The thing about carbohydrates the more you consume them the more you want them. It's a mental thing rather than a body thing.
So my first advice would be to limit them under 50grams a day and see how much you crave them after a few days.
If you are still craving more carbohydrates I would limit them down to 40grams a day and see how you fare.
I haven't tried every diet but the one I had the most success on wasn't a diet. It was a lifestyle the Primal Lifestyle.
