So on the back of the drag curve the lower the speed the more drag and therefore more thrust required to maintain it. How the engine is controlled is irrelevant. It's thrust v drag. The flight path remains constant on an ILS. So thrust controls rate of descent. at a lower speed you need a lower rate of descent. This required more thrust.
