I was diagnosed in 1985. I don't know what my glucose tolerance test reading was at the time - A1c had not been invented yet. I have been eating a low-carb, high fat diet since 2004. I was able to get my A1c down to 6% which resulted in a weight of between 160-165 lbs. But no matter what I did, I could not quite achieve a normal A1c and my weight would go no lower. So I would get frustrated and eat poorly and both would go back up. This cycle has continued over the years. I have been able to stay on only Metformin for medicine over the years. In February of 2017, I was not doing well. My endocrinologist had decided to concentrate on thyroid a few years previously and I was the only diabetic he still treated. He recommended I go to some else who would be keeping up with the literature on diabetes as he really didn't, and made a suggestion for someone to see. After my visit with the new doctor, I realized I was feeling bad all the time (a lot of this was due to stress eating at work). The new doctor wanted to put me on another medicine. She agreed that diet was the best way to handle this (she does low carb herself), but thought that until I retired and could quit stress eating the new med would help. I was due to retire in January 2018 and decided I could not wait until then to take control again. I took the preliminary dose of the medicine for a week, but then quit. The prescribing information indicated that I could achieve better results, and quicker, doing what I had done in the past. This time I added intermittent fasting as described in Dr. Jason fund's book to my LCHF diet. I did it the easy way, by compressing my eating time to a period of 8 hrs. This is easiest done just by skipping breakfast, though my results are best if I skip dinner instead. As I got used to fasting. I would sometimes eat only 1 meal a day - never having a problem with hunger (you have to be eating a LCHF diet for this to be really effective). As of today, my A1c is 5.5%, my weight is 140 lbs. and I am not on any diabetes medicine.
