At the time I read Wheat Belly, I had already been wheat and gluten free for almost a year. I didn't experience any of the changes the author claimed would happen after giving up wheat. I gave up gluten because of a digestive problem, but the author blamed wheat on a lot of other problems as well. It just wasn't so in my case. It also never had an impact on my weight in either direction.
I personally don't eat gluten free wheat substitutes. I don't eat any type of bread or baked products. I missed it at first, but it didnt' take long for me to get used to it. I used to eat gluten free pasta, such as quinoa pasta (really good), but even gave that up. I eat oats for breakfast sometimes, but I don't eat grains other than that.
Going completely gluten free is hard, especially if you feed a family that doesn't plan to avoid it. Gluten is hidden in so many products where wheat isn't a listed ingredient. Avoiding it when possible may be the best option.
Good luck
