When I plateaued (not a diabetic) I found that three things really made the difference. 1.) I logged everything I ate whether it embarrassed me or not. 2.) I weighed myself every morning before I ate or drank anything. 3.) I weighed all my foods. Unless there's no way of avoiding measuring it, it was weighed. Do those to start with. The weighing of all the food particularly was a really eye opener. People in the medical profession are still humans. I'm always amazed by the level of obesity among them and how many are smokers and drinkers.
