Alright, so my boyfriend does a "no carb" diet. The reason I say it that way, is because he eats plenty of carbs... but he's choosy. By not eating the main four (bread, potatoes, pasta, and the fourth one which I always forget) he can eat all of the other carbs that a normal person eats, but he stays very skinny. He's been doing this for about 8 years now and is in great shape. Because I live with him, I'm sort of forced to live a similar diet. I must say, after not eating pasta for two years, I can no longer eat it. It hurts my stomach really bad. It's just too much food.
