One gram of carbohydrate yields approximately 4 calories. This is a standard measure used in nutrition to estimate the energy provided by carbohydrates when consumed.
Carbohydrates are one of the three macronutrients, along with proteins and fats, that provide energy to the body. When you consume carbohydrates, your body breaks them down into glucose, which is then used as a primary source of energy. The caloric value of carbohydrates is consistent, making it easier to calculate the energy intake from foods rich in carbs.
Understanding the caloric content of carbohydrates can help in managing dietary intake, especially for those who are monitoring their calorie consumption for weight management or other health-related reasons.
