one thing that you have to remember while on a low carb, low GI diet. Is the Glycemic Response (GR) of carbs. While everyone here should know that high GI carbs can spike insulin which can promote excess fat storage among othere thins. But on the other hand, to big of a serving of low GI carbs can cause a insulin resonse (that is the GR) as well which may not cause insulin levels to spike, but they can rise enough to promote fat storage as well.
