I occasionally get emails and tweets admonishing me for being hostile to paleo and low-carb, having moved on and having to take a glancing blow behind me. It’s not an unfamiliar experience– I received the same when I stopped being vegan.
The truth is that I’m not hostile to paleo, low-carb, or vegan. All three represent food subcultures that taught me a lot about food and how it affects my health. I am thankful for that. Unfortunately all have quasi-religious underpinnings that can be detrimental to health. They are also hostile to critics.
