What is the caloric value of carbohydrates per gram?

Carbohydrates provide a caloric value of 4 calories per gram. This value is significant for nutrition and exercise science, as it helps to determine the energy content of foods that contain carbohydrates. Carbohydrates are a primary energy source for the body, especially during high-intensity workouts and activities. Understanding this caloric value is essential for personal trainers and nutritionists when creating dietary plans for clients, as it governs how many calories come from macronutrients in a diet.

The caloric content of carbohydrates is derived from their chemical structure. When consumed, carbohydrates are broken down into glucose, which can be used immediately for energy or stored in muscle and liver tissues as glycogen for later use. This process is crucial for both everyday functioning and athletic performance, making knowledge of caloric values a foundational aspect of sports nutrition.
