I have been working on weight loss for 1 year. I was obese and still am but I am down 54 lbs. My A1C, at 37 lbs down and 6 months of diet and exercise, was 5.9. I just tested again, after another 6 months and now 54 lbs lost and my A1C is still 5.9. I have been on a low carb eating program, self dictated, in the past 6 months I have increased my exercise to 1 hour walking daily. If the weather is too bad to go to the mall and walk, I use a recumbent bike for 45 min to 1 hour on those days. Obviously I still have more weight to lose and will keep working on it, but my body is not cooperating. I am barely losing 1-3 lbs a month, now. All this being said, the A1C result after all this work, didn t move even .1. Other than taking medication, why won t my A1C go down?
