Hi
@Veryanxious,
When did you see these spikes of 160 mg (8.9 mmol) or 180mg/dl (10 mmol)? Was this two hours after eating or was this earlier than this?
The guidelines for an OGTT say that in order to be diagnosed as diabetic, your blood sugars should be in excess of 11 mmol two hours after ingesting the glucose load. So, I am not convinced that what you saw were really diabetic levels.
Did you see these spikes after having embarked on low carb way of eating?
If yes, I agree with
@HSSS that this might be due to the last meal effect or physiological insulin resistance (which is reversible) once you start eating carbs again. It is not even unheard of for non-diabetics to spike to this level after food.
There is another thing I am curious about. Did you have the fasting insulin test while low-carbing? Did you know that low-carb lowers circulating insulin in everyone generally? Could the low fasting insulin be a sign that your body didn't require as much insulin rather than a sign that it can't produce enough insulin? It would be interesting to see what your fasting insulin levels are after changing to a high carb low fat way of eating.
This being said, I am keeping my fingers crossed that HCLF works for you. Would be happy if you decide to keep us updated.
