Peter also remarks that a high FBG in a low carber is just a temporary IR state. As soon as you eat something you lose the IR and deal with the incoming glucose/protein and your post-meal BG will be shiny.

He states the difference is that a diabetic is permanently IR because they have high insulin levels and low carber is just IR when they're fasting and only because they have such low insulin levels.

So how do you know which sort you are? I suppose get a fasting insulin test next time they check your fasting BG.
