Here's something I tried when I was attempting the vegan raw food diet (and no, I didn't lose any weight or last very long on THAT program!)
You can do this with any whole grain. It would even work with oat groats, which are oats that heven't been cut at all. Just soak them overnight or until they become a chewy consistency. A raw foodist would then eat them just like that! Perhaps with some cinnamon or agave nectar (vegans don't eat honey because it comes from bees).
Here's the caveat, though - calories still count, and it's possible to chow down a massive quantity of soaked whole grains - at least it was for me! Measure out one serving at a time of dry whole grain and then soak.
This would be great for the summertime when it's 90 million degrees outside
and who wants to stand over a hot stove?
