The problem with insulin (apart from the injections!) is that being a T2 we are already insulin resistant so you usually end up with ever increasing doses and the problem gets worse. I struggle with my glucose even on a low card diet but I know I would be a lot worse if I wasn't very careful with my diet.
That has been a worry of mine for a long time, I get told I need to lose weight but yet get told that insulin can cause weight gain.
Are you in Insulin?
