I am Celiac and we have a gluten-free house.
To truly go gluten-free, you need to pay attention to not only foods, but also products like soap, shampoo, lotion, etc, as well as not cooking or prepping food on a contaminated surface.
If you have an Aldi where you are, they have some excellent baking mixes, pasta, and other products. We do a lot of baking from scratch (my 12 year old daughter, especially) and find gf desserts more filling (and more tasty!) because we use almond flour and other flours that are high in protein. We eat meat, eggs, veggies, fruits - whole foods that are filling and gluten-free. For me, the secret is making sure I'm not skimping on the protein, because if I do, I don't feel full. We eat many of the things we ate before going gf - chili, chicken, ribs, pulled pork, all sorts of soups, steak, roasts, stir fry, Indian dishes, Chinese dishes, Mexican dishes ...
My husband makes awesome gluten-free bread in our breadmaker, so bread isn't an issue for us. Also, I found that going without bread for a few months and then trying gf bread makes a LOT of difference. I prefer lettuce wraps to using bread for sandwiches.
One of my favorite go-to's when I'm not feeling full after/in between meals is chia in mango (or other) juice. LOVE it, and it's a complete protein and full of omega-3's!
