How many calories are provided by one gram of carbohydrates?

One gram of carbohydrates provides 4 calories. This is a fundamental aspect of nutrition that highlights the energy contribution of macronutrients. Carbohydrates are one of the primary sources of energy for the body, especially for high-intensity activities and brain function.

The caloric value of carbohydrates is based on their chemical structure and the way our bodies metabolize them. When carbohydrates are consumed, they are broken down into glucose, which is then used for energy. The caloric content of different macronutrients varies: proteins also provide 4 calories per gram, while fats provide 9 calories per gram. Understanding these values is crucial for calculating the energy intake of a diet and for making informed dietary choices, as they play a significant role in overall energy balance and nutrition planning.
