I don't feel I have a fad belief. Until about a year ago, I never censored any food. I have always enjoyed a high protein and vegetable diet, but a ton of pasta and pizza too. About a year ago, my wife and I (and by proxy, our kids) cut out gluten, wheat, and sugar. Within a week (closer to three for the wife), we all noticed higher energy levels and just felt better. Our oldest kid had complained of stomach issues for quite some time, up until this change in diet. Interestingly enough, these issues come back when she has bread or pasta (or pizza, as you point out). We all feel worse after eating these foods. We still do it every couple of weeks because, hey, it tastes good. But by avoiding these mostly processed foods, we genuinely feel better. We all still eat burgers; just with no bun. I'd encourage you to try it for two weeks and see if you feel better or not. If not, more ammo for your argument.
