As a diabetic, I might be able to answer some of your questions, even the ones you haven't asked yet.

First of all, many of the docs act like they have the answers and they don't. There is still a lot about diabetes they don't know.

Our cells need carbs. I view carbs as cellular go juice. Without it, we crash.

I learned in the last two years that the liver stores sugars in case of emergency. It will make a sugar dump if you get hungry or need to eat for energy. What medical science has recently learned is that sometimes the liver makes a sugar dump when it isn't needed. This raises your blood sugar. This is one of the reasons type two diabetics have difficulty controlling blood sugar levels. I have found that if my sugar is high in the morning, I take my medicine and I still eat. Even without the medicine, my blood sugar usually comes down if I eat correctly.

Exercise is essential. What the docs won't tell you is that your body doesn't need insulin to process carbs if you are exercising or very active. The insulin is used when your body is inactive, such as sleep. Too much inactivity leads to too much insulin use, and thus you develop insulin resistant diabetes.

In short:
You have to eat regular meals or you liver will dump sugar and the sugar level might go up. The less exercise you get, the more insulin you need. This also means you need to eat more high carb foods to get energized. This is a never-ending cycle.

Good luck with your health and I hope I didn't confuse you. I also have thyroid issues. I hope that yours can be easily treated with medicine. Female hormones also mess with the thyroid and weight loss and vice-versa. It's so complicated.
