their physical activity levels, ensuring they remain within a suitable caloric range for their goals.
