I have recently started a low carb diet and also taking metformin. I am a type 2 diabetec. I recently came off insulin because I felt it was doing me no good as I had put 4 stone on in 9 months and always felt I had no energy. I go running 3 times a week and do 6 miles at a time. My sugar levels are around 16-19 daily and are not coming down can anybody HELP.
