I have, though I haven't tried to adhere to it. It is one of the reasons, however, that I don't panic about breakfast. If breakfast is later, that's fine. When I used to do morning Zumba, I found it worked best for me if I didn't eat beforehand. I had my morning tea, but that was pretty much it. When I got home, I would make myself a cooked breakfast.

Now, I am usually up several hours before my kids and husband are awake (ME time!) I usually only start cooking after they are up. If I'm not up to cooking, then my breakfast can be much later. Right now, I think that fixing what I eat is probably more important than when I eat it. :-) (#1 thing there is to fix snacks... so, back to nuts, jerky and pork rinds - I often make the pork rinds into nachos.)
