Again some carb phobia saying different things but in the end the answer is this:
Carbs are not bad for you, and people still don't seem to understand that. There are less of these people than before, but there still are people who will get mad at you for having a piece of fruit because they think it is bad.
Yes, there are probably some who can't have fruit for whatever reasons; but fruit and carbs (rice, potatoes) are not bad for you. The idea of paleo/primal is not low-carb, and some have made people think that. The idea is eating natural like our ancestors used to eat and the idea is good health. If there was rice, they would eat rice. They had a mix of different things that gave them maximum nutrition, along with energy.
Ketosis is a survival adaptation and is not considered healthy longterm. Just sayin'. Flame away.
