UNDERSTANDING CARBOHYDRATES, SUGAR, AND FIBER
Carbohydrates give you energy! All three of the macronutrients —that includes fat and protein—can be used for energy. However, carbohydrates are the body’s go-to energy source. They fuel you throughout daily activities, and during short to moderate lengths of exercise. They are the preferred fuel source for movement, biosynthesis of proteins, brain function, and more. There are about four calories (16.8 joules/gram) per gram of digestible carbohydrates.
