Dr Shawn Baker. I found this very interesting because of a post quite some time back from a person here on KT that was doing something called the "Snake" diet. He was showing really low blood sugar levels. Dr Baker explains how low blood sugar levels on a high carbohydrate diet is quite a different thing that on a low carb or especially zero carb diet. Not all blood sugar levels are created equal.
