Unless you're talking about that sugary instant oatmeal that comes in packets, what you're saying is simply untrue. Oatmeal is very nutritious and it is not a high glycemic index food.
Back when I used to eat unhealthy I'd start my day off with a cup of coffee w/sugar and maybe something sweet then I'd head out the door and I'd always crash a couple hours later and have no energy. But now I often start my day with oatmeal and I always have a very stable amount of energy throughout the day.... and I don't even feel hungry again until like 2 o'clock.
Oatmeal is fantastic, unless you're you're talking about that instant kind I mentioned before.
Even your paleo people list it at 55... which is considered low.
