That sounds like the monkey diet, which I advocate and helped invent. The monkey diet is much better than your carb free thing, yesno, because you only eat fruit. NO VEGETABLES and no nuts! There's nothing to think about. Hungry? Eat some fruit. Still hungry? Eat some more fruit.
I've never been able to stick to it for very long, but it sounds like you might have what it takes. Would you give it a try and let me know?
