According to what I have read (and some sources vary in their numbers...), morning fasting for non-diabetics if less than 100. The "goal" for diabetics is between 90 and 130 - and again that depends on the many sources on the Web, books and the doctors' offices. I'm presuming they mean diabetics who take meds. I don't take any medication and the only way I have morning fasting numbers under 100 is if I don't eat any carbohydrates (no bread, rice, potatoes, pasta, cake) the night before. If a person's fasting number is between 100 and 126, doctors would consider this "pre-diabetic". I tried the snack of a protein like peanut butter and a graham cracker or some slices of apple at night but I still had fasting numbers between 110 and 125, so I stopped the snacks. I have found though that having nuts and strawberries (just handfuls) after dinner don't affect my fasting numbers - still average about 90.
My husband's morning level was 106 this morning!!! That is the best it has been in the am for a couple of months. His physician said some of his other meds are actually raising his blood sugar levels but we tried the nighttime snack of celery with cheese whiz or toast with peanut butter and both of these seem to help with the morning numbers.
Thanks so much for everyone's input.
