Generally people have zero understanding, had a guy at work wanting to drop some weight, so he came to work all excited about the Atkins diet, at lunch he was having a huge feed of Chinese take away, when I pointed out the rice contains carbs, he looked at me like I was an idiot, and replied,"There is nothing in rice, Chinese people eat rice all the time and they are skinny." I just left it at that. The following day he had KFC and still thought he was on low carbs.
