My girlfriend is celiac and mildly lactose intolerant and eats pretty much the same as I do. We don't eat to strichly apart from the gluten. I tend to do alot of cooking and buying food. I have converted her to some stranger foods like organ meats and seaweeds.
However I'd never mention "paleo" or similar in real life as I don't like labbels. We just eat healthy home cooked foods. As she has been eating progressivly better over the years she now finds processed gluten-free breads and cakes do not make her feel good. Coconut pancakes are a favorite though :)
