So OK I've always been a mean and nasty grouch since I was about 14 years of age. I was even grouchier on induction, but now I'm about a +1 on the grouch meter (out of 10). I have never been less grouchy, irritable or depressed than since adopting a low-carb paleo lifestyle.

At least there was more than one opinion expressed in this article which is progress I suppose.
