This is very useful to your goal.
I've tried Bernstein for a considerable time in fact, and I found it to be no different (almost suspiciously so) to attempting a low calorie diet.
Your regular basal rates will likely not apply in every instance any more, and you'll want to ease into things to gather your bearings
Likewise, if you're finding it tough to adhere to and maintain, you'll find the opposite will happen once you break down and veer off and away from the diet (eating more carby more 'regular' food), and you'll have some pretty explosive glucose spikes.
It seems as though almost any simplified diet can have similar attributes to super low carb. The lack of complexity can lead to some super stable glucose patterns. Now I'm at the other end of it, for the time being, I do find myself questioning his theories in some regards, and wonder now if it could really be just as simple as, a simpler diet with super slow absorbing carbs has extremely predictable results, not just a very low carb one.
