Carbohydrates often get unfairly criticized in popular diet culture, but they’re actually essential for multiple crucial body functions. Far from being just empty calories, carbs serve as your body’s preferred energy source, powering everything from daily activities to intense workouts. Your brain particularly depends on carbohydrates, using roughly half of all the sugar-derived energy in your entire body to fuel cognitive functions.
Beyond immediate energy needs, carbs get stored as glycogen in your muscles and liver, creating an energy reserve your body can tap into between meals or during physical activity. They also play an important role in preserving protein for its primary jobs like building and repairing tissues, rather than burning it for fuel.
The fiber found in complex carbohydrates supports digestive health and nurtures the beneficial bacteria in your gut microbiome. While the recommended intake varies by individual, most people should aim for 45-65% of their daily calories from carbohydrates, with emphasis on complex sources like whole grains, vegetables, and legumes rather than refined sugars and processed foods.
