The Diabetes Code: Prevent and Reverse Type 2 Diabetes Naturally

by Jason Fung

Your physician can direct you on how to reduce or hold diabetic medications, and especially insulin, during fasting days. They can be taken on an as-needed basis when blood glucose goes too high. Modestly elevated blood glucose is not often a problem, since it can be expected to come down with fasting. In my Intensive Dietary Management (IDM) program, for example, the target blood glucose is 8.0 to 10.0 mmol/L while fasting, if you are taking medication. This range is higher than the non-fasting norm. Mildly elevated blood glucose levels are not harmful in the short term, and this higher range creates a margin of safety to prevent the far more dangerous hypoglycemic reactions. I consider this to be an acceptable trade-off. The long-term goal is to successfully reduce and then stop all medications and still be able to maintain your sugars in the normal range.
