I have pre DB with my A1c 7.0, and my glucose tolerance fasting was 101 and the 2nd blood draw was normal. I find it confusing to have the A1c say I am DB, and the glucose tolerance coming back as normal. I gained 20 lbs over the last year, and I can't seem to loose it. I walk 20 minutes on the treadmil daily, and do power yoga 3 to 4 times a week, any suggestions. Also, I am not on medication and my doctor feels I can control the DB through diet and exercise. Any diet suggestions?
