What percentage of daily calories should ideally come from carbohydrates?

The ideal percentage of daily calories that should come from carbohydrates is between 45 to 65 percent. This range is supported by dietary guidelines, including those from the Dietary Guidelines for Americans. Carbohydrates are a primary energy source for the body and play a crucial role in brain function, physical activity, and overall metabolic processes.

A diet that includes 45 to 65 percent of calories from carbohydrates allows for a balanced intake of macronutrients, ensuring that individuals receive enough energy to support their lifestyle and activities. Carbohydrates are also vital for providing fiber, which is important for digestive health, as well as essential vitamins and minerals found in fruits, vegetables, and whole grains.

While lower carbohydrate intake can be suitable for specific dietary plans or health conditions, such as low-carb diets for weight loss or managing blood sugar levels, the general recommendation supports a moderate to high carbohydrate intake for most people to maintain optimal energy levels and health.
