Irene, welcome. I’m afraid I’m a bit confused by your post. Perhaps you could clarify for me. Are you currently using insulin or not? What won’t clinic be happy about? Are you currently using or have you tried low carb?
For us to be able to make useful suggestions we need to know what type of diabetes you have. Also things like how long you’d have it, how it was diagnosed (which tests), what sort of diets you have tried and currently use, and what your daily and hb1ac blood sugar levels are like. The answers to these can give us some idea of what might help.
