They're simply not, the body can manufacture all the glucose it needs.
The ketogenic diet is glucose sparing, that is your insulin levels are dramatically lowered since the very small amount of glucose you're eating should go to the tissues that require it, not into your fat cells.
So if you're on a ketogenic diet and then eat a lot of glucose, your body takes a little while to ramp back up insulin. That's not the same thing as insulin resistance or impaired insulin production in diabetics.
