First of all going gluten free does not mean going carb free, so you can learn how to use other source of carbs, according to your tastes. I use buckwheat, millet and rice, for istance. Be sure to check the list of ingredients of the processed food you buy, there's plenty of hidden gluten. Preparing your owen food as much as possible is also a good option, if it fits you. At the beginning it is hard, but then it becomes easier, I promise.
