I think the raw food diet is just hard to stick too. I've done many high raw days and in fact many raw foodists I know eat 80% raw food. I hate eating raw foods during winter as that is not what my body craves. During summer, I love lots of raw fruits and vegetables. I love cooked beans though and cooked beans are low glycemic, full of fiber and contain protein. I also just felt really bad eating raw, I know raw foodists will say its toxins leaving your body but it isn't.
You can't out-exercise poor eating habits.
