Thank you for your response. I am watching my A1C and my glucose daily. After 8 months of eating the way I described, both values were still not in range. My A1C was 5.7 and my fasting glucose was 100-115. Not terrible, but my goal was in range, under 100. Only when I started 21DSD and gave up stevia and dairy did my fasting come under 100. I am very happy with that, but not convinced that 21 days is going to effect a permanent change.
As far as exercise, I have been exercising 6 days a week for the last 5 months (I have chronic fatigue and before that time I was in a chair all day.) For the last 6 weeks I have been doing high intensity intervals (Peak8) three days a week, and intense strength training the other three days (a knock-off of P90X, but only about 30″ per).
Thanks again for the help.
