Here are some confusing positions within the low carb world.

1. High protein is good (Ted Naiman)/high protein is bad (Ron Rosedale)

2. Vegetables are beneficial (Terry Wahls)/ Vegetables are harmful (Georgia Ede)

3. Fasting is beneficial (Jason Fung)/Fasting is harmful (Stephen Phinney)

This of course is a vast simplification of the controversies and it leaves out lots of others who fall on one side or the other of the controversies (or somewhere in the middle). It leaves a person without a clear direction in which to go. I take my best guess and try not to obsess too much about it. I am not always successful with that.
