The one fault oatmeal has is that it's usually not very high in protein. For those of you that think oatmeal isn’t very filling or you’re hungry 1 hour after eating it, all you need to do is add some protein and healthy fat. That's why I'm a huge supporter of making protein oatmeal. Adding protein powder to my oatmeal ensures that breakfast will keep me full for hours and the vanilla protein powder I use adds extra flavor (and sweetness) as well.
