Fibers are carbohydrates that are not decomposed thus lowering the secretion of insulin from pancreas (insulin spike). So the actual spike instead of having high peaks it is moderated now, making:
1) Your cells more sensitive to insulin (avoiding diabetes)
2) Your contains a more rational amount of energy so your body won't to have to store fat.
I don't quite understand how do you define energy since fibers are not technically digested. Well not the insoluble ones. The soluble are digested but, because of their slow digestion they regulate the insulin spike in a positive way: takes longer but spike (imagine this is a graph with peaks) is way lower (a graph with lower insulin peaks is easier for your pancreas to excrete and your body to handle).
Soluble fibers (e.g. oatmeal) helps with cholesterol, which performs a variety of functions in the human body (it's involved in cell wall functions, permeability, bile acids and so on).
> Doesn't fiber require more energy for digestion, which shouldn't be spent while sleeping?
Digestion requires energy and when you sleep there's much energy to be used elsewhere, so actually when you sleep the digestive process is working at full throttle... so I'm not sure what do you mean by shouldn't be spent while sleeping.
When you sleep having an empty stomach is bad, when you sleep having a load of food sitting in your stomach is equally bad, for the sleep quality but your digestion will work better than say if you were awake.
