Seriously...
This falls into the realm of get over it.
The polls choices are all obnoxious, IMO. You don't have to explain, lie, or shame yourself to stick with your lifestyle. Just quietly eat what you like and when the inevitable "are you doing Atkin's blahblahblah" comes up, just say you only eat clean, whole foods. It's the complete truth. Also, telling people you're gluten intolerant just means they're going to be thoughtful enough to bring GF baked goods for dessert next time.
Eat the sauce. Grill a steak or five. Make a nice salad, and serve fresh berries with coconut cream for dessert. And don't raise a big stink about to DH or your guests. Adults don't have to eat things they don't want. And everyone doesn't have to cater to your preferences.
