How many calories are in one gram of carbohydrates?

• A. 2 calories
• B. 4 calories
• C. 7 calories
• D. 9 calories

Answer: (B)

One gram of carbohydrates provides 4 calories of energy. This is a fundamental concept in nutrition, as carbohydrates are one of the three primary macronutrients, alongside proteins and fats. Each macronutrient contributes a specific amount of energy: - Carbohydrates yield 4 calories per gram, - Proteins also yield 4 calories per gram, - Fats provide a higher energy content at 9 calories per gram. Understanding the caloric value of carbohydrates is crucial for professionals in athletic training and nutrition, as it helps in calculating daily caloric requirements and formulating diets tailored to athletes' needs for energy and performance enhancement. Proper knowledge of carbohydrate energy content allows for effective planning of pre-, during, and post-exercise nutrition to optimize athletic performance and recovery.
