Dietary fiber is found exclusively in plant foods. It serves as the structural framework in plants and is one of the most abundant compounds in nature. Fiber is the part of the plant that is not broken down in the intestines by human digestive enzymes. Because it is not digested, fiber is not absorbed in the body. (Bacteria in the intestines can ferment soluble fiber, changing it to short-chain fatty acids that are absorbed, but in general, fiber itself is neither digested nor absorbed.)

So, yes fibers are a type of complex carbohydrate, but the bacteria metabolize them into short-chain fatty acids yielding about 1.5-2 kcal/g
