I had carb craving all-day long even after eating 2000+ calories. I was between 50g and 100g of carb per day (as recommended by Mark's Daily Apple and some others). At the end I feel bad, always tired (exact opposite than at the beginning) and I got very sick for a month (first time in my life).
I'm now eating fruits and protein (no wheat, gluten, processed food) and sometimes dairy. I feel far better for more than a year now (without fluctuations like with paleo). I've gained some weight (because my metabolism was really low) but I'm now dropping weight without any change. It is a long-term diet I'm not expecting to drop 10 pounds in a month (I've tried paleo again for a week recently and didn't even lost a pound BTW).
30lb/9 month is pretty impressive, good luck with your endeavours!
