I've been eating raw for almost two years but I don't call myself a raw foodist because I don't believe it as a lifestyle, really. I intend to eat whatever feels right to me, just so happens, that's raw right now. I think, instead, it's best to strive for "nutritional excellence" as Dr.Fuhrman calls it, rather than some sort of ideal which may or not be nutritionally sound. Is there anything more annoying when you have a headache or something and a raw foodists jumps in with, "It's DETOX!!"
I did the high-fruit, low fruit, high-protein, high carb -- everything you can think
. But what works for me at the mo, is high-greens, then fruit, then fats, no grains -- basically, Fuhrman diet, but raw. This is why I constantly promote green smoothies! Greens were the key for me. The only way I can eat that much (for reasons such as time!) is to make the smoothies.
If I felt as you -- that it was raw that was no longer working -- I'd not hesitate to eat something nutritious, cooked. In fact, I intend to do so when or if that day comes. I never believed "cooked food is poison!" At least not all is.
Your ratios look pretty good to me, actually...are you sure it is the diet? It could be. Everyone is so different with different histories, different constitutions that there is no one-size-fits-all diet! But striving for alkalinity is also important. I wrote about it a few posts ago in my journal, though it is mostly ramblings about my own experiments
