aside from the fact that it helps u feel full and saitated (i can do the same thing with will power) why is soluble fiber so important? insoluble helps speed up the passing of food through the digestive system, while soluble does the opposite, and slows down the absorption of nutrients and slows digestion. when i am cutting i want things going in and coming back out as quickly as possible so that i can tap into fat stores for energy as much as possible. Im sure there is a great scientific reason, its just lost on me at the moment, can anyone shed some light on this for me?
