Verified step by step guidance

1. Understand that in nutrition, the energy provided by macronutrients is measured in kilocalories (kcal), commonly referred to as Calories with a capital C.
2. Recall the standard energy values for macronutrients: carbohydrates provide 4 kcal per gram, proteins provide 4 kcal per gram, and fats provide 9 kcal per gram.
3. Identify that the question asks specifically about carbohydrates, so focus on the energy value associated with carbohydrates.
4. Use the known conversion: 1 gram of carbohydrate = 4 kilocalories (Calories).
5. Conclude that the number of kilocalories provided by 1 gram of carbohydrate is 4 Calories (kcal).
