Lows are to be respected, not feared.

A great benefit of low-carb eating is that a diabetic will no longer experience crashing lows like they did when they were eating large amounts of carbohydrates and using large amounts of insulin. When eating low-carb, lows tend to be very gradual, and since you are following the Law of Small Numbers, your body only requires a very small correction to get to the ideal blood glucose level of 83 mg/dL.
