hi Judy,

I think perhaps the dr. was trying to suggest that something is destroying your insulin-producing cells in the pancreas, which would lead to diabetes. This is extremely unlikely, since your blood sugar is normal. If you were becoming diabetic, your blood sugar would be very high, even if you had been eating a low-carb diet. Low insulin levels associated with diabetes come as a late sign, and other symptoms would show up much sooner .. high sugars, high insulin .. weight gain, elevated blood lipids etc etc . all the symptoms of insulin resistance.

More likely, as Lila suggested .. your insulin levels are low because you're low-carbing AND .. you were fasting. Especially if you'd been fasting for more than 12 hrs. It will be good to see an Endocrinologist; perhaps she or he can also do a fasting glucagon test. In fasting/starvation, your insulin would be low, and glucagon would be high. Glucagon will trigger the liver to release stored glycogen, which would keep your blood sugar in the normal range so that it doesn't drop too low.

As for your question about insulin sensitivity .. HIGH fasting insulin levels are the hallmark of insulin resistance.

My suggestion is that you continue to follow the Schwarzbein program as you have been doing. Make sure that you are in fact eating the amount of carbs that you should be for your level .. the lowest would be 15g per meal and 7g per snack. Don't skip meals.

hth,
